圖2係表示眼鏡鏡片之各部之概念圖。計算裝置200計算關於眼鏡鏡片LS之光學特性之資訊。於圖2之例中，眼鏡鏡片LS係中近兩用漸進折射力鏡片。眼鏡鏡片LS成為配合眼鏡用鏡架之形狀加工鏡片前之狀態（鏡片打磨加工前之狀態），於俯視下形成為圓形。眼鏡鏡片LS係圖中上側於配戴時配置於上方，圖中下側於配戴時配置於下方。眼鏡鏡片LS具有遠用部F、近用部N及中間部P。Figure 2 is a conceptual diagram showing the various parts of the spectacle lens. The calculation device 200 calculates information about the optical characteristics of the spectacle lens LS. In the example shown in Figure 2, the spectacle lens LS is a progressive refractive lens for mid-near dual purpose. The spectacle lens LS is in the state before the lens is processed according to the shape of the spectacle frame (the state before the lens is polished), and is formed into a circle in a plan view. The upper side of the spectacle lens LS in the figure is arranged above when worn, and the lower side in the figure is arranged below when worn. The spectacle lens LS has a far part F, a near part N, and a middle part P.

遠用部F配置於眼鏡鏡片LS之上部，近用部N配置於眼鏡鏡片LS之下部。將眼鏡鏡片LS加工成眼鏡用途之後，遠用部F成為與近用部N相比具有與更長之距離對應之折射力之部分。換言之，遠用部F係用以觀看處於較與通過近用部N觀看之對象相距之距離更長之距離之對象的部分。中間部P配置於眼鏡鏡片LS中遠用部F與近用部N之中間，遠用部F與近用部N之間之折射力適當連續地順暢地變化而連接。The far part F is arranged on the upper part of the eyeglass lens LS, and the near part N is arranged on the lower part of the eyeglass lens LS. After processing the spectacle lens LS into spectacle use, the far part F becomes a part having a refractive power corresponding to a longer distance than the near part N. In other words, the far part F is a part for viewing an object at a longer distance than the object viewed through the near part N. The intermediate portion P is arranged between the far portion F and the near portion N of the eyeglass lens LS, and the refractive power between the far portion F and the near portion N is appropriately continuously and smoothly changed and connected.

眼鏡鏡片LS具有複數個基準點。作為此種基準點，例如，如圖2所示，可列舉眼點（亦稱為契合點）EP、遠用參考點FV、近用參考點NV。眼點EP成為配戴者配戴眼鏡鏡片LS時之瞳孔之位置之基準點。於以下之實施形態中，設為眼點EP位於中間部P。遠用參考點FV成為測定鏡片之遠用度數之測定基準點。近用參考點NV成為測定鏡片之近用度數之測定基準點。再者，遠用部F係包含遠用參考點FV之區域，可具有折射力大致固定之區域，亦可不具有折射力大致固定之區域。又，近用部N係包含近用參考點NV之區域，可具有折射力大致固定之區域，亦可不具有折射力大致固定之區域。The spectacle lens LS has a plurality of reference points. As such a reference point, as shown in FIG. 2, for example, an eye point (also referred to as an engagement point) EP, a far reference point FV, and a near reference point NV can be cited. The eye point EP becomes the reference point of the pupil position when the wearer wears the spectacle lens LS. In the following embodiments, it is assumed that the eye point EP is located in the middle portion P. The distance reference point FV becomes the measurement reference point for measuring the distance power of the lens. The near reference point NV becomes the measurement reference point for determining the near power of the lens. Furthermore, the far-use portion F is a region including the far-use reference point FV, and may have a region where the refractive power is approximately constant, or may not have a region where the refractive power is approximately constant. In addition, the near portion N is an area including the near reference point NV, and may have an area where the refractive power is approximately constant, or may not have an area where the refractive power is approximately constant.

於眼鏡鏡片LS之大致中央，設置有配戴者自正面上方觀看位於正面下方之物體之情形時視線通過之鏡片上之假想線即主注視線M。主注視線M亦稱為主子午線。主注視線M係於遠用部F中通過遠用參考點FV與眼點EP，且沿著配戴時之與鉛垂方向對應之方向（以下，稱為「高度方向」）設定。主注視線M係於近用部N中通過近用參考點NV，且沿著高度方向設定。近用參考點NV係考慮會聚而朝鼻子側（圖2中為右側）向內靠近。主注視線M之一部分係於中間部P將遠用參考點FV與近用參考點NV連接，因此，相對於高度方向傾斜地設定。At the approximate center of the spectacle lens LS, there is an imaginary line on the lens through which the wearer's line of sight passes when the wearer views an object below the front face, that is, the main gaze line M. The main line of gaze M is also called the main meridian. The main gaze line M passes through the distance reference point FV and the eye point EP in the distance portion F, and is set along the direction corresponding to the vertical direction at the time of wearing (hereinafter referred to as the "height direction"). The main gaze line M passes through the near reference point NV in the near part N, and is set along the height direction. The near reference point NV is to approach the nose side (the right side in Figure 2) inward in consideration of convergence. A part of the main line of gaze M connects the far reference point FV and the near reference point NV to the middle part P, and therefore is set obliquely with respect to the height direction.

