Description

  The present invention relates to a spectacle lens ordering / ordering system, a spectacle lens ordering program, and a spectacle lens ordering method that can cope with the deformation of a lens shape of a spectacle lens.

  The spectacle lens ordering / ordering system includes a terminal device (hereinafter simply referred to as “ordering side device”) disposed in a spectacle store (that is, an ordering side for spectacle lenses), and a processing center of an eyeglass lens manufacturer (that is, lens processing for spectacle lenses). Terminal device (hereinafter simply referred to as “order receiving side device”) arranged on the communication side such as the Internet. Then, when data on the lens shape (lens shape) of the spectacle frame desired by the customer, the lens type, the lens material, the lens prescription value, etc. is input by the operation of the store clerk at the ordering side device, By sending the input data to the order receiving side device, the eyeglass lens is ordered. On the other hand, in the order-receiving device, the outer diameter shape of the raw lens that is the basis of the spectacle lens is processed into a specified target lens shape while following the contents of the transmission data from the order-receiving device.

  By the way, for frameless frames (including some frames without frames) such as so-called two-point or nyroll, the shape of the target lens shape (including some deformations) is different from metal frames with frames all around. ). For this reason, some spectacle lens ordering / ordering systems are configured so that the ordering side apparatus can cope with the deformation of the lens shape of the spectacle lens (see, for example, Patent Documents 1 to 3). Specifically, as described in Patent Documents 1 to 3, in the ordering side device, while displaying an image of the original target lens shape before deformation on a display screen such as a display, the target lens shape on the display screen There are some which are configured to transmit the data related to the target lens shape after the deformation to the order receiving side device.

  However, in the above-described conventional system, the following problems occur when the lens shape of the spectacle lens is deformed.

When deforming the lens shape of the spectacle lens, it is necessary to avoid the occurrence of defects in the lens layout of the spectacle lens that is processed with the deformed lens shape. A lens layout defect is a defect in the relationship between the lens shape of an eyeglass lens and the shape layout of the raw lens on which it is based. Specifically, in the case of a progressive lens, the distance portion or the near portion is a ball. It refers to problems such as cutting due to mold deformation, or problems such as the shape of a small ball being unnatural or not looking good in the case of a bifocal lens.
However, when deforming the lens shape of the spectacle lens in the conventional system, after the lens shape is determined, an inquiry is made to the order receiving device of the spectacle lens maker who orders the spectacle lens, so that the lens layout is obtained. It is designed to check whether or not a problem has occurred. In other words, in the conventional system, it is not possible to confirm whether or not a defect has occurred unless the lens layout after the target lens shape deformation depends on the result of an inquiry to the order receiving side device using the inquiry function of the ordering side device.
Therefore, in the conventional system, if there is a defect in the lens layout, the ordering side device calls the eyeglass lens shape image on the display screen and deforms the shape again, or the ordering side device Therefore, it is necessary to perform a change process (re-input process) to the type of the spectacle lens that does not occur.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the present embodiment, description will be made by dividing into items in the following order.
1. 1. Configuration example of the entire system 2. Example of functional configuration of ordering device 3. Order processing procedure 4. Effects of the present embodiment Modifications etc.

<1. System configuration example>
FIG. 1 is a block diagram showing an example of the overall configuration of a spectacle lens ordering system.
In the illustrated system configuration, a spectacle store 1 on the spectacle lens ordering side and a spectacle lens manufacturer processing center 2 on the spectacle lens processing side are connected via a communication line 3 such as the Internet. ing. In the example shown in the figure, a single spectacle store 1 is shown, but actually, a plurality of spectacle stores 1 are connected to the processing center 2 via the communication line 3.

The spectacle store 1 is provided with an ordering device 11. The ordering apparatus 11 includes a computer unit 11a having a calculation processing function as a computer, which includes a combination of a CPU (Central Processing Unit), a RAM (Random Access Memory), an HDD (Hard disk drive), and the like, a keyboard, a mouse, a touch panel, and the like. An operation unit 11b that inputs information to the computer unit 11a, and a display unit 11c that includes a display device and displays an image in accordance with an instruction from the computer unit 11a. The computer unit 11a is connected to the communication line 3 through a router or the like (not shown), and is configured to exchange data with other devices through the communication line 3.
In the spectacle store 1, a tracer 12 is connected to the ordering side device 11. The tracer 12 measures the frame shape along the frame groove of the lens frame of the spectacle frame and the target lens shape (dummy lens or pattern) attached to the spectacle frame, and the measurement result is sent to the computer unit. This is input to 11a. Based on the measurement result of the tracer 12, at least the target lens shape of the original lens is specified. A known tracer 12 can be used.

In the processing center 2, an order receiving side device 21 is arranged. The order receiving side device 21 is configured to have a function as a computer, and is connected to the communication line 3 via a router or the like (not shown), whereby another device (for example, an ordering side device) on the communication line 3 is connected. 11) can exchange data.
In the processing center 2, the target processing apparatus 21 is connected to a target lens processing apparatus 22 and a database 23 via a communication line 24 such as a LAN (Local Area Network).
The lens shape processing device 22 follows an instruction from the order receiving side device 21 and is an unprocessed lens that is the basis of a spectacle lens (that is, an uncut lens that is not processed into a spectacle frame shape and generally has a round shape). ) Is processed into a specified target lens shape. As the target lens shape processing device 22, a known device can be used.
The database 23 stores and accumulates information (for example, information on the type and model number of the raw lens) that may be necessary for processing the raw lens into a spectacle lens.
In addition to the order receiving side device 21, the target lens shape processing device 22 and the database 23, the processing center 2 is provided with processing devices such as a curve generator and a polishing machine, other terminal computers, etc. (all not shown). May be.

