According to the optometry control program and the optometry system according to the present disclosure, the optometry can be performed more smoothly.

The subjective optometry system exemplified in the present disclosure includes a subjective optometry device and a first information processing device. The optometry device has a correction optical system that changes the optical characteristics of the target luminous flux presented to the optometry, and a target display unit that presents the target to the subject, and is aware of the optical characteristics of the subject. Used to measure to. The first information processing device is an information processing device connected to a subjective eye examination device (hereinafter, the first information processing device may be referred to as a "connection device"). The optometry control program according to the present disclosure includes a self-optometry application program. The self-optometry application program is a program for realizing an application (self-optometry application) that automatically advances optometry based on an answer input by a subject.

The self-optometry application program is executed by the control unit of the first information processing device, and the self-optometry progress step, the answer acquisition step, the correction value storage step, and the self-optometry assist step are executed by the first information processing device. To. In the self-optometry progression step, the first information processing apparatus performs the action of presenting the optotype to the subject, at least based on (that is, according to the progress procedure) the automatically progressing procedure of the self-optometry. A plurality of presentation instruction signals to be instructed are sequentially output to the subjective optometry device. In the self-optometry progress step, the first information processing apparatus controls the correction optical system and the optotype presenting unit in order to execute a plurality of test items based on the self-eye examination progress procedure that is automatically progressed. You may. In the answer acquisition step, the first information processing apparatus acquires the answer input by the subject who visually recognizes the presented optotype. In the correction value storage step, the first information processing apparatus is acquired based on the answer acquired in the answer acquisition step and the optical characteristics of the optotype and the optotype luminous flux presented by the subjective optometry apparatus at the time of answer acquisition. The correction value of the optical characteristics of the eye to be inspected is memorized. In the self-optometry assisting step, the first information processing apparatus executes an assisting operation to assist the progress of the self-optometry when a problem occurs in the progress of the self-optometry.

According to the subjective optometry system according to the present disclosure, by executing the self-optometry application, the subject's optometry can be appropriately performed even if the examiner does not proceed with the optometry. Further, when a problem occurs in the progress of the self-optometry, an auxiliary operation for assisting the progress of the self-optometry is executed. That is, a function that assists the progress of self-optometry is incorporated in the function of the self-optometry application. Therefore, for example, while the self-optometry application is being executed, at least one of the assistive actions of the self-optometry by the advice from the examiner or the like is executed. Therefore, the subjective optometry is appropriately performed while the burden on the examiner is reduced.

Various devices can be used for the first information processing device that executes the optometry control program. For example, a personal computer (hereinafter referred to as "PC") may be used as the first information processing device. Further, a server, a mobile terminal, a smartphone, or the like may be used as the first information processing device.

Further, the first information processing device may be configured by combining a plurality of devices. For example, the first information processing device may be composed of a device such as a personal computer and a dedicated controller including a controller and a storage device. Of course, the dedicated controller itself may be provided with a function as a device such as a personal computer equipped with a CPU, and may be configured as a first information processing device.

In addition, a storage device for storing the optometry control program can be appropriately selected. For example, the eye examination control program may be stored in a storage device built in the first information processing device, or may be stored in a storage device that can be attached to and detached from the first information processing device. The optometry control program may be stored in the storage device built in the dedicated controller described above. Further, the optometry control program may be stored in a plurality of storage devices.

In the self-optometry assist step, when the status of the self-optometry being performed meets a predetermined condition, or when an instruction to execute the assisted action is input, an assisted action for assisting the progress of the self-optometry is executed. May be done. In this case, when the subject cannot perform the self-optometry, the assisting operation of the self-optometry is appropriately performed.

The conditions for the self-optometry situation when performing the auxiliary movement can be selected as appropriate. For example, the control unit may determine that the execution condition of the auxiliary operation is satisfied when the predetermined time elapses without inputting the answer from the subject. Further, the control unit may determine that the execution condition of the auxiliary operation is satisfied when the answer input by the subject is inappropriate. The method of determining whether or not the answer is inappropriate can be appropriately selected. For example, if the input answer does not meet the predetermined answer conditions (for example, if an answer different from the answer candidate requested from the subject is input, the control unit will give the same answer. If the answers are entered more than the specified number of times in a row, or if more answers are entered than the number of answers requested from the subject), it is judged that the entered answers are inappropriate. You may.

