Description

Technical Field

[0001] This disclosure relates to the ordering device, ordering method and procedure. Background Technology

[0002] Tinted lenses are sometimes used as eyeglass lenses. Tinted lenses are mostly chosen for their fashion appeal, glare reduction, and blue light protection. Therefore, almost all orders specify the color and intensity of the tinted lenses to personal preference.

[0003] Tinted lenses are an important tool for improving the quality of life (QOL) for wearers with visual hypersensitivity or color weakness. From the perspective of improving the wearer's QOL, sometimes it is desirable to wear tinted lenses that match one's own visual characteristics rather than tinted lenses with a preferred color and intensity.

[0018] The present invention will be described below through embodiments, but these embodiments do not limit the invention as defined in the patent claims. Furthermore, not all combinations of the features described in the embodiments are necessary for the solutions provided by the invention.

[0019] Figure 1 This is a schematic structural diagram of the DIOS (Digitalized Optical Lens Ordering System) of this embodiment. Figure 1 As shown, the DIOS tinted lens ordering system includes an order management server 10 and multiple ordering devices 20.

[0020] The order management server 10 communicates with each of the multiple ordering devices 20 via a communication network NW. The order management server 10 sends and receives data with each of the multiple ordering devices 20 through this communication network NW. The communication network NW can be, for example, a wireless communication transmission path, a wired communication transmission path, or a combination of both. A wireless communication transmission path can be, for example, a wireless LAN (Local Area Network). The communication network NW can be any of the following: a mobile communication network (e.g., a mobile phone line network), a wireless packet communication network, the Internet, or a dedicated line, or a combination thereof. For example, the communication network NW can also use short-range wireless communication standards (e.g., ZigBee, Wi-Fi, or Bluetooth).

[0021] The order management server 10 is, for example, a server device managed by an eyewear manufacturer. The order management server receives order data for tinted lenses from the ordering device 20 via a communication network NW. These tinted lenses are used as eyeglass lenses. The order management server manages the order data for tinted lenses, for example, on a per-wearer basis. The order management server can also manage the order data for tinted lenses on a per-ordering device 20 basis. For example, when the order management server 10 receives order data for tinted lenses, it displays the order data on its display screen.

[0022] The order taker confirms the order data displayed on the order management server 10 and commissions a factory to manufacture the tinted lenses shown in the order data. For example, if the tinted lenses shown in the order data are in stock, the order taker arranges for their delivery.

[0023] The ordering device 20 communicates with the order management server 10 via the communication network NW, thereby sending and receiving data with the order management server 10. The ordering device 20 is an information processing device, such as a mobile phone, smartphone, tablet terminal, personal computer, or wearable device. The ordering device 20 can be a fixed device or a portable device. Furthermore, the ordering device 20 can be installed in an optical shop, or it can be a device owned by the wearer. That is, the ordering device 20 can be a device owned by an eyewear manufacturer or an optical shop, or it can be a device owned by an individual.

[0024] Figure 2 This is an example of the hardware structure of the ordering device 20 in this embodiment. For example... Figure 2 As shown, the ordering device 20 includes a communication interface (hereinafter referred to as "communication I / F") 40, a display device 41, an input device 42, a storage device 43, and a processor 44.

[0025] The communication I / F40 can communicate with the order management server 10. The display device 41 displays various data. The display device 41 is, for example, a liquid crystal display or an organic EL (Electroluminescence) display. For example, the display device 41 may also include a touch panel-type display screen.

[0026] The input device 42 can be operated by the user and inputs data corresponding to the user's operation to the processor 44. The input device 42 includes, for example, a touch panel, a touch display, hardware keys such as a keyboard, pointing devices such as a mouse, and a microphone (for sound-based operation input).

[0027] Storage device 43 may include, for example, non-volatile or volatile semiconductor memory (e.g., RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable Read Only Memory), EEPROM (Electrically Erasable Programmable Read Only Memory)).

[0028] An application for ordering tinted lenses (hereinafter referred to as the "ordering application") is installed on the storage device 43. In addition, data processed by the ordering application and the like is stored in the storage device 43.

[0029] The ordering application (APP) can also be provided by a computer-readable recording medium, i.e., a computer-readable storage medium. The ordering application is read from the computer-readable storage medium, installed in storage device 43 (an example of which is also a computer-readable storage medium), and executed by processor 44. The ordering application can also be downloaded from an external device via a wired or wireless communication network. That is, the ordering application can also be provided via a computer-readable storage medium or an electronic communication line such as a network.