  In addition, a data server 4 configured to be accessible from the ordering side device 11 of the spectacle store 1 is disposed on the communication line 3. The data server 4 stores and accumulates “eyeglass lens information” which will be described in detail later. Note that the location of the data server 4 is not particularly limited. That is, if the “glasses lens information” is stored and stored and can be accessed from the ordering apparatus 11, the data server 4 is stored in the database 23 in the processing center 2 or other database (not shown). It can be considered to have a function.

In the eyeglass lens ordering and receiving system configured as described above, the store clerk operating the operation unit 11b of the ordering side device 11 at the eyeglass store 1 can select the lens shape (lens shape) or lens prescription desired by the customer. When data relating to a value or the like is input, the computer unit 11a of the ordering side apparatus 11 transmits the input data to the order receiving side apparatus 21 through the communication line 3 to place an order for the spectacle lens. On the processing center 2 side, when the order receiving side apparatus 21 receives an order from the ordering side apparatus 11, the target lens processing apparatus 22 and the like follow the ordering contents (that is, the contents of transmission data from the ordering side apparatus 11). The outer diameter shape of the raw lens on which the spectacle lens is based is processed into a specified target lens shape.
However, in ordering apparatus 11, when ordering spectacle lenses, the shape of the target lens shape on the display screen is deformed while displaying the shape of the original target lens shape before deformation on the display unit 11c as will be described in detail later. Can be done.

<2. Example of functional configuration of ordering device>
Next, a functional configuration of the ordering apparatus 11 in the spectacle lens ordering system will be described.

As described above, the ordering device 11 can cope with the deformation of the lens shape of the spectacle lens when ordering the spectacle lens. However, even when dealing with the deformation of the lens shape of the spectacle lens, unlike the conventional system, it should be possible to speed up the ordering process of the spectacle lens without causing a problem of the lens layout. .
In this regard, the inventor of the present application has intensively studied. As a result, if the lens shape of the spectacle lens can be changed while checking the shape layout of the raw lens so as not to cause a problem with the lens layout, it corresponds to the deformation of the spectacle lens shape. In addition, the idea was that it would be possible to speed up the ordering process for the spectacle lens. Further, after earnest examination, if the manufacturer of the raw lens that is the basis of the spectacle lens, it is noted that the information regarding the shape layout of the raw lens is retained, and the information is placed on the ordering device 11. If a mechanism that does not exist in the conventional system is introduced, such as displaying the image on the display unit 11c and making it visible, the shape of the eyeglass lens can be changed while checking the shape layout of the raw lens. It came to the knowledge that it was possible to do.
The order-side device 11 in the spectacle lens ordering / ordering system of the present embodiment has been devised based on the above-described new knowledge by the present inventor, and the computer unit 11a has a functional configuration as described below. .

FIG. 2 is a block diagram illustrating an example of a functional configuration of the ordering apparatus 11 in the spectacle lens ordering system.
As shown in the figure, the computer unit 11a of the ordering apparatus 11 includes an input receiving unit 51, an information acquiring unit 52, a display control unit 53, a target lens deforming unit 54, a data correcting unit 55, an order processing unit 56, and a data storage. It is configured to function as the means 57.

The input receiving unit 51 receives information input from the operation unit 11 b of the ordering apparatus 11 and information input from the tracer 12. Information input from the operation unit 11b includes lens designation information 61 and layout information 62, and information input from the tracer 12 includes spectacle frame information 63.
The lens designation information 61 is information necessary for specifying the raw lens that is the basis of the spectacle lens desired by the customer, and specifically, information for specifying the manufacturer name and lens model number of the raw lens (details will be described later). Corresponding to a part of “glasses lens information”), a prescription value of the lens, and the like. The prescription value is a power value of a spectacle lens that is treated to suit the visual environment of the customer, specifically, the spherical power of the left and right eyes, cylindrical (astigmatism) power, cylindrical (astigmatism) axial power, prism power, This is the degree of participation. The lens designation information 61 may be any information that can identify an unprocessed lens, and may include items other than those listed here.
The layout information 62 is information for adjusting the optical center of the lens to the position of the wearer's pupil, and indicates the position of the fitting point (eye point) with reference to the geometric center (frame center) of the spectacle frame. . Specifically, it is composed of items such as PD (distance between pupils for distance), NPD (distance between pupils for near distance), SEG (segment ball position), EP (eye point), and FPD (distance between geometric centers). .
The spectacle frame information 63 is data for specifying the shape of the original target lens shape before the deformation of the spectacle lens, and includes mounting hole data (hole position, hole diameter, hole depth, etc.) in the two-point frame, and groove data ( Groove width, groove depth, fixed location data in the case of target lens deformation, etc.), non-deformable areas (or deformable areas) in the nyroll frame, and the like. The eyeglass frame information 63 is not input from the tracer 12, but is acquired by the input receiving unit 51 from a storage device provided in the ordering side device 11, a server device existing on the communication line 3, or the like. It doesn't matter.

The information acquisition means 52 is one of new functions that the conventional system does not have, and accesses the data server 4 through the communication line 3 and acquires the spectacle lens information 64 from the data server 4.
The spectacle lens information 64 is information on the raw lens that is the basis of the spectacle lens. Specifically, information that specifies the manufacturer name and lens model number of the raw lens, and the lens type (single focal point) of the raw lens. Information that specifies the lens, progressive lens, bifocal (multifocal), color, coat type, etc.), lens material (glass, plastic, etc.), etc.
Further, the spectacle lens information 64 includes information regarding the shape layout of the unprocessed lens. The “shape layout” here refers to the outer shape of the raw lens, the position of the eye point, the disposition of the distance and near portions in the case of a progressive lens, the disposition of small balls in the case of a bifocal lens, etc. Say. As long as such a shape layout can be specified, the data format of the spectacle lens information 64 is not particularly limited, and any data format may be used.

