相關技術的討論 Discussion of related technologies

傳統上眼用鏡片(如隱形眼鏡或人工水晶體)提供一預定的光學特性。例如，隱形眼鏡可以提供以下的一或多者：視力矯正功能；加強妝飾；和治療效果，但僅有一組視力矯正功能。每種功能係由鏡片的一種物理特性所提供。基本上，結合折射特性之鏡片設計提供視力矯正功能。將色素結合至鏡片可提供加強妝飾效果。將活性劑結合至鏡片中可提供治療效果。 Traditionally used ophthalmic lenses, such as contact lenses or artificial crystals, provide a predetermined optical characteristic. For example, a contact lens can provide one or more of the following: vision correction function; enhanced makeup; and therapeutic effects, but only one set of vision correction functions. Each function is provided by a physical property of the lens. Basically, a lens design incorporating refractive properties provides vision correction. The incorporation of pigment into the lens provides a reinforced look. The incorporation of the active agent into the lens provides a therapeutic effect.

目前已將眼用鏡片的光學特性設計成鏡片的物理特性。一般來講，光學設計已經確定，然後在鏡片的製造過程中(例如，透過澆鑄模塑或車床加工)將其應用於鏡片中。鏡片一經形成，鏡片的光學特性即保持固定。然而，佩戴者有時會發現若有不止一個焦度可供使用以提供視力調節會是有益的。眼鏡佩戴者可透過更換眼鏡來改變光學矯正，但與眼鏡佩戴者不同的是，隱形鏡片佩戴者或人工水晶體使用者需付出更大的努力或是在隱形眼鏡或人工水晶體在補償眼鏡的情況下，才能改變其視力矯正的光學特性。 The optical properties of ophthalmic lenses have been designed to be the physical properties of the lenses. In general, the optical design has been determined and then applied to the lens during the manufacture of the lens (eg, by cast molding or lathe processing). Once the lens is formed, the optical properties of the lens remain fixed. However, the wearer sometimes finds it beneficial to have more than one power available to provide vision adjustment. Glasses wearers can change the optical correction by changing the glasses, but unlike glasses wearers, contact lens wearers or artificial crystal crystal users need to work harder or in the case of contact lenses or artificial crystals in the compensation glasses. In order to change the optical properties of its vision correction.

因此，本揭露包括關於具有液晶元件的可變光學插件的創新，該可變光學插件可經賦能並結合到眼用裝置中，如此能夠改變眼用裝置的光學特性。此類眼用裝置的實例可包括隱形眼鏡或人工水晶體。此外，本文提出了用於形成具有含液晶元件的可變光學插件的眼用鏡片之方法及設備。一些實施例還可包括具有剛性或可形成的經賦能插件(其另外包括可變光學部分)的澆鑄模塑的聚 矽氧水凝膠隱形眼鏡，其中插件以生物可相容方式包括在眼用鏡片內。 Accordingly, the present disclosure includes an innovation regarding a variable optical insert having a liquid crystal element that can be energized and incorporated into an ophthalmic device such that the optical characteristics of the ophthalmic device can be altered. Examples of such ophthalmic devices can include contact lenses or artificial crystals. In addition, methods and apparatus for forming an ophthalmic lens having a variable optical insert containing a liquid crystal element are presented herein. Some embodiments may also include cast molded poly having a rigid or formable energized insert that additionally includes a variable optical portion Hydroxyl hydrogel contact lenses in which the insert is included in the ophthalmic lens in a biocompatible manner.

因此，本揭露包括具有可變光學插件的眼用鏡片、用於形成具有可變光學插件的眼用鏡片的設備、及其製造方法。可將能量源置於或裝配於可變光學插件上，並可將該插件放置於鄰近第一模具零件和第二模具零件其中之一者或兩者處。將包含反應性單體混合物(下文將以反應性單體混合物稱之)的組成物放置於第一模具零件和第二模具零件之間。將第一模具零件鄰近第二模具零件定位藉以形成一鏡片腔穴，該鏡片腔穴中具有經賦能的媒介插件和至少一些反應性單體混合物；使該反應性單體混合物暴露於光化輻射中以形成眼用鏡片。透過控制反應性單體混合物所暴露的光化輻射來形成鏡片。在一些實施例中，眼用鏡片裙件或插件封裝層包含標準水凝膠眼用鏡片配方。具有可提供對許多插件材料之可接受匹配之特性的例示性材料可包括，例如Narafilcon系列(包括Narafilcon A和Narafilcon B)、Etafilcon系列(包括Etafilcon A)、Galyfilcon A和Senofilcon A。 Accordingly, the present disclosure includes an ophthalmic lens having a variable optical insert, an apparatus for forming an ophthalmic lens having a variable optical insert, and a method of making the same. The energy source can be placed or mounted on a variable optical insert and the insert can be placed adjacent one or both of the first mold part and the second mold part. A composition comprising a reactive monomer mixture (hereinafter referred to as a reactive monomer mixture) is placed between the first mold part and the second mold part. Positioning the first mold part adjacent to the second mold part to form a lens cavity having an energized media insert and at least some reactive monomer mixture in the lens cavity; exposing the reactive monomer mixture to actinic Radiation is used to form an ophthalmic lens. The lens is formed by controlling the actinic radiation exposed by the reactive monomer mixture. In some embodiments, the ophthalmic lens skirt or insert encapsulation layer comprises a standard hydrogel ophthalmic lens formulation. Exemplary materials having properties that provide acceptable matching to many insert materials can include, for example, the Narafilcon series (including Narafilcon A and Narafilcon B), the Etafilcon series (including Etafilcon A), Galyfilcon A, and Senofilcon A.

形成具有液晶元件的可變光學插件的方法和所得的插件是本發明各種實例的重要態樣。在一些實例中，液晶可位於兩個配向層之間，而該等配向層可設定液晶的靜止定向。在一些實例中，可以各種方式圖案化配向層。可執行配向層的圖案化，使得配向層中的分子配向與液晶分子相互作用以形成從鏡片中央中的第一定向至鏡片邊緣處或附近的第二定向的一平滑變化圖案。該平滑變化圖案可歸類為一梯度圖案，且由於液晶分子的定向會影響該層的有效折射率，因此該平滑變化圖案也可歸類為形成一梯度折射率圖 案。可透過沉積於含有可變光學部分的基材層上的電極使這兩個配向層與能量源電連通。可透過連接至能量源的中間互連件或直接透過嵌入插件中的組件對電極賦能。在一些實例中，一介電層可形成為鄰近電極，其中介電層至少在位於所得裝置之光學區的部分中的厚度上發生變化。 The method of forming a variable optical insert having a liquid crystal element and the resulting insert are an important aspect of various examples of the present invention. In some examples, the liquid crystal can be positioned between two alignment layers, and the alignment layers can set the static orientation of the liquid crystal. In some examples, the alignment layer can be patterned in a variety of ways. Patterning of the alignment layer can be performed such that molecular alignment in the alignment layer interacts with the liquid crystal molecules to form a smoothly varying pattern from a first orientation in the center of the lens to a second orientation at or near the edge of the lens. The smooth change pattern can be classified into a gradient pattern, and since the orientation of the liquid crystal molecules affects the effective refractive index of the layer, the smooth change pattern can also be classified as forming a gradient index map. case. The two alignment layers can be in electrical communication with the energy source through electrodes deposited on the substrate layer containing the variable optical portion. The electrodes can be energized through intermediate interconnects connected to the energy source or directly through components embedded in the insert. In some examples, a dielectric layer can be formed adjacent the electrodes, wherein the dielectric layer varies at least in thickness in portions of the optical regions of the resulting device.

電極層的賦能可造成液晶(其可以一梯度折射率圖案圖案化)從靜止定向轉換至賦能定向。在具有通或斷兩種賦能操作的實施例中，液晶可僅具有一種經賦能定向。而在賦能係根據能量位準級別產生之其他替代性實施例中，液晶可具有多種經賦能定向。亦可衍生出其它實施例，其中賦能過程透過賦能脈衝可造成不同狀態間的切換。在存在一介電層鄰近電極之情況中，電極的賦能可引起橫跨含液晶層之電場之一成形變化。可藉由控制介電厚度之厚度變化來程式化電場變化之成形，並且成形可具有電場之所有變化，該變化允許所施加至電極之一特定電位依介於未施加電場與使相鄰液晶層完全沿電場配向的一大施加電場之間之一中間電壓建立一聚焦條件。 The energization of the electrode layer can cause the liquid crystal (which can be patterned by a gradient index pattern) to switch from a stationary orientation to an energization orientation. In embodiments having both on or off energization operations, the liquid crystal may have only one energized orientation. While other alternative embodiments in which the energization is based on the energy level level, the liquid crystal can have a plurality of energized orientations. Other embodiments may also be derived in which the energization process can cause switching between different states by energizing pulses. In the presence of a dielectric layer adjacent to the electrode, energization of the electrode can cause a change in shaping of one of the electric fields across the liquid crystal containing layer. The shaping of the electric field change can be programmed by controlling the thickness variation of the dielectric thickness, and the shaping can have all of the changes in the electric field that allow a particular potential applied to one of the electrodes to be between the unapplied electric field and the adjacent liquid crystal layer. An intermediate condition is established between an applied electric field that is completely aligned along the electric field.

