Description

[Technical field]

[0001] The present disclosure relates to an optometry control program executed in a subjective optometry system, and the subjective optometry system. [Background technology]

[0002] There is known a subjective optometry device that measures optical characteristics such as the eye refractive power of a subject's eye by placing an optical element in front of the subject's eye and presenting a test optotype to the subject's eye through the optical element. For example, a subjective optometry device described in Patent Document 1 includes an eye refractive power measurement unit, an optotype presenting unit, and a controller. The eye refractive power measurement unit switches an optical element to be placed in the eye examination window from among a plurality of optical elements included in a correction optical system by a drive unit. The optotype presenting unit switches a test optotype to be presented to the subject's eye. The controller detects a user's operation on an operation panel, and transmits a drive signal to the eye refractive power measurement unit and the optotype presenting unit based on the detected operation.

[0008] According to the optometry control program and subjective optometry system of the present disclosure, subjective optometry can be performed more smoothly. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the accompanying drawings. The items classified in <> below can be used independently or in conjunction with each other. <Summary> The subjective eye examination system exemplified in the present disclosure includes a subjective eye examination device and a first information processing device. The subjective eye examination device has a corrective optical system that changes the optical characteristics of a visual target light beam presented to the subject's eye, and a visual target presenting unit that presents a visual target to the subject's eye, and is used to subjectively measure the optical characteristics of the subject's eye. The first information processing device is an information processing device that is connected to the subjective eye examination device (hereinafter, the first information processing device may also be referred to as a "connection device"). The self-eye examination program is a program that automatically progresses the eye examination based on answers input by the subject.

[0010] The self-eye examination program is executed by the control unit of the first information processing device, whereby a self-eye examination proceeding step, an answer acquisition step, a correction value storage step, and a self-eye examination assisting step are executed by the first information processing device. In the self-eye examination proceeding step, the first information processing device sequentially outputs a plurality of presentation instruction signals to the subjective eye examination device instructing the subject to present an optotype to the subject based on at least the proceeding procedure of the self-eye examination that proceeds automatically (i.e., along the proceeding procedure). In the self-eye examination proceeding step, the first information processing device may control the correction optical system and the optotype presenting unit to perform a plurality of examination items based on the proceeding procedure of the self-eye examination that proceeds automatically. In the answer acquisition step, the first information processing device acquires an answer input by the subject who visually recognizes the presented optotype. In the correction value storage step, the first information processing device stores a correction value of the optical characteristic of the subject's eye acquired based on the answer acquired in the answer acquisition step and the optical characteristics of the optotype and the optotype light beam that were presented by the subjective eye examination device when the answer was acquired. In the self-eye examination assisting step, the first information processing device executes an assisting operation for assisting the progress of the self-eye examination when a problem occurs in the progress of the self-eye examination.

[0011] According to the subjective eye examination system of the present disclosure, the self-eye examination program is executed, so that the subject's eye examination is appropriately performed without the examiner having to proceed with the eye examination. Furthermore, when a problem occurs with the progress of the self-eye examination, an auxiliary operation is executed to assist the progress of the self-eye examination. That is, a function for assisting the progress of the self-eye examination is incorporated into the function of the self-eye examination program. Therefore, for example, while the self-eye examination program is being executed, at least one of the auxiliary operations for the self-eye examination is executed based on advice from the examiner, for example. Therefore, the subjective eye examination is appropriately performed with a reduced burden on the examiner.

[0012] Various devices can be used as the first information processing device that executes the eye examination control program. For example, a personal computer (hereinafter, referred to as "PC") may be used as the first information processing device. Also, a server, a mobile terminal, a smartphone, or the like may be used as the first information processing device.

[0013] The first information processing device may also be configured by combining a plurality of devices. For example, the first information processing device may be configured by a device such as a personal computer and a dedicated controller equipped with 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 configured as the first information processing device.

[0014] In addition, the storage device that stores the eye examination control program can be appropriately selected. For example, the eye examination control program may be stored in a storage device built into the first information processing device, or in a storage device that is detachable from the first information processing device. The eye examination control program may be stored in a storage device built into the dedicated controller described above. In addition, the eye examination control program may be stored in multiple storage devices.

[0015] In the self-eye examination assist step, when the situation of the self-eye examination being performed satisfies a predetermined condition or when an instruction to perform an assist operation is input, an assist operation for assisting the progress of the self-eye examination may be performed. In this case, when a situation occurs in which the subject cannot perform the self-eye examination, the assist operation for the self-eye examination is appropriately performed.

[0016] The conditions of the self-eye examination situation when the auxiliary operation is executed can be appropriately selected. For example, the control unit may determine that the execution conditions of the auxiliary operation are satisfied when a predetermined time has passed without an answer being input from the subject. The control unit may also determine that the execution conditions of the auxiliary operation are satisfied when the answer input by the subject is inappropriate. The method of determining whether or not an answer is inappropriate can be appropriately selected. For example, the control unit may determine that the input answer is inappropriate when the input answer does not satisfy a predetermined answer condition (for example, when an answer different from the candidate answer requested of the subject is input, when the same answer is input consecutively a predetermined number of times or more, or when an answer is input more times than the number of answers requested of the subject, etc.).

[0017] The assisting operation performed in the self-eye examination assisting step may include a calling operation for calling the examiner. In this case, the examiner is called when a problem occurs in the progress of the self-eye examination, so that the subsequent eye examination can be performed appropriately.

[0018] The self-eye examination assistance step may include a manual advancement step of outputting a presentation instruction signal for advancing at least a part of the advancement procedure to the subjective eye examination device in response to an instruction input by the examiner. In this case, the examiner can manually advance the examination or the like in which a problem has occurred among the advancement procedures that were to be advanced by the self-eye examination. Thus, the eye examination of the examinee is more appropriately assisted.

[0019] The self-eye examination assisting step may include a correction value correcting step of correcting at least one of one or more correction values ​​stored by the self-eye examination according to an instruction input by the examiner. In this case, for example, even if there is a correction value for which the measurement by the self-eye examination has failed, the correction value is corrected at the examiner's discretion. Therefore, the eye examination of the examinee proceeds smoothly.

[0020] The self-eye examination assistance step may include a test omission step of omitting at least a part of the procedure in response to an instruction input by the examiner. In this case, the examiner can omit a step that is determined to be unnecessary among the predetermined procedures. Thus, the eye examination of the examinee can be smoothly performed.

[0021] The method of inputting instructions by the examiner to omit at least a part of the procedure can be selected appropriately. For example, the examiner may input an instruction to select a test to be omitted from among a plurality of tests executed according to the procedure into the first information processing device. In this case, the control unit of the first information processing device may omit the selected test from the procedure. The examiner may also input a timing to resume the temporarily stopped self-eye examination to the first information processing device as a timing later than the procedure to be omitted. In this case, the control unit of the first information processing device may omit some of the procedures by resuming the self-eye examination from the input timing.

[0022] The self-eye examination assisting step may include a proxy answer acquiring step. In the proxy answer acquiring step, when the optotypes are presented to the subject according to the procedure in the self-eye examination proceeding step, the control unit acquires the answer of the subject who visually recognizes the presented optotype in response to an instruction input by the examiner. In this case, the examiner can hear the answer from the subject who visually recognizes the optotype during the process in which the optotypes are presented to the subject in sequence according to the procedure of the self-eye examination, and input the answer he / she has heard by himself / herself. Therefore, even if the subject does not understand the answering method in the self-eye examination, the examiner can appropriately assist the self-eye examination by inputting the answer he / she has heard from the subject.

[0023] The self-eye examination assistance step may include a continuation resumption step for resuming the temporarily stopped self-eye examination from the next step of the procedure in which the eye examination has already been completed (e.g., a completed test, etc.). In this case, the self-eye examination is resumed from the next step of the procedure in which the eye examination has already been completed. Therefore, even after the assistance for the self-eye examination is completed, the self-eye examination continues appropriately according to the procedure.

[0024] The self-eye examination assistance step may include a designated resumption step for resuming the temporarily stopped self-eye examination from a procedure (e.g., a designated test, etc.) designated by the examiner among the proceeding procedures. In this case, the examiner can resume the self-eye examination from the procedure designated by the examiner when a problem that occurred during the self-eye examination is resolved, etc. Thus, an excessive increase in the burden on the examiner to assist in the eye examination is suppressed.

[0025] The procedure for the self-eye examination may determine a plurality of tests (examinations) to be performed on the subject and the order in which the plurality of tests are performed. In the self-eye examination proceeding step, the plurality of tests may be performed in order according to the procedure. In this case, the plurality of tests on the subject's eye proceeds appropriately and automatically. Furthermore, the examiner can provide appropriate assistance for a test that is determined to require assistance among the plurality of tests (for example, a test in which a satisfactory correction value was not obtained in the self-eye examination, etc.).