將沿著高度方向之遠用參考點FV與眼點EP之間之距離設為Lf，將沿著高度方向之眼點EP與近用參考點NV之間之距離設為Ln。於以下之實施形態中，將沿著高度方向之遠用參考點FV與近用參考點NV之間之距離（Lf＋Ln）為18 mm以上或眼點EP處之加入度為近用參考點NV處之加入度與遠用參考點FV處之加入度之差（以下，稱為「標稱加入度」）之15%以上的漸進折射力鏡片設為中近兩用漸進折射力鏡片（以下，稱為中近兩用鏡片）。於加入度曲線（參照圖4）中，相較中間部P中之眼點EP之上側之傾斜度而下側之傾斜度更陡之眼鏡鏡片不通用。就此種觀點而言，中近兩用鏡片之眼點EP處之加入度適當設定為標稱加入度之50%以下、40%以下等。又，將上述距離（Lf＋Ln）未達18 mm且眼點EP處之加入度未達標稱加入度之15%的漸進折射力鏡片設為遠近兩用漸進折射力鏡片（以下，稱為遠近兩用鏡片）。Let the distance between the far reference point FV and the eye point EP along the height direction be Lf, and let the distance between the eye point EP and the near reference point NV along the height direction be Ln. In the following embodiment, the distance (Lf+Ln) between the far reference point FV and the near reference point NV along the height direction is 18 mm or more or the addition at the eye point EP is taken as the near reference point NV. The difference between the addition degree and the addition degree at the far reference point FV (hereinafter referred to as the "nominal addition degree") of more than 15% of the progressive refractive power lens is set as the near-medium dual-purpose progressive refractive power lens (hereinafter, referred to as For the near-medium dual purpose lens). In the addition curve (refer to Fig. 4), eyeglass lenses with steeper inclination on the lower side than the upper side of the eye point EP in the middle part P are not universal. From this point of view, the addition degree at the eye point EP of the mid-to-near dual-purpose lens is appropriately set to be below 50%, below 40%, etc. of the nominal addition degree. In addition, a progressive refractive power lens with the above-mentioned distance (Lf+Ln) less than 18 mm and the addition degree at the eye point EP less than 15% of the nominal addition degree is set as a progressive refractive power lens for both near and far use (hereinafter, referred to as both near and far With lenses).

於中近兩用鏡片中，例如以通過遠用部F較佳地觀看遠距離或中間距離之對象物之方式設計，且以通過近用部N較佳地觀看近距離之對象物之方式設計。於遠近兩用鏡片中，例如以通過遠用部F較佳地觀看遠距離之對象物之方式設計，且以通過近用部N較佳地觀看近距離之對象物之方式設計。與遠距離、中間距離及近距離對應之距離亦根據國家、地區或眼鏡鏡片之用途等而變化，並無特別限定，例如遠距離為1 m以上，中間距離為50 cm以上且未達1 m，近距離為25 cm以上且未達50 cm。In the near-medium dual-purpose lens, for example, it is designed to better view objects at a long distance or an intermediate distance through the far-use part F, and designed to better view objects at a short distance through the near-use part N . In the near-distance dual-purpose lens, for example, it is designed to better view objects at a distance through the far portion F, and to better view objects at a short distance through the near portion N. The distance corresponding to the long distance, the middle distance and the short distance also varies according to the country, region, or the use of the glasses lens, and is not particularly limited. For example, the long distance is 1 m or more, and the middle distance is 50 cm or more and less than 1 m. , The close distance is more than 25 cm and less than 50 cm.

Alternatively, the clerk can ask the wearer what kind of object he usually looks at, and consider the distance between the object answered by the wearer and the normal eye and the object when viewing the object as passing through the middle part P or near Input with the viewing distance of part N. As another example, the clerk may ask the wearer how far away the object is to be viewed, and input the distance answered by the wearer as the distance viewed from the middle part P or the near part N. As another example, the wearer can actually arrange the object at a desired position for viewing, measure the distance between the wearer and the object, and use the distance. The method of obtaining the distance seen by the wearer through the middle part P or the near part N is not particularly limited.

