Description

  The present invention relates to a spectacle lens ordering method, and more particularly to a spectacle lens ordering method suitable for ordering a spectacle lens with a decoration.

  Conventionally, eyeglass lenses have been used for correcting wearers' vision. In recent years, not only correction of visual acuity but also dyeing spectacle lenses has realized dyeing lenses that have a function of efficiently cutting short-wavelength light and reducing glare.

  In addition, eyeglass lenses are becoming more important not only as a sight correction tool but also as a fashion item. For example, in order to make the skin color look beautiful, a stained lens in which a wearer selects a favorite color from various color variations and has the selected color is realized.

  As a method for selecting a color of an eyeglass lens, Patent Document 1 discloses that a frame of a plurality of types of base designs prepared in advance on a display screen by an interactive method using means including a computer-controlled display screen. Select any one, and change the appearance design including the color of the lens based on the frame of the selected base design, so that the eyeglasses order (wearer) can be selected on the display screen. It describes a custom-made system for eyeglasses that can determine and order the optimum spectacle specs according to the order.

International Publication No. 98/052092 Pamphlet

  In the eyeglasses custom-made system described in Patent Document 1, it is possible to select eyeglasses by selecting an appearance design such as a lens color according to the preference of the eyeglass orderer. However, it can be determined only by the image on the display screen whether the lens is an appearance design desired by the eyeglass orderer. As a result, there is a problem that the appearance design of the ordered lens is different from the appearance design assumed by the eyeglass orderer. There are various causes for this defect, but as an example, the color calibration of the display screen is insufficient and the color cannot be displayed accurately. In addition, the spectacle orderer may not be able to determine whether or not the lens is suitable for his / her favorite appearance design without actually trying it on.

  On the other hand, in order to check whether the lens conforms to the external appearance design of the spectacle orderer, if the spectacle orderer actually tries on, the lens is not suitable for the external appearance design. This necessitates the reworking of a try-on lens. As a result, the cost required for creating a lens for fitting will increase.

  The present invention has been made in view of such circumstances, and spectacle lenses capable of ordering spectacle lenses that are as identical as possible to the external appearance design of the lenses expected by the spectacle orderer at the lowest possible cost. The purpose is to realize a lens ordering method.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms or application examples.

  [Application Example 1] The spectacle lens ordering method according to this application example includes: (a) creating a lens base material according to the shape of the spectacle frame; and (b) allowing the wearer to select the appearance design of the spectacle lens. And (c) creating a fitting lens by forming a decoration layer on the lens substrate based on the selected appearance design, and (d) mounting the fitting lens on the spectacle frame. And (e) removing the fitting lens from the spectacle frame when the wearer evaluates that the fitting lens does not conform to a desired appearance design; and (f) after (e) Removing the decorative layer formed on the fitting lens; and (g) (b), (c), (d) until the wearer evaluates that the fitting lens conforms to the desired appearance design. ), ( ) And (f), and (h) the spectacle lens including information on the selected appearance design when the fitting lens is evaluated by the wearer to match the desired appearance design. Sending order information.

  According to this application example, for example, the lens base material is created in accordance with the shape of the spectacle frame selected by the wearer. Then, the wearer can select the appearance design of the spectacle lens, and based on the selected appearance design, a decoration layer can be formed on the created lens base material to create a fitting lens. By mounting this fitting lens on the above-mentioned spectacle frame, it is possible to try on a fitting lens having an appearance design selected by the wearer himself / herself and to actually confirm whether or not it is his / her favorite appearance design.

  If the wearer evaluates that the fitting lens does not conform to the desired appearance design, the fitting lens is removed from the spectacle frame, and the formed decorative layer is removed from the fitting lens. Then, the fitting lens (lens substrate) from which the decoration layer has been removed is used again to select the appearance design, form the decoration layer, and attach the fitting lens to the spectacle frame. Can be repeated until evaluated. The spectacle lens actually purchased by the wearer can be ordered by transmitting the spectacle lens ordering information based on the information on the external appearance design evaluated to be suitable for the desired external appearance design.

  By doing so, the spectacle lens can be ordered after the wearer can confirm that the appearance design is his / her favorite by fitting. As a result, it is possible to reduce the occurrence of a problem that the delivered spectacle lens is different from the appearance design of the lens assumed by the wearer. In addition, since the lens base material can be reused even when repeatedly trying on, the cost required for fitting can be reduced.