[0030] Examples of computer-readable media include electronic storage media, magnetic storage media, optical storage media, electromagnetic storage media, semiconductor storage media, etc. More specific examples of computer-readable media include floppy disks (registered trademark), diskettes, hard disks, random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM or flash memory), electrically erasable programmable read-only memory (EEPROM), static random access memory (SRAM), optical disc read-only memory (CD-ROM), digital versatile optical disc (DVD), Blu-ray (RTM) optical discs, memory sticks, integrated circuit cards, etc.

[0031] Processor 44 is, for example, one or more processors including CPU (Central Processing Unit), MPU (Microprocessing Unit), GPU (Graphics Processing Unit), and FPGA (Field-Programmable Gate Array).

[0032] The processor 44 controls various processes for ordering tinted lenses by executing the ordering application APP stored in the storage device 43. The processor 44 receives various data from the input device 42 or the communication I / F 40. The processor 44 performs some calculation based on the received data and displays the result on the display device 41. The processor 44 can also send data received from the input device 42 to the order management server 10 via the communication I / F 40.

[0033] Figure 3 This is a functional block diagram of the processor 44 in this embodiment. Figure 3 As shown, the processor 44 includes a processing unit 51 and an output unit 52. The processing unit 51 and the output unit 52 can be implemented, for example, by the processor 44 executing a subscription application APP stored in the storage device 43.

[0034] The processing unit 51 controls the display on the display device 41. The processing unit 51 displays the setting screen 100 on the display device 41. The setting screen 100 is a screen for inputting the data required to order tinted lenses.

[0035] Figure 4 This diagram illustrates an example of the setting screen 100 in this embodiment. The setting screen 100 includes a first display area 60, a second display area 61, a third display area 62, and a confirmation icon 63.

[0036] In the first display area 60, multiple input fields 70 corresponding to various wavelengths are displayed. Each input field 70 contains data representing the transmittance of the ordered item for the corresponding wavelength (hereinafter referred to as "transmittance data"). The ordered item is the tinted lens ordered by the user (e.g., a wearer) using the ordering device 20. Furthermore, the transmittance data can be any data that directly or indirectly represents transmittance; it can be a numerical value of transmittance or data other than a numerical value. Additionally, the transmittance data can also be the cutoff rate of the corresponding wavelength.

[0037] Multiple bands simply means two or more bands. Figure 4 In the example shown, as an example of multiple bands, three bands are defined: a first band, a second band, and a third band. Specifically, the first band, the second band, and the third band are obtained by dividing the visible light band into three bands. To distinguish the three input fields 70 corresponding to each of the three bands, the input field 70 corresponding to the first band is sometimes described as "first input field 70a", the input field 70 corresponding to the second band is described as "second input field 70b", and the input field 70 corresponding to the third band is described as "third input field 70c".

[0038] For example, the visible light spectrum can be divided into three bands, with the lowest band designated as the first band, the highest band as the third band, and the middle band as the second band. The first, second, and third bands can also be obtained by dividing the visible light spectrum into three equal parts. Alternatively, the first, second, and third bands can be divided according to certain rules. For instance, the first, second, and third bands can be obtained by dividing the visible light spectrum based on the spectral sensitivity (spectral absorption characteristics) of the three types of cone cells in the human retina (S cone cells, M cone cells, and L cone cells). The spectral sensitivity of these three types of cone cells is different for each type.

[0039] For example, the first band is set based on the spectral sensitivity of S-cone cells. S-cone cells are cones with higher spectral sensitivity to the short-wavelength region of the visible light band compared to the other two types of cone cells. In other words, S-cone cells are cones that respond to the short-wavelength region. S-cone cells have a peak sensitivity wavelength around 430 nm in the short-wavelength region. That is, the short-wavelength region is a wavelength band encompassing 430 nm. The first band is set based on this short-wavelength region. The first band can be set as the short-wavelength region or as a range encompassing the short-wavelength region. As an example, the first band is above 380 nm and below 500 nm.

[0040] For example, the third band is set based on the spectral sensitivity of L-cone cells. L-cone cells are cones with high spectral sensitivity to the long wavelength region of the visible light band compared to the other two types of cone cells. In other words, L-cone cells are cones that respond to the long wavelength region. L-cone cells have a peak sensitivity wavelength around 560 nm in the long wavelength region, and this sensitivity region overlaps with the sensitivity region of M-cones described later. In addition, if it is around 630 nm, the sensitivity of M-cones becomes quite low, mainly affecting L-cones. Therefore, as an example of this embodiment, the long wavelength region is set to a wavelength band including 630 nm. The third band is set based on this long wavelength region. The third band can be set as the long wavelength region or as a range including the long wavelength region. As an example, the third band is 600 nm or more and less than 780 nm.