計算部300基於配方資料、第1距離及第2距離，計算適合配戴者之眼鏡鏡片LS之光學特性相關之數值。以下，於數式中「×」表示積。Based on the formula data, the first distance and the second distance, the calculation unit 300 calculates numerical values related to the optical characteristics of the spectacle lens LS suitable for the wearer. Hereinafter, "×" in the numerical formula means product.

調節力計算部310根據第1距離及配方加入度，計算配戴者之調節力。調節力計算部310計算第1距離之倒數，並計算觀看第1距離所需之加入度。若將第1距離設為D1（單位為cm），並將觀看第1距離所需之加入度設為A1，則A1根據以下之式（1）求出。 A1＝100/D1…（1）The adjustment power calculation unit 310 calculates the adjustment power of the wearer based on the first distance and the formula addition degree. The accommodation power calculation unit 310 calculates the reciprocal of the first distance, and calculates the degree of addition required for viewing the first distance. If the first distance is set to D1 (in cm), and the degree of addition required to view the first distance is set to A1, then A1 is calculated according to the following formula (1). A1=100/D1...(1)

其次，計算觀看第1距離所需之加入度與配方加入度之差。若將該差設為Di，並將配方加入度設為Addp，則差Di根據以下之式（2）求出。 Di＝A1－Addp…（2） 設想該差Di以由配戴者之調節力之50%補充之方式配方。因此，配戴者之調節力Ac根據以下之式（3）求出。 Ac＝2×Di…（3） 再者，此處，設想差Di以由配戴者之調節力之50%補充之方式配方，但亦可使用40%或60%等適當設定之值。Secondly, calculate the difference between the addition degree required to view the first distance and the formula addition degree. If this difference is set to Di, and the recipe addition degree is set to Addp, the difference Di is calculated according to the following formula (2). Di = A1-Addp... (2) It is assumed that the difference Di is formulated in a way that is supplemented by 50% of the wearer's accommodation. Therefore, the adjustment force Ac of the wearer is obtained according to the following equation (3). Ac=2×Di...(3) Furthermore, here, it is assumed that the difference Di is formulated to be supplemented by 50% of the wearer's accommodative power, but an appropriately set value such as 40% or 60% can also be used.

於根據上述式（1）（2）及（3）計算出之調節力Ac成為負值之情形時，計算部300中斷計算處理。其後，顯示控制部214使顯示部203顯示用以讓使用者知曉產生計算錯誤之內容之畫面。顯示部203例如可將「相對於加入度而言手邊距離過遠」等訊息顯示於該畫面。When the accommodation force Ac calculated according to the above formulas (1), (2) and (3) becomes a negative value, the calculation unit 300 interrupts the calculation process. Thereafter, the display control unit 214 causes the display unit 203 to display a screen for letting the user know the content of the calculation error. For example, the display unit 203 may display a message such as "the distance at hand is too far relative to the degree of joining" on the screen.

調節力計算部310係於根據上述式（1）（2）及（3）計算出之配戴者之調節力Ac成為正值之情形時，使該調節力Ac之值存儲於計算裝置200。The adjustment power calculation unit 310 stores the value of the adjustment power Ac in the calculation device 200 when the adjustment power Ac of the wearer calculated according to the above formulas (1), (2) and (3) becomes a positive value.

加入度計算部320根據配方資料、第1距離及第2距離，計算中間部P處之適合配戴者之加入度及加入度率。該加入度係以遠用參考點FV為基準之值。加入度率成為將眼鏡鏡片之主注視線M上之某高度之加入度除以附加遠用參考點FV作為基準之近用參考點NV之加入度所得的值。The addition degree calculation part 320 calculates the addition degree and the addition degree rate of the suitable wearer at the middle part P according to the formula data, the first distance and the second distance. The degree of addition is a value based on the far reference point FV. The addition rate is a value obtained by dividing the addition degree of a certain height on the main gaze line M of the eyeglass lens by the addition degree of the near reference point NV with the additional far reference point FV as a reference.

圖4係表示眼鏡鏡片LS之加入度曲線CA之曲線圖。於圖4之曲線圖中，於橫軸表示加入度之值，於縱軸表示以眼點EP為基準之高度。遠用參考點FV之高度成為Lf（參照圖2），近用參考點NV之高度成為-Ln。與自高度-Ln至Lf為止對應之眼鏡鏡片LS之區域對應於中間部P。若將遠用參考點FV處之加入度設為0，將近用參考點NV處之加入度設為Add，將眼點EP處之加入度設為AddEP，則眼點EP處之加入度率EPP根據以下之式（4）求出。 EPP＝AddEP/Add…（4）Fig. 4 is a graph showing the addition curve CA of the spectacle lens LS. In the graph of FIG. 4, the horizontal axis represents the value of the addition degree, and the vertical axis represents the height based on the eye point EP. The height of the far reference point FV becomes Lf (refer to Fig. 2), and the height of the near reference point NV becomes -Ln. The area of the spectacle lens LS corresponding to the height -Ln to Lf corresponds to the middle portion P. If the addition degree at the far reference point FV is set to 0, the addition degree at the near reference point NV is set to Add, and the addition degree at the eye point EP is set to AddEP, then the addition degree rate at the eye point EP is EPP It is calculated by the following equation (4). EPP=AddEP/Add...(4)