所得到的分子配向和定向會影響穿過液晶層的光，因而造成可變光學插件的變化。例如，配向和定向可以將折射特性作用於入射光。另外，該效應可包括光偏振的改變。一些實施例可包括可變光學插件，其中賦能改變鏡片的聚焦特性。 The resulting molecular alignment and orientation affects light passing through the liquid crystal layer, thus causing variations in the variable optical insert. For example, alignment and orientation can apply refractive properties to incident light. Additionally, the effect can include a change in light polarization. Some embodiments may include a variable optical insert in which energization changes the focus characteristics of the lens.

在一些實施例中，液晶層可以會引起包含液晶分子的可聚合混合物發生聚合之方式形成。用於形成聚合物基質的單體自身可包含所連接的液晶部分。藉由控制聚合反應並且包括未連接到單體化合物的液晶分子，可形成交聯聚合物區域的基質，該等交聯 聚合物區域涵蓋個別液晶分子所定位的區域。在一些術語中，交聯聚合分子與包含間隙的液晶分子的此類組合可稱為網狀配置(network arrangement)。配向層可引導連接到單體的液晶分子配向，使得網狀聚合材料配向至引導配向層。在一些實例中，可存在藉由各種方式形成在配向層中的一平滑變化圖案，其接著可使液晶分子或網狀液晶材料形成梯度折射率圖案。在聚合期間，所連接的液晶分子被鎖定至一定向，然而，經間隙定位之液晶分子可在空間中自由定向。當不存在外部影響時，自由液晶分子之配向將受到已配向液晶分子基質的影響。 In some embodiments, the liquid crystal layer may be formed in such a manner that a polymerizable mixture containing liquid crystal molecules is polymerized. The monomers used to form the polymer matrix may themselves comprise the liquid crystal moieties attached. By controlling the polymerization reaction and including liquid crystal molecules not attached to the monomer compound, a matrix of the crosslinked polymer region can be formed, which crosslinks The polymer region covers the regions in which individual liquid crystal molecules are located. In some terms, such a combination of a crosslinked polymeric molecule with a liquid crystal molecule comprising a gap can be referred to as a network arrangement. The alignment layer can direct the alignment of the liquid crystal molecules attached to the monomer such that the networked polymeric material is aligned to the directed alignment layer. In some examples, there may be a smooth varying pattern formed in the alignment layer by various means, which may then cause the liquid crystal molecules or the network liquid crystal material to form a gradient index pattern. During the polymerization, the attached liquid crystal molecules are locked to a certain direction, however, the gap-aligned liquid crystal molecules can be freely oriented in space. When there is no external influence, the alignment of the free liquid crystal molecules will be affected by the matrix of the aligned liquid crystal molecules.

因此，在一些實施例中，眼用裝置可藉由在其內結合一包含液晶分子的可變光學插件形成。可變插件可包含可位於眼用裝置光學區中的至少一部分。可變插件可包含前插件部和後插件部。在一些實例中，可將液晶分子配向成一圖案，使得其中在光學插件的至少第一部分上的折射率可隨徑向相依性而變化。該徑向相依性可對徑向距離具有一主要為拋物型之相依性，且在一些實例中，該徑向相依性可從光學裝置的中央對徑向距離具有拋物型和更高階參數相依性。 Thus, in some embodiments, an ophthalmic device can be formed by incorporating a variable optical insert comprising liquid crystal molecules therein. The variable insert can include at least a portion that can be located in the optic zone of the ophthalmic device. The variable plug-in can include a front plug-in portion and a rear plug-in portion. In some examples, the liquid crystal molecules can be oriented in a pattern such that the index of refraction therein on at least a first portion of the optical insert can vary with radial dependence. The radial dependence may have a predominantly parabolic dependence on the radial distance, and in some instances, the radial dependence may have parabolic and higher order parameter dependencies from the center to radial distance of the optical device. .

The dielectric layer can be positioned adjacent at least one of the curved front insert portion and the curved rear insert portion, wherein the dielectric layer changes at least in a thickness in the portion of the optical zone.

在一些實施例中，包含液晶材料的梯度折射率層可能夠造成補充插件表面的不同半徑之效應的光學效應。 In some embodiments, a gradient index layer comprising a liquid crystal material can be capable of causing an optical effect that complements the effects of different radii of the surface of the insert.

在一些實施例中，眼用裝置可以是隱形眼鏡。 In some embodiments, the ophthalmic device can be a contact lens.

The first electrode may be located adjacent the rear surface of the front curved portion, and the second electrode may be located adjacent the front surface of the rear curved portion. When a voltage is applied across the first and second electrodes, an electric field can be established on the liquid crystal layer between the electrodes. Applying an electric field to the liquid crystal layer can cause free liquid crystal molecules within the layer to physically align with the electric field. In some embodiments, free liquid crystal molecules can be positioned in the interstitial regions within the network polymer, and in some embodiments, the polymer backbone can contain chemically bonded liquid crystal molecules that can be polymerized during polymerization.

本揭露包括用於製造具有可變光學插件的眼用鏡片的方法和設備，其中可變光學部分由液晶或自身包括液晶成分的複合材料所構成。此外，本揭露包括具有可變光學插件的眼用鏡片，該可變光學插件由液晶構成並結合到該眼用鏡片中。 The present disclosure includes a method and apparatus for making an ophthalmic lens having a variable optical insert, wherein the variable optical portion is comprised of a liquid crystal or a composite material that itself includes a liquid crystal composition. Moreover, the present disclosure includes an ophthalmic lens having a variable optical insert that is constructed of liquid crystal and incorporated into the ophthalmic lens.

根據本揭露，眼用鏡片由嵌入式插件和能量源形成，該能量源諸如用作能量儲存裝置的電化學電池或電池。在一些實例中，可將包含能量源的材料封裝並與放置眼用鏡片的環境隔離。在一些實例中，能量源可包括可在主要或可再充電組態中使用的電化學電池化學物質。 In accordance with the present disclosure, an ophthalmic lens is formed from an embedded insert and an energy source, such as an electrochemical cell or battery used as an energy storage device. In some examples, the material containing the energy source can be packaged and isolated from the environment in which the ophthalmic lens is placed. In some examples, the energy source can include electrochemical cell chemistries that can be used in a primary or rechargeable configuration.

可使用由佩戴者控制的調整裝置來改變光學部分。調整裝置可包含例如用於增加或減小電壓輸出或者與能量源接合和脫離的電子裝置或被動裝置。一些實例還可包括自動調整裝置以透過自動設備根據測得參數或佩戴者輸入來改變可變光學部分。佩戴者輸入可包括例如由無線設備所控制的開關。無線可以包括例如射頻控制、磁開關、構成圖案的光發射以及電感切換。在其他實例中，可回應於生物功能或回應於眼用鏡片內的感應元件的測量值而發生啟動。其他實例可因受環境照明條件的變化所觸發(作為非限制性實例)而啟動。 The optical portion can be changed using an adjustment device controlled by the wearer. The adjustment device can include, for example, an electronic device or a passive device for increasing or decreasing the voltage output or engaging and disengaging the energy source. Some examples may also include an automatic adjustment device to change the variable optical portion based on the measured parameter or wearer input through the automated device. The wearer input can include, for example, a switch controlled by the wireless device. Wireless can include, for example, radio frequency control, magnetic switches, patterned light emissions, and inductive switching. In other examples, activation may occur in response to biological function or in response to measurements of inductive elements within the ophthalmic lens. Other examples may be initiated as a result of changes in ambient lighting conditions (as a non-limiting example).

當電極經賦能所形成的電場導致液晶層內重新配向從而使分子從靜止定向轉變為經賦能定向時，光學功率(optic power)可發生變化。在其他替代實例中，可利用因藉電極賦能的液晶層的變化所導致的不同效應，例如，改變光偏振狀態，特別是偏振旋轉。 The optic power can change when the electric field formed by the energization of the electrode causes realignment within the liquid crystal layer to cause the molecule to transition from a stationary orientation to an energized orientation. In other alternative examples, different effects due to variations in the liquid crystal layer energized by the electrodes may be utilized, for example, changing the polarization state of the light, particularly polarization rotation.

在具有液晶層的一些實例中，在眼用鏡片的非光學區部分中可能存在可經賦能的元件，而其他實例可不需要賦能。在不進行賦能的實例中，液晶可基於一些外部因素，例如環境溫度或環境光線而被動地變化。 In some instances having a liquid crystal layer, there may be an energizable element in the non-optical zone portion of the ophthalmic lens, while other examples may not require energization. In an example where no energization is performed, the liquid crystal can be passively varied based on some external factors, such as ambient temperature or ambient light.