The display control means 53 creates an image of the display screen for ordering the eyeglass lens and displays the created image on the display unit 11c. In addition to a GUI (Graphical User Interface) image for performing an ordering operation, the created image by the display control means 53 includes an image about the lens shape of the eyeglass lens.
Furthermore, the display control means 53 is a new function that the conventional system does not have, and a function that causes the display unit 11c to display an image of the shape layout of the raw lens that is the basis of the spectacle lens together with the lens shape of the spectacle lens. have. What is necessary is just to produce | generate the image of the shape layout of an unprocessed lens based on the content specified from the spectacle lens information 64 which the information acquisition means 52 acquired.
The display image of the eyeglass lens shape and the raw lens shape layout by the display control means 53 will be described in detail in “3.

  The lens shape deforming means 54 is a function for coping with the deformation of the lens shape of the spectacle lens. More specifically, the target lens shape of the spectacle lens displayed on the display unit 11c by the display control unit 53 is deformed to a shape desired by the customer on the display screen while following the operation content of the operation unit 11b. Is. The method for deforming the target lens shape is not particularly limited. For example, even if it is performed by numerical input as in Patent Documents 1 and 2, a dedicated method on the screen as in Patent Document 3 is used. You may perform using a deformation | transformation tool.

  The data correction means 55 is one of new functions that the conventional system does not have, and accepts a change (re-input) of the lens designation information 61 or the layout information 62 on the display screen by the display unit 11c. More specifically, in the state where the display control means 53 displays an image of the lens shape of the spectacle lens and the shape layout of the raw lens on which the spectacle lens is based on the display unit 11c, the lens designation information 61 or layout information of the spectacle lens is displayed. For at least one of 62, the change (re-input) of the content already accepted by the input accepting means 51 is accepted. When the data correction unit 55 accepts the data change, the display control unit 53 causes the display unit 11c to redisplay the target lens shape and the raw lens shape layout specified by the changed data content. It has become.

  When the order contents of the spectacle lens are confirmed, the order processing means 56 transmits the order contents (that is, the lens designation information 61, layout information 62, spectacle frame information 63, etc. after confirmation) to the order receiving side device 21 through the communication line 3. By doing so, the eyeglass lens is ordered. When ordering spectacle lenses, if there is a change in the shape of the target lens by the target lens deformation means 54 or a change in the data content by the data correction means 55, the change or change is reflected, The order processing means 56 places an order to the order-receiving device 21.

  The data storage means 57 stores and holds the order contents by the order processing means 56 as the ordered data 65 in association with identification data such as the ordering customer, the order processing, the ordered eyeglass lens, etc. as necessary. Is. The ordered data 65 to be stored and stored includes data on the target lens shape of the spectacle lens after the target lens shape is deformed by the target lens deforming means 54. That is, when the target lens shape is deformed, the data storage means 57 stores and holds the data regarding the target lens shape of the spectacle lens in association with the spectacle lens identification data.

  Among these, each means 51-56 other than the data storage means 57 is implement | achieved when the CPU of the said computer part 11a runs the predetermined program installed in HDD etc. of the computer part 11a. That is, the function as each means 51-56 in the computer unit 11a of the ordering apparatus 11 can be realized by a predetermined program (eyeglass lens ordering program) that causes the computer unit 11a to function as each means 51-56. . In this case, the spectacle lens ordering program may be provided through the communication line 3 prior to installation in the HDD of the computer unit 11a, or stored in a storage medium readable by the computer unit 11a. May be provided.

  The data storage means 57 can be realized by using a part of the storage area in the HDD or the like of the computer unit 11a. However, the data storage unit 57 does not necessarily have to be included in the computer unit 11a of the ordering apparatus 11, and the computer unit 11a includes a communication unit (not shown) that enables access to the data storage unit 57. If so, it may be arranged in a device different from the ordering device 11 (for example, a part of the storage area in the data server 4). Further, when the data storage means 57 inherent in the computer unit 11a and the data storage means 57 of another device that can be accessed via the communication means coexist, the computer functions as a setting means for selecting a data storage destination. The part 11a may be provided. In the case described above, the communication unit and the setting unit are realized by executing a predetermined program in the computer unit 11a, like the above-described units 51 to 56.

<3. Order processing procedure>
Next, the procedure of the eyeglass lens ordering / receiving process in the eyeglass lens ordering / ordering system configured as described above will be described. Here, the ordering process of the spectacle lens in the ordering side apparatus 11 will be described, and the other processes are not different from the conventional system, and the description thereof will be omitted.

(Outline of ordering process for eyeglass lenses)
FIG. 3 is a flowchart showing an outline of the procedure of the ordering process of the spectacle lens in the ordering side apparatus 11 in the spectacle lens ordering / ordering system.

  When ordering a spectacle lens from the spectacle store 1 to the processing center 2, in the order side apparatus 11 in the spectacle store 1, first, the display control means 53 of the computer unit 11a displays a GUI image for performing the ordering operation. It is displayed on the part 11c.

  When ordering spectacle lenses, the store clerk of the spectacle store 1 operates the operation unit 11b while referring to the GUI image of the display unit 11c in response to a request from the customer, and includes various items including lens designation information 61 and layout information 62. Enter information. When these various types of information are input, the computer unit 11a receives the various types of information input by the input receiving unit 51, and temporarily stores at least the lens designation information 61 and the layout information 62 using a storage device such as a RAM or HDD. (Step 101, the following step is abbreviated as “S”).