於圖4之例中，以於中間部P位於較眼點EP更上方之部分之加入度曲線CA1與於中間部P位於較眼點EP更下方之部分之加入度曲線CA2具有不同之斜率之方式設定各基準點之加入度，但加入度曲線CA1及CA2亦可具有相同之斜率。In the example of FIG. 4, the addition curve CA1 at the middle part P above the eye point EP and the addition curve CA2 at the middle part P below the eye point EP have different slopes. Method to set the addition degree of each reference point, but the addition degree curves CA1 and CA2 can also have the same slope.

加入度計算部320基於第2距離、及調節力計算部310根據配方資料及第1距離計算出之調節力Ac，算出對中間部P之眼點EP附加之加入度AddEP及加入度率EPP。眼點EP處之加入度AddEP係以配戴者使用調節力之50%觀看第2距離之方式設定。因此，若將第2距離設為D2（單位為cm），則AddEP根據以下之式（5）計算。 AddEP＝100/D2－Ac/2…（5） 加入度計算部320於根據式（5）獲得之值為負之情形時，將眼點EP處之加入度AddEP設定為0。 再者，此處，眼點EP處之加入度AddEP以配戴者使用調節力之50%觀看第2距離D2之方式設定，但亦可使用40%或60%等適當設定之值。The addition degree calculation unit 320 calculates the addition degree AddEP and the addition degree rate EPP added to the eye point EP of the middle part P based on the second distance and the accommodation power Ac calculated by the adjustment power calculation unit 310 based on the recipe data and the first distance. AddEP at eyepoint EP is set by the way that the wearer uses 50% of the accommodation power to watch the second distance. Therefore, if the second distance is D2 (in cm), AddEP is calculated according to the following formula (5). AddEP=100/D2－Ac/2...(5) The addition degree calculation unit 320 sets the addition degree AddEP at the eye point EP to 0 when the value obtained according to formula (5) is negative. Furthermore, here, the addition degree AddEP at the eyepoint EP is set by the way that the wearer uses 50% of the accommodative power to view the second distance D2, but a value set appropriately such as 40% or 60% can also be used.

加入度計算部320根據式（4）計算眼點EP處之加入度率EPP。於加入度計算部320計算出之眼點EP處之加入度率EPP為既定之閾值以上且50%以下之情形時，顯示控制部214使顯示部203顯示用以向使用者推薦中近兩用鏡片之畫面。顯示部203例如可將「推薦中近兩用鏡片」等訊息顯示於該畫面。於加入度計算部320計算出之眼點EP處之加入度率EPP未達既定之閾值之情形時，顯示控制部214使顯示部203顯示用以向使用者推薦遠近兩用鏡片之畫面。顯示部203例如可將「推薦遠近兩用鏡片」等訊息顯示於該畫面。上述既定之閾值設定為10%以上且15%以下等範圍，例如可設定為10%、15%等。 再者，加入度計算部320亦可設為計算眼點EP處之加入度AddEP或加入度率EPP之任一者並存儲於計算裝置200之構成。The addition degree calculation unit 320 calculates the addition degree rate EPP at the eye point EP according to formula (4). When the addition degree EPP at the eye point EP calculated by the addition degree calculation unit 320 is greater than or equal to the predetermined threshold and less than 50%, the display control unit 214 displays the display unit 203 to recommend medium and near dual functions to the user The picture of the lens. The display unit 203 may display a message such as "recommended mid-near dual-use lens" on the screen, for example. When the addition degree rate EPP at the eye point EP calculated by the addition degree calculation unit 320 does not reach a predetermined threshold, the display control unit 214 causes the display unit 203 to display a screen for recommending a distance and near lens to the user. The display unit 203 can display a message such as "recommended distance and near lenses" on the screen, for example. The above-mentioned predetermined threshold is set in the range of 10% or more and 15% or less, for example, it can be set to 10%, 15%, etc. Furthermore, the addition degree calculation unit 320 can also be configured to calculate either the addition degree AddEP or the addition degree rate EPP at the eye point EP and store it in the calculation device 200.