[0026] The self-eye examination assist step may include a procedure display step of displaying the procedure on a display device. The display device may be disposed at a base where the examiner waits, and may be disposed at a base different from the base where the subjective eye examination device is disposed, or may be disposed at the same base where the subjective eye examination device is disposed. In the designation resumption step, an input of a designation instruction for a procedure for resuming the self-eye examination (hereinafter referred to as a "resuming procedure") may be accepted on the procedure displayed by the display device. In this case, the examiner can designate the resuming procedure for resuming the self-eye examination while appropriately grasping the details of the procedure and the progress status, etc., from the displayed procedure.

[0027] A specific method for accepting input of a restart procedure on the displayed procedure may 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 a procedure (e.g., a specific test, etc.) corresponding to a position where the touch panel is operated among the displayed procedure as the restart procedure specified by the examiner. Also, a mouse or the like may be provided for moving a pointer within the display area of ​​the display device. In this case, the control unit may process a procedure corresponding to the position of the pointer among the displayed procedure as the restart procedure specified by the examiner.

[0028] The control unit may also display, on the procedure, at least one of the procedure being performed at the time and the procedure being performed when a problem occurred among the entire procedure (e.g., a plurality of tests included in the procedure). In this case, the examiner can properly grasp the progress of the self-eye examination from the displayed procedure.

[0029] As described above, resuming a self-eye examination that has been temporarily stopped provides various benefits. For example, in a cross cylinder test, which is one of the tests performed by a subjective eye examination system, two point clouds are presented to the subject. However, if the relative position between the test window of the correction optical system and the subject's eye is shifted, the subject may only be able to see one of the two point clouds. In this case, the subject cannot perform the self-eye examination. However, according to the subjective eye examination system of the present disclosure, while the self-eye examination is temporarily stopped, the examiner can give advice to adjust the position of the subject's eye relative to the test window, assist the progress of the cross cylinder test, and then resume the self-eye examination performed by the subject alone. In this way, when a self-eye examination that has been temporarily stopped is resumed, a useful effect is obtained for both the examiner and the subject.

[0030] 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 an examiner is in a remote location different from the location of the examinee, the examiner can appropriately assist the examinee in the self-eye examination from a remote location by inputting an instruction to the second information processing device.

[0031] If a problem occurs in the progress of the self-eye examination (for example, if an instruction to execute an auxiliary operation is input, etc.), the control unit of the first information processing device may output an instruction to execute a calling operation to call the examiner to the second information processing device. In this case, even if the examiner is in a remote location different from the subject's location, the examiner can easily understand that a problem has occurred in the progress of the self-eye examination.

[0032] However, the self-eye examination assistance step may be executed according to an instruction directly input to the first information processing device (for example, an instruction input to an operation unit of the first information processing device). That is, an examiner at a place where the subjective eye examination device and the first information processing device are installed may input an instruction to execute the self-eye examination assistance step. In this case, for example, the operation unit (examiner controller) of the first information processing device used for inputting instructions from the examiner may be a dedicated controller provided in the subjective eye examination device, or may be a general-purpose user interface such as a mouse or a tablet.

[0033] Furthermore, when a second information processing device is used, the number of the second information processing device may be one or more than one. Similarly to the first information processing device, various devices (e.g., PC, mobile terminal, smartphone, etc.) can be used for the second information processing device. The second information processing device may already be connected to the first information processing device when the self-eye examination is performed, or may be connected to the first information processing device after a problem occurs in the self-eye examination.

[0034] In addition, when the second information processing device is used, the control unit of each of the first information processing device and the second information processing device may execute a remote conversation step of assisting the conversation between the examiner and the subject by transmitting and receiving at least voice data (which may be both voice data and image data) to each other. In this case, the examiner at a remote location can appropriately assist the self-eye examination by understanding the condition of the subject through the conversation.

[0035] <Setting the inspection timing when starting auxiliary operation> The self-eye examination assisting step may include a receiving step of receiving, from the subject, an input of a call execution instruction, which is an instruction for executing a call operation to call an assistant (e.g., an examiner), and a call execution step of executing the call operation based on the call execution instruction received in the receiving step. Furthermore, the self-eye examination assisting step may include an examination timing setting step of setting an examination timing for starting the assisting operation based on the call execution instruction received in the receiving step so that the assisting operation can be started for the examination item at the time when the call execution instruction is input. The examination timing for starting the assisting operation is used as the examination start time point at which the assisting operation is started in the eye examination progress procedure (examination flow). In this case, for example, the examiner can smoothly perform the assisting operation for the examination item in which the subject has difficulty, and can effectively assist the subject in the self-examination.

[0036] As a method of setting the examination timing for the examination item at the time when the call execution instruction is input, for example, the progress of the self-eye examination is temporarily stopped at the time when the call execution instruction is input, so that the examination timing can be set for the examination item at the time when the call execution instruction is input. In this way, for example, the progress of the self-eye examination is temporarily stopped at the time when the call execution instruction is input, so that the possibility of the examination proceeding and the acquisition of erroneous examination results can be avoided in advance. In addition, the burden on the subject can be reduced.

[0037] In addition, the method of setting the examination timing for the examination item at the time when the call execution instruction is input is not limited to the above. For example, the examination item at the time when the call execution instruction is input may be stored in a storage unit, and the examination timing may be set for the examination item at the time when the call execution instruction is input based on the examination item stored in the storage unit. This makes it possible to start the examination from the examination item at the time when the call execution instruction is input, and, if the examination is to be performed appropriately, to proceed with the examination until assistance by the examiner is started.

[0038] In addition, a display that allows the user to distinguish the test item for which the call execution instruction has been input may be displayed on the display device, so that the test item at the time when the call execution instruction is input may be selected with priority. Also, the test items stored in the memory unit may be displayed on the display device, so that assistance with the test can be easily provided.

[0039] <Restrictions on answer input> In the answer acquisition step, when a call execution instruction is input, the input of answers input after the time point when the call execution instruction is input may be restricted. In this way, for example, by restricting answers from the subject, it is possible to prevent the examination from proceeding erroneously due to an erroneous operation by the subject when the examiner provides assistance. Furthermore, when the self-eye examination is resumed, the restriction on the input of answers may be lifted. In this way, for example, the self-eye examination can be resumed smoothly.

[0040] The above-mentioned restriction on answer input is not limited to the case where a call execution instruction is input, and when an instruction to execute an auxiliary operation is input in the answer acquisition step, the input of an answer input after the execution instruction is input can be restricted to prevent the examination from proceeding erroneously due to, for example, an erroneous operation by the subject. In other words, the input of the instruction to execute the auxiliary operation may be, in addition to the call execution instruction, for example, a pause instruction to stop the progress of the self-eye examination and execute the auxiliary operation. In this case, the instruction to execute the auxiliary operation may be input by, for example, the subject or the examiner.

[0041] <Limitation of examiner controller input> In the self-eye examination assisting step, until the call execution instruction is input, at least a part of the operation input from the examiner's controller for the examiner, who is the assistant, to operate the subjective eye examination device may be restricted. In this way, for example, when the self-examination is in progress, the operation input from the examiner's controller is restricted, thereby preventing an inexperienced examiner from touching the controller and interfering with the examination during the self-examination.

[0042] In this case, when a call execution instruction is input, the restriction on the operation input from the examiner's controller may be lifted. This allows the examiner to smoothly provide assistance when a call execution instruction is input. Furthermore, when the self-eye examination is resumed, at least a part of the operation input from the examiner's controller may be restricted. This allows, for example, examination to be preferably performed after the self-eye examination is resumed.

[0043] The partial restriction of the operation input is not limited to the case where a call execution instruction is input, and in the self-eye examination assistance step, by restricting at least a part of the operation input from the examiner's controller for the examiner, who is the assistant, to operate the subjective eye examination device until an instruction to execute the auxiliary operation is input, it is possible to prevent an inexperienced examiner from touching the controller and interfering with the examination in the self-examination. Furthermore, when an execution instruction is input, the restriction of the operation input from the examiner's controller may be lifted. That is, the input of the instruction to execute the auxiliary operation may be, in addition to the call execution instruction, for example, a pause instruction to stop the progress of the self-eye examination and execute the auxiliary operation. In this case, the instruction to execute the auxiliary operation may be input, for example, by the examinee or the examiner.

[0044] In the self-eye examination assistance step, when an instruction to execute an assistance operation is input, the answer from the subject may be restricted and the restriction on the operation input of the examiner's controller may be lifted. This allows, for example, the subject to reliably switch between the self-eye examination by the subject himself / herself and assistance by the examiner, and prevents each examination from progressing unexpectedly.

[0045] The self-eye examination assist step may include an output step of outputting the elapsed time from the time when the call execution instruction was input, whereby, for example, the elapsed time from the time when the call execution instruction was input can be confirmed.

[0046] When the assist operation is started for the examination item at the time when the call execution instruction is input, the self-eye examination assist step may control the subjective device body so that the examination state is the state at the time when the call execution instruction is input. For example, the optotype at the time when the call execution instruction is input may be presented to the optotype presenting unit, or the correction value at the time when the call execution instruction is input may be set in the correction optical system. As a result, for example, the examination state at the time of the call execution is maintained, and the examinee can smoothly perform the assist operation from the examination state in which the examinee is in difficulty, thereby reducing the examination with unnecessary settings.