  Application Example 2 In the spectacle lens ordering method according to the application example described above, forming the decoration layer includes applying a decoration liquid containing an organic polymer having a polar group to the lens substrate. May be included.

  According to this application example, the decoration layer is formed on the lens substrate by applying the decoration liquid containing the organic polymer having a polar group. It is known that a decoration layer formed of a decoration liquid containing an organic polymer having a polar group can be removed relatively easily. Therefore, when it is evaluated that the wearer does not conform to the selected appearance design as a result of the fitting by the wearer, it is easy to remove the decoration layer and form a new decoration layer again. It becomes possible.

  Application Example 3 In the spectacle lens ordering method according to the application example described above, the application of the decoration liquid may be performed by applying the decoration liquid by an inkjet method.

  According to this application example, the decoration layer is formed by applying the decoration liquid by an inkjet method. Since the inkjet method can selectively apply a decoration liquid to a lens substrate, a wide variety of appearance designs can be applied to a fitting lens.

  Application Example 4 In the spectacle lens ordering method according to the application example described above, the lens base material may be created using a finished product lens selected based on the wearer's prescription.

  According to this application example, the lens base material is created using the finished product lens selected based on the wearer's prescription. When creating a try-on lens, for example, there is a concept of using a lens base material having a certain frequency regardless of the prescription of the wearer. However, if the prescription power required by the wearer and the power of the fitting lens are significantly different, it is difficult for the wearer to confirm whether or not the fitting lens is suitable for the selected external design. .

  In that regard, in the spectacle lens ordering method according to this application example, a lens base material is created using a finished product lens selected based on the wearer's prescription, so for example, for a wearer who needs to prescribe a plus power. For wearers who need to prescribe a minus power lens base material, a try-on lens can be made using a minus power lens base material. As a result, the wearer can try on using a fitting lens having a degree suitable for the wearer to some extent, so that the wearer can easily check himself / herself whether or not it conforms to the selected appearance design. it can.

  Application Example 5 In the spectacle lens ordering method according to the application example described above, it is preferable that the appearance design is at least one of a color, a gradation, and a pattern imparted to the spectacle lens.

  According to this application example, at least one of a color, a gradation, and a pattern can be given as the appearance design of the spectacle lens, and an appearance design that meets the various needs of the wearer can be provided.

May be.

1-2. Procedure of spectacle lens ordering method 1-2-1. FIG. 3 is a flowchart of a spectacle lens ordering method performed on the spectacle sales store 100 side. In the spectacles store 100, first, a prescription measurement of a user who purchases spectacles is performed (step S300). The prescription frequency (correction frequency) to be prescribed to the user is determined by the prescription measurement. The prescription power is generally expressed by quantifying the spherical power (S), the astigmatism power (C), and the astigmatism direction (AX). When the lens to be ordered is a bifocal lens or a progressive power lens, S, C, and AX are obtained for the distance portion and the near portion, respectively.

  Next, the user selects a spectacle frame on which the lens to be ordered is mounted (step S302). The eyeglass frame is performed by the user selecting a preferred eyeglass frame from those displayed at the storefront of the eyeglass store 100.

  Next, the spectacles store 100 selects a finished product lens to be used for fitting (step S304). In selecting the finished product lens, the same finished product lens may be selected uniformly regardless of the measured prescription power, but it is preferable to select the finished product lens based on the prescription power. If the finished lens is selected based on the measured prescription power, the shape of the lens to be used for fitting will be close to the shape of the lens to be ordered finally, and the fitting may be performed in a form close to the actual wearing image. it can. Furthermore, since it is possible to try on using a lens for try-on that is close to the prescription power, the user can easily confirm whether the result of the try-on is good or bad.

  In addition, when there is no inventory of finished lenses having the measured prescription power in the spectacle store 100, a finished product lens having a prescription power range close to the prescription power is selected from the finished product lenses in stock. Also good. The stock status of the spectacles store 100 can be grasped by referring to the lens stock database 214 stored in the storage unit 208 of the PC 104.