[0041] For example, the second band is set based on the spectral sensitivity of M-cone cells. M-cone cells are cones with higher spectral sensitivity in the mid-wavelength region of the visible light spectrum compared to the other two types of cone cells. In other words, M-cone cells are cones that respond to the mid-wavelength region. M-cone cells have a peak sensitivity wavelength around 530 nm in the mid-wavelength region. That is, the mid-wavelength region is a wavelength band encompassing 530 nm. The second band is set based on this mid-wavelength region. The second band can be set as the mid-wavelength region or as a range encompassing the mid-wavelength region. As an example, the second band is above 500 nm and below 600 nm.

[0042] like Figure 4 As shown, on the setting screen 100, a first input field 70a corresponding to the first wavelength, a second input field 70b corresponding to the second wavelength, and a third input field 70c corresponding to the third wavelength are provided in the first display area 60. Furthermore, on the setting screen 100, information indicating the first wavelength (e.g., "transmittance in the short wavelength region") is displayed near the first input field 70a. Additionally, on the setting screen 100, information indicating the second wavelength (e.g., "transmittance in the mid-wavelength region") is displayed near the second input field 70b. Furthermore, on the setting screen 100, information indicating the third wavelength (e.g., "transmittance in the long wavelength region") is displayed near the third input field 70c.

[0043] In the first input field 70a, the transmittance data (hereinafter referred to as "first transmittance data") that the wearer wishes to set as the ordered object in the first band is entered. In the second input field 70b, the transmittance data (hereinafter referred to as "second transmittance data") that the wearer wishes to set as the ordered object in the second band is entered. In the third input field 70c, the transmittance data (hereinafter referred to as "third transmittance data") that the wearer wishes to set as the ordered object in the third band is entered. By entering transmittance data in each of the first input field 70a, the second input field 70b, and the third input field 70c, the transmittance of the ordered object in the first band, the second band, and each band of the second band is specified. Furthermore, as a method of entering transmittance data in input field 70, the transmittance data can be entered directly in input field 70, or the transmittance data can be entered by selecting any transmittance data from multiple candidate values ​​from the drop-down menu.

[0044] The transmittance data entered into each input field 70 can also be set to be entered at intervals of 2% to 20% from the lower limit to the upper limit of the input range. For example, multiple candidate values ​​in the drop-down menu are values ​​spaced X% (2% ≤ X ≤ 20%) from the lower limit to the upper limit of the input range.

[0045] The predicted visual transmittance of the ordered object is displayed in the second display area 61. Predicted visual transmittance is an indicator of the degree of visible light transmission; it is also known as visible light transmittance. When transmittance data is entered into the first input field 70a, the second input field 70b, and the third input field 70c, the predicted visual transmittance of the ordered object is displayed in the second display area 61. When transmittance data is entered into the first input field 70a, the second input field 70b, and the third input field 70c, the predicted hue of the ordered object is displayed in the third display area 62.

[0046] The processing unit 51 accepts transmittance data input into each input field 70. Accepting transmittance data includes acquiring transmittance data. For example, when any transmittance data is input into the first input field 70a, the processing unit 51 accepts that transmittance data as the first transmittance data. That is, the transmittance data input into the first input field 70a is set as the first transmittance data.

[0047] For example, when arbitrary transmittance data is entered into the second input field 70b, the processing unit 51 accepts that transmittance data as the second transmittance data. That is, the transmittance data entered into the second input field 70b is set as the second transmittance data.

[0048] For example, when arbitrary transmittance data is input into the third input field 70c, the processing unit 51 accepts the transmittance data as the third transmittance data. That is, the transmittance data input into the third input field 70c is set as the third transmittance data.

[0049] Furthermore, inputting arbitrary transmittance data into input field 70 includes inputting arbitrary transmittance data into input field 70 when it is empty, as well as changing transmittance data already input into input field 70. When changing transmittance data already input into input field 70, processing unit 51 accepts the changed transmittance data, i.e., the newly input transmittance data. For example, if a user changes the value of input field 70a from the first value to a second value using input device 42 while a first value is input into the first input field 70a, processing unit 51 accepts the second value as the first transmittance data. That is, processing unit 51 sets the second value, rather than the first value, as the first transmittance data.