The assisting action performed in the self-optometry assisting step may include a calling action to call the examiner. In this case, the examiner is called when there is a problem in the progress of the self-optometry, so that the subsequent optometry is appropriately performed.

The self-optometry assisting step may include a manual optometry step that outputs a presentation instruction signal for advancing at least a part of the optometry procedure to a subjective optometry device in response to an instruction input by the examiner. In this case, the examiner can manually proceed with the examination or the like in which a problem occurs among the progress procedures that were planned to be advanced by the self-optometry. Therefore, optometry for the subject is more appropriately assisted.

The self-optometry assisting step may include a correction value correction step that corrects at least one or more of the correction values stored by the self-optometry according to an instruction input by the examiner. In this case, for example, even if there is a correction value in which the measurement by the self-optometry fails, the correction value is corrected by the judgment of the examiner. Therefore, the optometry for the subject proceeds smoothly.

The self-optometry assisting step may include a test omission step that omits at least part of the progress procedure according to instructions entered by the examiner. In this case, the examiner can omit the procedure determined to be unnecessary from the predetermined progress procedures. Therefore, the optometry for the subject proceeds smoothly.

The method of inputting instructions by the examiner in order to omit at least a part of the progress procedure can be appropriately selected. For example, the examiner may input to the first information processing apparatus a test selection instruction to be omitted from a plurality of tests executed according to the progress procedure. In this case, the control unit of the first information processing apparatus may omit the selected test from the progress procedure. Further, the examiner may input the timing for resuming the once stopped self-optometry to the first information processing apparatus as a timing after the procedure for omitting the procedure. In this case, the control unit of the first information processing apparatus may omit some steps by restarting the self-optometry from the input timing.

The self-optometry assist step may include a proxy response acquisition step. In the proxy response acquisition step, the control unit inputs the answer of the subject who visually recognizes the presented optotype when the optotype is presented to the subject in the self-optometry progress step according to the progress procedure. Get according to the instructions given. In this case, the examiner listens to the answer from the subject who visually recognizes the optotype in the process of presenting the optotype to the subject in order according to the procedure of self-optometry, and inputs the heard answer by himself / herself. can do. Therefore, even if the subject does not know the answer method in the self-optometry, the examiner can appropriately assist the self-optometry by inputting the answer heard from the subject. can.

The self-optometry assisting step may include a continuous resumption step of resuming the temporarily stopped self-optometry from the procedure following the procedure for which the optometry has already been completed (for example, a completed test, etc.). In this case, the self-optometry is restarted from the procedure following the already completed procedure among the progress procedures. Therefore, even after the assistance of the self-optometry is completed, the continuation of the self-optometry is appropriately performed according to the progress procedure.

The self-optometry assisting step may include a designated resumption step of resuming the temporarily stopped self-optometry from a procedure designated by the examiner (for example, a designated test, etc.) among the progress procedures. In this case, the examiner can restart the self-optometry from the procedure specified by the examiner when the problem that occurred during the self-optometry is solved. Therefore, it is possible to prevent the burden on the examiner for assisting the optometry from increasing excessively.

The procedure for proceeding with self-optometry may define a plurality of tests (examinations) executed for the subject and an execution order of the plurality of tests. In the self-optometry progression step, multiple tests may be performed in sequence according to the progression procedure. In this case, multiple tests on the eye to be inspected will proceed appropriately and automatically. Further, the examiner can appropriately assist a test that is determined to require assistance (for example, a test in which a good correction value is not obtained by self-optometry) among a plurality of tests.

The self-optometry assisting step may include a procedure display step for displaying the progress procedure on the display device. The display device may be located at a base where the examiner stands by, may be located at a base different from the base where the subjective optometry device is located, or may be located at a base where the subjective optometry device is located. They may be located at the same base. In the designated restart step, the input of the designated instruction of the procedure for restarting the self-optometry (hereinafter referred to as “restart procedure”) may be accepted on the progress procedure displayed by the display device. In this case, the examiner can specify a resumption procedure for resuming the self-optometry while appropriately grasping the details of the progress procedure, the progress status, and the like by the displayed progress procedure.