  In the spectacle store 1, the store clerk operates the tracer 12 to measure the target lens shape of the original lens attached to the spectacle frame desired by the customer. The measurement result is input from the tracer 12 to the computer unit 11a of the ordering apparatus 11 as the spectacle frame information 63 of the spectacle lens to be ordered. When there is data input from the tracer 12, the computer unit 11a receives the input spectacle frame information 63 by the input receiving means 51, and uses a storage device such as a RAM or HDD as in the case of the lens designation information 61 and the like. Is temporarily held (S102). If the spectacle frame information 63 of the spectacle lens to be ordered can be acquired from the storage device of the ordering side apparatus 11 or the server apparatus existing on the communication line 3, the input receiving means 51 from these data existing locations. It is also conceivable to capture the spectacle frame information 63. That is, in this case, the measurement operation by the tracer 12 is unnecessary.

  After the input accepting means 51 accepts the lens designation information 61, the layout information 62, and the spectacle frame information 63, then, is an operation requesting that the eyeglass lens bead shape be deformed in the operation unit 11b? The display control means 53 of the computer unit 11a determines whether or not (S103). This is to cope with the deformation of the target lens shape (including partial deformation) for frameless frames (including some without frames) such as two-point and nyroll. Whether or not there is a request for deforming the target lens shape can be determined by whether or not a predetermined operation for requesting target lens deformation has been performed in the operation unit 11b.

  If there is a request to deform the target lens shape (Yes in S103), then in the computer unit 11a, the information acquisition unit 52 accesses the data server 4 through the communication line 3, and the data server 4 sends the spectacle lens. Information 64 is acquired (S104). At this time, based on the lens designation information 61 of the spectacle lens to be ordered, the information acquisition unit 52 identifies the raw lens that is the basis of the spectacle lens, that is, the model number from the content of the lens designation information 61. For an unprocessed lens, spectacle lens information 64 regarding the shape layout is acquired.

  Thereafter, in the computer unit 11 a, the display control unit 53 is specified from the eyeglass lens shape specified from the spectacle frame information 63 received by the input receiving unit 51 and the spectacle lens information 64 acquired by the information acquisition unit 52. The shape layout of the unprocessed lens is displayed on the display unit 11c (S105). At this time, the display control unit 53 causes the display unit 11c to display an image by matching the shape layout of the raw lens that is the basis of the spectacle lens with the target lens shape of the spectacle lens. Here, “matching” with the lens shape of the spectacle lens means that the respective images are combined in a plane while maintaining the positional relationship between the spectacle lens and the raw lens. That is, the display control unit 53 grasps the positional relationship between the spectacle lens and the unprocessed lens specified from the layout information 62 received by the input receiving unit 51, and the eyeglass lens shape image according to the positional relationship. Are combined with the image of the shape layout of the unprocessed lens so that the respective images can be visually recognized on the same screen.

  When the display unit 11c displays an image while following the instruction from the display control unit 53, in the computer unit 11a, the target lens shape deforming unit 54 executes the target lens shape deforming process (S106). Specifically, for example, the lens shape of the spectacle lens displayed by the display unit 11c is deformed while following the operation content such as numerical input of the deformation amount in the operation unit 11b or graphic deformation using a dedicated deformation tool. . Thereby, on the display screen of the display part 11c, the lens shape of the spectacle lens is deformed from the shape of the original lens to the shape desired by the customer.

  However, at this time, the shape layout of the unprocessed lens is displayed on the display screen of the display unit 11c together with the lens shape of the spectacle lens. Therefore, in the process of deforming the lens shape of the spectacle lens, the operator of the operation unit 11b performs an operation for the deformation process while referring to the shape layout of the unprocessed lens displayed as an image on the display unit 11c. be able to. That is, since the target lens shape can be deformed while referring to the shape layout of the unprocessed lens, the deformed target lens shape can be determined so as not to cause a problem in the lens layout. More specifically, in the case of a progressive lens, the distance portion or the near portion is cut due to the lens shape deformation (displaced from the spectacle frame), or in the case of a bifocal lens, a small ball. It is possible to prevent problems such as unnatural shape or unsatisfactory appearance. Further, since the shape layout includes the outer shape of the unprocessed lens, an insufficient diameter error that may be caused by the lens shape change can also be confirmed.

By the way, when deforming the lens shape of the spectacle lens, as described above, referring to the shape layout of the unprocessed lens, it is possible to determine the deformed lens shape that does not cause a problem in the lens layout. it can. However, the deformed target lens shape determined in this way is not necessarily the target target lens shape. In other words, it may be necessary to correct the shape layout of the unprocessed lens in order to make the deformed target lens shape coincide with the shape desired by the customer without causing any trouble in the lens layout. The same applies to a case where a diameter shortage error of an unprocessed lens occurs. In addition, in the “correction of the shape layout of the raw lens” here, in addition to changing the raw lens itself to another shape layout (that is, correction of the lens designation information 61), It also includes correcting the positional relationship with the processing lens (that is, correcting the layout information 62).
However, in the conventional system, the shape layout cannot be confirmed while the target lens is deformed, and the lens is not changed at this stage. That is, after confirming the target lens shape deformation, an order is actually made using the “inquiry” of the order processing means, and the final layout can be confirmed only by the result. For this reason, in the conventional system, when the shape layout of the unprocessed lens is corrected, all the processes are performed again from the beginning, and the operator may feel annoyed. In addition, this makes it difficult to realize a quick ordering process, which may cause the customer to feel dissatisfied.
Therefore, the ordering apparatus 11 in the eyeglass lens ordering / order receiving system of the present embodiment performs the processing described below so that the operation can be continued on the target lens shape deformation screen without returning to the information input screen.