  Returning to the description of FIG. When the appearance design is selected in step S308, a decorative layer is formed using the first lens printing apparatus 106 (step S310). Specifically, the trial wearing lens base material created in step S306 is set at a predetermined position of the first lens printing apparatus 106, and a printing command is issued from the PC 104 to the first lens printing apparatus 106. When the print command is issued, the arithmetic processing unit 206 reads out and executes the first lens printing apparatus control program 218 from the storage unit 208, and performs color conversion and binarization of the image data representing the appearance design selected in step S308. To generate a print description language in which print contents are described. Then, when the print description language generated by the first lens printing apparatus control program 218 is transmitted to the first lens printing apparatus 106, the first lens printing apparatus 106 starts operation, and the recording materials of the respective colors are prepared according to the printing description language. It applies to a trial wearing lens base material, and a decoration layer is formed in the trial wearing lens base material. The process of step S310 is performed for the right eye, the left eye, and each trial wear lens substrate. Hereinafter, the trial wearing lens base material on which the decorative layer is formed is referred to as a “fitting lens”.

  Since the try-on lens is a trial-wear lens and is not a finished lens that is finally delivered to the user, a hard coat layer, an antireflection layer, an antifouling layer, and the like are not added. As a result, the decorative layer can be removed as easily as possible, and the trial wear lens base material can be easily reused.

  Next, a spectacles engineer who is a salesclerk of the spectacles store 100 attaches a fitting lens to the spectacle frame selected in step S302 (step S312). This is the so-called “frame”. When the frame work is finished, the glasses for trial wear are completed.

  Next, the user actually tries on eyeglasses for trial wearing, and the user evaluates whether or not the fitting lens conforms to the user's favorite appearance design (step S314). A feature of this embodiment is that the user is asked to evaluate whether or not it conforms to the user's favorite appearance design after actually trying it on.

  In step S314, if it is evaluated that the fitting lens does not conform to the appearance design as a result of the user's fitting (step S314: No), the spectacles engineer attaches the fitting lens to the glasses in order to try on a different appearance design. Remove from the frame (step S316).

  After step S316, the decorative layer formed on the fitting lens is removed (step S318). Specifically, the decorative layer is removed by wiping off the fitting lens using a nonwoven fabric impregnated with alcohol or an organic solvent. The operation of wiping off the fitting lens may be performed by a store clerk of the spectacles store 100, or may be performed by using a dedicated decorative layer removing device having a mechanism for wiping off the fitting lens using a nonwoven fabric.

  After step S318, the process returns to step S308, and the appearance design is selected again. The selection of the appearance design here is, for example, a review of the appearance design with a focus on setting items that do not match the user's preference as a result of fitting.

  When the review of the appearance design is completed in step S308, a fitting lens is created by forming a decoration layer using the image data representing the newly selected appearance design on the trial wearing lens substrate from which the decoration layer has been removed. Then, the fitting lens is attached to the spectacle frame (step S312).

  Here, the feature of this embodiment is that the trial wear lens base material is reused. In the present embodiment, since the decorative layer can be removed from the try-on lens base material, it is not necessary to create a new try-on lens base material, and the cost required for try-on can be reduced.

  Then, the process proceeds again to step S314, in which the user actually tries on the glasses for try-on, and the user evaluates whether or not the try-on lens conforms to the desired appearance design.

  In this way, until it is evaluated in step S314 that the fitting lens matches the user's preferred appearance design, the appearance design is selected (step S308), the decoration layer is formed (step S310), and the fitting lens is attached to the spectacle frame. The mounting (step S312), the removal of the fitting lens from the spectacle frame (step S316), and the decoration layer removal (step S318) are repeated.

  On the other hand, if it is evaluated in step S314 that the fitting lens conforms to the user's preferred appearance design as a result of the user's fitting (step S314: Yes), the order data is sent to the lens via the communication unit 210 of the PC 104. The data is transmitted to the order receiving server 122 of the processor 120 (step S320). The order data includes at least information on the appearance design, specifically image data representing the appearance design, data on the prescription frequency to be prescribed to the user, and data on the three-dimensional shape of the spectacle frame.

1-2-2. FIG. 5 is a flowchart of a spectacle lens ordering method performed on the lens processor 120 side. In the lens processing company 120, first, the order receiving server 122 receives order data transmitted from the spectacles store 100 (step S500).

  Next, the lens processor 120 selects a semi-finished product lens to be used when creating a finished product lens (step S502). In general, semi-finished lenses use semi-finished lenses of the same shape for a certain prescription power range. Therefore, in selecting a semi-finished product lens, a semi-finished product lens that includes the prescription power of the order data within the prescription power range may be selected by referring to the data regarding the prescription power included in the order data.

  Next, the selected semi-finished product lens is cut and polished according to the prescription frequency of the order data (step S504). Specifically, using the second lens processing machine 124, the semi-finished product lens is cut and polished in accordance with the prescription frequency of the order data. In step S504, the finished lens obtained by cutting and polishing is not processed to match the shape of the spectacle frame.