液晶鏡片可向入射到其主體上的偏振光提供電力可變的折射率。其中光學軸定向在第二鏡片中相對於第一鏡片旋轉的兩種鏡片的組合，允許鏡片元件能夠改變環境非偏振光的折射率。 The liquid crystal lens can provide a electrically variable refractive index to polarized light incident on its body. The combination of two lenses in which the optical axis is oriented in the second lens relative to the first lens allows the lens element to change the refractive index of the ambient unpolarized light.

藉由將電活性液晶層與電極組合，可實現可藉施加橫跨電極的電場控制的物理實體。如果在液晶層周邊上存在有介電層，那麼橫跨介電層的場和橫跨液晶層的場可組合成橫跨電極的場。在三維形狀中，可基於電動力學原理以及介電層和液晶層的幾何形狀，來估計橫跨各層的場的組合的性質。如果有效電厚度的介電層以非均勻方式製成，那麼橫跨電極的場的效應可按照介電質的有效形狀「成形」並在液晶層中產生依維度形成的折射率變化。在一些實例中，此類成形可產生能夠採用可變焦特性的鏡片。 By combining the electroactive liquid crystal layer with the electrodes, a physical entity that can be controlled by applying an electric field across the electrodes can be realized. If a dielectric layer is present on the periphery of the liquid crystal layer, the field across the dielectric layer and the field across the liquid crystal layer can be combined into a field across the electrodes. In a three-dimensional shape, the properties of the combination of fields across the layers can be estimated based on electrodynamic principles and the geometry of the dielectric layer and liquid crystal layer. If the dielectric layer of effective electrical thickness is made in a non-uniform manner, the effect of the field across the electrodes can be "shaped" in accordance with the effective shape of the dielectric and produce a refractive index change in the liquid crystal layer that is dimensioned. In some examples, such shaping can result in a lens that is capable of employing zoom characteristics.

當包含液晶層的物理鏡片元件自身成形為具有不同聚焦特性時，可得到替代性實例。於是，根據透過使用電極施加橫跨液晶層的電場，可將液晶層的電力可變的折射率用於引入鏡片的聚焦特性的變化。液晶層的折射率可稱為有效折射率，並且可將有關折射率的各處理視為等同於指有效折射率。有效折射率可例如來自於疊加具有不同折射率的多個區域。在一些實例中，有效態樣可為各種區域性作用的平均值，而在其他實例中，有效態樣可為對入射光的區域性或分子效應的疊加。前容納表面與液晶層構成的形狀以及後容納表面與液晶層構成的形狀可首先決定系統的聚焦特性。 An alternative example can be obtained when the physical lens elements comprising the liquid crystal layer are themselves shaped to have different focusing characteristics. Thus, depending on the electric field applied across the liquid crystal layer by the use of the electrodes, the electrically variable refractive index of the liquid crystal layer can be used to introduce changes in the focusing characteristics of the lens. The refractive index of the liquid crystal layer may be referred to as an effective refractive index, and each process relating to the refractive index may be regarded as equivalent to the effective refractive index. The effective refractive index can be derived, for example, from superimposing multiple regions having different refractive indices. In some examples, the effective aspect can be an average of various regional effects, while in other examples, the effective aspect can be a superposition of regional or molecular effects on incident light. The shape of the front receiving surface and the liquid crystal layer and the shape of the rear receiving surface and the liquid crystal layer may first determine the focusing characteristics of the system.

包括液晶元件的可變光學插件 Variable optical insert including liquid crystal elements

參照圖3A，項目300，可看到兩種不同形狀的鏡片件的鏡片效應的圖示。如之前所提及，本文發明領域的可變光學插件可藉由將電極和液晶層系統封裝在兩種不同形狀的鏡片件內而形成。電極和液晶層系統可佔據如350處所示的鏡片件之間的空間。在320處可找到彎曲前表面，而在310處可找到彎曲後表面。 Referring to Figure 3A, item 300, an illustration of the lens effects of two differently shaped lens members can be seen. As mentioned previously, the variable optical inserts of the present invention can be formed by encapsulating electrodes and liquid crystal layer systems in two differently shaped lens members. The electrode and liquid crystal layer system can occupy the space between the lens elements as shown at 350. The curved front surface can be found at 320 and the curved rear surface can be found at 310.

在非限制性實例中，彎曲前表面320可具有與空間350相互作用的凹形形狀的表面。在一些實例中，該形狀之進一步特徵可為具有被標示為330的曲率半徑和焦點335。可在本發明領域的 範疇內形成具有各種參數特性的其他更複雜形狀；然而，為了說明起見，可描繪一簡單的球形形狀。 In a non-limiting example, curved front surface 320 can have a concave shaped surface that interacts with space 350. In some examples, the shape may be further characterized by having a radius of curvature labeled 330 and a focus 335. Can be in the field of the invention Other more complex shapes with various parametric properties are formed within the category; however, for the sake of explanation, a simple spherical shape can be depicted.

以類似且也非限制性的方式，彎曲後表面310可具有與空間350相互作用的凸形形狀的表面。在一些實例中，該形狀之進一步特徵可為具有被標示為340的曲率半徑和焦點345。可在本發明領域的範疇內形成具有各種參數特性的其他更複雜形狀；然而，為了說明起見，可描繪一簡單的球形形狀。 In a similar and non-limiting manner, curved rear surface 310 can have a convex shaped surface that interacts with space 350. In some examples, the shape may be further characterized by having a radius of curvature and a focus 345 labeled 340. Other more complex shapes having various parametric properties can be formed within the scope of the field of the invention; however, for the sake of explanation, a simple spherical shape can be depicted.

為了解釋如300之類型的鏡片是如何運作，包含彎曲後表面310和彎曲前表面320的材料可具有天然折射率值。在空間350內，可以在非限制性實例中選擇液晶層以匹配該折射率值。因此，當光線橫穿鏡片件以及空間350時，它們對各種界面作用之方式將不會調整聚焦特性。在其功能中，鏡片中未示出的部分可啟動各種組件的賦能，從而可導致空間350中的液晶層對入射光線呈現不同折射率。在非限制性實例中，可降低所得的折射率。現在，在每種材料界面處，可基於表面的聚焦特性和折射率的變化以模型化光路徑而改變之。 To explain how a lens of the type 300, such as 300, operates, the material comprising curved back surface 310 and curved front surface 320 may have a natural refractive index value. Within space 350, a liquid crystal layer can be selected in a non-limiting example to match the refractive index value. Thus, as the light traverses the lens member and the space 350, the manner in which they act on the various interfaces will not adjust the focus characteristics. In its function, portions not shown in the lens can initiate energization of the various components, which can result in the liquid crystal layer in space 350 exhibiting a different index of refraction for incident light. In a non-limiting example, the resulting refractive index can be reduced. Now, at each material interface, it can be changed based on the change in the focus characteristics and refractive index of the surface to model the light path.

該模型可基於司乃耳定律(Snell's law)：sin(θ1)/sin(θ2)=n2/n1。例如，界面可由彎曲前表面320及空間350形成，θ1可以是入射線與在界面處的表面法線所形成的角。θ2可以是光線在離開界面時與表面法線所形成的模型化角。n2可代表空間350的折射率，且n1代表彎曲前表面320的折射率。當n1不等於n2時，則角度θ1和θ2也將不同。因此，當改變空間350中的液晶層的電力可變的折射率時，光線在界面處採取的路徑也將改變。 The model can be based on Snell's law: sin(θ 1 )/sin(θ 2 )=n 2 /n 1 . For example, the interface may be curved front surface 320 and a space 350 is formed, θ 1 and the angle of the incident ray may be a surface normal at the interface formed. θ 2 may be the modeled angle formed by the normal to the surface of the light as it leaves the interface. n 2 may represent the refractive index of the space 350, and n 1 represents the refractive index of the curved front surface 320. When n 1 is not equal to n 2 , the angles θ 1 and θ 2 will also be different. Thus, when changing the electrically variable refractive index of the liquid crystal layer in space 350, the path taken by the light at the interface will also change.

請參照圖3B，圖中繪示具有嵌入的可變光學插件371的眼用鏡片360。眼用鏡片360可具有前曲面370和後曲面372。插件371可具有含液晶層374的可變光學部分373。在一些實例中，插件371可具有多個液晶層374和375。插件371的部分可與眼用鏡片360的光學區重疊。 Referring to FIG. 3B, an ophthalmic lens 360 having an embedded variable optical insert 371 is illustrated. The ophthalmic lens 360 can have a front curve 370 and a back curve 372. The insert 371 can have a variable optical portion 373 that includes a liquid crystal layer 374. In some examples, the insert 371 can have a plurality of liquid crystal layers 374 and 375. Portions of the insert 371 can overlap the optical zone of the ophthalmic lens 360.

