Disclosure of Invention

Problems to be solved by the invention

In a conventional subjective refraction device, an examiner needs to examine a subject on site, and a drive instruction for the next operation of the subjective refraction device is input based on a response from the subject visually recognizing an inspection visual target. Therefore, it is difficult for the conventional subjective refraction device to smoothly perform subjective refraction while reducing the burden on the inspector.

A typical object of the present disclosure is to provide an subjective refraction control program and an subjective refraction system capable of more smoothly performing subjective refraction.

An optotype control program provided by an exemplary embodiment of the present disclosure is executed by a first information processing device of an subjective refraction system including an subjective refraction device for subjective measurement of an optical characteristic of an eye to be inspected and a first information processing device connected to the subjective refraction device, and includes a self-refraction application program for realizing an application of automatically advancing an optotype based on a response input by an examinee, the first information processing device executing the self-refraction application program by the control section of the first information processing device, the first information processing device including: a self-refraction advancing step of outputting a presentation instruction signal to the subjective refraction device based at least on an advancing process of self-refraction that advances automatically, the presentation instruction signal being for instructing a presentation action of presenting a visual target to a subject; a reply acquiring step of acquiring a reply input by a subject visually recognizing the presented optotype; a correction value storage step of storing a correction value of the optical characteristics of the eye to be inspected acquired based on the answer acquired in the answer acquisition step and the optical characteristics of the optotype and optotype beam presented by the subjective refraction device at the time of acquiring the answer; and a self-refraction assisting step of performing an assisting action for assisting the self-refraction in the case where a problem occurs in the self-refraction.

An subjective refraction system according to an exemplary embodiment of the present disclosure includes a subjective refraction device having a corrective optical system for changing an optical characteristic of a target light beam to be presented to an eye to be inspected and a target presentation unit for presenting a target to the eye to be inspected, and a first information processing device connected to the subjective refraction device, wherein the first information processing device has a self-refraction application for automatically advancing refraction based on a response input by the person to be inspected, the self-refraction application performing the steps of: a self-refraction advancing step of outputting a presentation instruction signal to the subjective refraction device based at least on an advancing process of self-refraction that advances automatically, the presentation instruction signal being for instructing a presentation action of presenting a visual target to a subject; a reply acquiring step of acquiring a reply input by a subject visually recognizing the presented optotype; a correction value storage step of storing a correction value of the optical characteristics of the eye to be inspected acquired based on the answer acquired in the answer acquisition step and the optical characteristics of the optotype and optotype beam presented by the subjective refraction device at the time of acquiring the answer; and a self-refraction assisting step of performing an assisting action for assisting the self-refraction in the case where a problem occurs in the self-refraction.

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

The subjective refraction system illustrated in the present disclosure includes a subjective refraction device and a first information processing device. The subjective refraction device has a correction optical system for changing the optical characteristics of a target light beam to be presented to an eye to be inspected, and a target presentation unit for presenting a target to the eye to be inspected, and is used for measuring the optical characteristics of the eye to be inspected. The first information processing apparatus is an information processing apparatus connected to the subjective refraction apparatus (hereinafter, the first information processing apparatus may be referred to as a "connection apparatus"). The refraction control program to which the present disclosure relates includes a self-refraction application. The self-refraction application program is a program for realizing an application (self-refraction application) that automatically advances refraction based on a reply input by a subject.

The self-refraction advancing step, the reply acquiring step, the correction value storing step, and the self-refraction assisting step are executed by the first information processing apparatus by executing the self-refraction application program by the control section of the first information processing apparatus. In the self-refraction advancing step, the first information processing apparatus sequentially outputs a plurality of presentation instruction signals for instructing a presentation action of presenting the optotype to the subject to the subjective refraction apparatus based on at least the advancing process of the self-refraction that advances automatically (that is, in accordance with the advancing process). In addition, in the self-refraction advancing step, the first information processing apparatus may control the correction optical system and the optotype presenting section based on the advancing process of the self-refraction that advances automatically to execute a plurality of examination items. In the answer acquiring step, the first information processing apparatus acquires an answer input by a subject visually recognizing the presented optotype. In the correction value storing step, the first information processing apparatus stores correction values of optical characteristics of the eye to be inspected acquired based on the reply acquired in the reply acquiring step and the optical characteristics of the optotype and optotype beam presented by the subjective refraction apparatus at the time of acquiring the reply. In the self-refraction assisting step, in the case where a problem occurs in the progress of self-refraction, the first information processing apparatus performs an assisting action for assisting the progress of self-refraction.