  When the target lens deforming means 54 deforms the target lens shape, thereafter, the display control means 53 of the computer unit 11a monitors whether or not a predetermined operation for confirming the deformation process has been performed on the operation unit 11b (S107). ). If there is no predetermined operation for confirming the deformation process (no in S107), then the display control means 53 of the computer unit 11a operates the predetermined operation for requesting correction of the shape layout of the unprocessed lens. It is monitored whether or not it is performed by the unit 11b (S108).

  As a result, if there is no predetermined operation for requesting layout correction (no in S108), the display control means 53 and the target lens deforming means 54 of the computer unit 11a continue the process for deforming the target lens shape as it is. (S106 to S108).

On the other hand, when there is a predetermined operation for requesting layout correction (Yes in S108), the display control means 53 of the computer unit 11a displays a GUI image for layout correction on the display unit 11c. More specifically, on the display screen of the display unit 11c displaying the lens shape of the spectacle lens and the shape layout of the unprocessed lens, a lens specification is specified as a GUI image for layout correction together with these display images. A GUI image for inputting at least one of the information 61 and the layout information 62, preferably both of them is displayed as an image.
The display control means 53 may display a GUI image for correcting the layout from the beginning of the image display of the eyeglass lens shape and the raw lens shape layout. In that case, it may be determined that there has been an operation for requesting layout correction when data is input to the data input field of the GUI image.

  When the lens designation information 61 or the layout information 62 is input to the GUI image data input field by the operation unit 11b, the data correction means 55 changes (re-inputs) the lens designation information 61 or the layout information 62 in the computer unit 11a. ) Is received (S109). That is, the data correction means 55 has already been input with respect to at least one of the lens designation information 61 or the layout information 62 in a state where the eyeglass lens shape and the raw lens shape layout are displayed on the display unit 11c. Change (re-input) is accepted.

  When the data correction unit 55 accepts such data change (re-input), the computer 11a newly acquires the spectacle lens information 64 specified from the changed data by the information acquisition unit 52 (S104). Then, the display control means 53 causes the display unit 11c to display an image of the lens shape of the spectacle lens specified from the post-change data and the shape layout of the raw lens specified from the newly acquired spectacle lens information 64. (S105). Thereafter, the computer unit 11a repeats the series of processes described above again (S106 to S109).

  That is, when the data change (re-input) as described above is performed, the lens shape of the spectacle lens and the shape layout of the unprocessed lens specified by the changed data content are redisplayed on the target lens deformation screen. Will be. Therefore, even if it is necessary to correct the shape layout of the raw lens in order to obtain the target lens shape desired by the customer, the operator of the operation unit 11b can change the target lens shape without returning to the information input screen at the beginning of the process. Operations can be performed continuously from the screen. Then, by correcting the shape layout of the unprocessed lens, it is possible to realize that the deformed target lens shape matches the shape desired by the customer without causing any trouble in the lens layout. In addition, even when an unprocessed lens diameter shortage error occurs, it is possible to eliminate the diameter shortage error by correcting the shape layout of the unprocessed lens.

  After execution of a series of processes as described above, when there is a predetermined operation for confirming the deformation process of the target lens shape (yes in S107), or when there is no request for changing the target lens shape from the beginning. (No in S103) In the computer unit 11a, the confirmed order contents (that is, the lens designation information 61, layout information 62, spectacle frame information 63, etc. after confirmation) are received by the order processing means 56 through the communication line 3 and the order receiving side device 21. By sending to, the eyeglass lens is ordered (S110).

  When the order processing means 56 performs the ordering process for the spectacle lens, the data storage means 57 stores and holds the ordered data 65 in the computer unit 11a as necessary. Here, “as necessary” means that it is not always necessary to store and hold all the contents of the order. That is, the data storage means 57 may be any one that stores and holds at least a part of the order contents by the order processing means 56 as the ordered data 65. Specifically, when the target lens shape is deformed, it is conceivable to store and retain the data regarding the target lens shape of the spectacle lens in association with the identification data of the spectacle lens. . However, the data storage unit 57 may store and hold all the order contents.

As described above, if the data storage unit 57 has a function of storing and holding data (deformation history) about the deformed target lens shape, the data storage unit 57 is used when the same spectacle lens is ordered thereafter. It becomes possible to place the order while reusing the stored data.
In addition, since the data on the lens shape of the spectacle lens after deformation is stored and retained in association with the identification data of the spectacle lens, the relationship between the lens shape and the lens layout is not limited to storage as a simple change history. It can be said that the information will be retained. Therefore, it is possible not only to refer to the change history when ordering the spectacle lens, but also to use the stored data in the data storage means 57 as a guideline when deforming the target lens shape. Specifically, with this type of unprocessed lens, it is possible to make a determination that it is possible to perform up to this degree of target lens deformation with reference to the stored data in the data storage means 57.

(Specific example of eyeglass lens ordering process)
Next, the spectacle lens ordering process according to the above-described series of procedures will be described in more detail with reference to a specific example of a display image on the display unit 11c. Here, a process relating to the deformation of the lens shape of the spectacle lens, which is a characteristic process in the ordering apparatus 11 in the spectacle lens ordering system of the present embodiment, will be mainly described with a specific example.

  4 to 11 are explanatory diagrams schematically showing specific examples of display images on the display unit in the process of ordering spectacle lenses in the order-side device 11 of the spectacle lens ordering / ordering system.

  In the process of ordering eyeglass lenses, in the ordering side apparatus 11, when the input receiving unit 51 receives the eyeglass frame information 63, the eyeglass lens shape specified from the eyeglass frame information 63 is displayed from the display control unit 53. The display unit 11c displays an image while following the instruction. As a result, as shown in FIG. 4, an eyeglass-shaped planar view image 71 a of the spectacle lens is displayed on the display screen of the display unit 11 c. At this time, the top-view image and the side-view image of the target lens shape may be displayed together with the target lens-shaped planar view image 71a on the display screen. Further, on the display screen, in addition to the planar shape image 71a of the target lens shape, numerical information about the target lens shape (for example, A size value indicating the size in the horizontal direction, B indicating the size in the vertical direction). The size value, the perimeter value of the outer shape of the target lens shape, etc.) may be displayed together. It is also assumed that operation buttons necessary for continuing the ordering process are also displayed on the display screen. The image of the operation button displayed here includes an image 71b of a “lens deformation button” for requesting that the operator deform the target lens shape.