  Next, using the second lens printing device 126, a decorative layer is formed on the finished lens cut and polished in step S504 (step S506). Specifically, the finished product lens obtained in step S504 is set at a predetermined position of the second lens printing device 126, and a print command is issued from the order receiving server 122 to the second lens printing device 126. When a print command is issued, a second lens printing apparatus control program stored in a storage unit (not shown) of the order receiving server 122 is activated, and color conversion and binarization of image data representing an external design included in the order data are performed. To generate a print description language in which print contents are described. Then, when the print description language generated by the second lens printing apparatus control program is transmitted to the second lens printing apparatus 126, the second lens printing apparatus 126 starts to operate and records the recording materials of each color according to the printing description language. It is applied to the finished lens that has been cut and polished in S504, and a decorative layer is formed on the finished lens. The process in step S506 is performed for the right eye, the left eye, and each finished product lens.

  Next, using the coating device 128, a coat layer is formed on the finished lens on which the decoration layer has been formed in step S506 (step S508). As the coating layer, for example, a hard coating layer, an antireflection layer, an antistatic layer, an antifouling layer, or an antifogging layer can be formed. Data relating to the coat layer to be formed may be included in the order data, and the coat layer to be formed may be selected according to the order data.

  Next, using the second lens processing machine 124, the finished lens on which the coat layer is formed is processed according to the shape of the spectacle frame (step S510). This is the so-called target processing. Specifically, the second lens processing machine 124 refers to data relating to the three-dimensional shape of the spectacle frame included in the order data, and processes the finished product lens on which the coat layer is formed to create a product lens.

  Finally, the lens processor 120 sends the product lens to the eyeglass store 100 (step S512) and delivers it to the user.

  By doing so, the spectacle lens can be ordered after the user can confirm that the appearance design is his / her favorite by fitting. As a result, it is possible to reduce the occurrence of the problem that the delivered spectacle lens is different from the lens appearance design assumed by the user.

  Therefore, for the spectacle store 100, it is possible to suppress a decrease in the customer satisfaction of the user due to the above-described problems.

  For the lens processor 120, it is possible to reduce the labor and cost of reordering spectacle lenses due to the above-mentioned problems.

  On the other hand, for the user, the delivery delay of the spectacle lens caused by the above-mentioned problem is reduced, and the ordered spectacle lens can be used without waiting for a long time.

2. Modifications The present invention is not limited to the above-described embodiment, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible. In the description of the modification, the same components as those in the above-described embodiment are denoted by the same reference numerals, and the description thereof is omitted.

2.1. Designation of gradation In the above-described embodiment, the direction of gradation, which is a setting item of the external appearance design of the lens, is the vertical direction. However, the present invention is not limited to this, and the direction of gradation may be set to an arbitrary direction. In the above embodiment, the gradation is a gradation that goes from the selected color toward colorless. However, the gradation is not limited to this, and a gradation that transitions between a plurality of colors may be designated.

2.2. Appearance design of right-eye lens and left-eye lens In the above embodiment, the right-eye lens and the left-eye lens have the same or left-right example of the appearance design. Different appearance designs may be set for the eye lens and the left eye lens.

2.3. Display of Appearance Design Confirmation Area In the above-described embodiment, the spectacle lens image 410 is displayed in the appearance design confirmation area 400. However, an image of spectacles that combines the spectacle frame image and the spectacle lens image 410 selected by the user is displayed. May be displayed.

  For example, the barcode of the eyeglass frame selected by the user is read, and the corresponding frame data is read from the frame shape database 212 and displayed in the appearance design confirmation area 400. The frame shape data may include data regarding the color and pattern of the frame.

  In this way, the appearance of the glasses can be confirmed, so that the user can easily select a combination of the frame design and the lens appearance design closer to the desired appearance. Therefore, it is possible to reduce the time and labor required for creating and trying on a fitting lens.

2.4. Separation of Functions In the above embodiment, the function of selecting the appearance design by the PC 104 and the function of transmitting the order data to the order receiving server 122 are realized. However, the present invention is not limited to this, and the function of selecting the appearance design and the order data The function of transmitting the information may be realized using a separate computer.