計算部300之距離計算部330根據配方加入度、及調節力計算部320計算出之調節力Ac，計算配戴者通過近用部N觀看時之自配戴者至遠點之距離（以下，稱為第1遠點距離）及自配戴者至近點之距離（以下，稱為第1近點距離）、以及配戴者通過中間部P觀看時之自配戴者至遠點之距離（以下，稱為第2遠點距離）及自配戴者至近點之距離（以下，稱為第2近點距離）。深度方向表示沿著朝向配戴者之正面之視線之方向。此處，將配戴者通過眼鏡鏡片LS之某個位置觀看時不用調節眼睛便能夠明視之點稱為遠點，將最大限度調節眼睛而能夠明視之點稱為近點。 再者，距離計算部330不計算第1遠點距離、第1近點距離、第2遠點距離及第2近點距離之全部，計算至少一個即可。The distance calculation part 330 of the calculation part 300 calculates the distance from the wearer to the far point when the wearer looks through the near part N based on the formula addition degree and the accommodation force Ac calculated by the accommodation force calculation part 320 (hereinafter, Called the first far point distance) and the distance from the wearer to the near point (hereinafter referred to as the first near point distance), and the distance from the wearer to the far point when the wearer looks through the middle part P ( Hereinafter, referred to as the second far point distance) and the distance from the wearer to the near point (hereinafter referred to as the second near point distance). The depth direction indicates the direction along the line of sight toward the front of the wearer. Here, the point where the wearer can see clearly without adjusting his eyes when looking through a certain position of the spectacle lens LS is called the far point, and the point where the eye can be clearly seen by adjusting the eyes to the maximum is called the near point. In addition, the distance calculation unit 330 does not calculate all of the first far-point distance, the first near-point distance, the second far-point distance, and the second near-point distance, and it may calculate at least one.

(Modification 1) In the above-mentioned embodiment, it is also possible to input formula data, the first distance D1 and the second distance D2 and other values required for the calculation process of the calculation unit 300 through the touch panel integrated with the display unit 203 and the input unit 204.

圖10係本變形例之計算裝置200之立體圖。計算裝置200構成為平板等具有可攜性之裝置。計算裝置200例如係移動終端、個人電腦（以下，稱為PC）或與PC無線連接之終端裝置。計算裝置200具備觸控面板241及配置有觸控面板241之計算裝置本體部242。觸控面板241作為具備輸入部204及顯示部203之功能之輸入輸出介面發揮功能。若計算裝置200構成為具有可攜性之裝置，則不僅眼鏡店之店員，配戴者Wr等亦可於手邊確認並直接輸入資訊提供影像G2，因而較佳。FIG. 10 is a perspective view of the computing device 200 of this modification. The computing device 200 is configured as a portable device such as a tablet. The computing device 200 is, for example, a mobile terminal, a personal computer (hereinafter referred to as a PC), or a terminal device wirelessly connected to the PC. The computing device 200 includes a touch panel 241 and a computing device body 242 configured with the touch panel 241. The touch panel 241 functions as an input/output interface having the functions of the input unit 204 and the display unit 203. If the computing device 200 is configured as a portable device, not only the clerk of the spectacle shop, but also the wearer Wr, etc. can also confirm on hand and directly input the information to provide the image G2, which is preferable.

（變形例2） 於上述實施形態中，亦可進而基於配戴者Wr通過遠用部F觀看之距離（第3距離）而計算眼鏡鏡片LS之光學特性相關之數值。(Modification 2) In the above-mentioned embodiment, the value related to the optical characteristics of the spectacle lens LS may be calculated based on the distance (the third distance) that the wearer Wr sees through the distance portion F.

距離獲取部212基於來自輸入部204之輸入等獲取第3距離，並存儲於計算裝置200。The distance acquiring unit 212 acquires the third distance based on input from the input unit 204 and the like, and stores it in the computing device 200.

圖11係表示配合第3距離使遠用參考點FV之球面度數變化時之加入度曲線之曲線圖。加入度曲線CA10表示第3距離為無限遠之情形時之例，加入度曲線CA20表示使第3距離變化為有限值之情形時之例。Fig. 11 is a graph showing the addition curve when the spherical power of the far reference point FV is changed according to the third distance. The addition degree curve CA10 shows an example when the third distance is infinite, and the addition degree curve CA20 shows an example when the third distance is changed to a finite value.