The specific method for accepting the input of the restart procedure on the displayed progress procedure can be appropriately selected. For example, a touch panel may be provided in the display area of the display device. In this case, the control unit may process the displayed progress procedure corresponding to the position where the touch panel is operated (for example, a specific test or the like) as a restart procedure designated by the examiner. Further, a mouse or the like for moving the pointer within the display area of the display device may be provided. In this case, the control unit may process the procedure corresponding to the position of the pointer among the displayed progress procedures as the restart procedure designated by the examiner.

In addition, the control unit controls the procedure being performed at that time, the procedure being performed when a problem occurs in the progress, etc., among the entire progress procedure (for example, a plurality of tests included in the progress procedure). At least one of the above may be displayed on the progress procedure. In this case, the examiner can appropriately grasp the progress of the self-optometry by the displayed progress procedure.

As described above, restarting the once stopped self-optometry has various merits. For example, in the cross-cylinder test, which is one of the tests performed by the subjective optometry system, two point clouds are presented to the subject. However, if the relative position between the inspection window of the corrective optical system and the eye to be inspected is displaced, the subject may be able to see only one of the two point clouds. In this case, the subject cannot perform self-optometry. However, according to the subjective optometry system according to the present disclosure, the examiner gives advice to adjust the position of the optometry object with respect to the examination window while the self-optometry is temporarily stopped, and the cross-cylinder test is performed. After assisting the progression, the subject's independent self-optometry can be resumed. As described above, when the self-optometry once stopped is restarted, a useful effect can be obtained for both the examiner and the subject.

The self-eye examination assisting step may be executed in response to an instruction input to a second information processing device, which is another information processing device connected to the first information processing device via a network. In this case, even if the examiner is located in a remote location different from the subject's location, the examiner can appropriately perform self-optometry by the subject from a remote location by inputting an instruction to the second information processing device. Can be assisted.

When a problem occurs in the progress of self-optometry (for example, when an instruction to execute an auxiliary operation is input), the control unit of the first information processing apparatus issues an instruction to execute a calling operation to call the examiner. , May be output to the second information processing device. In this case, even if the examiner is located in a remote location different from the subject's location, the examiner can easily grasp that a problem has occurred in the progress of the self-optometry.

However, the self-optometry assisting step may be executed in response to an instruction directly input to the first information processing device (for example, an instruction input to the operation unit of the first information processing device). That is, the examiner at the place where the subjective optometry apparatus and the first information processing apparatus are installed may input an instruction for executing the self-optometry assist step. In this case, for example, the operation unit (controller for the examiner) of the first information processing device used for inputting an instruction from the examiner may be a dedicated controller provided in the subjective eye examination device, or a mouse. , A general-purpose user interface such as a tablet may be used.

Further, when the second information processing apparatus is used, the number of the second information processing apparatus may be one or two or more. Further, as the second information processing device, various devices (for example, a PC, a mobile terminal, a smartphone, etc.) can be used in the same manner as the first information processing device. The second information processing device may be already connected to the first information processing device when the self-optometry is executed, or may be connected to the first information processing device after a problem occurs in the self-optometry.

When the second information processing device is used, each control unit of the first information processing device and the second information processing device may at least input audio data (which may be both audio data and image data). A remote conversation step may be performed to assist the conversation between the examiner and the subject by transmitting and receiving each other. In this case, the optometry in a remote place can appropriately assist the self-optometry by grasping the situation of the subject by conversation.

As an example, the optometry control process of the present embodiment is executed in a state where communication (for example, remote access) of one or more second information processing devices 2B to the first information processing device 2A is established. However, the communication between the first information processing device 2A and the second information processing device 2B may be established during the execution of the optometry control process (for example, at the start of the self-optometry assist process shown in FIG. 4). Further, the communication method between the first information processing device 2A and the second information processing device 2B can also be appropriately selected. For example, remote access of the second information processing device 2B to the first information processing device 2A may be established by using the RAS (remote access service).

First, the CPU 21A acquires the optometry result by the objective method (S1). As an example, the first information processing device 2A of the present embodiment is an objective optometry device 3 (see FIG. 1) connected to the same subject via a LAN or a relay unit 19 or the like. Obtain the result of optometry. However, the CPU 21A may acquire objective optometry results for the same subject via, for example, a detachable memory, network 5, or the like. Further, the objective optometry result may be input by the user via the operation unit 34A or the like. If there is no objective optometry result for the same subject, the process of S1 may be omitted.