[0047] In this case, for example, the subjective device body may be automatically controlled to bring the test state to the state when the recall command is input, or the test state when the recall command is input may be displayed on the display device and adjusted to the test state when the recall command is input by the examiner's manual operation. By performing both the presentation of the optotype and the setting of the correction value, the test state at the time of the recall can be more accurately reproduced, but either the presentation of the optotype or the setting of the correction value may be performed.

[0048] When the assist operation is started in the examination item at the time when the call execution instruction is input, the self-eye examination assist step may control the subjective device body so that the initial state of the examination item at the time when the call execution instruction is input is reached. For example, the optotype at the start of the examination in the examination item at the time when the call execution instruction is input may be presented in the optotype presenting section, or the correction value at the start of the examination in the examination item at the time when the call execution instruction is input may be set in the correction optical system. This allows the examination to be performed from the initial state of the examination at the time of the call execution, for example, so that in the case where the examination at the time when the call execution instruction is input is inappropriate, the examination can be reset once, and the examination can be performed from the start of the examination, which results in the examination being performed smoothly. By presenting the optotype and setting the correction value, the initial state of the examination in the examination at the time of the call execution can be more accurately reproduced, but one of presenting the optotype and setting the correction value may be performed. In this case, for example, the subjective device body may be automatically controlled to return to the initial state of the test item at the time the call execution instruction is input, or the initial state of the test item at the time the call execution instruction is input may be displayed on the display device and adjusted to the initial state of the test item at the time the call execution instruction is input by manual operation by the examiner.

[0049] The correction value (initial value) set as the initial state may be set based on at least one of the objective measurement data, the previous glasses data, and the past subjective measurement data. Of course, for example, an initial value different from the above data may be used as the initial value. In this case, for example, an arbitrary value (for example, a default value (for example, 0, etc.)) may be set as the initial value.

[0050] For example, the objective measurement data may be data obtained by objectively measuring the optical characteristics of the subject's eye. In this case, for example, the optical characteristics of the subject's eye that are objectively measured include ocular refractive power (e.g., spherical power, cylindrical power, cylindrical axis angle, etc.), polarization characteristics, interpupillary distance, etc. In addition, for example, the previous glasses data may be data obtained by measuring the optical characteristics of glasses worn by the subject. In this case, for example, the optical characteristics of the glasses include refractive power (e.g., spherical power, cylindrical power, cylindrical axis angle, etc.), polarization characteristics, interpupillary distance, etc. In addition, for example, the past subjective measurement data may be subjective measurement data that is a past subjective measurement result of a subject performing a subjective measurement. For example, the subjective measurement data may be data obtained by subjectively measuring the optical characteristics of the subject's eye. In this case, for example, the optical characteristics of the subject's eye that are subjectively measured include the eye refractive power (for example, spherical power, cylindrical power, cylindrical axis angle, etc.), polarization characteristics, interpupillary distance, and the like.

[0051] A first control for controlling the subjective device body so as to be in an examination state at the time when the call execution instruction is input, and a second control for controlling the subjective device body so as to be in an initial state for the examination item at the time when the call execution instruction is input may be selectively executed. In this case, the examiner controller may be configured to select the first control and the second control. This allows the examiner to, for example, select the device setting for assisting the examiner according to the examination situation at the time when the call execution instruction is input after hearing about the examination situation.

[0052] When the examiner uses the first control and the second control, for example, if the test is in the beginning of the test in the test item at the time when the call execution instruction is input, the second control may be selected, and if the test is in the end of the test in the test item at the time when the call execution instruction is input, the first control may be selected. In this case, if the test is a one-eye test, the device setting may be performed only for the eye to be measured. In addition, the use is not limited to the above-mentioned use, and the examiner may appropriately select the control desired.

[0053] The self-eye examination assist step may be executed according 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. For example, when an examiner is in a remote location different from the subject's location, it is difficult to grasp the progress of the self-eye examination and difficult to grasp the examination item at the time when the call execution instruction is input. Therefore, in the self-eye examination assist step, by setting the examination timing for starting the assist operation so that the assist operation can be started for the examination item at the time when the call execution instruction is input, even if the examiner is in a remote location, the examiner can smoothly perform the assist operation for the examination item in which the subject has difficulty, and therefore the examiner can be effectively assisted in the self-examination. <Embodiment> (System Configuration) Hereinafter, one of the typical embodiments of the present disclosure will be described with reference to the drawings. As shown in FIG. 1, a subjective optometry system 100 of this embodiment includes a subjective optometry device 1 and a first information processing device 2A. The subjective optometry device 1 is used to subjectively measure the optical characteristics of the subject's eye. The optical characteristics of the subject's eye measured by the subjective optometry device 1 of this embodiment are the eye refractive power. The measured eye refractive power may be at least one of the spherical power, cylindrical power, and astigmatism axis angle of the subject's eye. The first information processing device 2A is connected to the subjective optometry device 1. Hereinafter, the first information processing device 2A may be referred to as a connection device. The first information processing device 2A is connected to a second information processing device 2B, which is another information processing device, via a network 5. That is, the first information processing device 2A of this embodiment may be remotely accessed by the second information processing device 2B. Hereinafter, each device will be described in detail.

[0054] The subjective optometry apparatus 1 includes an eye refractive power measuring unit 10, an optotype presenting unit 15, and a relay unit 19.

[0055] The eye refractive power measuring unit 10 includes a correction optical system 11 and a drive unit 12. The correction optical system 11 changes the optical characteristics of the visual target light beam presented to the subject's eye. That is, the correction optical system 11 changes at least one of the spherical power, cylindrical power, astigmatism axis angle, polarization characteristics, and aberration amount of the visual target light beam. As an example, the correction optical system 11 of this embodiment changes the optical characteristics of the visual target light beam by switching the optical element arranged in the test window in front of the subject's eye among the multiple optical elements. In the correction optical system 11 of this embodiment, a lens disk for the left eye and a lens disk for the right eye are used, in which multiple optical elements are arranged on the same circumference. Each of the lens disk for the left eye and the lens disk for the right eye may be one or more. For example, at least one of a spherical lens, a cylindrical lens, a cross cylinder lens, a rotary prism, and a wavefront modulation element may be used as the optical element. The driving unit 12 changes the optical characteristics of the visual target light beam by driving the correction optical system 11. In this embodiment, the driving unit 12 drives the correction optical system 11 by rotating each of the lens disks for the left eye and the lens disks for the right eye to switch the optical element arranged in the test window. For example, a step motor or the like can be used as the driving unit 12. The driving unit 12 is driven in response to a driving signal.

[0056] The optotype presenting unit 15 presents a test optotype (for example, at least one of a Landolt ring optotype and a letter) to the eye to be examined, and switches the test optotype to be presented to the eye to be examined. In detail, the optotype presenting unit 15 includes an optotype presenting section 16 and a driving section 17. The optotype presenting section 16 presents a test optotype to the eye to be examined. For example, the optotype presenting section 16 may be at least one of a space-saving optotype projection device that projects the test optotype to the eye to be examined via a concave mirror, a chart projector that projects the test optotype on a screen, and a display that displays the test optotype. The optotype presenting section 16 is disposed at approximately the same height as the eye refractive power measuring unit 10 so that the distance from the eye to be examined is a predetermined optical distance. The driving section 17 drives the optotype presenting section 16 to switch the test optotype to be presented to the eye to be examined. The driving section 17 is driven in response to a driving signal.

[0057] The relay unit 19 relays a drive signal between the first information processing device 2A and the drive units 12 and 17. In this embodiment, the system of the drive signal output from the first information processing device 2A is different from the system of the drive signal capable of controlling at least one of the drive units 12 and 17. The relay unit 19 of this embodiment converts the drive signal received from the first information processing device 2A into a drive signal capable of controlling the drive units 12 and 17, and transmits it to the drive units 12 and 17. Furthermore, as an example, when the relay unit 19 of this embodiment receives one drive signal for driving both the two drive units 12 and 17 from the first information processing device 2A, it converts the received one drive signal into two drive signals for driving each of the two drive units 12 and 17, and transmits them to each of the two drive units 12 and 17.

[0058] The first information processing device 2A and the second information processing device 2B will be described. At least one of various information processing devices capable of processing various information can be adopted as the first information processing device 2A and the second information processing device 2B. As an example, a personal computer (hereinafter referred to as "PC") is used as the first information processing device 2A and the second information processing device 2B of the present embodiment. However, the information processing device that can function as the first information processing device 2A and the second information processing device 2B of the present embodiment is not limited to a PC. For example, a server, a mobile terminal, a smartphone, or the like may be used as at least one of the first information processing device 2A and the second information processing device 2B. At least one of the first information processing device 2A and the second information processing device 2B may be configured by a plurality of devices. For example, the first information processing device 2A may be configured by a dedicated controller having a controller and a storage device, and a personal computer.