2.5. In the above embodiment, the lens processing company 120 is configured to send a product lens obtained by processing a finished lens in accordance with the shape of the spectacle frame to the spectacle sales shop 100. However, the present invention is not limited to this, and the lens processor 120 sends the finished lens, which has been cut / polished, formed a decorative layer, and formed a coat layer in accordance with the prescription, to the spectacles store 100. The finished lens may be processed according to the shape of the spectacle frame.

  In this way, it becomes easy to perform processing for the purpose of final fine adjustment in the spectacles store 100. Further, it is not necessary to include data relating to the three-dimensional shape of the spectacle frame in the order data.

2.6. Test wear spectacle frame In the above-described embodiment, the configuration is such that the test wear lens base material is created according to the shape of the spectacle frame selected by the user. Also good.

  In this way, it is not necessary to individually create a trial lens base material according to the shape of the spectacle frame. That is, since a trial lens base material can be prepared in advance according to the shape of the trial spectacle frame, labor and cost for creating the trial lens base material can be saved.

  In addition, if the eyeglass frame for trial wear is determined in advance, the shape of the lens base material for trial wear will not change depending on the user's choice, so use a common lens base material for different users. The cost required for fitting can be further reduced.

2.7. Color Management In the above embodiment, it is preferable that the first lens printing device 106 and the second lens printing device 126 have the same output characteristics. However, a known color management technique is adopted as a specific realization means. May be.

  For example, an ICC profile is embedded in image data representing an external design. When the decoration layer is formed by the first lens printing apparatus 106, the RGB color space of the image data representing the external appearance design is not dependent on a device (for example, CIELAB) according to the ICC profile embedded in the image data. ). Thereafter, the CIELAB color space is converted into the CMYK color space according to the ICC profile (device profile) assigned to the first lens printing apparatus 106.

  On the other hand, when forming the decoration layer with the second lens printing device 126, the ICC profile embedded in the image data representing the appearance design included in the order data is read, and the RGB color space of the image data representing the appearance design is read out. Similarly, conversion to the CIELAB color space is performed. Thereafter, the CIELAB color space is converted into the CMYK color space according to the ICC profile (device profile) assigned to the second lens printing device 126.

  In this way, since color conversion can be performed via a color space that does not depend on the device, the color difference between the colors output by the first lens printing device 106 and the second lens printing device 126 is within a predetermined range. Can be suppressed.

2.8. 1st lens processing machine In the above-mentioned embodiment, although the 1st lens processing machine 102 was set as the structure which processes a finished product lens according to the shape of a spectacles frame, the 1st lens processing machine 102 is further matched with prescription frequency. And a mechanism for cutting and polishing the semi-finished lens.

  When creating a finished product lens using the first lens processing machine 102, the eyeglass dealer 100 selects a semi-finished product lens in step S304, and in step S306, cutting and polishing of the semi-finished product lens and a finished product lens are performed. And processing. In the selection of the semi-finished product lens, it is preferable to select a semi-finished product lens that includes the measured prescription power within the prescription power range. Since the shape of the lens to be used for fitting is close to the shape of the lens to be finally ordered, the fitting can be performed in a form close to the actual wearing image. Furthermore, since fitting can be performed using a fitting lens having a power close to the prescription power, the user can easily confirm whether the result of the fitting is good or bad.

2.9. Test wear lens base material The above embodiment and modification 2.8. In this case, the finished lens or the semi-finished lens is selected based on the prescription power, but the trial lens base material may be created using the same finished lens uniformly regardless of the prescription power. .

  In this way, it is not necessary to individually create a lens base material for trial use according to the prescription power, so it is possible to use a common lens base material for different users, and it is necessary to try on. Costs can be further reduced.

  When using a uniform finished lens, it is preferable to use a weak or plano lens to accommodate users with different vision. In addition, lenses with several degrees of power may be prepared. For example, by preparing lenses with a positive strength, a positive weakness, a negative strength, and a negative weakness, the cost can be reduced and the shape of the fitting lens can be brought closer to the actual wearing image. . Furthermore, it becomes easier for the user to confirm whether the result of the fitting is good or bad.

  The material of the trial wear lens substrate may be the same as or different from the material of the product lens. If the same material is used, it is possible to reduce the occurrence of a problem that the delivered spectacle lens and the fitting lens are different in appearance. On the other hand, if a material that is cheaper and easier to process than the material of the product lens is used, the cost required for fitting can be further reduced. When the materials of the product lens and the fitting lens are different, it is preferable to use a material that can obtain a fitting lens having an appearance that is as close to the appearance of the product lens as possible.