[0050] Upon receiving the first transmittance data, the second transmittance data, and the third transmittance data, the processing unit 51 calculates the predicted visual transmittance based on the received first transmittance data, second transmittance data, and third transmittance data. Then, as... Figure 5As shown, the processing unit 51 displays the predicted visual transmittance on the second display area 61. Furthermore, when the first transmittance data, the second transmittance data, and the third transmittance data are received, the processing unit 51... Figure 5 As shown, the color tone of the order object corresponding to the received first transmittance data, second transmittance data and third transmittance data is displayed in the third display area 62.

[0051] When the confirmation icon 63 is operated via the input device 42, the processing unit 51 determines the value input to the first input field 70a as first transmittance data, the value input to the second input field 70b as second transmittance data, and the value input to the third input field 70c as third transmittance data. Here, "operating" the confirmation icon 63 refers to, for example, clicking the confirmation icon 63 or performing a touch operation on it. A touch operation includes, for example, a tap, a swipe, or a flick.

[0052] For example, if no information is entered in at least one of the first input field 70a, the second input field 70b, and the third input field 70c, the processing unit 51 may invalidate the confirmation icon 63. Alternatively, the processing unit 51 may enable the confirmation icon 63 if information is entered in all of the input fields 70a, 70b, and 70c. Furthermore, the processing unit 51 may also enable the confirmation icon 63 if information is entered in all of the input fields 70a, 70b, and 70c and a predetermined condition is met.

[0053] For example, the processing unit 51 may enable the confirmation icon 63 after displaying the predicted visual transmittance and hue of the ordered object on the setting screen 100. Furthermore, if the transmittance data entered in the input field 70 is changed, the processing unit 51 will display the predicted visual transmittance and hue corresponding to the changed transmittance data on the setting screen 100. In this case, the processing unit 51 may also disable the confirmation icon 63 during the period from when the transmittance data is changed until the predicted visual transmittance and hue corresponding to the changed transmittance data are displayed on the setting screen 100.

[0054] Output unit 52 outputs the order data received by processing unit 51 to order management server 10 via communication I / F 40. That is, output unit 52 outputs order data containing transmittance data for each of multiple wavelengths of the tinted lens to order management server 10 via communication I / F 40. For example, when confirmation icon 63 is activated, output unit 52 outputs the order data to order management server 10 via communication I / F 40. Figure 3In the setup screen 100 shown, the output unit 52 outputs, for example, order data including first transmittance data, second transmittance data and third transmittance data to the order management server 10 via the communication I / F 40.

[0055] More specifically, the output unit 52 outputs the following order data, namely, order data that associates the transmittance data input to the input field 70 with the corresponding band of the input field 70, to the order management server 10 via the communication I / F 40. Figure 3 In the example shown, output unit 52 outputs the following order data to order management server 10: the order data includes first association data that associates first transmittance data with data representing a first band, second association data that associates second transmittance data with data representing a second band, and third association data that associates third transmittance data with data representing a third band. Furthermore, the order data only needs to include the first, second, and third association data, but may also include other data (e.g., user ID or delivery deadline).

[0056] The following describes the method for ordering the tinted lenses according to this embodiment. Figure 6 This is a flowchart of the method for ordering tinted lenses according to this embodiment.

[0057] In the tinted lens ordering method of this embodiment, an operator operates the ordering device 20 to order tinted lenses. Here, if the ordering device 20 is installed in an optical shop, the operator can be a shop employee or a customer visiting the shop. If the operator is a shop employee, the employee operates the ordering device 20 while listening to the requirements of a wearer who is considering purchasing tinted lenses, thereby ordering tinted lenses that match the wearer's visual characteristics.

[0058] Alternatively, if the ordering device 20 is a communication terminal (e.g., mobile phone, smartphone, tablet, or personal computer) owned by an individual (e.g., a wearer), the operator is the user of the portable terminal (e.g., the wearer). In this case, the communication terminal functions as the ordering device 20 by installing an ordering application APP on it.

[0059] The following explanation will be based on the scenario where the operator is a wearer considering purchasing tinted lenses. To order tinted lenses, the operator uses the ordering device 20 to activate the ordering application (APP) (step S101).

[0060] The operator operates the ordering device 20, which has already launched the ordering application APP, causing the setting screen 100 to be displayed on the information terminal 2 (step S102). That is, when the input device 42 receives an operation to display the setting screen 100, the ordering device 20 displays the setting screen 100 on the display device 41. Furthermore, the ordering device 20 can also display the setting screen 100 on the display device 41 at a timed launch of the ordering application APP. In other words, the display of the setting screen 100 in step S102 does not necessarily require operator intervention.

[0061] The operator operates the input device 42 and inputs the desired transmittance data into each of the first input field 70a, the second input field 70b, and the third input field 70c on the setting screen 100. When transmittance data is input into each of the first input field 70a, the second input field 70b, and the third input field 70c, the ordering device 20 accepts the transmittance data input into each input field 70 (step S103).