參照圖4A，可找到梯度折射率效應的描繪。在具有梯度折射率的實例中，可使用配向層來控制液晶分子的定向。定向的控制本身可控制區域性的有效折射率。因而，液晶分子的定向控制可形成區域性變化的有效折射率，其特徵可在於梯度折射率圖案。在圖4A中，可顯示效應的一例示性描繪，其中將各個元件描繪為平坦元件。儘管有效光學裝置可從平坦元件形成，諸如可用在人工水晶體裝置中，其可形成本文發明領域的部分；也可存在許多亦利用所描述之梯度折射率效應但是形成為三維形狀的實施例。在410，可發現前光學件，其可支撐電極420及配向層425。可藉由各種方式程式化配向層425，一些實例稍後可在本說明書中找到。配向層可具有一程式化的配向，該配向從在440處描繪的與前光學件的表面平行的特徵變化至430處描繪的垂直定向至介於其等之間的定向。配向層程式化定向的效應可以是造成液晶層形成一梯度折射率圖案。液晶分子亦可配向為，其中一些分子的定向平行於前光學表面(諸如在445處所示)，而一些分子的定向垂直於前光學表面(諸如在435處所示)，以及介於兩種極端情況之間的定向或有效定向。對於液晶分子，此變化可造成有效折射率在這些層所形成的光學裝置的光學區中變化或漸變。在一些實例中，可存在一後光學件，如在405處所示。後光學件亦可具有電極層415和配向層426。在一些實 例中，這些配向層可經程式化以呈現與前光學表面上所界定的那些定向類似的定向。 Referring to Figure 4A, a depiction of the gradient refractive index effect can be found. In an example having a graded index of refraction, an alignment layer can be used to control the orientation of the liquid crystal molecules. The directional control itself controls the regional effective refractive index. Thus, the orientation control of the liquid crystal molecules can form a regionally varying effective refractive index, which can be characterized by a gradient index pattern. In FIG. 4A, an exemplary depiction of an effect can be shown in which the various elements are depicted as flat elements. While effective optical devices may be formed from planar elements, such as may be used in artificial crystallographic devices, they may form part of the field of the invention; there may be many embodiments that also utilize the described gradient refractive index effects but are formed into a three-dimensional shape. At 410, a front optic can be found that can support electrode 420 and alignment layer 425. The alignment layer 425 can be programmed in a variety of ways, some examples of which can be found later in this specification. The alignment layer can have a stylized alignment that varies from a feature depicted at 440 parallel to the surface of the front optic to a vertical orientation depicted at 430 to an orientation therebetween. The effect of the stylized orientation of the alignment layer may be to cause the liquid crystal layer to form a gradient index pattern. The liquid crystal molecules can also be aligned such that some of the molecules are oriented parallel to the front optical surface (such as shown at 445), while some molecules are oriented perpendicular to the front optical surface (such as shown at 435), and between Orientation or effective orientation between extreme situations. For liquid crystal molecules, this change can cause the effective refractive index to change or fade in the optical region of the optical device formed by these layers. In some examples, a rear optic may be present, as shown at 405. The rear optic can also have an electrode layer 415 and an alignment layer 426. In some real In an example, the alignment layers can be programmed to present an orientation similar to those defined on the front optical surface.

參照圖4B，可觀察到在液晶層475上施加的電場401的效應。在一些實例中，藉由電極415和420的賦能，可建立電場401。電場401的效應可蓋過具有不同定向(諸如470和480)的配向層部分的效應，從而產生與電場401配向的液晶分子的類似定向，如在475和485處所示。參照圖5A，可***至一眼用鏡片的一可變光學部分500顯示有一液晶層530。可變光學部分500可以具有與本文其他段落中所討論的材料的相似多樣性和結構上的相關性。在一些實施例中，一透明電極545可放置在第一透明基材550上，彎曲第一後表面540可以由一介電膜構成，並且在一些實施例中，由可以放置在第一透明電極545上的配向層構成。在這樣的實施例中，彎曲第一後表面540的介電層的形狀可如圖所示在介電厚度(dielectric thickness)中形成一區域變化的形狀(regionally varied shape)。這種區域變化的形狀可以將鏡片元件的額外聚焦能力(focusing power)引入到如圖3所討論的幾何效應之上。在一些實施例中，例如，成形的層(shaped layer)可以藉由在第一透明電極545基材550組合的射出成型而成形。在一些實施例中，第一透明電極545和第二透明電極520可以用各種方式成形。在一些示範例中，成形(shaping)可導致形成單獨的不同區域，其可能分別施加賦能。在其他示範例中，電極可以形成為圖案，諸如從鏡片的中心到可以在橫跨(遍及)液晶層530上施加一可變電場的外圍的一螺旋。在任一情況下，除了在電極上的介電層的成形或取代這種成形，亦可以執行這種電極成形。以這些方式對電極成形還可以引入鏡片元件在 運作下的額外聚焦能力。一液晶層530可以位於一第一透明電極545以及一第二透明電極520之間。第二透明電極520可以附接到頂基材層510，其中從頂基材層510至底基材層550形成的裝置可以包含眼用鏡片的可變光學部分500。兩個配向層也可以位於介電質上的彎曲第一後表面540及彎曲第一前表面525處並且可以圍繞液晶層530。在彎曲第一後表面540和525處的配向層可以起作用以界定眼用鏡片的一靜止定向(resting orientation)。在一些實施例中，電極層520和545可以與液晶層530電連通且造成從靜止定向到至少一賦能定向(energized orientation)的一定向移位(a shift in orientation)。 Referring to FIG. 4B, the effect of the electric field 401 applied on the liquid crystal layer 475 can be observed. In some examples, the electric field 401 can be established by the energization of electrodes 415 and 420. The effect of the electric field 401 can override the effects of the alignment layer portions having different orientations (such as 470 and 480), resulting in a similar orientation of the liquid crystal molecules aligned with the electric field 401, as shown at 475 and 485. Referring to Figure 5A, a variable optical portion 500 that can be inserted into an ophthalmic lens displays a liquid crystal layer 530. Variable optical portion 500 can have similar diversity and structural correlation to the materials discussed in other paragraphs herein. In some embodiments, a transparent electrode 545 can be placed on the first transparent substrate 550, and the curved first back surface 540 can be composed of a dielectric film, and in some embodiments, can be placed on the first transparent electrode. The alignment layer on 545 is composed. In such an embodiment, the shape of the dielectric layer that bends the first back surface 540 can form a regionally varied shape in the dielectric thickness as shown. This varying shape of the region can introduce additional focusing power of the lens elements onto the geometric effects as discussed in FIG. In some embodiments, for example, a shaped layer can be formed by injection molding of a combination of the first transparent electrode 545 substrate 550. In some embodiments, the first transparent electrode 545 and the second transparent electrode 520 can be formed in a variety of ways. In some examples, shaping may result in the formation of separate distinct regions, which may each apply an energization. In other examples, the electrodes may be formed in a pattern, such as a spiral from the center of the lens to a periphery that may apply a variable electric field across (through) the liquid crystal layer 530. In either case, such electrode formation can be performed in addition to forming or replacing the dielectric layer on the electrode. Forming the electrodes in these ways can also introduce lens elements in Extra focus ability under operation. A liquid crystal layer 530 can be located between a first transparent electrode 545 and a second transparent electrode 520. The second transparent electrode 520 can be attached to the top substrate layer 510, wherein the device formed from the top substrate layer 510 to the bottom substrate layer 550 can comprise the variable optic portion 500 of the ophthalmic lens. The two alignment layers may also be located on the curved first back surface 540 and the curved first front surface 525 on the dielectric and may surround the liquid crystal layer 530. The alignment layer at the curved first back surfaces 540 and 525 can function to define a resting orientation of the ophthalmic lens. In some embodiments, electrode layers 520 and 545 can be in electrical communication with liquid crystal layer 530 and cause a shift in orientation from a stationary orientation to at least one energized orientation.

In a first example, a mixture of monomer and liquid crystal molecules can be formed and the composition heated to form a homogeneous mixture. Next, the mixture can be applied to the insert front curve portion 561 and then encapsulated in the lens insert by adding the insert back curve portion or intermediate curved portion 567. The insert containing the liquid crystal mixture can then be polymerized under predetermined conditions to form a cross-linked region of the polymeric material and an intercalation region of the liquid crystal within the interpolymer gap. In some examples, actinic radiation can be applied to the mixture to initiate polymerization. Prior to and during the polymerization process, the presence of the patterned alignment layer at 563 and 565 can orient the monomer and liquid crystal molecules 564 to form the depicted radially varying pattern. In some examples, there may be transparent electrodes as shown at 562 and 566.