Next, the CPU 21A sets the procedure for proceeding with the self-optometry (S3). In the progress procedure display column 52 of FIG. 3, a part of an example of the progress procedure of the self-optometry used in the subjective optometry system 100 of the present embodiment (in FIG. 3, only the progress procedure for the right eye) is displayed. .. As illustrated in FIG. 3, the progress procedure used in the present embodiment defines a plurality of tests (several tests) performed on a subject and an execution order of the plurality of tests. As an example, in the progress procedure shown in FIG. 3, the R / G test (S), the cross cylinder-test (A), the cross cylinder-test (C), the R / G test, and the VA test are performed on the right eye of the subject. After that, an R / G test (S), a cross cylinder-test (A), a cross cylinder-test (C), an R / G test, and a VA test are performed on the left eye of the subject. In the R / G test (S), the spherical power of the eye to be inspected is measured. In the cross-cylinder test (A), the astigmatic axis angle of the eye to be inspected is measured. In the cross-cylinder test (C), the astigmatic power of the eye to be inspected is measured. Subsequent R / G tests confirm whether or not adjustment by the eye to be inspected worked in the performed test. The VA test measures the maximum visual acuity of the eye under test.

In S1, when the result of the objective optometry for the same subject is obtained, in S3, the result of the objective optometry (for example, the optical power measured for the same subject (for example, the ocular refractive power measured for the same subject). The procedure for self-optometry is set according to at least one of spherical power, astigmatic power, and astigmatic axis angle)). For example, in each test included in the progress procedure, the type and size of the optical element first arranged in the inspection window of the orthodontic optical system 11 and the optotype presented to the optotype presenting unit 16 are objective. It may be set according to the result of the optometry. If the astigmatism power obtained by the objective optometry is below the threshold value, a progress procedure is set in which the astigmatism test (for example, the cross-cylinder-test (A) and the cross-cylinder-test (C)) is omitted. You may. Further, in S1, when the result of the objective optometry is not acquired, the default progress procedure may be set in S3.

Next, the CPU 21A determines the next target display operation to be executed by the subjective optometry device 1 according to the progress procedure set in S3 and the progress status of the self-optometry, and causes the determined presentation operation to be executed. The presentation instruction signal (drive signal) is output to the subjective optometry device 1 (S5). Specifically, in S5 of the present embodiment, at least one of the optical element to be arranged in the inspection window of the correction optical system 11 and the optotype to be presented to the optotype presenting unit 16 is determined as the next presentation operation. .. A drive signal for at least one of the drive unit 12 and the drive unit 17 for executing the determined operation is transmitted to the subjective optometry device 1. When the CPU 21A transmits the drive signal to the subjective optometry device 1, the CPU 21A outputs a guidance voice according to the inspection content from the speaker 33A. Therefore, the subject can see the presented inspection target after appropriately grasping the inspection contents.

In the present embodiment, the drive signal is transmitted from the first information processing apparatus 2A to the

drive units

12 and 17 via the relay unit 19 (see FIG. 1) described above. Therefore, the signal transmitted from the first information processing apparatus 2A does not need to go through a dedicated controller or the like. Therefore, the processing of the signal by the dedicated controller or the like is omitted, and the optometry is executed more smoothly.

In the self-optometry, the subject grasps the inspection contents by the guidance voice, visually recognizes the inspection target presented by the subjective optometry apparatus 1, and inputs the answer of the visual inspection result to the first information processing apparatus 2A. do. As an example, in the present embodiment, the answer is input by operating the dedicated operation unit 34A suitable for inputting the answer of the subjective optometry by the subject. However, the answer may be input by a general operation unit 34A (for example, a mouse, a touch panel, a keyboard, etc.). Further, the answer may be input by the audio signal converted by the microphone 32A.

The CPU 21A determines whether or not the answer from the subject has been input (S7). When an answer is input (S7: YES), the input answer and the optically specific correction value (measured value) of the eye to be inspected are stored in the storage device 22A (S8). The correction values of the optical characteristics of the eye to be inspected are the answer input in S7, the optotype presented to the eye to be inspected when the answer was input, and the optical element arranged in the inspection window of the correction optical system 11. It is acquired based on the optical characteristics of (that is, the optical characteristics of the optometric luminous flux).