According to the subjective refraction system according to the present disclosure, by executing the self-refraction application, the examiner can appropriately perform the refraction of the examinee even without advancing the refraction. In addition, when a problem occurs in the self-refraction progress, an assist operation for assisting the self-refraction progress is performed. That is, among the functions of the self-refraction application, a function of assisting the advancement of self-refraction is assembled. Thus, for example, during execution of the self-refraction application, at least any one of the auxiliary actions of self-refraction based on advice or the like from the inspector is performed. Accordingly, subjective refraction is appropriately performed in a state in which the burden on the examiner is reduced.

Further, as the first information processing apparatus that executes the optometry control program, various devices can be used. For example, a personal computer (hereinafter referred to as "PC") may be used as the first information processing apparatus. In addition, a server, a portable terminal, a smart phone, or the like may be used as the first information processing apparatus.

The first information processing apparatus may be configured by combining a plurality of devices. For example, the first information processing apparatus may be configured by a device such as a personal computer, or a dedicated controller including a controller and a storage device. Of course, the first information processing apparatus may be configured by providing the dedicated controller itself with a function as a device such as a personal computer having a CPU.

In addition, a storage device for storing the refraction control program may be appropriately selected. For example, the optometry control program may be stored in a storage device incorporated in the first information processing device or may be stored in a storage device detachable from the first information processing device. The refraction control program may also be stored in a memory device built into the dedicated controller. In addition, the refraction control program may be stored in a plurality of storage devices.

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

The condition of the self-refraction condition at the time of performing the assist operation can be appropriately selected. For example, the control unit may determine that the execution condition of the assist operation is satisfied when the predetermined time has elapsed without inputting a response from the subject. The control unit may determine that the execution condition of the assist operation is satisfied when the answer input by the subject is not appropriate. The method for determining whether or not the answer is inappropriate can be appropriately selected. For example, when the input answer does not satisfy the predetermined answer condition (for example, when an answer different from the answer candidate requested for the subject is input, when the same answer is continuously input a predetermined number of times or more, or when an answer more than the number of times of the answer requested for the subject is input, etc.), the control unit determines that the input answer is not appropriate.

The assisting action performed in the self-refraction assisting step may include a calling action of calling the inspector. In this case, since the inspector is called when a problem occurs in the progress of self-refraction, the following refraction can be properly performed.

The self-refraction assisting step may also include a manual pushing step in which a presentation instruction signal for pushing at least a part of the pushing process is outputted to the subjective refraction device according to an instruction inputted by the examiner. In this case, the inspector can manually advance the inspection or the like in which the problem has occurred in the advance process scheduled to advance through self-refraction. Therefore, the refraction of the subject can be more appropriately assisted.

The self-refraction assisting step may also include a correction value correcting step in which at least any one of the one or more correction values stored through the self-refraction is corrected in accordance with an instruction input by the examiner. In this case, even when there is a correction value obtained by failure of the self-refraction measurement, for example, the correction value can be corrected by the judgment of the inspector. Therefore, the optometry of the subject is smoothly advanced.

The self-refraction assistance step may also include a test omission step in which at least a part of the advancing process is omitted according to an instruction input by the inspector. In this case, the inspector can omit a process determined to be unnecessary among predetermined progress processes. Therefore, the optometry of the subject is smoothly advanced.

The method for inputting the instruction of the inspector to omit at least a part of the advancing process can be appropriately selected. For example, the inspector may input, to the first information processing apparatus, a selection instruction of a test to be omitted among a plurality of tests executed according to the progress process. In this case, the control unit of the first information processing apparatus may omit the selected test from the progress. The inspector may input the timing to restart the self-refraction that is temporarily stopped to the first information processing apparatus as a timing later than the process to be omitted. In this case, the control unit of the first information processing apparatus may omit a part of the process by restarting the self-refraction from the input timing.

The self-refraction assistance step may also include a proxy reply acquisition step. In the proxy reply acquisition step, the control section acquires a reply of the subject visually recognizing the presented optotype based on an instruction input by the examiner when the optotype is presented to the subject in accordance with the progress of the self-refraction advancing step. In this case, the examiner can listen to the responses from the examinee visually recognized on the visual target and personally input the listened responses while sequentially presenting the visual target to the examinee in accordance with the progress of self-optometry. Thus, even in the case where the subject does not grasp the reply method or the like in self-refraction, the examiner can appropriately assist self-refraction by inputting the reply heard from the subject.