可存在多種將液晶分子結合到聚合或膠凝區域中之方式。因此，形成網狀聚合物液晶層的任何方法可構成本揭露範疇內的技術並且可用於形成眼用裝置，其中形成一梯度折射率徑向輪 廓。先前的實例提到了使用具有經連接液晶部分的單體形成網狀層，該等網狀層形成用於未鍵合液晶分子的間隙位置。聚合物的狀態可以是聚合材料的晶型、半晶型或非晶形式，或在其他實施例中，也可以聚合物的膠凝形式或半膠凝形式存在。 There may be a variety of ways to incorporate liquid crystal molecules into the polymeric or gelled regions. Thus, any method of forming a networked polymer liquid crystal layer can constitute a technique within the scope of the present disclosure and can be used to form an ophthalmic device in which a gradient index radial wheel is formed Profile. The previous examples have referred to the use of monomers having interconnected liquid crystal moieties to form network layers that form gap locations for unbonded liquid crystal molecules. The state of the polymer may be in the crystalline, semi-crystalline or amorphous form of the polymeric material, or in other embodiments, may also be in the gelled or semi-gelled form of the polymer.

In some examples, the first transparent electrode 420 can be placed on the first transparent substrate 410. The first lens surface may be comprised of a dielectric film and, in some instances, an alignment layer that may be placed over the first transparent electrode.

參照圖5C，項目570可代表梯度折射率鏡片的一部分，該部分所包含之液晶以與梯度折射率鏡片一致的方式配向。以折射率隨徑向距離變化之例示性方式，描繪了液晶分子的定向的一些變化。可存在一第一插件部571及一第二插件部576，在其上方具有配向層572和575。該等配向層可引導液晶層573內的液晶分子574的自由站立定向。 Referring to Figure 5C, item 570 can represent a portion of a gradient index lens that contains liquid crystals that align in a manner consistent with the gradient index lens. Some variations in the orientation of the liquid crystal molecules are depicted in an illustrative manner in which the refractive index varies with radial distance. There may be a first insert portion 571 and a second insert portion 576 with alignment layers 572 and 575 thereon. The alignment layers can direct the free standing orientation of the liquid crystal molecules 574 within the liquid crystal layer 573.

參照圖5D，可找到參照圖5C所顯示的包含液晶的梯度折射率鏡片的相同部分。在圖5D中所描繪的情形中，可在包含經配向液晶分子564的層上施加電場，且因而可處於賦能定向。在580處的場向量描繪了電場，且電場是藉由電極層的賦能所建立。顯示液晶分子(例如在581)與所施加電場配向。在此賦能組態中，當層排列而呈現對入射輻射的相對均勻折射率，本質上即抹除了梯度折射率。可存在鏡片表面和形狀的其它光學效應，但藉由排列液晶定向，將產生不同的聚焦特性。 Referring to Figure 5D, the same portion of the gradient index lens comprising liquid crystal shown in Figure 5C can be found. In the situation depicted in Figure 5D, an electric field can be applied to the layer comprising aligned liquid crystal molecules 564, and thus can be in an energizing orientation. The field vector at 580 depicts the electric field and the electric field is established by the energization of the electrode layer. Liquid crystal molecules are shown (eg, at 581) aligned with the applied electric field. In this energized configuration, when the layers are arranged to exhibit a relatively uniform refractive index for incident radiation, the gradient refractive index is essentially erased. Other optical effects of the surface and shape of the lens may exist, but by aligning the orientation of the liquid crystal, different focusing characteristics will result.

請參照圖6，圖中繪示具有兩個液晶層620和640的可***眼用鏡片中的可變光學插件600之一替代例。圍繞液晶區域的各個層的各態樣可具有如相對於圖5A中的可變光學插件500或圖5B中的560所述的類似多樣性。出於例示性目的，將在620和640處的兩個層描繪成具有類似的梯度折射率程式化；但是，在一些其他實例中，可能將梯度折射率型鏡片與另一個液晶元件組合。在一些實例中，多個梯度折射率層之組合可允許以化合方式界定多個聚焦特性。藉由組合第一液晶式元件與第二液晶式元件，可形成(作為一實例)可實現鏡片的電力可變的聚焦特性的一組合，該第一液晶式元件由第一基材610、其在620周圍空間中的中介層和可具有第一聚焦特性之第二基材630所形成，而該第二液晶式元件由第二基材630上的第二表面、在640周圍空間中的中介層和具有第二聚焦特性之第三基材650所形成。 Referring to FIG. 6, an alternative to the variable optical insert 600 in the insertable ophthalmic lens having two liquid crystal layers 620 and 640 is illustrated. Aspects of the various layers surrounding the liquid crystal regions can have similar diversity as described with respect to variable optical insert 500 in Figure 5A or 560 in Figure 5B. For illustrative purposes, the two layers at 620 and 640 are depicted as having similar gradient index stylization; however, in some other examples, a gradient index type lens may be combined with another liquid crystal element. In some examples, a combination of multiple gradient index layers may allow multiple focus characteristics to be defined in a compounded manner. By combining the first liquid crystal element and the second liquid crystal element, a combination of, as an example, a power-variable focusing characteristic of the lens can be formed, the first liquid crystal element being composed of a first substrate 610 An interposer in the space around 620 and a second substrate 630 that may have a first focusing characteristic, and the second liquid crystal element is interposed by a second surface on the second substrate 630, in a space around 640 A layer and a third substrate 650 having a second focusing characteristic are formed.

In other examples, the device can be formed by a combination of four different substrates. In such an example, the intermediate second substrate 630 can be divided into two layers. If the substrates are combined at a later time, a device similar in function to the variable optical insert 600 can be obtained. The combination of four layers may represent an example of a convenient manufacturing component in which similar devices may be constructed around both the 620 and 640 liquid crystal layers, wherein the processing differences may be related to the step portion defining the alignment features of the liquid crystal elements.

液晶材料 Liquid crystal material

可存在多種可具有符合本文已討論的液晶層類型的特性之材料。可以預期的是，具有有利的毒性的液晶材料可為較佳的並且天然來源的膽固醇型液晶材料可以是有用的。在其他實例中，眼用插件的封裝技術和材料可允許廣泛選擇材料，該材料可包括LCD顯示器相關的材料，其通常可為向列型或膽固醇型N或層列型液晶或液晶混合物相關的廣泛類別。市售混合物諸如Merck Specialty chemicals的用於TN、VA、PSVA、IPS和FFS應用的Licristal混合物，以及其他市售混合物可成為形成液晶層的材料選擇。 There may be a variety of materials that may have properties consistent with the type of liquid crystal layer discussed herein. It is contemplated that liquid crystal materials having advantageous toxicity may be preferred and cholesteric liquid crystal materials of natural origin may be useful. In other examples, the encapsulation techniques and materials of the ophthalmic insert may allow for a wide selection of materials, which may include materials related to LCD displays, which may typically be related to nematic or cholesteric N or smectic liquid crystal or liquid crystal mixtures. A wide range of categories. Commercially available mixtures such as Merck Specialty chemicals' Licristal blends for TN, VA, PSVA, IPS, and FFS applications, as well as other commercially available blends, can be a material of choice for forming a liquid crystal layer.

在非限制性意義上，混合物或配方可含有下列液晶材料：1-(反式-4-己基環己基)-4-異氰硫基苯液晶、苯甲酸化合物(包括4-辛基苯甲酸和4-己基苯甲酸)、碳化腈化合物(包括4'-戊基-4-聯苯基碳化腈、4'-辛基-4-聯苯基碳化腈、4'-(辛氧基)-4-聯苯基碳化腈、4'-(己氧基)-4-聯苯基碳化腈、4-(反式-4-戊基環己基)苯甲腈、4'-(戊 氧基)-4-聯苯基碳化腈、4'-己基-4-聯苯基碳化腈)、和4,4'-氧偶氮苯甲醚。 In a non-limiting sense, the mixture or formulation may contain the following liquid crystal materials: 1-(trans-4-hexylcyclohexyl)-4-isocyanatophenyl liquid crystal, benzoic acid compounds (including 4-octylbenzoic acid and 4-hexylbenzoic acid), carbonized nitrile compound (including 4'-pentyl-4-biphenylcarbonitrile, 4'-octyl-4-biphenylcarbonitrile, 4'-(octyloxy)-4 -biphenylcarbonitrile, 4'-(hexyloxy)-4-biphenylcarbonitrile, 4-(trans-4-pentylcyclohexyl)benzonitrile, 4'-(penta Oxy)-4-biphenylcarbonitrile, 4'-hexyl-4-biphenylcarbonitrile, and 4,4'-oxyazoanisole.

