Description

處方用鏡片結構 Prescription lens structure

本創作係關於一種鏡片結構，尤指一種處方用鏡片結構者。 This creation is about a lens structure, especially a prescription lens structure.

按，一般在製作平光太陽眼鏡鏡片的材料時，主要會先將聚醯胺(polyamide,PA)或聚碳酸酯(polycarbonate,PC)等材料與染料預先混合抽料造粒後，再以射出或澆注成型方式製作出厚薄約略均一且具有濾光能力的平光太陽眼鏡鏡片。 In general, when making flat-light sunglasses lens materials, materials such as polyamide (PA) or polycarbonate (PC) and dyes are first mixed and pumped into granules before injection or injection. The casting method is used to produce flat-light sunglasses lenses with approximately uniform thickness and filtering ability.

呈上所述，由於鏡片曲率的關係造成鏡片中心與鏡片邊緣的厚薄差異較大，因此，若是以相同的方式來製作處方用濾光鏡片，則會導致鏡片中心與鏡片邊緣的濾光效能不同，且鏡片的顏色也會深淺不一，進而造成配戴者觀看景物時的視覺感受不佳。 As mentioned above, due to the curvature of the lens, the thickness of the lens center and the edge of the lens have a large difference. Therefore, if the prescription filter lens is made in the same way, the filtering efficiency of the lens center and the edge of the lens will be different , And the color of the lens will be different, which causes the wearer's visual perception when viewing the scene is poor.

再者，目前在製作處方太陽眼鏡鏡片的程序大多是將鏡片毛胚加工成處方鏡片之後，再以浸泡或噴塗方式在鏡片表面進行染色程序，因此這樣的製造方法使鏡片染色的效果較不均勻，並且在戶外長期使用的耐候性也較差。因此，如何提供一種較佳的處方用鏡片結構，實為當前重要課題之一。 In addition, most of the current procedures for making prescription sunglasses lenses are to process the lens blank into prescription lenses, and then immerse or spray on the lens surface to perform the dyeing procedure. Therefore, this manufacturing method makes the lens dyeing effect uneven. And the weather resistance for long-term outdoor use is also poor. So how to provide a A better prescription lens structure is really one of the important issues at present.

In addition, if this creative setting includes polarized lenses, a polarizing layer (not shown) can also be added together during the first molding to make it mold.

接著，再將該第一鏡片(1)放入該第二鏡片(2)的模具中，以聚醯胺材料或聚碳酸酯材料或聚胺酯(Polyurethane,PU)，將該第二鏡片(2)直接成型於該第一鏡片(1)的一側，使得該第二鏡片 (2)的第二外表面(21)結合於該第一鏡片(1)的第一內表面(12)，進而成為一處方用太陽眼鏡鏡片毛坯，而該第二鏡片(2)之厚度介於5mm~15mm之間。 Next, the first lens (1) is placed in a mold of the second lens (2), and the second lens (2) is made of a polyamide material, a polycarbonate material, or a polyurethane (Polyurethane, PU). Directly formed on one side of the first lens (1), so that the second lens (2) The second outer surface (21) is combined with the first inner surface (12) of the first lens (1), and then becomes a prescription sunglasses lens blank, and the thickness of the second lens (2) is Between 5mm ~ 15mm.

於此，本創作不限制該第一鏡片(1)與該第二鏡片(2)的成型順序，其亦可第一次成型出該第二鏡片(2)，再將該第二鏡片(2)放入該第一鏡片(1)的模具中，並將該第一鏡片(1)成型於該第二鏡片(2)的一側，使得該第一鏡片(1)的第一內表面(12)結合於該第二鏡片(2)的第二外表面(21)，進而成為一處方用太陽眼鏡鏡片毛坯，並如圖1所示，後續再以加工方式於該第二內表面(22)形成一屈光矯正區(3)，而該加工方式可為車削或研磨其中之一或其中組合，進而形成具有預定顏色之屈光矯正的處方用鏡片成品(10)，該處方用鏡片成品(10)之總厚度(t1)則介於0.5mm至17mm之間；又，本創作不限制該第一鏡片(1)及該第二鏡片(2)成型方式，其可藉由澆注、射出或押出方法完成。 Here, this creation does not limit the molding order of the first lens (1) and the second lens (2), it can also form the second lens (2) for the first time, and then the second lens (2) ) Into the mold of the first lens (1), and molding the first lens (1) on one side of the second lens (2), so that the first inner surface of the first lens (1) ( 12) Combined with the second outer surface (21) of the second lens (2), and then become a prescription sunglasses lens blank, as shown in FIG. 1, and subsequently processed on the second inner surface (22) ) Forming a refractive correction area (3), and the processing method may be turning or grinding one or a combination thereof to form a finished prescription lens product (10) with a predetermined color, and the prescription lens product is finished. The total thickness (t1) of (10) is between 0.5mm and 17mm; in addition, the creation of the first lens (1) and the second lens (2) is not restricted, and it can be cast or shot Or the betting method is complete.

再者，該屈光矯正區(3)包含球度數、散光度數及稜鏡度數其中之一或其中組合，而該球度數範圍於+8.00D~-12.00D之間，意即遠視800度~近視1200度的範圍之間；而本創作處方用鏡片成品(10)可為單光矯正度數或雙光矯正度數或多焦點漸近之矯正度數，進而克服先前技術於處方太陽眼鏡鏡片上的問題。 Furthermore, the refractive correction zone (3) includes one or a combination of sphericity, astigmatism, and chirp.

綜上所述，本創作之處方用鏡片結構可有效地解決先前技術所產生的問題，如圖1所示，錐形桿為加工頭(A)示意，在製作有度數的鏡片時，只需依使用者所須度數而對該第二鏡片(2) 進行加工研磨，而該第一鏡片(1)的厚度(t1)仍然保持一致且顏色也為均勻的鏡片。因此，第一鏡片不會有顏色不均的問題，故，當本創作設置於鏡框上，使用者在使用時不會產生色差問題。 In summary, the lens structure used in this creation can effectively solve the problems caused by the previous technology. As shown in Figure 1, the tapered rod is the processing head (A). When making lenses with power, you only need to The second lens according to the power required by the user (2) The lens is processed and polished, and the thickness (t1) of the first lens (1) is still consistent and the color is uniform. Therefore, the first lens does not have the problem of color unevenness. Therefore, when the original creation is set on the lens frame, the user does not have the problem of chromatic aberration when using it.