The self-refraction assisting step may include a continuation and restart step in which the temporarily stopped self-refraction is restarted from the next process of the progress of the refraction (for example, the completed test or the like) in the progress. In this case, the self-refraction is restarted from the next one of the already completed processes in the advancing process. Therefore, even after the end of the self-refraction assistance, the self-refraction can be continued appropriately in accordance with the advancing process.

The self-refraction assisting step may include a designation restarting step of restarting the temporarily stopped self-refraction from a process designated by the inspector (for example, a designated test or the like) during the advancing process. In this case, the inspector can restart the self-refraction from the process specified by the inspector, with the problem or the like occurring in the self-refraction eliminated. Therefore, an excessive increase in the burden on the inspector for assisting optometry can be suppressed.

In the progress of self-refraction, a plurality of tests (examinations) to be performed on the subject and the execution order of the plurality of tests may be determined. In the self-refraction advancing step, a plurality of tests may also be performed sequentially according to the advancing process. In this case, a plurality of tests for the eye to be inspected are appropriately automatically advanced. The inspector can appropriately assist a test (e.g., a test in which a good correction value is not obtained in self-refraction) that is determined to be necessary among the plurality of tests.

The self-refraction assisting step may also include a process display step of displaying the advancing process on the display device. The display device may be disposed at a point on which the examiner waits, and may be disposed at a point different from the point on which the subjective refraction device is disposed, or at the same point as the point on which the subjective refraction device is disposed. In the designating restarting step, an input of a designating instruction for instructing a process of restarting the self-refraction (hereinafter referred to as "restarting process") on top of the advancing process displayed by the display device may be accepted. In this case, the inspector can specify a restart process for restarting the self-refraction in a state where the details of the progress process, the progress status, and the like are appropriately grasped from the displayed progress process.

Further, as for a specific method for accepting an input indicating to start the process again on top of the displayed advancing process, it is possible to appropriately select. For example, a touch panel may be provided in a display region of the display device. In this case, the control unit may process a procedure (for example, a specific test or the like) corresponding to the position where the touch panel is operated in the displayed progress procedure as a restart procedure designated by the inspector. In addition, a mouse or the like for moving the pointer in the display area of the display device may be provided. In this case, the control unit may process a procedure corresponding to the position of the pointer above the displayed progress procedure as a restart procedure designated by the inspector.

In addition, the control portion may display the entire pushing process above the pushing process (for example, a plurality of tests included in the progress process, etc.), and a process that is being performed at that point in time, a process that is being performed when a problem occurs in the progress, etc. In this case, the inspector can appropriately grasp the progress of self-refraction through the displayed progress of progress.

As described above, by restarting the self-refraction that is temporarily stopped, various advantages are produced. For example, in a cross cylindrical lens test, which is one of tests performed by an subjective refraction system, two point groups are presented to a subject. However, if the relative position between the inspection window of the corrective optical system and the eye to be inspected deviates, the subject may only visually recognize one of the two dot groups. In this case, the subject cannot perform self-refraction. However, according to the subjective refraction system of the present disclosure, the examiner can make advice or the like to adjust the position of the eye to be examined with respect to the inspection window while temporarily stopping the self-refraction, and assist in performing the cross cylindrical lens test, and then restart the self-refraction performed by the examinee alone. In this way, when the self-refraction that is temporarily stopped is restarted, an effect that is useful for both the examiner and the examinee can be obtained.

The self-refraction assistance step may be performed in accordance with an instruction input to a second information processing apparatus, which is another information processing apparatus connected to the first information processing apparatus via a network. In this case, even when the examiner is located at a distance different from the location of the examiner, the examiner can appropriately assist the self-refraction of the examiner from a distance by inputting an instruction to the second information processing apparatus.

In addition, when a problem occurs in the progress of self-refraction (for example, when an instruction to execute an auxiliary operation is input), the control unit of the first information processing apparatus may output an instruction to execute a calling operation for calling the inspector to the second information processing apparatus. In this case, even when the examiner is located at a distance different from the location of the subject, the examiner can easily grasp that a problem has occurred in the progress of self-refraction.