以非限制性的意義，在室溫表現出npar-nperp>0.3的特別高雙折射的配方可以用作形成液晶層的材料。例如，此種配方(被稱作W1825)可得自AWAT和BEAM Engineering for Advanced Measurements Co.(BEAMCO)。 In a non-limiting sense, a formulation having a particularly high birefringence of n par -n perp >0.3 at room temperature can be used as the material for forming the liquid crystal layer. For example, such a formulation (referred to as W1825) is available from AWAT and BEAM Engineering for Advanced Measurements Co. (BEAMCO).

可存在可用於此處發明概念的其他類別的液晶材料。例如，鐵電液晶可提供用於電場定向液晶實施例的功能，但也可引入其他效應諸如磁場相互作用。電磁輻射與材料的相互作用也可不同。 There may be other classes of liquid crystal materials that can be used in the concepts herein. For example, ferroelectric liquid crystals can provide the functionality for electric field directed liquid crystal embodiments, but other effects such as magnetic field interactions can also be introduced. The interaction of electromagnetic radiation with materials can also vary.

配向層材料 Alignment layer material

在已描述的許多實例中，眼用鏡片內的液晶層可需要在插件邊界處以各種方式配向。例如，該配向可平行或垂直於插件的邊界且可藉由各種表面的適當處理來獲得。該處理可涉及在包含液晶(LC)的插件的基材上塗布配向層。該等配向層在本文中有所描述。 In many of the examples that have been described, the liquid crystal layer within the ophthalmic lens may need to be aligned in various ways at the border of the insert. For example, the alignment can be parallel or perpendicular to the boundaries of the insert and can be obtained by appropriate processing of the various surfaces. This treatment may involve coating an alignment layer on a substrate comprising a liquid crystal (LC) insert. These alignment layers are described herein.

在各種類型的液晶型裝置中常實施的技術可為磨刷(rubbing)技術。這些技術可經調適於針對彎曲表面，諸如用於封裝液晶的插件部的彎曲表面。在一實例中，可在表面上塗布聚乙烯醇(PVA)層。例如，可使用1重量%水溶液旋塗(spin coat)PVA層。可以1000rpm旋塗一定時間諸如大約60s來施加溶液，然後乾燥。隨後，可以用軟布磨刷經乾燥的層。在非限制性實例中，該軟布可為絲絨。 A technique that is often implemented in various types of liquid crystal type devices may be a rubbing technique. These techniques can be adapted to be directed to curved surfaces, such as curved surfaces for encapsulating portions of liquid crystals. In one example, a layer of polyvinyl alcohol (PVA) can be applied to the surface. For example, a 1 wt% aqueous solution can be used to spin coat the PVA layer. The solution can be applied by spin coating at 1000 rpm for a certain time, such as about 60 s, and then dried. The dried layer can then be brushed with a soft cloth. In a non-limiting example, the soft cloth can be velvet.

光配向可為用於在液晶封裝件上產生配向層的另一種技術。在一些實例中，由於其非接觸之性質和大量製造的生產量，光配向可為需要的。在非限制性實例中，在液晶可變光學部分中使用的光配向層可由二向色偶氮苯染料(偶氮染料)構成，而該染料能夠主要在垂直於通常為紫外線波長的線性偏振光的偏振方向上配向。此類配向可以是反覆的反式-順式-反式光異構化過程的結果。 Light alignment can be another technique for creating an alignment layer on a liquid crystal package. In some instances, photoalignment may be desirable due to its non-contact nature and mass production throughput. In a non-limiting example, the photoalignment layer used in the liquid crystal variable optics portion can be composed of a dichrochromatic azobenzene dye (azo dye) that is capable of predominantly linearly polarized light perpendicular to the generally ultraviolet wavelength. Orientation in the direction of polarization. Such alignment can be the result of a repeated trans-cis-trans photoisomerization process.

舉例來說，可自1重量%之二甲基甲醯胺(DMF)溶液在3000rpm轉速下旋塗PAAD系列偶氮苯染料30s。隨後，可將所獲得的層暴露於紫外線波長(例如325nm、351nm、365nm)或甚至可見波長(400-500nm)的線性偏振光束。光源可採取各種形式。在一些實施例中，光可源自例如雷射源。其他光源諸如LED、鹵素燈或白熾燈光源可為其他非限制性實例。在適當時，在各種形式的光以各種圖案偏振之前或之後，光可以各種方式準直，諸如透過使用光學透鏡裝置來準直。例如，來自雷射源的光可固有地具有一定程度的準直。 For example, the PAAD series azobenzene dye can be spin coated from a 1% by weight solution of dimethylformamide (DMF) at 3000 rpm for 30 s. The resulting layer can then be exposed to a linearly polarized beam of ultraviolet wavelength (eg, 325 nm, 351 nm, 365 nm) or even visible wavelength (400-500 nm). The light source can take a variety of forms. In some embodiments, the light may be derived, for example, from a laser source. Other light sources such as LEDs, halogen lamps or incandescent light sources can be other non-limiting examples. Where appropriate, the light can be collimated in various ways before or after the various forms of light are polarized in various patterns, such as by collimating using an optical lens device. For example, light from a laser source can inherently have a degree of collimation.

目前已知多種基於偶氮苯聚合物、聚酯、具有介晶4-(4-甲氧基桂皮醯基氧基)聯苯側基的光可交聯的聚合物液晶等之光各向異性材料。此類材料的實例包括磺基雙偶氮染料SD1和其他偶氮苯染料(具體地，可得自BEAM Engineering for Advanced Measurements Co.(BEAMCO)的PAAD系列材料)、聚(乙烯基桂皮酸酯)、以及其他材料。 Various optical anisotropy of photocrosslinkable polymer liquid crystals based on azobenzene polymers, polyesters, and pendant 4-(4-methoxycinnaminooxy)biphenyl groups are known. material. Examples of such materials include sulfobisazo dye SD1 and other azobenzene dyes (specifically, PAAD series materials available from BEAM Engineering for Advanced Measurements Co. (BEAMCO)), poly(vinyl cinnamate) And other materials.

在一些實例中，可期望使用PAAD系列偶氮染料的水或醇溶液。一些偶氮苯染料，例如甲基紅，可用於藉由直接摻雜液晶層來進行光配向。偶氮苯染料暴露於偏振光可造成偶氮染料擴散 和附著到液晶層至邊界層的大部分之上和之內，因而形成所需的配向條件。 In some instances, it may be desirable to use a water or alcohol solution of the PAAD series of azo dyes. Some azobenzene dyes, such as methyl red, can be used for photoalignment by directly doping the liquid crystal layer. Exposure of polarized light to azobenzene dyes can cause azo dye diffusion And attaching to and over most of the liquid crystal layer to the boundary layer, thus forming the desired alignment conditions.

偶氮苯染料諸如甲基紅也可與聚合物例如PVA組合使用。目前已知可接受能夠增強相鄰液晶層配向的其他光各向異性材料。這些實例可包括基於如下的材料：香豆素、聚酯、具有介晶4-(4-甲氧基桂皮醯基氧基)-聯苯側基的可光交聯的聚合物液晶、聚(乙烯基桂皮酸酯)等等。光配向技術對於包含液晶的圖案化定向的實施例可能是有利的。 An azobenzene dye such as methyl red can also be used in combination with a polymer such as PVA. Other optically anisotropic materials that are capable of enhancing the alignment of adjacent liquid crystal layers are currently known to be acceptable. These examples may include materials based on coumarin, polyester, photocrosslinkable polymer liquid crystals having mesogenic 4-(4-methoxycincosyloxy)-biphenyl pendant groups, poly( Vinyl cinnamate) and so on. Light alignment techniques may be advantageous for embodiments that include patterned orientation of liquid crystals.

在製作配向層的另一個實例中，可藉由在插件基材上真空沉積氧化矽(SiOx，其中1<=X<=2)來獲得配向層。例如，可以在低壓諸如約10-6毫巴下沉積SiO2。可在形成前和後插件部時以奈米級尺寸提供經射出成形的配向特徵。可用已提及的材料或可與物理配向特徵直接相互作用並將配向圖案傳輸到液晶分子的配向定向中的其他材料，以各種方式塗布這些模塑的特徵。 In another example of fabricating the alignment layer, the alignment layer can be obtained by vacuum deposition of yttrium oxide (SiOx, where 1 <= X <= 2) on the insert substrate. For example, SiO 2 can be deposited at a low pressure, such as about 10-6 mbar. The injection-formed alignment features can be provided in nanometer dimensions when forming the front and rear insert portions. These molded features can be applied in a variety of ways using the materials already mentioned or other materials that can directly interact with the physical alignment features and transport the alignment pattern into the alignment orientation of the liquid crystal molecules.

離子束配向可以是用於在液晶外殼上產生配向層的另一種技術。在一些實例中，可以以確定的角度/定向在配向層上轟擊準直的氬或聚焦的鎵離子束。這類配向也可以用於配向氧化矽、金剛石樣碳(DLC)、聚醯亞胺和其它配向材料。 Ion beam alignment can be another technique for creating an alignment layer on a liquid crystal housing. In some examples, the collimated argon or focused gallium ion beam can be bombarded on the alignment layer at a determined angle/orientation. Such alignments can also be used for the distribution of yttrium oxide, diamond-like carbon (DLC), polyimine and other alignment materials.