Next, if a series of self-optometry has not yet been completed (S9: NO), the process returns to S5 and the self-optometry is continued according to the progress procedure. As an example, in the VA test of the present embodiment, when the answer from the subject obtained in S7 is correct, the CPU 21A presents the visual acuity to the visual acuity display unit 16 last time. The next visual acuity presentation operation is determined so that the visual acuity value is one step higher than that of the visual acuity (for example, the visual acuity is one step smaller in size). Further, when the answer from the subject obtained in S7 is an incorrect answer, the CPU 21A sets the visual acuity value presented to the visual acuity display unit 16 to a visual acuity value one step lower than that of the visual acuity presented last time. The next visual acuity presentation operation is determined so that the visual acuity is an optotype (for example, an optotype whose size is one step larger). Further, the CPU 21A may determine the correction power of the optical element to be arranged in the inspection window of the correction optical system 11 and the correction power of the optical element to be arranged in the inspection window of the correction optical system 11 as the next target presentation operation.

When the processes of S7 to S9 are repeatedly executed and a series of self-optometry is successfully completed (S9: YES), the optometry control process ends as it is.

If no response from the subject has been entered (S7: NO), it is determined whether the self-optometry situation meets certain conditions that are likely to be inappropriate (S11). .. As an example, in the present embodiment, it is determined that the predetermined condition is satisfied when the predetermined time elapses without inputting the answer from the subject after the presentation instruction signal is transmitted in S5. In addition, if the answer entered by the subject is inappropriate (for example, if an answer different from the candidate answer requested by the subject is entered, the same answer will be repeated a predetermined number of times or more in succession. It is also determined that the predetermined condition is satisfied when the input is made, or when the number of answers requested from the subject is larger than the number of times the answer is input). When it is determined that the predetermined condition is satisfied (S11: YES), the self-optometry assisting process is executed (S13).

Further, when the answer from the subject is not input (S7: NO) and the condition of the self-optometry does not satisfy the condition (S11: NO), the CPU 21A performs the auxiliary operation of the self-optometry. It is determined whether or not the execution instruction has been input by the subject (S12). As an example, in the present embodiment, the subject gives an instruction to execute an auxiliary operation of self-optometry by operating a help button provided on a dedicated controller, a help button displayed on the display unit 35A, or the like. You can enter it. If it is not input (S12: NO), the process returns to S7. When the execution instruction of the auxiliary operation is input (S12: YES), the self-optometry assist process is executed (S13).

The details of the self-optometry assisting process will be described with reference to FIG. First, the CPU 21A executes the examiner call process (S21). As an example, in S21 of the present embodiment, the CPU 21A issues an examiner call instruction to one or more second information processing devices 2B for which remote access to the first information processing device 2A is established via the network 5. Send (S4). The examiner call instruction is an instruction to cause the second information processing apparatus 2B to execute the examiner's calling operation in order to request the examiner to assist the self-eye examination. The calling operation may be performed by at least one of methods such as audio output and image display, for example. By performing the calling operation, the user (inspector) of the second information processing apparatus 2B can appropriately grasp that the assist of self-optometry (remote assist in this embodiment) is necessary.

Next, the CPU 21A determines whether or not there is a response from the examiner who is the user of the second information processing apparatus 2B (S22). If there is no response from the examiner from any of the second information processing devices 2B (S22: NO), it is impossible for the examiner to assist the self-optometry, so the judgment of S22 is repeated and the standby state is reached. Will be. When the user of any of the second information processing devices 2B is in a state where self-optometry can be assisted and a response instruction is input to the second information processing device 2B (S22: YES), the process shifts to S23. ..

Next, the CPU 21A starts the call processing by starting the transmission / reception of voice data with the second information processing device 2B used by the examiner who assists the self-eye examination (S23). As a result, the auxiliary process of self-optometry described below is executed in a state where the subject and the examiner can talk. Specifically, the CPU 21A transmits the voice data input by the microphone 32A to the second information processing apparatus 2B. Further, the CPU 21A receives the voice data input to the second information processing apparatus 2B via the microphone 32B and outputs the voice data to the speaker 33A. The CPU 21A may send and receive image data to and from the second information processing device 2B together with the audio data. In this case, the CPU 21A may transmit the image data input by the camera 31A to the second information processing apparatus 2B. Further, the CPU 21A may receive the image data input to the second information processing apparatus 2B via the camera 32B and display it on the display unit 35A.