[0059] The first information processing device 2A and the second information processing device 2B are connected in a communicable state via a network (e.g., the Internet) 5. In the example shown in FIG. 1, a case is illustrated in which a plurality of second information processing devices 2B are connected to one first information processing device 2A. However, one second information processing device 2B may be connected to one first information processing device 2A. Also, one second information processing device 2B may be connected to a plurality of first information processing devices 2A.

[0060] The first information processing device 2A is disposed at a site (e.g., an eyeglass store or a hospital) where subjective eye examination is performed on a subject. The first information processing device 2A includes a CPU 21A and a storage device 22A. The CPU 21A is a control unit (controller) that controls the first information processing device 2A. The storage device 22A can store programs and various data. In this embodiment, an eye examination control program is stored in the storage device 22A.

[0061] The first information processing device 2A is connected to the subjective optometry device 1 (specifically, the relay unit 19 of the subjective optometry device 1) in a communicable state. The connection standard between the first information processing device 2A and the subjective optometry device 1 may be various standards such as LAN. The first information processing device 2A is also connected to the objective optometry device 3 in a communicable state. The objective optometry device 3 objectively measures the optical characteristics of the subject's eye (for example, at least one of spherical power, cylindrical power, and astigmatism axis angle). The connection standard between the first information processing device 2A and the objective optometry device 3 may be various standards such as LAN. The objective optometry device 3 may be connected to the relay unit 19. The measurement results by the objective optometry device 3 may be stored in a storage device provided in the relay unit 19.

[0062] The first information processing device 2A is connected to a camera 31A, a microphone 32A, a speaker 33A, an operation unit 34A, and a display unit 35A. The camera 31A captures an image. In particular, the camera 31A in this embodiment is used to capture a moving image of the subject. The microphone 32A converts sound into an audio signal and outputs it. The speaker 33A converts the audio signal into sound. The operation unit 34A is operated by a user (e.g., a subject, etc.) to input various instructions. For the operation unit 34A, at least one of a keyboard, a mouse, a touch panel, etc. may be used. In addition, a dedicated operation unit (e.g., a joystick, etc.) suitable for inputting answers to subjective eye examinations may be used as the operation unit 34A. The display unit 35A displays various images. For the display unit 35B, various devices capable of displaying images (e.g., at least one of a monitor, a display, and a projector, etc.) may be used.

[0063] The second information processing device 2B is disposed at the base of an examiner (for example, an eyeglass store clerk, a doctor, or a nurse who is familiar with eye examinations using the subjective eye examination device 1) who can perform eye examinations using the subjective eye examination device 1. The second information processing device 2B includes a CPU 21B and a storage device 22B. The CPU 21B is a control unit (controller) that controls the second information processing device 2B. The storage device 22A can store programs, various data, and the like.

[0064] The second information processing device 2B is connected to a camera 31A, a microphone 32A, a speaker 33A, an operation unit 34A, and a display unit 35A. As for these devices, various devices can be used, similar to the devices connected to the first information processing device 2A described above. (Program / eye examination method) The programs installed in the first information processing device 2A of this embodiment will be described. As described above, the storage device 22A of the first information processing device 2A stores an eye examination control program for executing the eye examination control process (see FIG. 2). The eye examination control program includes a drive control program for executing drive control and a self-eye examination program for executing the self-eye examination. The drive control program transmits a control signal for controlling the drive of the subjective eye examination device 1 to the subjective eye examination device 1. The self-eye examination program automatically proceeds with the eye examination using the subjective eye examination device 1 based on the answer input by the subject. The drive control program for executing the drive control program and the self-eye examination program for executing the self-eye examination may be constructed and prepared separately, or may be incorporated into one program.

[0065] A subjective eye examination method that can be performed by the subjective eye examination system 100 of this embodiment will be described. The subjective eye examination system 100 of this embodiment can perform self-eye examination and remote eye examination. The self-eye examination is an eye examination performed by a self-eye examination program. That is, in the self-eye examination, the eye examination basically proceeds automatically based on the answers input by the examinee. In addition, in the subjective eye examination system 100 of this embodiment, when a problem occurs in the progress of the self-eye examination, a self-eye examination assistance process is performed to assist the progress of the self-eye examination. The self-eye examination assistance process can also be performed in response to an instruction signal input to the second information processing device 2B at a remote location. Therefore, even if a problem occurs in the progress of the self-eye examination, the eye examination can be easily performed smoothly. The following will focus on the explanation of the self-eye examination. (Ophthalmology control processing) An example of an eye examination control process executed by the first information processing device 2A of the subjective eye examination system 100 of this embodiment will be described with reference to Fig. 2 to Fig. 4. In the eye examination control process, for example, a process for controlling the self-eye examination, a process for assisting the self-eye examination, etc. are executed. When an instruction to start a subjective eye examination of the subject's eye is input to the first information processing device 2A, the CPU 21A of the first information processing device 2A executes the eye examination control process exemplified in Fig. 2 according to the eye examination control program.

[0066] As an example, the eye examination control process of this embodiment is executed in a state where communication (e.g., remote access, etc.) of one or more second information processing devices 2B with the first information processing device 2A is established. However, communication between the first information processing device 2A and the second information processing device 2B may be established during execution of the eye examination control process (e.g., at the start of the self-eye examination auxiliary process shown in FIG. 4). In addition, the communication method between the first information processing device 2A and the second information processing device 2B may also be appropriately selected. For example, the remote access of the second information processing device 2B to the first information processing device 2A may be established by using RAS (remote access service).

[0067] First, the CPU 21A acquires objective eye examination results (S1). As an example, the first information processing device 2A of the present embodiment acquires objective eye examination results for the same subject from an objective eye examination device 3 (see FIG. 1) connected via a LAN or a relay unit 19 or the like. However, the CPU 21A may acquire objective eye examination results for the same subject, for example, via a removable memory or a network 5 or the like. In addition, the objective eye examination results may be input by a user via an operation unit 34A or the like. If there are no objective eye examination results for the same subject, the process of S1 may be omitted.

[0068] Next, the CPU 21A sets the procedure for the self-eye examination (S3). In the procedure display field 52 in FIG. 3, a part of an example of the procedure for the self-eye examination used in the subjective eye examination system 100 of this embodiment (only the procedure for the right eye in FIG. 3) is displayed. As illustrated in FIG. 3, the procedure used in this embodiment determines a plurality of tests (a plurality of examinations) to be performed on the examinee and the order of performing the plurality of tests. As an example, in the 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 examinee's right eye, and then 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 examinee's left eye. In the R / G test (S), the spherical power of the examinee's eye is measured. In the cross cylinder test (A), the astigmatism axis angle of the examinee's eye is measured. The cross cylinder test (C) measures the astigmatism of the eye. The R / G test then checks whether the eye has accommodated during the previous test. The VA test measures the maximum visual acuity of the eye.

[0069] In the case where the result of the objective eye examination for the same subject is obtained in S1, the procedure for the self-eye examination is set in S3 according to the result of the objective eye examination (for example, the ocular refractive power (at least one of spherical power, astigmatism power, and astigmatism axis angle) measured for the same eye to be examined). For example, in each test included in the procedure, the optical element to be initially placed in the test window of the correction optical system 11 and the type and size of the optotype to be presented by the optotype presenting unit 16 may be set according to the result of the objective eye examination. In addition, if the astigmatism power obtained by the objective eye examination is equal to or less than a threshold value, a procedure that omits tests related to astigmatism (for example, the cross cylinder test (A) and the cross cylinder test (C)) may be set. In addition, in the case where the result of the objective eye examination is not obtained in S1, a default procedure may be set in S3.

[0070] Next, the CPU 21A determines the next optotype presenting operation to be performed by the subjective optometry device 1 according to the procedure set in S3 and the progress of the self-eye examination, and outputs a presenting instruction signal (drive signal) to the subjective optometry device 1 to perform the determined presenting operation (S5). In detail, in S5 of this embodiment, at least one of the optical element to be placed in the test window of the correction optical system 11 and the optotype to be presented by the optotype presenting unit 16 is determined as the next presenting operation. A drive signal for at least one of the drive unit 12 and the drive unit 17 to perform the determined operation is transmitted to the subjective optometry device 1. When transmitting the drive signal to the subjective optometry device 1, the CPU 21A outputs a guide voice according to the test contents from the speaker 33A. Therefore, the subject can see the presented test optotype after properly understanding the test contents.

[0071] In this embodiment, the driving signal is transmitted from the first information processing device 2A to the driving units 12 and 17 via the relay unit 19 (see FIG. 1) described above. Therefore, the signal transmitted from the first information processing device 2A does not need to go through a dedicated controller or the like. Therefore, signal processing by a dedicated controller or the like is omitted, and eye examination is performed more smoothly.