另外的實例可有關於插件部形成之後對其製作物理配向之特徵。可在經模塑表面上執行如其他液晶式技術中常用的摩刷技術以形成物理溝槽。也可對表面進行後模塑壓印程序以在其上形成小溝槽狀特徵。另外的實施例可源自蝕刻技術的使用，所述蝕刻技術可涉及各種類型的光學圖案化程序。 Further examples may be characterized as to the physical alignment of the insert portion after it has been formed. A brushing technique such as that commonly used in other liquid crystal technologies can be performed on a molded surface to form a physical groove. The surface may also be post-molded with an embossing procedure to form small groove-like features thereon. Further embodiments may be derived from the use of etching techniques that may involve various types of optical patterning procedures.

A defect may be referred to as a pinhole, as is known to those of ordinary skill in the art, as a hole in the dielectric that allows electrical and/or chemical contact through the dielectric. A dielectric of a given thickness can meet the breakdown voltage requirements, for example, the dielectric should withstand 100 volts or more.

介電質可允許製造於彎曲、錐形、球形和複雜三維表面(如，彎曲表面或非平面表面)上。可使用浸塗和旋塗的一般方法，或可採用其他方法。 Dielectrics can be fabricated on curved, tapered, spherical, and complex three-dimensional surfaces (eg, curved or non-planar surfaces). A general method of dip coating and spin coating may be used, or other methods may be employed.

The dielectric is resistant to damage from infrared, ultraviolet and visible light. Undesired damage can include degradation of the parameters (e.g., breakdown voltage and optical transmission rate) described herein. The dielectric is resistant to ion penetration. The dielectric prevents electron migration, dendrite growth, and other degradation of the underlying electrode. The dielectric can be adhered to the underlying electrode and/or substrate by, for example, using an adhesion promoting layer. The dielectric can be made using a method that achieves low contamination, low surface defects, conformal coating, and low surface roughness.

介電質可具有與系統的電操作相配的相對電容率或介電常數，例如，低相對電容率以降低給定電極區域的電容。介電質可具有高電阻率，從而即使施加高電壓，也只允許非常少的電流 流動。介電質可具有光學裝置所需的性質，例如，高傳輸率、低分散性、和一定範圍內的折射率。 The dielectric can have a relative permittivity or dielectric constant that matches the electrical operation of the system, for example, a low relative permittivity to reduce the capacitance of a given electrode region. The dielectric can have a high resistivity, allowing very little current even when a high voltage is applied flow. The dielectric can have properties required for optical devices, such as high transmission rates, low dispersion, and a range of refractive indices.

In addition, not all steps are required to implement the disclosure, and additional steps may be included in the various exemplary embodiments disclosed herein. It will be apparent to those skilled in the art that additional exemplary embodiments can be implemented, and such methods are well within the scope of the patent application.

請參照圖7，流程圖繪示可用於實施本揭露的例示性步驟。在701，形成可以包含後曲面表面且具有頂表面的第一基材層，該頂表面具有可不同於其它基材層的表面形狀的第一種形狀。在一些實例中，該差異可以包括至少在可安設在光學區中的一部分中的表面的不同曲率半徑。在702，形成可以包含前曲面表面或中間表面或中間表面的部分(對於更複雜的裝置)的第二基材層。在703，可將一電極層沉積在第一基材層上。該沉積可例如藉由氣相沉積或電鍍進行。在一些實施例中，第一基材層可為同時具有光學區中的區域和非光學區中的區域的一插件的一部分。在一些例示性實施例中，電極沉積程序可同時界定各個互連特徵。在一些實例中，介電層可以形成在互連或電極上。介電層可包含許多絕緣層和介電層，例如二氧化矽。 Referring to Figure 7, a flowchart illustrates exemplary steps that may be used to implement the present disclosure. At 701, a first substrate layer is formed that can include a back curve surface and has a top surface having a first shape that can be different from the surface shape of the other substrate layer. In some examples, the difference can include at least a different radius of curvature of the surface in a portion that can be mounted in the optical zone. At 702, a second substrate layer is formed that can include a front curve surface or an intermediate surface or intermediate surface portion (for more complex devices). At 703, an electrode layer can be deposited on the first substrate layer. This deposition can be carried out, for example, by vapor deposition or electroplating. In some embodiments, the first substrate layer can be part of an insert that has both a region in the optical zone and a region in the non-optical zone. In some exemplary embodiments, the electrode deposition process can define individual interconnect features simultaneously. In some examples, a dielectric layer can be formed over the interconnect or electrode. The dielectric layer can comprise a plurality of insulating layers and a dielectric layer, such as hafnium oxide.

在704處，可進一步處理第一基材層以將一配向層添加在先前沉積的介電層或電極層之上。可將配向層沉積在基材上的頂層之上，然後以標準方式例如摩刷技術處理以形成標準配向層特 有的溝槽特徵，或者藉由暴露於高能粒子或光進行處理。光各向異性材料的薄層可用光暴露進行處理以形成具有各種特性的配向層。如前所述，在形成液晶層(在其中形成經間隙定位之網狀聚合物區域)的方法中，該方法可不包括與配向層的形成有關的步驟。 At 704, the first substrate layer can be further processed to add an alignment layer over the previously deposited dielectric layer or electrode layer. The alignment layer can be deposited on top of the substrate and then processed in a standard manner such as a brushing technique to form a standard alignment layer. Some trench features are treated by exposure to energetic particles or light. A thin layer of an optically anisotropic material can be treated with light exposure to form an alignment layer having various characteristics. As described above, in the method of forming a liquid crystal layer in which a gap-located network polymer region is formed, the method may not include a step related to formation of an alignment layer.

在705處，可進一步處理第二基材層。可按照與步驟703類似的方式將電極層沉積在第二基材層之上。之後在一些實例中，在706處，可將介電層施加在第二基材層上面的電極層之上。介電層可形成為橫跨其表面具有可變厚度。舉例來說，介電層可模塑在第一基材層之上。或者，先前形成的介電層可黏附在第二基材件的電極表面之上。 At 705, the second substrate layer can be further processed. An electrode layer can be deposited over the second substrate layer in a manner similar to step 703. Thereafter, in some examples, at 706, a dielectric layer can be applied over the electrode layer above the second substrate layer.

Alternatively, the previously formed dielectric layer can be adhered over the electrode surface of the second substrate member.

在707，可按照與704處的處理步驟類似的方式在第二基材層之上形成配向層。在707之後，可形成眼用鏡片插件的至少一部分的兩個分離的基材層可以隨時接合。在一些實例中，在708，可使這兩個件彼此靠近，然後在這兩個件之間填充液晶材料。可存在許多將液晶填充在該等件之間的方式，包括(作為非限制性實例)基於真空的填充，其中可以將腔穴抽真空，隨後允許液晶材料流入抽真空的空間中。此外，存在於鏡片插件之間的空間中的毛細管力可以輔助用液晶材料填充該空間。在709處，可使這兩個件彼此相鄰，然後密封形成具有液晶的可變光學元件。可以存在許多將該等件密封在一起的方式，其中包括使用粘著劑、密封劑和物理密封組件諸如(作為非限制性實例)O型環以及搭扣鎖(snap lock)特徵。 At 707, an alignment layer can be formed over the second substrate layer in a manner similar to the processing steps at 704. After 707, two separate substrate layers that can form at least a portion of the ophthalmic lens insert can be joined at any time. In some examples, at 708, the two pieces can be brought close to each other and then the liquid crystal material is filled between the two pieces. There may be many ways to fill the liquid crystal between the pieces, including (as a non-limiting example) a vacuum based fill in which the cavity may be evacuated, followed by allowing the liquid crystal material to flow into the evacuated space. In addition, capillary forces present in the space between the lens inserts can assist in filling the space with liquid crystal material. At 709, the two pieces can be brought adjacent to each other and then sealed to form a variable optical element having liquid crystal. There may be many ways in which the pieces are sealed together, including the use of adhesives, sealants, and physical seal components such as, by way of non-limiting example, O-rings and snap lock features.

An energy source and one or more components can also be attached to the substrate and can be in electrical communication with the variable optical insert. The assembly can include, for example, circuitry for controlling power applied to the variable optical insert. Thus, in some examples, the assembly includes a control mechanism for actuating the variable optical insert, thereby changing one or more optical characteristics, such as a change in state between the first optical power and the second optical power.