Next, the CPU 21A causes the self-optometry assist screen (see FIG. 3) to be displayed on the display unit 35B of the second information processing apparatus 2B used by the examiner who assists the self-optometry (S24). As shown in FIG. 3, the self-optometry assist screen in the present embodiment includes an operation image area 50 and a progress procedure display area 51.

In the operation image area 50, an operation image including information on the optical characteristics of the target luminous flux to be presented to the eye to be inspected is displayed. In the operation image of the present embodiment, the values related to the optical characteristics of the optotype luminous flux presented to the eye to be inspected are displayed for each type of optical characteristics. By operating various buttons and values on the operation image area 50 via an operation unit such as a touch panel or a mouse, the examiner can operate a plurality of types of optical characteristics (spherical power, cylindrical power, astigmatic axis angle, etc.). ), The value for the desired type can be specified. When the eye examination is properly performed, the correction value of the optical characteristics displayed on the operation image becomes the measured value of the optical characteristics of the eye to be inspected.

In the present embodiment, the progress procedure display area 51 is displayed not only on the display unit 35B connected to the second information processing device 2B but also on the display unit 35A connected to the first information processing device 2A. The progress procedure display area 51 of the present embodiment is provided with a progress procedure display field 52, an elapsed time display field 54, a left / right eye display field 55, a help button 56, and a top button 57. As described above, the progress procedure display field 52 displays the progress procedure set for the self-optometry during execution. In the example shown in FIG. 3, among the entire progress procedure (that is, a plurality of tests included in the progress procedure), the procedure being performed at that time is displayed on the progress procedure by the arrow 53 and the thick frame. The arrow.

The elapsed time display field 54 displays the elapsed time since the start of the running self-optometry. In the left and right eye display column 55, it is displayed whether the procedure being performed at that time is the procedure to be performed for the left eye or the right eye of the subject in the entire progress procedure. The help button 56 is operated by the subject when the subject inputs an instruction to execute the auxiliary operation of the self-optometry. The top button 57 is operated when the screen displayed in the progress procedure display area 51 is returned to the top screen of the self-optometry application.

During the assist of self-eye examination (S24 to S43) described below, as described above, the audio signal input from the microphone 32A to the first information processing apparatus 2A becomes audio by the speaker 33B of the second information processing apparatus 2B. Will be converted. Further, the voice signal input from the microphone 32B to the second information processing device 2B is converted into voice by the speaker 33A of the first information processing device 2A. Therefore, the examiner and the subject can have a conversation while assisting the self-optometry. Further, during the assist of self-optometry, the examiner using the second information processing apparatus 2B can input various instructions for assisting self-optometry by at least one of the operation unit 34B and the microphone 32B. ..

Next, the CPU 21A determines whether or not the manual assistance by the examiner is being executed (S26). In the present embodiment, either indirect assistance or manual assistance is selected as a method for assisting the self-optometry by the examiner. The indirect assist is a method in which the examiner indirectly assists the self-optometry while advancing the self-optometry performed by the self-optometry application according to the progress procedure set in S3. The manual assist is a method of assisting the self-optometry by advancing the optometry according to an instruction input by the examiner instead of the progress of the self-optometry performed according to the progress procedure.

The examiner can make the first information processing apparatus 2A execute either indirect assistance or manual assistance by various methods. As an example, in the present embodiment, the indirect assist is set in advance so that the indirect assist is executed first at the start of the self-optometry assist process. Further, the indirect assistance can be switched to the manual assistance by inputting the operation instruction, the correction value correction instruction, or the procedure omission instruction to the subjective optometry device 1 via various buttons on the operation image area 50. .. However, the method of switching between indirect assistance and manual assistance can be appropriately selected. For example, a button for switching between indirect assistance and manual assistance may be provided on the self-optometry assistance screen.