[0072] In the self-eye examination, the subject understands the contents of the examination through the guidance voice, visually recognizes the test target presented by the subjective eye examination device 1, and inputs an answer based on the visual recognition result into the first information processing device 2A. As an example, in the present embodiment, the subject operates a dedicated operation unit (subject controller) 34A suitable for inputting answers to subjective eye examinations to input answers. However, answers may also be input through a general operation unit 34A (for example, a mouse, a touch panel, or a keyboard). Also, answers may be input through a voice signal converted by the microphone 32A.

[0073] The CPU 21A judges whether or not an answer has been input from the subject (S7). When an answer has been input (S7: YES), the input answer and the correction value (measurement value) of the optical characteristic of the subject's eye are stored in the storage device 22A (S8). The correction value of the optical characteristic of the subject's eye is acquired based on the answer input in S7, the target presented to the subject's eye when the answer was input, and the optical characteristic of the optical element arranged in the test window of the correction optical system 11 (i.e., the optical characteristic of the target light beam).

[0074] Next, if the series of self-eye examinations is not yet completed (S9: NO), the process returns to S5, and the self-eye examination continues according to the progress procedure. As an example, in the VA test of this embodiment, if the answer from the subject acquired in S7 is correct, the CPU 21A determines the next optotype presenting operation so that the optotype to be presented by the optotype presenting unit 16 is an optotype with a visual acuity value one step higher than that of the optotype previously presented (for example, an optotype with a size one step smaller). If the answer from the subject acquired in S7 is incorrect, the CPU 21A determines the next optotype presenting operation so that the optotype to be presented by the optotype presenting unit 16 is an optotype with a visual acuity value one step lower than that of the optotype previously presented (for example, an optotype with a size one step larger). In addition, the CPU 21A may determine the correction power of the optical element to be placed in the test window of the correction optical system 11 as the next optotype presenting operation together with switching of the optotype.

[0075] It should be noted that, when the processes of S7 to S9 are repeatedly executed and the series of self-eye examinations are successfully completed (S9: YES), the eye examination control process ends directly.

[0076] If no answer is input from the subject (S7: NO), it is determined whether the self-eye examination situation satisfies a predetermined condition that is likely to be inappropriate (S11). As an example, in this embodiment, if a predetermined time has passed without an answer being input from the subject after the presentation instruction signal is transmitted in S5, it is determined that the predetermined condition is satisfied. Also, if the answer input by the subject is inappropriate (for example, if an answer different from the candidate answer requested by the subject is input, if the same answer is input consecutively a predetermined number of times or more, or if an answer is input more times than the number of answers requested from the subject, etc.), it is determined that the predetermined condition is satisfied. If it is determined that the predetermined condition is satisfied (S11: YES), a self-eye examination assistance process is executed (S13).

[0077] Also, if the subject has not input a response (S7: NO) and the self-eye examination conditions are not met (S11: NO), the CPU 21A judges whether or not the subject has input an instruction to execute the auxiliary operation of the self-eye examination (S12). As an example, in this embodiment, the subject can input an instruction to execute the auxiliary operation of the self-eye examination by operating the help button 70 provided on the dedicated operation unit (subject controller) 34A or a help button displayed on the display unit 35A. If no instruction has been input (S12: NO), the process returns to S7. If an instruction to execute the auxiliary operation is input (S12: YES), the self-eye examination auxiliary process is executed (S13).

[0078] The details of the self-eye examination assistance process will be described with reference to FIG. 4. First, the CPU 21A executes an examiner call process (S21). As an example, in S21 of this embodiment, the CPU 21A transmits an examiner call instruction via the network 5 to one or more second information processing devices 2B that have established remote access to the first information processing device 2A (S4). The examiner call instruction is an instruction to cause the second information processing device 2B to execute an examiner call operation to request assistance in the self-eye examination from the examiner. The call operation may be performed by at least one of a method such as outputting a sound and displaying an image. By performing the call operation, the user (examiner) of the second information processing device 2B can appropriately grasp that assistance in the self-eye examination (remote assistance in this embodiment) is required.

[0079] Next, the CPU 21A judges whether or not there is a response from the examiner who is the user of the second information processing device 2B (S22). If there is no response from the examiner from any of the second information processing devices 2B (S22: NO), it is impossible to assist the examiner in the self-eye examination, so the judgment of S22 is repeated and a standby state is entered. If the user of any of the second information processing devices 2B is in a state where he or she can assist in the self-eye examination and inputs a response instruction to the second information processing device 2B (S22: YES), the process proceeds to S23.

[0080] Next, the CPU 21A starts a call process by starting transmission and reception of voice data with the second information processing device 2B used by the examiner assisting the self-eye examination (S23). As a result, the assist process for the self-eye examination described below is executed in a state in which the examinee and the examiner can talk to each other. In detail, the CPU 21A transmits voice data inputted by the microphone 32A to the second information processing device 2B. The CPU 21A also receives voice data inputted to the second information processing device 2B via the microphone 32B and outputs it to the speaker 33A. The CPU 21A may transmit and receive image data with the second information processing device 2B together with the voice data. In this case, the CPU 21A may transmit image data inputted by the camera 31A to the second information processing device 2B. The CPU 21A may also receive image data inputted to the second information processing device 2B via the camera 32B and display it on the display unit 35A.

[0081] Next, the CPU 21A displays a self-eye examination assistance screen (see FIG. 3) on the display unit 35B of the second information processing device 2B used by the examiner who assists the self-eye examination (S24). As shown in FIG. 3, the self-eye examination assistance screen in this embodiment includes an operation image area 50 and a progress procedure display area 51.

[0082] In the operation image area 50, an operation image including information on the optical characteristics of the target light beam to be presented to the subject's eye is displayed. In the operation image of this embodiment, values ​​related to the optical characteristics of the target light beam to be presented to the subject's eye are displayed for each type of optical characteristics. The examiner can specify the value for a desired type of optical characteristics (spherical power, cylindrical power, astigmatism axis angle, etc.) by operating various buttons and values ​​on the operation image area 50 via an operation unit such as a touch panel or a mouse. When the eye examination is performed appropriately, the correction value of the optical characteristics displayed in the operation image becomes the measured value of the optical characteristics of the subject's eye.

[0083] In this embodiment, the procedure display area 51 is displayed on the display unit 35A connected to the first information processing device 2A in addition to the display unit 35B connected to the second information processing device 2B. The procedure display area 51 in this embodiment is provided with a 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 procedure display field 52 displays the procedure set for the self-eye examination being performed. In the example shown in FIG. 3, the procedure being performed at that time among the entire procedure (i.e., multiple tests included in the procedure) is displayed on the procedure by an arrow 53 and a thick frame.

[0084] The elapsed time display field 54 displays the time that has elapsed since the self-eye examination in progress was started. The left / right eye display field 55 displays whether the procedure being performed at that point in the entire procedure is being performed for the left eye or the right eye of the subject. The help button 56 is operated by the subject when the subject inputs an instruction to perform an auxiliary operation of the self-eye examination. The top button 57 is operated to return the screen displayed in the procedure display area 51 to the top screen of the self-eye examination program.

[0085] During assistance with the self-eye examination (S24 to S43) described below, as described above, the voice signal input from the microphone 32A to the first information processing device 2A is converted into voice by the speaker 33B of the second information processing device 2B. Also, 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 during assistance with the self-eye examination. Also, during assistance with the self-eye examination, the examiner using the second information processing device 2B can input various instructions for assistance with the self-eye examination by at least one of the operation unit 34B and the microphone 32B.

[0086] Next, the CPU 21A judges whether or not manual assistance is being performed by the examiner (S26). In this embodiment, either indirect assistance or manual assistance is selected as a method for the examiner to assist the self-eye examination. Indirect assistance is a method in which the examiner indirectly assists the self-eye examination performed by the self-eye examination program while progressing the self-eye examination according to the progression procedure set in S3. Manual assistance is a method in which the examiner assists the self-eye examination by progressing the eye examination according to instructions input by the examiner, instead of progressing the self-eye examination according to the progression procedure.

[0087] The examiner can cause the first information processing device 2A to execute either indirect assistance or manual assistance in various ways. As an example, in this embodiment, it is preset so that indirect assistance is executed first when the self-eye examination assistance process is started. In addition, the indirect assistance is switched to manual assistance by inputting an operation instruction to the subjective eye examination device 1, an instruction to correct the correction value, or an instruction to skip a procedure 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-eye examination assistance screen.

[0088] If indirect assistance is being performed (S26: NO), the CPU 21A judges whether or not the answer of the subject who visually recognized the presented optotype has been input by the examiner or the subject (S27). In this embodiment, during indirect assistance, the subject can input the answer heard from the subject to the second information processing device 2B by operating the operation unit 34B connected to the second information processing device 2B. The answer input to the second information processing device 2B is transmitted to the second information processing device 2A. Therefore, even if the subject does not understand the answering method in the self-eye examination, the progress of the self-eye examination is appropriately assisted. Also, in this embodiment, even during indirect assistance, the examiner can input the answer of the result of visually recognizing the optotype by himself / herself, as in the above-mentioned S7 (see FIG. 2). Therefore, when the subject understands the answering method after receiving advice from the examiner, he / she can input the answer by himself / herself to proceed with the eye examination procedure. However, during indirect assistance, one of the first information processing device 2A and the second information processing device 2B may accept the answer.