[0062] Specifically, the processing unit 51 receives the transmittance data input into the first input field 70a as first transmittance data. The processing unit 51 receives the transmittance data input into the second input field 70b as second transmittance data. The processing unit 51 receives the transmittance data input into the third input field 70c as third transmittance data.

[0063] When the first transmittance data, second transmittance data, and third transmittance data are received, the processing unit 51 displays the predicted visual transmittance and hue of the order object corresponding to the first transmittance data, second transmittance data, and third transmittance data on the setting screen 100 (step S104). The operator confirms the predicted visual transmittance and hue displayed on the setting screen 100, and if there are no problems, operates the confirmation icon 63. In addition, the operator confirms the predicted visual transmittance and hue displayed on the setting screen 100, and if there are any problems, changes the value of at least one of the input fields 70, namely the first input field 70a, the second input field 70b, and the third input field 70c. Whenever the value of the input field 70 is changed, the ordering device 20 performs the processing steps S103 and S104.

[0064] When the confirmation icon 63 is activated, the output unit 52 sends the order data to the order management server 10 (step S105). This order data includes first association data that associates first transmittance data with data representing a first band, second association data that associates second transmittance data with data representing a second band, and third association data that associates third transmittance data with data representing a third band. The order for the tinted lens is completed upon successful transmission of the order data to the order management server 10.

[0065] In this way, the operator can order tinted lenses by specifying the transmittance of multiple bands separately using the ordering device 20. That is, the wearer can order tinted lenses that match their own visual characteristics, thus improving the wearer's QOL (Quality of Life).

[0066] Currently, there are two main methods for selecting tinted lenses: the first method and the second method. The first method involves choosing a product from a pre-defined product line that matches the wearer's preferences in terms of color and intensity. In this method, the wearer specifies the color and intensity when ordering. The second method, known as sample tinting, involves sending the target lens to the lens manufacturer to have a replica made with the same color and intensity.

[0067] Both the first and second selection methods are not significantly different from ordering tinted lenses based on appearance, color, and intensity. On the other hand, for wearers with hypersensitivity or color weakness, tinted lenses are an important tool for improving their QOL (Quality of Life). Ideally, for improving the QOL of wearers with hypersensitivity or color weakness, tinted lenses should match their visual characteristics rather than their preferred color and intensity. However, both the first and second selection methods prioritize appearance, color, and intensity, making it currently impossible to order tinted lenses that perfectly match the wearer's visual characteristics.

[0068] The ordering device 20 of this embodiment receives transmittance data for each of multiple wavelengths of tinted lenses and outputs order data including the received transmittance data for each wavelength to the order management server 10. With this structure, it is possible to order tinted lenses that match the wearer's visual characteristics.

[0069] Furthermore, visual hypersensitivity or color weakness is believed to be caused by the sensitivity of the three types of cone cells (S cone cells, M cone cells, and L cone cells) on the retina being higher or lower than normal. Based on this background, the ordering device 20 can specify the transmittance of three bands corresponding to the spectral sensitivity of the three types of cone cells when ordering tinted lenses. This allows for the ordering of tinted lenses that better suit the wearer's visual characteristics. In other words, when ordering tinted lenses, the wearer can specify the intensity of stimulation (cone stimulation level) received by each of the three types of cone cells according to their own visual characteristics.

[0070] Furthermore, in this embodiment, three wavelengths are exemplified as multiple wavelengths used to specify the transmittance of the tinted lens, but this is not a limitation. For example, there could also be four wavelengths. In this case, for example, the visible light could be divided into four equal parts. As an example, the visible light wavelengths are set to 380nm to 780nm, the first wavelength is set to 380nm or more and less than 480nm, the second wavelength is set to 480nm or more and less than 580nm, the third wavelength is set to 580nm or more and less than 680nm, and the fourth wavelength is set to 680nm or more and less than 780nm.

[0071] The execution order of the actions, processes, steps, and stages in the apparatus, system, program, and method shown in the claims, specification, and drawings is not specifically indicated as "earlier" or "prior to." Furthermore, it should be noted that the execution order of the processes can be arbitrary as long as the output of a previous process is not used in a subsequent process. Regarding the flow of actions in the claims, specification, and drawings, even if terms such as "firstly" or "secondly" are used for convenience, it does not mean that they must be performed in that order. Additionally, wherever permitted by law, the disclosures of Japanese Patent Application No. 2023-209261 and all documents cited in this specification are incorporated into this document.