加入度計算部320根據以下之式（12）自配方資料之值（此處，第3距離為無限遠之情形）變更球面度數S之數值，使得配戴者Wr無須進行調節便可通過遠用部F觀看第3距離。將變更後之S設為S*，將第3距離D3之單位設為m。 S*＝S＋1/D3…（12） 例如，配方資料中球面度數為-3.00，且第3距離D3為4 m（0.25 D）之情形時，加入度計算部320將球面度數之數值設定為-2.75。The addition degree calculation unit 320 changes the value of the spherical power S from the value of the formula data (here, the third distance is infinite) according to the following formula (12), so that the wearer Wr can pass the distance without adjustment Part F looks at the 3rd distance. Set the changed S to S*, and set the unit of the third distance D3 to m. S*=S＋1/D3...(12) For example, when the spherical power in the recipe data is -3.00 and the third distance D3 is 4 m (0.25 D), the addition degree calculation unit 320 sets the spherical power value to -2.75.

加入度計算部320根據以下之式（13）再次計算近用參考點NV處之加入度Add。 Add＝Addp－1/D3…（13） 由於加入度之值以遠用參考點FV為基準，故若第3距離D3自無限遠變化為4 m，則加入度成為0之點自圖11之曲線圖橫軸之O1向O2（＝O1－0.25）移動。由於加入度Add成為自O1或O2至配方加入度Addp為止之值，故若第3距離D3自無限遠變化為4 m，則加入度Add變小0.25。若第3距離D3自無限遠變化為4 m，則加入度曲線CA10變化為加入度曲線CA20而設定。The addition degree calculation unit 320 calculates the addition degree Add at the near reference point NV again according to the following formula (13). Add=Addp－1/D3...(13) Since the value of the addition degree is based on the far reference point FV, if the third distance D3 changes from infinity to 4 m, the addition degree becomes 0 from the point O1 on the horizontal axis of the graph in Fig. 11 to O2 (=O1－ 0.25) Move. Since the addition degree Add becomes a value from O1 or O2 to the formula addition degree Addp, if the third distance D3 changes from infinity to 4 m, the addition degree Add becomes smaller by 0.25. If the third distance D3 changes from infinity to 4 m, the addition curve CA10 changes to the addition curve CA20 and is set.

加入度計算部320係配合成為加入度Add之基準之點自O1變化為O2，而再次計算眼點EP處之加入度AddEP及加入度率EPP。變更後之眼點EP處之加入度AddEP*及加入度率EPP*分別根據以下之式（14）及式（15）獲得。 AddEP*＝AddEP－1/D3…（14） EPP*＝AddEP*/Add…（15） 於該情形時，雖然眼點EP處之加入度及加入度率變化，但眼點EP及近用參考點NV處之折射力不變化。The addition degree calculation unit 320 changes the addition degree AddEP and the addition degree rate EPP at the eye point EP according to the point that becomes the basis of the addition degree Add from O1 to O2. The addition degree AddEP* and the addition degree rate EPP* at the eye point EP after the change are obtained according to the following equations (14) and (15) respectively. AddEP*=AddEP－1/D3...(14) EPP*=AddEP*/Add...(15) In this case, although the addition degree and the addition degree rate at the eye point EP change, the refractive power at the eye point EP and the near reference point NV does not change.

若第3距離D3變短，則變更後之成為加入度Add之基準之點O2於圖11之曲線圖之橫軸上向右側移動，加入度率EPP*成為既定值以下。於該情形時，計算部300可將關於該第3距離D3之光學特性相關之計算中止。上述既定之閾值設定為10%以上15%以下等範圍，例如可設定為10%、15%等。If the third distance D3 becomes shorter, the changed point O2, which becomes the reference of the addition degree Add, moves to the right on the horizontal axis of the graph of FIG. 11, and the addition degree rate EPP* becomes the predetermined value or less. In this case, the calculation unit 300 may stop the calculation related to the optical characteristics of the third distance D3. The above-mentioned predetermined threshold is set in the range of 10% to 15%, etc., for example, it can be set to 10%, 15%, etc.

範圍計算部340根據加入度計算部310基於第3距離D3計算出之加入度曲線CA20，再次計算第1明視範圍W1、第2明視範圍W2、第1對象側明視範圍Wn及第2對象側明視範圍Wp。The range calculation unit 340 recalculates the first clear view range W1, the second clear view range W2, the first object side clear view range Wn, and the second clear view range Wn, and the second clear view range Wn based on the addition level curve CA20 calculated by the addition level calculation unit 310 based on the third distance D3. The subject side bright vision range Wp.

影像生成部213生成資訊提供影像，該資訊提供影像包含藉由加入度計算部320及範圍計算部340基於第3距離D3進行計算所得的關於眼鏡鏡片LS之光學特性之數值相關之資訊。該數值包含上述之眼點EP處之加入度AddEP*及加入度率EPP*、第1對象側明視範圍Wn及第2對象側明視範圍Wp。The image generating unit 213 generates an information providing image, which includes information related to the numerical value of the optical characteristic of the eyeglass lens LS calculated by the addition degree calculating unit 320 and the range calculating unit 340 based on the third distance D3. This value includes the above-mentioned addition degree AddEP* and addition degree rate EPP* at the eye point EP, the first subject side bright vision range Wn, and the second subject side bright vision range Wp.