[0089] If the answer of the examinee is not input to either the first information processing device 2A or the second information processing device 2B (S27: NO), the process proceeds directly to S38. If the answer of the examinee is input to either the first information processing device 2A or the second information processing device 2B (S27: YES), the input answer and the measurement value of the optical characteristic of the examinee's eye are stored in the storage device 22A (S28) in the same manner as in S8 (see FIG. 2). Next, the CPU 21A determines the next optotype presenting operation to be performed 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 outputs a presenting instruction signal (drive signal) for performing the determined presenting operation to the subjective optometry device 1 (S29). That is, the self-eye examination according to the progress procedure performed by the self-eye examination program is continued thereafter. After that, the process proceeds to S38.

[0090] If manual assistance is being performed instead of indirect assistance (S26: YES), the CPU 21A judges whether or not an operation instruction for the examiner to manually proceed at least a part of the procedure has been input by the examiner (S31). The examiner can determine an operation instruction for the subjective optometry device 1 (that is, at least one of an instruction for the arrangement operation of the optical element in the correction optical system 11 and an instruction for the presentation operation of the optotype in the optotype presenting unit 16) based on, for example, the display contents of the self-eye examination assistance screen (see FIG. 3) or a conversation with the examinee. In this case, the examiner inputs the determined operation instruction to the second information processing device 2B via the operation unit 34B or the like. The input operation instruction is acquired by the first information processing device 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 perform the instructed operation to the subjective optometry device 1 (S32).

[0091] Next, the CPU 21A judges whether or not an instruction to correct the correction value stored in S8 (see FIG. 2) or S28 by the self-eye examination has been input (S33). When the examiner judges that the correction value (measurement value) displayed on the self-eye examination auxiliary screen (see FIG. 3) needs to be corrected, the examiner inputs an instruction to correct the correction value that needs to be corrected to the second information processing device 2B via the operation unit 34B or the like. The inputted correction instruction is acquired by the first information processing device 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).

[0092] Next, CPU 21A judges whether or not an instruction to skip at least a part of the procedure (at least one of the multiple tests in this embodiment) has been input (S35). When the CPU 21A inputs an instruction to skip via second information processing device 2B and network 5 (S35: YES), it skips the instructed test from among the multiple tests included in the procedure from the procedure (S36). Then, the process proceeds to S38.

[0093] Next, the CPU 21A judges whether or not a series of eye examinations for the subject has been completed (S38). For example, the CPU 21A may judge that a series of eye examinations has been completed when a self-eye examination performed according to a procedure has been completed. The CPU 21A may also judge that a series of eye examinations has been completed when an instruction to end the eye examination for the subject has been input. When a series of eye examinations has been completed (S38: YES), the process ends.

[0094] Next, the CPU 21A judges whether or not a continuation / resumption instruction for the self-eye examination has been input (S39). The continuation / resumption instruction is an instruction to resume the self-eye examination from the next step of the procedure in which the eye examination has already been completed among the proceeding procedures set in S3 (see FIG. 2). For example, the CPU 21A may judge that the continuation / resumption instruction has been input when the subject operates a continuation / resumption button (not shown). When the continuation / resumption instruction is input via the second information processing device 2B and the network 5 (S39: YES), the CPU 21A sets the resumption procedure for resuming the self-eye examination to the next step of the proceeding procedures in which the eye examination has already been completed (S40), and the process returns to the eye examination control process (see FIG. 2). In the subsequent processes of S5 to S9, the self-eye examination is resumed from the resumption procedure set in S40. When the continuation / resumption instruction has not been input (S39: NO), the process proceeds directly to S42.

[0095] Next, the CPU 21A judges whether or not a designated restart instruction for the self-eye examination has been input (S42). The designated restart instruction is an instruction to restart the self-eye examination from a procedure designated by the examiner among the procedures set in S3 (see FIG. 2). In this embodiment, the examiner can input the designated restart instruction by designating a restart procedure for restarting the self-eye examination on the procedure displayed in the procedure display field 52 (see FIG. 3) of the self-eye examination auxiliary screen. As an example, in this embodiment, the examiner inputs the designated restart instruction using a mouse or a touch panel. Note that a designated restart instruction button (reset button) for erasing the results of the self-eye examination already performed according to the procedure and restarting the self-eye examination from the beginning of the procedure may be provided on the self-eye examination auxiliary screen or the like. When the designated restart instruction is input via the second information processing device 2 and the network 5 (S42: YES), the CPU 21A sets the restart procedure for restarting the self-eye examination to the procedure designated by the designated restart instruction among the procedures (S43), and the process returns to the eye examination control process (see FIG. 2). In the subsequent processes of S5 to S9, the self-eye examination is resumed from the resumption procedure set in S43.

[0096] The techniques disclosed in the above embodiments are merely examples. Therefore, it is possible to change the techniques exemplified in the above embodiments. For example, it is possible to execute only a part of the techniques exemplified in the above embodiments. As an example, the subjective eye examination system 100 of the above embodiments executes both the examiner call process (S21) and the examiner's assistance process for the self-eye examination (S23 to S43) when a problem occurs in the self-eye examination (S11: YES or S12: YES). However, the subjective eye examination system 100 may execute only one of the examiner call process and the examiner's assistance process. For example, the self-eye examination is appropriately assisted even if the examiner is only called by the examiner call process.

[0097] In the above embodiment, the self-eye examination is started in a state where the second information processing device 2B is 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 the self-eye examination (S11: YES or S12: YES).

[0098] The self-eye examination assistance process (see FIG. 4) of this embodiment is executed according to an instruction input to the second information processing device 2B arranged at a remote location. However, the self-eye examination assistance process may be executed according 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). That is, an examiner at a location where the subjective eye examination device 1 is installed may input an instruction to assist the self-eye examination. In addition, both the first information processing device 2A and the second information processing device 2B may accept input of an instruction to assist the self-eye examination. In this case, the examiner can assist the self-eye examination both at the location where the subjective eye examination device 1 is installed and at a remote location. Note that, when an instruction to assist the self-eye examination is input via the first information processing device 2A, the process of calling the examiner in S21 (see FIG. 4) may be executed in the first information processing device 2A, or may be executed in both the first information processing device 2A and the second information processing device 2B.

[0099] In addition, in S5 of FIG. 2 and SS29 of FIG. 4, the process of outputting a presentation instruction signal to the subjective eye examination device 1 based on the progress procedure is an example of a "self-eye examination progress step". The process of acquiring an answer from the subject in S7 of FIG. 2 and S27 of FIG. 4 is an example of an "answer acquisition step". The process of storing a correction value in S8 of FIG. 2 and S28 of FIG. 4 is an example of a "correction value storage step". The self-eye examination assistance process shown in FIG. 4 is an example of a "self-eye examination assistance step". The process of outputting a presentation instruction signal in response to an operation instruction in S31 and S32 of FIG. 4 is an example of a "manual progress step". The process of correcting the correction value in S33 and S34 of FIG. 4 is an example of a "correction value correction step". The process of omitting the progress procedure in S35 and S36 of FIG. 4 is an example of a "procedure omission step". The process of acquiring an answer from the subject in response to an instruction input by the examiner in S27 of FIG. 4 is an example of a "proxy answer acquisition step". The process of resuming the self-eye examination from the next procedure in S39 and S40 of Fig. 4 is an example of a "continuation restart step." The process of resuming the self-eye examination from the procedure specified by the examiner in S42 and S43 of Fig. 4 is an example of a "designated restart step." The process of resuming the self-eye examination in S33 and S34 of Fig. 4 is an example of a "self-eye examination restart step." The process of displaying the progress procedure in S24 of Fig. 4 is an example of a "procedure display step."

[0100] <Setting the inspection timing based on the call execution instruction> Hereinafter, an example of an embodiment when the examiner calling process is executed will be described. When the subject operates a help button 70 (see, for example, FIG. 5) provided on the subject controller, the CPU 21A accepts an input of a call execution instruction and executes an examiner calling operation.

[0101] <Call examiner> As the examiner calling operation, the CPU 21A may display, for example, a call display for calling the examiner on a display device (for example, at least one of the display units 35A and 35B). The display form of the call display may be, for example, at least one of a message for calling the examiner (for example, HELP display 58a in FIG. 6) and a mark for calling the examiner (for example, see mark 58b in FIG. 6). Furthermore, without being limited thereto, various transformations are possible, such as blinking the display screen and changing the background of the display screen.

[0102] In this case, the display device for displaying the call display is not limited to the display unit 35A and the display unit 35B, but may be a stationary display (display different from the display unit 35A) installed in a facility having the optometry device body, or a display of a tablet or smartphone (display different from the display unit 35A) held by a staff member in the facility. Of course, this embodiment can be applied even if the display unit is a display different from the display unit 35B used in a remote location. It goes without saying that the display device may not be a general-purpose display, but may be a display provided on an examiner's controller operated by an examiner (for example, see the examiner's controller 76 and the operation unit 34B in FIG. 5).