  When the target lens shape deformation button 71b is clicked on this display screen, in the ordering side apparatus 11, the information acquisition unit 52 acquires the spectacle lens information 64 and the target lens shape deformation unit 54 is activated. Then, the display unit 11 c shifts the image display content on the display screen to a screen for deforming the target lens shape (hereinafter, simply referred to as “target lens shape screen”) while following the instruction from the display control unit 53.

On the target lens shape deformation screen, as shown in FIG. 5, a planar image 72a of the target lens shape of one of the right (R) or left (L) eyeglass lenses is displayed, and the target lens shape plane is displayed. Together with the visual image 72a, a planar image 72b of the shape layout of the raw lens specified from the spectacle lens information 64 acquired by the information acquisition means 52 is displayed. These planar images 72a and 72b are displayed in a state where the respective images are combined in a planar manner while maintaining the positional relationship between the spectacle lens and the unprocessed lens. That is, the positional relationship between the spectacle lens and the raw lens specified from the layout information 62 received by the input receiving means 51, more specifically, the fitting point (eye) of the raw lens with respect to the geometric center (boxing center) of the spectacle lens. Point) While grasping the positional relationship (that is, the vertical and horizontal separation distances between the respective positions specified from the PD and EP of the layout information 62), the planar view of the spectacle lens according to the positional relationship In a state where the image 72a and the planar image 72b of the unprocessed lens are combined, the respective planar images 72a and 72b are displayed so as to be visible on the same target lens deformation screen.
On the target lens shape deformation screen, various information and operation buttons necessary for deforming the target lens shape of the spectacle lens in addition to the combined planar view images 72a and 72b. It shall be displayed. The operation buttons include right (R) and left (L) display switching buttons (not shown).

  The planar view image 72b of the unprocessed lens varies depending on the lens type (single focus lens, progressive lens, bifocal lens, etc.). Accordingly, the composition of the planar images 72a and 72b also differs depending on the lens type of the unprocessed lens.

For example, when the raw lens is a single focus lens, as shown in FIG. 6A, the outer shape 73a of the raw lens is displayed together with the lens shape of the spectacle lens, and the boxing of the spectacle lens is performed. The center position 73b, the eye point position 73c of the unprocessed lens, the fitting information between the boxing center and the eye point (for example, the respective separation distances), and the like are displayed.
Further, for example, when the raw lens is a progressive lens, in addition to the display content when it is a single focus lens, as shown in FIG. 6B, the distance portion 73d and the near portion in the progressive lens The position, range, etc. of 73e are displayed.
Further, for example, when the raw lens is a bifocal lens, in addition to the display content when the raw lens is a single focal lens, as shown in FIG. 6C, the shape and arrangement of the small balls 73f in the bifocal lens. The position, range, etc. are displayed.

  Then, on the target lens shape deformation screen, the target lens shape of the spectacle lens is deformed while following the operation content of the operation unit 11b. The target lens shape is deformed by a deformation method selected by the operator on the target lens shape deformation screen.

For example, “enlargement / reduction deformation” is selected as a deformation method on the target lens deformation screen, and a part to be further deformed (for example, the entire target lens shape, A size, B size, B lower side, etc.) is specified. If the numerical value of the size to be enlarged / reduced is specified in mm (for example, see FIG. 5), the target lens deforming unit 54 displays the image of the “enlarge / reduce button” on the target lens shape deformation screen ( However, using a click (not shown) as a trigger, the target lens shape after deformation according to the specified content is obtained by a predetermined calculation, and the calculation result is notified to the display control means 53. The predetermined calculation for obtaining the target lens shape after the deformation may be performed using a publicly known technique, and the detailed description thereof is omitted here.
When there is a notification from the target lens shape deforming means 54, the display control means 53, as shown in FIG. The display unit 11c is instructed to display the planar view image 74b. Thereby, the operator who referred the display content on the target lens shape deformation screen can grasp how much the target target lens shape is deformed compared to the target lens shape of the original lens. 7A shows a case where the entire lens shape is deformed, FIG. 7B shows a case where the A size of the target lens shape is changed, and FIG. 7C shows a case where the target lens shape is B. FIG. 7D shows a case where the size is changed, and FIG. 7D shows a case where the B size is changed only on the lower side of the target lens shape.
At this time, on the target lens deformation screen, in addition to the target lens shape planar images 74a and 74b, a planar image regarding the shape layout of the unprocessed lens (not shown in FIG. 7) is also displayed. It is displayed. Therefore, the operator who refers to the display content on the target lens shape deformation screen can easily determine whether or not the lens layout has a defect with respect to the target target lens shape.