圖12係第3距離D3為無限遠（變更前）之情形時之資訊提供影像G3。資訊提供影像G3由於第3距離D3為無限遠，故與眼鏡鏡片LS之光學特性相關之數值為與圖7相同之值。Fig. 12 is the information providing image G3 when the third distance D3 is infinite (before the change). Since the third distance D3 of the information providing image G3 is infinite, the value related to the optical characteristics of the spectacle lens LS is the same value as in FIG. 7.

資訊提供影像G3與上述之實施形態之資訊提供影像G2相比，不同之處在於具備第3距離輸入部500，進而具備遠用部資訊顯示部50a代替遠用部資訊顯示部50。The information providing image G3 is different from the information providing image G2 of the above-mentioned embodiment in that it includes a third distance input unit 500 and further includes a distance information display unit 50a instead of the distance information display unit 50.

第3距離輸入部500具備滑動條501、數值指定標記502及決定圖標511。根據數值指定標記502處於滑動條501之哪一位置，選擇輸入之第3距離D3。於圖12、圖13之例中，以如下方式設定，即，於滑動條上，越是向左前進則第3距離D3之值越小，越是向右前進則第3距離D3之值越大。數值指定標記502可藉由滑鼠拖動或藉由描劃觸控面板而移動。選擇之第3距離D3之數值顯示於虛線之矩形512內，藉由點擊決定圖標511等而輸入該數值作為第3距離D3。The third distance input unit 500 includes a slider 501, a numerical value designation mark 502, and a determination icon 511. According to the numerical designation mark 502 at which position of the slider 501, the input third distance D3 is selected. In the example of Fig. 12 and Fig. 13, it is set as follows, that is, on the slide bar, the value of the third distance D3 decreases as you advance to the left, and the value of the third distance D3 increases as you advance to the right. Big. The value designation mark 502 can be moved by dragging with a mouse or by dragging the touch panel. The value of the selected third distance D3 is displayed in the dotted rectangle 512, and the value is input as the third distance D3 by clicking the determination icon 511 or the like.

遠用部資訊顯示部50a係以虛線之圓52表示遠用參考點FV之位置，以圓52與虛線53建立對應而示出第3距離D3之最小值（虛線之矩形55之內部）。進而，於遠用部資訊顯示部50a示出第3距離D3之最大值（虛線之矩形56之內部）。該等最小值及最大值係藉由利用加入度計算部310對複數個第3距離D3計算眼點EP處之加入度率EPP、EPP*，並求出該加入度率EPP、EPP*處於既定範圍之第3距離D3之最小值及最大值而預先獲取。可經由上述滑動條501選擇之數值範圍較佳為設為該最小值與最大值之間之數值。The distance information display unit 50a uses the dotted circle 52 to indicate the position of the distance reference point FV, and the circle 52 corresponds to the dotted line 53 to show the minimum value of the third distance D3 (the inside of the dotted rectangle 55). Furthermore, the maximum value of the third distance D3 (inside the rectangle 56 of the dotted line) is displayed on the distance information display section 50a. These minimum and maximum values are calculated by using the addition degree calculation unit 310 to calculate the addition degree rates EPP and EPP* at the eye point EP for a plurality of third distances D3, and obtain the addition degree rates EPP and EPP* at a predetermined value The minimum and maximum values of the third distance D3 of the range are obtained in advance. The range of values that can be selected via the slide bar 501 is preferably set to a value between the minimum and maximum values.

圖13係第3距離D3為1 m之情形時之資訊提供影像G4。資訊提供影像G4係於數值指定標記502移動至左端之後，點擊決定圖標511，藉此輸入1 m作為第3距離D3後的影像。資訊提供影像G4與資訊提供影像G3相比，第3距離D3自無限遠變化為1 m，因此，基本資訊顯示部41中表示之球面度數（S）、加入度顯示部42中表示之眼點EP處之加入度AddEP*、加入度率顯示部43中表示之加入度率EPP*、第1對象側明視範圍Wn及第2對象側明視範圍Wp之值變化。Fig. 13 is an information providing image G4 when the third distance D3 is 1 m. For the information providing image G4, after the numerical value designation mark 502 is moved to the left end, the determination icon 511 is clicked to input 1 m as the image after the third distance D3. Compared with the information providing image G3, the third distance D3 changes from infinity to 1 m in the information providing image G4. Therefore, the spherical power (S) shown in the basic information display section 41 and the eye point shown in the addition degree display section 42 The addition degree AddEP* at EP, the addition degree rate EPP* displayed in the addition degree rate display part 43, the first object side bright vision range Wn, and the second object side bright vision range Wp change in value.