[0103] Furthermore, the CPU 21A may generate, as an examiner calling operation, a calling sound for calling the examiner via the sound generating unit. The form of the sound may be, for example, a sound indicative of calling the name of a specific examiner, or a sound indicative of the examiner moving to the subjective optometry device main body. Furthermore, without being limited thereto, a simple beep may be output in response to a call execution instruction.

[0104] Furthermore, the CPU 21A may output the elapsed time from the time when the call execution instruction is input (for example, see time display 59 in FIG. 6). For example, the CPU 21A may display the elapsed time together with the call display for calling the examiner. In this case, the elapsed time may be output by measuring the time from the time when the call execution instruction is input. Note that the display form of the elapsed time is not limited to a numerical display, and may be expressed, for example, by a graphic (for example, an indicator) that changes according to the elapsed time. Note that the output method is not limited to a display, and various modifications are possible. For example, the elapsed time may be output as a sound.

[0105] By outputting the elapsed time as described above, for example, the time elapsed from the time when the call execution instruction was input is visualized, which motivates the examiner to assist with the eye examination as soon as possible. In addition, the examiner providing the assistance can give appropriate words of encouragement according to the elapsed time. For example, if the time since the call execution instruction is relatively long, the examiner can say, "Sorry to have kept you waiting." In addition, the examiner can take measures such as responding to examinees who have been waiting for a long time first.

[0106] When the CPU 21A detects that the elapsed time exceeds a predetermined time, the CPU 21A may change the notification content based on the detection result. For example, when the elapsed time exceeds a predetermined time, the display form of the call display (for example, change in color, from constant lighting to blinking, etc.) may be changed. Also, when the elapsed time exceeds a predetermined time, the volume of the call sound may be increased.

[0107] In addition, when outputting the elapsed time from the time when the call execution instruction is input, the CPU 21A may be configured to output the elapsed time statistically. For example, the CPU 21A may be configured to output the elapsed time for each subject in a table format or a graph format. Also, the elapsed time for each facility and each examiner may be measured and output in a table format or a graph format. In this way, it is possible to statistically evaluate whether the call execution instruction is quickly responded to, and it is possible to encourage individual improvements through, for example, evaluation by facility or by examiner.

[0108] <Stopping the progress of self-eye examination> When the input of the call execution instruction is accepted, the CPU 21A may temporarily stop the progress of the self-eye examination at the time when the call execution instruction is input.

[0109] In this case, the CPU 21A stops the progress of the test at the test item at the time when the call execution instruction is input, for example. As an example, the CPU 21A may not accept a response from the subject from the time when the call execution instruction is input, and may not switch to the next correction value and optotype based on the self-eye examination program. This allows, for example, the test state (for example, correction value and optotype) at the time when the call execution instruction is input to be maintained, so that the examiner can smoothly perform an assisting operation. In addition, it is possible to prevent in advance the possibility that the test will proceed without resolving a problem that occurred during the self-eye examination after the call execution instruction is issued, and an erroneous test result will be obtained. In addition, the burden on the subject can be reduced, and the examiner can concentrate on the test when the examiner provides assistance.

[0110] In order not to accept an answer from the subject, for example, the CPU 21A may limit the input of an answer input from the subject controller 34A after the time when the call execution instruction is input. In this case, for example, the CPU 21A may block the input of an answer signal from the subject controller 34A, or may accept the answer signal but ignore it without involving it in the progress of the self-eye examination. In this case, it is not necessary to limit all operations of the subject controller 34A, and for example, inputs related to the subject's answer, such as an input unit (e.g., a joystick) for inputting a direction and an input unit for inputting whether or not the optotype can be seen, may be limited.

[0111] In addition, as described above, in order to prevent the correction value and optotype from being switched, the answer input may be restricted, but depending on the settings of the self-eye examination program, the CPU 21A may assume that the visual recognition is not possible if there is no answer for a certain period of time, and switch to the next correction value and optotype. In this case, by restricting the switching of the correction value and optotype from the time when the recall command is input, it is possible to prevent the examination state from changing from the time when the recall command is input.

[0112] Further, the CPU 21A may perform a distinguishing display on the display screen of the display unit that displays the call execution instruction so that the examination item at the time when the call execution instruction is input can be distinguished. For example, the CPU 21A may display the examination item at the time when the call execution instruction is input in an emphasized manner compared to other examination items (for example, see the bold frame display and arrow 53 in FIG. 6). As another method, for example, the CPU 21A may display the examination item at the time when the call execution instruction is input in association with the display of the call execution instruction. For example, the examination item may be displayed superimposed on the display indicating the call execution instruction (for example, HELP display 58a, mark 58b). Note that the display form of the distinguishing display can be changed in various ways and is not limited to the above configuration.

[0113] According to the above-mentioned discrimination display, the examiner can easily distinguish the test item at the time when the recall execution command is input, and therefore, when performing auxiliary operations by the examiner, the examiner can smoothly respond taking into account the circumstances of the test item (for example, see the auxiliary operations in the cross cylinder test mentioned above).

[0114] When the CPU 21A receives the input of the call execution instruction, the CPU 21A may display a display screen corresponding to the examination state at the time when the call execution instruction is input on a display device (for example, at least one of the display unit 35A, the display unit 35B, and the display of the examiner controller 76) (for example, see FIG. 3). This allows the examiner to check the correction value and optotype at the time when the call execution instruction is input, in addition to the examination item at the time when the call execution instruction is input, and therefore allows the examiner to smoothly take measures (for example, selection of the correction value and optotype) when performing eye examination assistance.

[0115] In addition, when the progress of the self-eye examination is temporarily stopped, the CPU 21A can immediately avoid the progress of the self-eye examination by immediately stopping the progress of the self-eye examination when the input of the call execution instruction is received. However, this is not limited to this. For example, the CPU 21A may stop the progress of the self-eye examination after a predetermined time has elapsed from the time when the input of the call execution instruction is received. In this case, the CPU 21A may stop the progress of the self-eye examination when, for example, a response is received from the examiner controller (for example, see the examiner controller 76 and the operation unit 34B in FIG. 5) within a predetermined time from the time when the input of the call execution instruction is received. In addition, the above-mentioned predetermined time may be appropriately set in consideration of the program contents, examination items, etc. of the self-eye examination.

[0116] In addition, the CPU 21A may display on the optotype presenting unit a message indicating that the call execution instruction is being made at the time when the call execution instruction is input. This allows the subject to easily understand that the examiner is being called.

[0117] <Assistive actions by examiner> When the input of the call execution instruction is accepted, the CPU 21A may release the restriction on the input from the examiner's controller (e.g., the examiner's controller 76, the operation unit 34B). In this case, the CPU 21A may restrict at least a part of the operation input from the examiner's controller until the call execution instruction is input, and release the restriction on the operation input from the examiner's controller when the call execution instruction is input.

[0118] When restricting at least a part of the operation input, at least one of the operation input from the examiner for operating at least one of the correction optical system 11 or the optotype presenting unit 16, and the answer input of the subject by the examiner may be restricted. When restricting the input, the input signal from the operation unit operated by the subject may be blocked, or the answer itself may be accepted but not involved in the progress of the self-eye examination (ignored).

[0119] By restricting the operation input of the examiner's controller until the call execution instruction is input, the operation from the examiner's controller is invalidated during the progress of the self-eye examination. This makes it possible to prevent, for example, the examiner from accidentally operating the examiner's controller, inputting an answer contrary to the procedure of the self-eye examination program, or switching the correction value, optotype, etc. In this case, it is not necessarily necessary to restrict all operations of the examiner's controller, and for example, the input unit for receiving the input of forced assistance for forcibly performing assistance by the examiner, the input unit for giving advice to the examinee by voice, text, etc., etc. do not necessarily need to be restricted even at a stage before the call execution instruction is input.

[0120] When the call execution instruction is input, the restriction on the operation input from the examiner's controller is released, and the operation of the examiner's controller becomes valid. This enables the examiner to operate the examiner's controller to assist the examinee in the eye examination. For example, the examiner can input the examinee's verbal response to the examiner's controller, change the optotype, or change the correction value.

[0121] When the CPU 21A receives the input of the call execution instruction, the CPU 21A immediately releases the restriction on the operation input from the examiner's controller, thereby enabling the eye examination assistance to be performed quickly. However, this is not limited to this. For example, the CPU 21A may release the restriction on the operation input from the examiner's controller after a predetermined time has elapsed since the input of the call execution instruction was received. Furthermore, the CPU 21A may release the restriction on the operation input from the examiner's controller when, for example, there is a response from the examiner's controller indicating that the eye examination assistance is available.