If the indirect assistance is being executed (S26: NO), the CPU 21A determines whether or not the subject's answer, which has visually recognized the presented optotype, is input by the examiner or the subject (S27). .. In the present embodiment, during the execution of the indirect assistance, the subject operates the operation unit 34B connected to the second information processing apparatus 2B, so that the subject hears the answer from the subject in the second information processing apparatus. You can enter it in 2B. The answer input to the second information processing device 2B is transmitted to the second information processing device 2A. Therefore, even when the subject does not know how to respond to the self-optometry, the progress of the self-optometry is appropriately assisted. Further, in the present embodiment, even during the execution of the indirect assistance, the examiner can input the answer of the result of visually recognizing the optotype by himself / herself, as in the case of S7 (see FIG. 2) described above. .. Therefore, the subject can proceed with the optometry procedure by inputting the answer by himself / herself when he / she receives advice from the examiner and grasps the answer method. However, one of the first information processing device 2A and the second information processing device 2B may accept the answer during the execution of the indirect assistance.

If the subject's answer is not input to either the first information processing device 2A or the second information processing device 2B (S27: NO), the process proceeds to S38 as it is. When the subject's answer is input to the first information processing device 2A or the second information processing device 2B (S27: YES), the input answer and the subject's eye are similarly to S8 (see FIG. 2). Optically specific measured values are stored in the storage device 22A (S28). Next, the CPU 21A determines the next target display operation to be executed by the subjective optometry device 1 according to the progress procedure set in S3 (see FIG. 2) and the progress status at that time, and the determined presentation. A presentation instruction signal (drive signal) for executing the operation is output to the subjective optometry device 1 (S29). That is, the self-optometry performed by the self-optometry application according to the progress procedure is continued thereafter. After that, the process shifts to S38.

Further, if the manual assist is being executed instead of the indirect assist (S26: YES), the CPU 21A determines whether or not the examiner has input an operation instruction for manually advancing at least a part of the progress procedure. Is determined (S31). The examiner gives an operation instruction to the subjective optometry device 1 (that is, optics in the correction optical system 11) based on, for example, the display contents of the self-optometry assist screen (see FIG. 3) or a conversation with the subject. At least one of the instruction of the arrangement operation of the element and the instruction of the display operation of the optotype in the optometric display unit 16) can be determined. In this case, the examiner inputs the determined operation instruction to the second information processing apparatus 2B via the operation unit 34B or the like. The input operation instruction is acquired by the first information processing apparatus 2A via the network 5. When the operation instruction is input and acquired (S31: YES), the CPU 21A transmits a presentation instruction signal (drive signal) for causing the subjective optometry device 1 to execute the instructed operation to the optometry device 1. (S32).

Next, the CPU 21A determines whether or not the correction instruction of the correction value stored in S8 (see FIG. 2) or S28 is input by the self-optometry (S33). When the examiner determines that the correction value (measured value) displayed on the self-optometry assist screen (see FIG. 3) needs to be corrected, the examiner gives an instruction to correct the correction value that needs to be corrected via the operation unit 34B or the like. Is input to the second information processing apparatus 2B. The input correction instruction is acquired by the first information processing apparatus 2A via the network 5. When the correction instruction is input and acquired (S33: YES), the CPU 21A corrects the correction value according to the instruction (S34).

Next, the CPU 21A determines whether or not an omission instruction for at least a part of the progress procedure (at least one of a plurality of tests in the present embodiment) has been input (S35). When the CPU 21A inputs an omission instruction via the second information processing apparatus 2B and the network 5 (S35: YES), the instructed test is omitted from the progress procedure among the plurality of tests included in the progress procedure (S36). ). After that, the process shifts to S38.

Next, the CPU 21A determines whether or not a series of eye examinations for the subject has been completed (S38). For example, the CPU 21A may determine that a series of optometry has been completed when the self-optometry executed according to the progress procedure is completed. Further, the CPU 21A may determine that a series of optometry has been completed when an instruction to end the optometry to the subject is input. When a series of optometry is completed (S38: YES), the process ends.

Next, the CPU 21A determines whether or not the self-optometry continuation restart instruction has been input (S39). The continuous resumption instruction is an instruction to restart the self-optometry from the procedure following the procedure in which the optometry has already been completed among the progress procedures set in S3 (see FIG. 2). For example, the CPU 21A may determine that the continuation restart instruction has been input when the continuation restart button (not shown) is operated by the subject. When the continuation restart instruction is input via the second information processing device 2B and the network 5 (S39: YES), the CPU 21A sets the restart procedure for restarting the self-optometry as a procedure in which the optometry has already been completed. The procedure is set to the next step (S40), and the process returns to the optometry control process (see FIG. 2). In the subsequent processing of S5 to S9, the self-optometry is restarted from the restart procedure set in S40. If the continuation restart instruction is not input (S39: NO), the process proceeds to S42 as it is.