在一些實例中，處理器裝置、微機電系統(MEMS)、奈米機電系統(NEMS)或其他組件也可放置於可變光學插件中並與能量源電接觸。在712，可將反應性單體混合物沉積在模具零件中。在713，可將可變光學插件定位成與反應性混合物接觸。在一些實例中，可顛倒可變光學元件的放置和單體混合物的沉積的順序。在714處，將第一模具零件鄰近第二模具零件放置以形成鏡片成形腔穴，其中至少一些反應性單體混合物和可變光學插件在腔穴中。如 上文所討論，較佳實施例包括也位於腔穴內並與可變光學插件電連通的一能量源和一或多個組件。 In some examples, a processor device, a microelectromechanical system (MEMS), a nanoelectromechanical system (NEMS), or other components can also be placed in the variable optical card and in electrical contact with the energy source. At 712, a reactive monomer mixture can be deposited in the mold part. At 713, the variable optical insert can be positioned in contact with the reactive mixture. In some examples, the placement of the variable optical elements and the order of deposition of the monomer mixture can be reversed. At 714, the first mold part is placed adjacent to the second mold part to form a lens forming cavity, wherein at least some of the reactive monomer mixture and the variable optical insert are in the cavity. Such as As discussed above, the preferred embodiment includes an energy source and one or more components that are also located within the cavity and in electrical communication with the variable optical insert.

在715處，使腔穴內的反應性單體混合物聚合。例如可透過暴露於光化輻射和熱中的一者或二者來實現聚合反應。在716處，從模具零件中取出眼用鏡片，其中可變光學插件黏附於或封裝在組成眼用鏡片的插件封裝聚合材料內。 At 715, the reactive monomer mixture within the cavity is polymerized. The polymerization can be achieved, for example, by exposure to one or both of actinic radiation and heat. At 716, the ophthalmic lens is removed from the mold part, wherein the variable optical insert is adhered or encapsulated within the insert encapsulating polymeric material that makes up the ophthalmic lens.

包括梯度折射率液晶元件及介電層的可變光學插件 Variable optical insert including gradient index liquid crystal element and dielectric layer

請參照圖10A，圖中繪示了具有液晶層1025且可***眼用鏡片中的可變光學部分1000。可變光學部分1000可具有如已在本說明書的其他段落中所討論的類似的材料多樣性和結構關聯性。在一些例示性實施例中，第一透明電極1050可放置於第一透明基材1055上。第一鏡片件可以包括介電層1040。該層可由介電膜構成，且在一些實例中，可將配向層放在介電層1040上。在其它實例中，可以使配向層具有雙重功能的方式形成介電層。在包含介電層的實例中，第一鏡片表面的介電層1040的形狀可在所示的介電厚度中形成一區域性變化的形狀。這樣的隨區域變化的形狀可以在彎曲層的幾何效應上面引入鏡片元件的額外聚焦能力。在一些實例中，例如，成形的介電層可透過在第一透明電極1050第一透明基材1055組合上面射出成形而形成。 Referring to Figure 10A, a variable optical portion 1000 having a liquid crystal layer 1025 and insertable into an ophthalmic lens is illustrated. Variable optical portion 1000 can have similar material variability and structural relevance as discussed in other paragraphs of this specification. In some exemplary embodiments, the first transparent electrode 1050 can be placed on the first transparent substrate 1055. The first lens member can include a dielectric layer 1040. This layer may be composed of a dielectric film, and in some examples, an alignment layer may be placed over the dielectric layer 1040. In other examples, the dielectric layer can be formed in a dual function. In an example comprising a dielectric layer, the shape of the dielectric layer 1040 of the first lens surface can form a regionally varying shape in the dielectric thickness shown. Such a change in shape with the region can introduce additional focusing capabilities of the lens elements above the geometric effects of the curved layer. In some examples, for example, the shaped dielectric layer can be formed by injection molding over the first transparent substrate 1050 first transparent substrate 1055 combination.

在一些實例中，第一透明電極1050和第二透明電極1015可以各種方式成形。在一些實例中，成形可導致形成分離的獨立區域，因而可分別施加賦能。在其他實例中，電極可形成為諸如從鏡片中心到周邊的螺旋之圖案，從而可橫跨液晶層1025施加可變電場。在任一種情況下，除了電極上的介電層的成形之外或者作為 此類成形的替代，可進行此類電極之成形。電極以這些方式的成形也可引入操作狀態下的鏡片元件的額外聚焦能力。 In some examples, first transparent electrode 1050 and second transparent electrode 1015 can be formed in a variety of ways. In some instances, shaping can result in the formation of separate, separate regions, and thus energization can be applied separately. In other examples, the electrodes can be formed into a pattern such as a spiral from the center of the lens to the periphery such that a variable electric field can be applied across the liquid crystal layer 1025. In either case, in addition to or as a form of the dielectric layer on the electrode An alternative to such forming is the formation of such electrodes. The shaping of the electrodes in these manners can also introduce additional focusing capabilities of the lens elements in the operational state.

液晶層1025可位於第一透明電極1050與第二透明電極1015之間。第二透明電極1015可附接至第二透明基材層1010，其中從第二透明基材層1010至第一透明基材1055形成的裝置可以含有眼用鏡片的可變光學部分。兩個配向層也可位於介電層上的1020和1030處並且可圍繞液晶層1025。1020和1030處的配向層可作用以界定眼用鏡片的靜止定向。在一些實例中，電極層可與液晶層1025電連通，並導致定向從靜止定向轉變為至少一種經賦能定向。 The liquid crystal layer 1025 may be located between the first transparent electrode 1050 and the second transparent electrode 1015. The second transparent electrode 1015 can be attached to the second transparent substrate layer 1010, wherein the device formed from the second transparent substrate layer 1010 to the first transparent substrate 1055 can contain a variable optical portion of the ophthalmic lens. Two alignment layers can also be located at 1020 and 1030 on the dielectric layer and can surround the liquid crystal layer 1025. The alignment layers at 1020 and 1030 can act to define the static orientation of the ophthalmic lens. In some examples, the electrode layer can be in electrical communication with the liquid crystal layer 1025 and cause the orientation to transition from a stationary orientation to at least one energized orientation.

參照圖10B，圖中繪示具有一梯度折射率液晶層1075且可***眼用鏡片中的可變光學部分1056之一替代例。與圖10A中的可變光學部分1000類似，在插件內可存在成形介電層。例如，包括1085、1090和1095在內的層可以在例示性的第一鏡片件1097上形成複合成形之介電層。介電層的電效應可使當賦能插件時施加於液晶層1075上的有效電場成形。第一透明電極1096可以位於第一基材層或鏡片件1097上，且第二透明電極1065可以位於第二基材層上(其已被稱為第二基材層1060)。在一些實例中，配向層也可以位於液晶層1075周圍，並影響其中分子的配向。 Referring to Figure 10B, an alternative to one of the variable optical portions 1056 having a gradient index liquid crystal layer 1075 and insertable into an ophthalmic lens is illustrated. Similar to the variable optic portion 1000 of Figure 10A, a shaped dielectric layer can be present within the insert. For example, layers including 1085, 1090, and 1095 can form a composite shaped dielectric layer on the exemplary first lens member 1097. The electrical effect of the dielectric layer allows for the formation of an effective electric field applied to the liquid crystal layer 1075 when the insert is energized. The first transparent electrode 1096 can be on the first substrate layer or lens member 1097, and the second transparent electrode 1065 can be on the second substrate layer (which has been referred to as the second substrate layer 1060). In some examples, the alignment layer can also be located around the liquid crystal layer 1075 and affect the alignment of the molecules therein.

插件(其也可以被稱作可變光學部分1056)可繪示成具有多個在1085、1090和1095處之介電層。在一些實施例中，中間介電層1085和中間介電層1095可由一種介電材料構成，而層1090可由一不同類型的材料構成。在一些實例中，如此相對複雜的結構可以實現在不同頻率具有不同有效介電強度的介電質材料的組 合。例如，中間介電層1085和1095可由(以非限制性之意)二氧化矽構成，而在層1090處的材料可以是水溶液。在光頻率下，可以以使得對光束的效應在所有層中類似的方式形成這些層。然而，在如可以施加於電極1065和1096的較低電頻率下，一水性形式之層1090可以具有不同於其它層的介電性質，因而實現對於可在液晶層1075上運行之電場的區域性成形之增強效應。 The insert (which may also be referred to as variable optic portion 1056) may be illustrated as having a plurality of dielectric layers at 1085, 1090, and 1095. In some embodiments, the intermediate dielectric layer 1085 and the intermediate dielectric layer 1095 can be comprised of a dielectric material, while the layer 1090 can be constructed of a different type of material. In some instances, such a relatively complex structure can achieve a group of dielectric materials having different effective dielectric strengths at different frequencies. Hehe. For example, the intermediate dielectric layers 1085 and 1095 can be comprised of, by way of non-limiting, cerium oxide, while the material at layer 1090 can be an aqueous solution. At the optical frequency, these layers can be formed in a manner such that the effect on the beam is similar in all layers.