[0122] The procedure for the examiner to perform the assisting operation is, for example, a notification operation for calling the examiner, and when the examiner is ready to perform the eye examination assistance for the subject, the examiner operates a response switch for the eye examination assistance. When the response switch is pressed, the CPU 21A ends the examiner calling operation. As the response switch, the mark 58b may also be used as the response switch as shown in FIG. 6, and when the mark 58b is touched, a response signal by the examiner may be input. Of course, the form of the response switch is not limited to this, and a physical switch may be provided.

[0123] The examiner may operate the examiner's controller while viewing a display screen of a display device (e.g., at least one of the display unit 35A, the display unit 35B, and the display of the examiner's controller 76) used by the examiner to assist the examinee. For example, the CPU 21A may cause the display device to display a flow in which a plurality of examination items based on the self-eye examination program are arranged (see, for example, FIG. 6). For example, the examiner can easily select the examination item for which eye examination assistance is to be performed by selecting a desired examination item on the display screen using the examiner's controller. This enables the examiner to perform an examination using the selected examination item.

[0124] In the above-described self-eye examination assistance step, the CPU 21A stops the progress of the self-eye examination at the time when the call execution instruction is input, thereby maintaining the examination item at the time when the call execution instruction is input. As a result, the CPU 21A can set the examination timing for the examination item at the time when the call execution instruction is input. Note that, by using the discrimination display related to the examination item at the time when the call execution instruction is input, the examiner can easily select the examination item at the time when the call execution instruction is input as the examination item for which eye examination assistance is performed. As a result, the examination timing is set for the examination item at the time when the call execution instruction is input.

[0125] In this case, the eye examination assistance can be performed from the examination item that was stopped at the time when the recall execution instruction was input, so that the eye examination assistance can be performed for the examination item for which there is a high possibility that some problem occurred during the self-eye examination. Therefore, for example, the examiner can easily trace the memory of the examinee regarding the examination at the time when the recall execution instruction was issued. In other words, if the examinee does not know how to answer the examination item, the examiner can provide supplementary explanations on the answering method, and if the optotype cannot be seen at all, the examiner can give advice on how to look into the examination window, etc. In addition, if the correction value is significantly different from the subject's subjective value, it is also possible to adjust the correction value.

[0126] On the other hand, if the self-examination proceeds after the call execution instruction is input, there is a possibility that the examination will be shifted to another examination different from the examination item in which some problem is likely to have occurred, and it may not be possible to appropriately deal with the examination item in which the problem occurred. In addition, it is assumed that the examination will proceed further in the examination item in which some problem is likely to have occurred, and the correction value will be significantly different from the subject's appropriate subjective value, and it will take more time than necessary to properly complete the examination. In response to this, the possibility of such problems occurring can be avoided in advance by setting the eye examination timing by pausing.

[0127] In the above embodiment, even if the selection operation of the test item is not performed, the test may be started by the examiner. For example, the CPU 21A may display a display screen corresponding to the test state at the time when the call execution instruction is input on a display device (for example, at least one of the display unit 35A, the display unit 35B, and the display of the examiner's controller 76), and may accept the input of an answer or change the optotype and correction value based on an operation signal from the examiner's controller.

[0128] <Example of transformation> In the above embodiment, the progress of the self-eye examination is temporarily stopped when the call execution instruction is input, thereby setting the examination timing to the examination item at the time when the call execution instruction is input, but this is not limited to this. For example, in the self-eye examination assistance step, the examination item at the time when the call execution instruction is input may be stored in the storage device 22A, and the examination timing may be set to the examination item at the time when the call execution instruction is input based on the examination item at the time when the call execution instruction is input stored in the storage device 22A.

[0129] For example, the CPU 21A may store the examination items at the time when the call execution instruction is input in the storage device 22A, and may perform a discrimination display on the display device (for example, at least one of the display unit 35A, the display unit 35B, and the display of the examiner's controller 76) so that the examination items at the time when the call execution instruction is input can be distinguished based on the examination items at the time when the call execution instruction is input stored in the storage device 22A. The examiner can set the examination timing to the examination items at the time when the call execution instruction is input based on the discrimination display. Furthermore, when the CPU 21A receives a predetermined operation input from the examiner, the CPU 21A may display the examination items on the display device (for example, at least one of the display unit 35A, the display unit 35B, and the display of the examiner's controller 76) based on the examination items at the time when the call execution instruction is input stored in the storage device 22A.

[0130] Furthermore, even if the examination timing is not set based on the above screen display, when assistance is provided to the subject based on an operation signal from the examiner controller, the CPU 21A may automatically set the examination timing to the examination item at the time when the call execution instruction is input, based on the examination item at the time when the call execution instruction is input, which is stored in the memory device 22A.

[0131] In the above modification example, the progress of the self-eye examination may be continued without stopping once the call execution instruction is input. In this case, if the examination is performed properly, more test results may be obtained before the examiner's assistance begins, and the overall examination time may be shortened. However, since there is a possibility of obtaining erroneous test results, it is advisable to consider whether or not to perform this, taking into account the difficulty of the examination, etc.

[0132] In the above embodiment, the optotype and correction value are set at the time when the instruction to execute the call is input, but this is not limited to this. By setting the optotype and correction value corresponding to the examination item at the time when the instruction to execute the call is input, it is possible to smoothly assist with the eye examination.

[0133] For example, the CPU 21A may set the optotype and correction value at the start of the test for the test item at the time when the recall command is input. In this case, the CPU 21A may set the optotype and correction value at the start of the test by storing the optotype and correction value at the start of the test in the storage device 22A in advance. This allows, for example, if the test is performed inappropriately at the time when the recall command is input, to reset the test once and perform the test from the start of the test, which results in the test being performed smoothly. Such control is advantageous, for example, in the case where the correction value is significantly different from the subject's subjective value due to the subject's self-test.

[0134] The optotype and correction value at the start of the test do not necessarily have to be completely the same, and may be, for example, a different test optotype with the same visual acuity value as at the start of the test, and the correction value may also be the same in spherical power as at the start of the test, but different in astigmatism axis and astigmatism axis angle from those at the start of the test. Similarly, when setting the optotype and correction value at the time when the recall execution instruction is input, they do not necessarily have to be completely the same.

[0135] Before the call execution instruction is input, a monitoring screen for the examiner to monitor the progress of the self-eye examination (e.g., the presented optotype, the correction value, the answer content, etc.) may be displayed on the display device (e.g., at least one of the display unit 35A, the display unit 35B, and the display of the examiner controller 76). For example, the examiner can easily grasp the progress of the self-eye examination by constantly monitoring the presented optotype and the correction value. In addition, the answer content of the examinee is displayed, so that the examiner can easily grasp whether the answer status of the examinee is appropriate or not. Furthermore, when the call execution instruction is input, a call display for calling the examiner may be performed on the monitoring screen. According to this, the examination timing is set for the examination item at the time when the call execution instruction is input, and when the eye examination is assisted, the examiner can start assisting the examinee with the eye examination after grasping the progress of the self-eye examination in advance, so that more appropriate assistance can be provided.

[0136] In the above embodiment, the timing of the test to start the auxiliary operation is set to the test item at the time when the call execution instruction is input, but the timing of the test to start the auxiliary operation may be set to a test item different from the test item at the time when the call execution instruction is input. For example, in a self-eye examination, if a call execution instruction is input during an astigmatism axis test in a cross cylinder test, it may be better to start the test with an astigmatism degree test in a cross cylinder test as an auxiliary operation by the examiner. In this case, a flow in which a plurality of test items based on a self-eye examination program are arranged is displayed, and a desired test item (e.g., an astigmatism degree test in a cross cylinder test) is selected on the display screen using the examiner's controller, so that the examiner can smoothly perform the auxiliary operation.

[0137] In the above description, the instruction to call is to execute a call operation to call the examiner, but it may be an instruction to call an assistant. The assistant may be, for example, an examiner who performs a subjective test, a staff member who does not perform the test, or an attendant of the examinee. Even when a call is made to the staff member or an attendant, since a notice is issued that assistance with the eye examination is required, an examiner who can perform the subjective test can be called through the staff member. In addition, even the staff member can be expected to give some advice, such as adjusting the positional relationship between the eye examination device main body and the examinee.

[0138] In the above description, when the call execution instruction is input, the examination timing is set to the examination item at the time when the call execution instruction is input, but this is not limited to this. For example, when the situation of the self-eye examination being performed satisfies a predetermined condition, the CPU 21A may set the examination timing to the examination item at the time when the situation of the self-eye examination being performed satisfies the predetermined condition. This makes it possible to smoothly assist the examinee in the eye examination from the examination item at the time when the condition that determines that some problem has occurred is satisfied.

[0139] In the above description, after the call execution instruction is input, the input of the answer by the subject from the subject controller is restricted, but the present invention is not limited to this, and when the examiner assists in the eye examination, the restriction on the input of the answer by the subject from the subject controller may be lifted by receiving an input of lifting the restriction from the examiner controller. In this case, the examiner can train the subject on how to input answers and check whether the answer input is appropriate, and then resume the suspended self-eye examination.