Next, the CPU 21A determines whether or not the instruction to restart the designation of self-optometry has been input (S42). The designated resumption instruction is an instruction to restart the self-optometry from the procedure designated by the examiner among the progress procedures set in S3 (see FIG. 2). In the present embodiment, the examiner gives a designated resumption instruction by designating a resumption procedure for resuming self-optometry on the progress procedure displayed in the progress procedure display field 52 (see FIG. 3) of the self-optometry assist screen. You can enter it. As an example, in the present embodiment, the examiner inputs a designated restart instruction by using a mouse, a touch panel, or the like. In addition, a designated restart instruction button (reset button) for erasing the result of the self-optometry already performed according to the progress procedure and restarting the self-optometry from the beginning of the progress procedure is provided on the self-eye examination assist screen or the like. May be good. When the designated restart instruction is input via the second information processing device 2 and the network 5 (S42: YES), the CPU 21A designates the restart procedure for restarting the self-optometry by the designated restart instruction in the progress procedure. The procedure is set (S43), and the process returns to the optometry control process (see FIG. 2). In the subsequent processing of S5 to S9, the self-optometry is restarted from the restart procedure set in S43.

The technique disclosed in the above embodiment is only an example. Therefore, it is possible to modify the techniques exemplified in the above embodiments. For example, it is possible to perform only some of the techniques exemplified in the above embodiments. As an example, in the subjective optometry system 100 of the above embodiment, when a problem occurs in the self-optometry (S11: YES or S12: YES), the examiner calling process (S21) and the self-optometry by the examiner are performed. Auxiliary processing (S23 to S43) is executed together. However, the optometry system 100 may execute only one of the examiner calling process and the examiner's auxiliary process. For example, even if the examiner is called by the examiner call process, the self-optometry is appropriately assisted.

In the above embodiment, the self-optometry is started with the second information processing device 2B connected to the first information processing device 2A. However, the second information processing device 2B may be connected to the first information processing device 2A after a problem occurs in the progress of self-optometry (S11: YES or S12: YES).

The self-optometry assisting process of the present embodiment (see FIG. 4) is executed in response to an instruction input to the second information processing apparatus 2B located at a remote location. However, the self-optometry assisting process responds to an instruction directly input to the first information processing device 2A (for example, an instruction input to the first information processing device 2A by the examiner operating the operation unit 34A). It may be executed. That is, the examiner at the place where the subjective optometry device 1 is installed may input an instruction for assisting the self-optometry. Further, both the first information processing device 2A and the second information processing device 2B may accept the input of an instruction for assisting the self-optometry. In this case, the examiner can assist the self-optometry at either the place where the subjective optometry device 1 is installed or the remote place. When an instruction for assisting self-optometry is input via the first information processing device 2A, the process of calling the examiner in S21 (see FIG. 4) is executed by the first information processing device 2A. It may be executed in both the first information processing device 2A and the second information processing device 2B.

The self-optometry assisting process shown in FIG. 4 is an example of the “self-optometry assisting step”. The process of outputting the presentation instruction signal in response to the operation instruction in S31 and S32 of FIG. 4 is an example of the “manual progress step”. The process of correcting the correction value in S33 and S34 of FIG. 4 is an example of the “correction value correction step”. The process of omitting the progress procedure in S35 and S36 of FIG. 4 is an example of the “procedure omission step”. In S27 of FIG. 4, the process of acquiring the subject's answer in response to the instruction input by the examiner is an example of the “proxy response acquisition step”. The process of restarting the self-optometry from the next procedure in S39 and S40 of FIG. 4 is an example of the “continuous restart step”. In S42 and S43 of FIG. 4, the process of restarting the self-optometry from the procedure designated by the examiner is an example of the “designated restart step”. The process of restarting the self-optometry in S33 and S34 of FIG. 4 is an example of the “self-optometry restart step”.