In addition, for example, “on demand” is selected as a deformation method on the target lens deformation screen, a portion to be further deformed (for example, upper deformation or lower deformation) is specified, and the deformation range is the left side of the range. If the angle and the right point are specified by an angle value (see, for example, FIG. 5), the target lens deforming unit 54 displays an image of a “deformation start button” on the target lens shape deformation screen (not shown). The display control means 53 is notified that the graphic deformation using the dedicated deformation tool is to be started with the click of as a trigger.
When there is a notification from the target lens shape deforming means 54, the display control means 53 makes a display mode different from the target lens shape of the original lens for the line segment of the specified range that constitutes the outer shape of the target lens shape (for example, display color) Instructions are given to the display unit 11c. Then, it is possible to realize the transformation of the line segments having different display modes by the operation of the operation unit 11b (for example, an operation of dragging one point on the line segment with the mouse). As for the graphic processing at this time (how to change the entire designated range), since a known graphic processing technique may be used, the detailed description thereof is omitted here.
When such an operation for deforming a figure is performed, as shown in FIG. 8, on the target lens deformation screen, the target lens-shaped planar view image 75a is indicated by a line segment having a different display mode. The deformed target lens shape planar view image 75b is displayed in an overlapping manner. Therefore, the operator who refers to the display content on the target lens deformation screen can grasp how much the target target lens shape is deformed compared to the target lens shape of the original lens.
At this time, on the target lens shape deformation screen, in addition to the target lens shape planar images 75a and 75b, a planar image regarding the shape layout of the unprocessed lens (not shown in FIG. 8) is also displayed. It is displayed. Therefore, the operator who refers to the display content on the target lens shape deformation screen can easily determine whether or not the lens layout has a defect with respect to the target target lens shape.

  Then, when the operator who refers to the display content on the target lens deformation screen determines that the target target lens shape is obtained and the lens layout is not defective, on the target lens deformation screen, the deformation process is performed. As a predetermined operation for confirming, “Confirm button” image 72c on the target lens shape deformation screen shown in FIG. 5 is clicked.

  On the other hand, when the target lens shape desired by the customer is not obtained, or when there is a problem with the lens layout, for example, when “enlargement / reduction deformation” is selected as the deformation method of the target lens shape Then, by re-entering a new numerical value, the target lens shape is redone. In addition, for example, when “on demand” is selected as a method for deforming the target lens shape, reset the deformed image, and then execute the operation for deforming the shape again to deform the target lens shape. Try again.

  In addition, here, when the deformation of the target lens shape is performed by inputting a numerical value with “enlargement / reduction deformation” selected as the method, or by using a dedicated tool on the target lens deformation screen when “on demand” is selected. Although the case where it carries out was mentioned as an example, it is not limited to these deformation | transformation methods, These may be used together or you may use a completely different deformation | transformation method.

  By the way, even after deforming the target lens shape, it may not always be possible to achieve both the customer's desired target lens shape and the lens layout so as not to cause a problem. Absent. In other words, it may be necessary to correct the shape layout of the unprocessed lens in order to make the deformed target lens shape coincide with the shape desired by the customer without causing any trouble in the lens layout. For such a case, the ordering apparatus 11 can perform the following processing.

  In the ordering apparatus 11, when there is a predetermined operation for requesting layout correction, a GUI image for layout correction is displayed and the data correction means 55 is activated. As a predetermined operation for requesting layout correction, there is a click on an image (not shown) of a “layout correction button” on the target lens deformation screen, but other operations (for example, operation of a predetermined key on the keyboard) are included. It doesn't matter.

  The GUI image for layout correction may be displayed on the target lens deformation screen as shown in FIG. 9, for example, or the front screen of the target lens deformation screen as shown in FIG. You may return to the target lens shape display screen and overlap the display screen. In addition to these screens, for example, a pop-up screen may be displayed by opening it in a separate window.

  Hereinafter, the display content of a GUI image for layout correction will be described with a specific example. The GUI image for layout correction is provided with a data input field for inputting at least one of the lens designation information 61 and the layout information 62, preferably both of them.

  Specifically, as in the GUI image shown in FIG. 9, for example, a data input field 76a for inputting numerical values for RPD (one eye pupil distance) and EP (eye point) as a data input field of the layout information 62. There is something with. Furthermore, since numerical values are input for the RPD, an image 76b of the “R / L switching button” of the display image for the spectacle lens is also displayed. In addition to these, input items such as “lens name” and “lens diameter” may be configured to be input on the GUI image.

Also, in the processing center 2 where the eyeglass lenses are ordered, for example, for progressive lenses, a double-sided design tailored to the customer to design an optimal aspheric surface for each order and give each lens optimal performance There is something that can handle. Further, for example, some bifocal lenses can cope with the amount of centering and height specification at the center of the ball.
In this case, if the GUI image is, for example, a progressive lens of double-sided design, as shown in FIG. 10, numerical values for PD (distance between pupils for distance) and EP (eyepoint) are used as data input fields of layout information 62. In addition to the data input field 77a for inputting, to input numerical values for "progressive band length", "inset amount (also referred to as inset amount)" and "close work target distance" required for progressive design It is conceivable to provide a data input field 77b. “Progressive band length” is a distance from a distance fitting point that looks far away to a near eye point that looks close, and corresponds to the length of the distance that has changed from the power that looks far away to the power that looks close. The “inset amount” is a difference between PD (distance between distance pupils) and NPD (distance between near pupils). “Near work target distance” is, for example, a distance from an eye to a book when reading a book. Similarly, for example, in the case of a bifocal lens, it is conceivable that “the height of the small ball” or “the amount of inward centering of the small ball” is provided in the data input column 77b (not shown).

  Note that the data input column of the GUI image mentioned here is merely a specific example. Therefore, the GUI image for correcting the layout may be provided with data input fields for other items in addition to the data input fields listed here or instead of the data input fields listed here. I do not care.

  By displaying the GUI image as described above, the order-side apparatus 11 does not return to the information input screen at the beginning of the process without returning to the information input screen even when it is necessary to correct the shape layout of the unprocessed lens. It becomes possible to cope with the correction.

  Thereafter, for example, when an image 77c of a “layout confirmation button” as shown in FIG. 10 is clicked, the data correction unit 55 determines that data input for layout correction is completed, and changes (re-inputs) data. Accept. Then, on the display screen by the display unit 11c, the lens shape of the spectacle lens and the shape layout of the unprocessed lens are displayed according to the contents specified from the changed data.