資訊提供影像G3、G4係構成為配戴者Wr等使用者可適當變更第3距離D3，且成為伴隨該變更而隨時顯示更新後之加入度AddEP*、以及第1對象側明視範圍Wn及第2對象側明視範圍Wp的構成。藉此，使用者可將利用遠用部F能夠明視至何種程度之距離與利用中間部P及近用部N之能夠明視之範圍進行比較，選擇具有所期望之外觀之眼鏡鏡片LS。 再者，於如變形例1所示般輸入部204由觸控面板241構成之情形時，配戴者Wr等使用者可簡便地藉由描劃觸控面板241之滑動條501而移動數值指定標記502或觸摸滑動條501而移動數值指定標記來設定第3距離D3，而較佳。The information providing images G3 and G4 are configured so that users such as the wearer Wr can appropriately change the third distance D3, and the updated addition degree AddEP* and the first object side bright vision range Wn and The structure of the second object side clear view range Wp. Thereby, the user can compare the distance to which the far part F can be seen clearly with the visible range of the middle part P and the near part N, and select the eyeglass lens LS with the desired appearance . Furthermore, when the input unit 204 is composed of the touch panel 241 as shown in Modification 1, users such as the wearer Wr can easily move the numerical value designation by drawing the slider 501 of the touch panel 241 It is better to mark 502 or touch the slide bar 501 to move the value designation mark to set the third distance D3.

圖14及圖9係表示本變形例之計算方法以及本變形例之影像生成方法、資訊提供方法、眼鏡鏡片之設計方法及眼鏡鏡片之製造方法之流程的流程圖。自步驟S301至S305為止係與圖8之流程圖之自步驟S101至S105為止相同，因此省略說明。步驟S305結束後，開始步驟S307。Figures 14 and 9 are flowcharts showing the flow of the calculation method of this modification, the image generation method, the information providing method, the design method of spectacle lenses, and the manufacturing method of spectacle lenses. The steps S301 to S305 are the same as the steps S101 to S105 in the flowchart of FIG. 8, and therefore the description is omitted. After step S305 ends, step S307 is started.

於步驟S307中，範圍計算部340基於第3距離D3，計算眼點EP處之加入度AddEP、AddEP*及加入度率EPP、EPP*。步驟S307結束後，開始步驟S309。於步驟S309中，距離計算部330計算遠點距離及近點距離。步驟S309結束後，開始步驟S311。In step S307, the range calculation unit 340 calculates the addition degrees AddEP and AddEP* and the addition degree rates EPP and EPP* at the eyepoint EP based on the third distance D3. After step S307 ends, step S309 is started. In step S309, the distance calculation unit 330 calculates the far point distance and the near point distance. After step S309 ends, step S311 starts.

於步驟S311中，範圍計算部340基於第3距離D3，計算對象側明視範圍（第1對象側明視範圍Wn及第2對象側明視範圍Wp）。步驟S311結束後，開始步驟S313。於步驟S313中，影像生成部213生成資訊提供影像G3或G4，顯示控制部214於顯示部213顯示資訊提供影像G3或G4。步驟S313結束後，開始步驟S315。In step S311, the range calculation unit 340 calculates the object side bright vision range (the first object side bright view range Wn and the second object side bright view range Wp) based on the third distance D3. After step S311 ends, step S313 is started. In step S313, the image generating unit 213 generates the information providing image G3 or G4, and the display control unit 214 displays the information providing image G3 or G4 on the display unit 213. After step S313 ends, step S315 is started.

於步驟S315中，控制部210判定是否已輸入結束資訊提供影像G3或G4之顯示之指示。於已輸入該指示之情形時，控制部210對步驟S315作出肯定判定而開始步驟S201（圖9）。步驟S201及其之後之處理與上述實施形態相同，因此省略說明。於尚未輸入該指示之情形時，控制部210對步驟S作出否定判定而開始步驟S317。於步驟S317中，距離獲取部212獲取第3距離D3。步驟S317結束後，返回至步驟S307。In step S315, the control unit 210 determines whether an instruction to end the display of the information providing image G3 or G4 has been input. When the instruction has been input, the control unit 210 makes a positive determination to step S315 and starts step S201 (FIG. 9 ). The processing in and after step S201 is the same as in the above-mentioned embodiment, so the description is omitted. When the instruction has not been input, the control unit 210 makes a negative judgment on step S and starts step S317. In step S317, the distance acquiring unit 212 acquires the third distance D3. After step S317 ends, return to step S307.