  Therefore, the ordering apparatus 11 can correct the shape layout of the unprocessed lens without returning to the information input screen at the beginning of the process, thereby preventing a problem in the lens layout. It becomes feasible to match the target lens shape with the shape desired by the customer. In addition, even when an unprocessed lens diameter shortage error occurs, it is possible to eliminate the diameter shortage error by correcting the shape layout of the unprocessed lens.

  In this way, after the deformed target lens shape is matched with the shape desired by the customer without causing any trouble in the lens layout, a predetermined operation for confirming the target lens shape deformation process is performed. The confirmed order contents (that is, the lens designation information 61 after confirmation, layout information 62, spectacle frame information 63, etc.) are transmitted to the order receiving side device 21, whereby the spectacle lens is ordered. The predetermined operation for confirming the target lens shape deformation process includes a click on the image 77d of the “registration button” displayed on the screen shown in FIG. 10, but other operations (for example, predetermined keys on the keyboard) It may be the operation).

  Further, when there is a predetermined operation for confirming the deformation processing of the target lens shape as described above, this is used as a trigger, and data (deformation history) about the target lens shape after the deformation is stored in the data storage means 57. It is also conceivable to store the information in the memory. Further, only when there is a predetermined operation for storing and holding the deformation history regardless of the above-described operation, the data storage unit 57 stores and holds the data about the target lens shape (deformation history). It is also possible.

  At this time, the data storage means 57 does not stop storing data as a simple change history, but also stores and holds the relationship between the target lens shape and the lens layout. Therefore, it is possible not only to refer to the change history when ordering the spectacle lens, but also to use the stored data in the data storage means 57 as a guideline when deforming the target lens shape.

  Specifically, when there is a predetermined operation (for example, operation of a predetermined key on the keyboard) in the operation unit 11b in the ordering side device 11, as shown in FIG. 11, for example, the contents stored on the display screen by the display unit 11c Displays information on the list in a list format. Then, when the check box 78a of the data that the operator wants to refer to is clicked, and when the “decision button” image 78b is clicked, the specified data is read from the data storage means 57, and the spectacle lens specified by the data is read. The target lens shape and the raw lens shape layout are displayed on the display screen of the display unit 11c. This makes it possible to use the stored data as described above.

<4. Effects of this embodiment>
According to the spectacle lens ordering system, spectacle lens ordering program, and spectacle lens ordering method described in the present embodiment, the following effects can be obtained.

  According to the present embodiment, when deforming the lens shape of the spectacle lens, the shape layout of the raw lens specified from the spectacle lens information 64 acquired by the information acquisition unit 52 is combined with the target lens shape to display the display unit 11c. Therefore, the target lens shape can be deformed while confirming the shape layout of the unprocessed lens so as not to cause a problem of the lens layout. Specifically, for example, in the case of a progressive lens, the distance portion or the near portion is cut due to the lens shape deformation, or in the case of a bifocal lens, the shape of the small ball is unnatural. In addition, it is possible to prevent problems such as poor appearance. In addition, a diameter shortage error that may occur due to the target lens change can also be confirmed. Therefore, even when dealing with the deformation of the lens shape of the spectacle lens, the spectacle lens is compared with the case of the conventional system that requires an inquiry to the order-receiving device 21 to confirm the lens layout after the lens shape deformation. Order processing can be performed quickly, and customer dissatisfaction about the time required for order processing, operator inconvenience, and the like can be eliminated.

  Further, according to the present embodiment, the data correction means 55 sets the lens designation information 61 and the layout information 62 while the eyeglass lens shape and the raw lens shape layout are displayed on the display unit 11c. Accept change (re-input) for at least one. Therefore, even if it is determined that the shape layout of the raw lens needs to be corrected as a result of the operator referring to the contents of the image display, the layout correction can be handled without returning to the information input screen at the beginning of the process. As a result, it is possible to realize that the deformed target lens shape matches the shape desired by the customer while preventing the lens layout from being defective. In addition, even when an unprocessed lens diameter shortage error occurs, it is possible to eliminate the diameter shortage error by correcting the shape layout of the unprocessed lens. In other words, as a result of judging the suitability of the eyeglass lens shape deformation based on the shape layout of the raw lens, all processing is restarted from the beginning even if it is necessary to cope with the layout correction. Therefore, the operator does not feel annoyance. In addition, this makes it possible to realize a quick ordering process, so that the customer does not feel dissatisfied.

  Further, according to the present embodiment, the data storage unit 57 stores and holds data (deformation history) regarding the target lens shape after deformation. Therefore, when the same spectacle lens is ordered after that, it becomes possible to place the order while reusing the stored data in the data storage means 57. This also contributes to the realization of a quick ordering process. Further, the data storage unit 57 stores and holds the relationship between the target lens shape and the lens layout as well as the storage and holding as a simple change history. Therefore, it is possible not only to refer to the change history when ordering the spectacle lens, but also to use the stored data in the data storage means 57 as a guideline when deforming the target lens shape. From these, it can be said that it is very convenient for the operator, the customer, and the like.

<5. Modified example>
While embodiments of the present invention have been described above, the above disclosure is intended to illustrate exemplary embodiments of the present invention. That is, the technical scope of the present invention is not limited to the above exemplary embodiment.

  For example, in the above-described embodiment, when correcting the shape layout of the raw lens, a case where “progressive band length” or the like is re-input for the progressive lens is given as a specific example. It is possible to cope with data correction. Such data correction may be performed when the shape layout of the raw lens needs to be corrected. That is, if correction of the shape layout of the unprocessed lens is unnecessary, data correction by the data correction means 55 is not an essential process.