However, the self-refraction assisting step may be performed in accordance with an instruction directly input to the first information processing apparatus (for example, an instruction input to the operation section of the first information processing apparatus). That is, the instruction for executing the self-refraction assisting step may be input by an inspector located at a place where the subjective refraction device and the first information processing device are provided. In this case, for example, the operation unit (inspector controller) of the first information processing apparatus for inputting an instruction from an inspector may be a dedicated controller provided in the subjective refraction device or may be a general-purpose user interface such as a mouse or a tablet computer.

In the case of using the second information processing apparatus, the number of the second information processing apparatuses may be one or two or more. In addition, as with the first information processing apparatus, various devices (for example, a PC, a portable terminal, a smart phone, or the like) can be used for the second information processing apparatus. The second information processing apparatus may be connected to the first information processing apparatus already at the time of performing self-refraction, or may be connected to the first information processing apparatus after a problem occurs in self-refraction.

In the case of using the second information processing apparatus, the control unit of each of the first information processing apparatus and the second information processing apparatus may execute a remote dialogue step in which a dialogue between the examiner and the examinee is assisted by transmitting and receiving at least sound data (both of sound data and image data may be used) to each other. In this case, the remotely located inspector can grasp the condition of the subject by a dialogue, thereby being able to appropriately assist in self-refraction.

Detailed Description

(System architecture)

One of the exemplary embodiments of the present disclosure is described below with reference to the accompanying drawings. As shown in fig. 1, subjective refraction system 100 of the present embodiment includes subjective refraction device 1 and first information processing device 2A. The subjective refraction device 1 is used to measure the optical characteristics of the eye to be examined. The optical characteristic of the eye to be inspected measured by the subjective refraction device 1 of the present embodiment is the eye refractive power. The measured ocular refractive power may be at least one of sphere power, cylinder power, and astigmatism axis angle of the eye to be inspected. The first information processing device 2A is connected to the subjective refraction device 1. Hereinafter, the first information processing apparatus 2A is also sometimes referred to as a connection apparatus. The first information processing apparatus 2A is connected to a second information processing apparatus 2B, which is another information processing apparatus, via a network 5. That is, the first information processing apparatus 2A of the present embodiment is sometimes remotely accessed by the second information processing apparatus 2B. Next, each device will be described in detail.

The subjective refraction device 1 will be described. The subjective refraction device 1 includes an eye refractive power measurement unit 10, a visual target presentation unit 15, and a relay unit 19.

The ocular refractive power measurement unit 10 includes a correction optical system 11 and a driving unit 12. The correction optical system 11 changes the optical characteristics of the optotype beam to be presented to the eye to be inspected. That is, the correction optical system 11 changes at least one of the sphere power, cylinder power, astigmatism axis angle, polarization characteristic, and aberration amount of the optotype beam. As an example, the correction optical system 11 of the present embodiment changes the optical characteristics of the optotype beam by switching the optical element of the inspection window placed in front of the eye to be inspected among the plurality of optical elements. In the correction optical system 11 of the present embodiment, a left-eye lens disc and a right-eye lens disc in which a plurality of optical elements are arranged on the same circumference are used. The left-eye lens disk and the right-eye lens disk may each be one or more pieces. For example, at least one of a spherical lens, a cylindrical lens, a crossed cylindrical lens, a rotating prism, a wavefront modulation element, and the like may be used as the optical element. The driving unit 12 drives the correction optical system 11 to change the optical characteristics of the optotype beam. The driving unit 12 of the present embodiment drives the corrective optical system 11 by rotating the left-eye lens disk and the right-eye lens disk, respectively, to switch the optical elements disposed in the inspection window. For the driving unit 12, a stepping motor or the like can be used, for example. The driving unit 12 drives in accordance with the driving signal.

The optotype presenting unit 15 presents an inspection optotype (for example, at least any one of a langerhans optotype and characters, etc.) to the eye to be inspected, and switches the inspection optotype presented to the eye to be inspected. Specifically, the optotype presenting unit 15 includes an optotype presenting unit 16 and a driving unit 17. The optotype presenting unit 16 presents an inspection optotype to the eye to be inspected. The target presentation unit 16 may be at least one of a space-saving target projection device that projects the inspection target onto the eye to be inspected via a concave mirror, a chart projector that projects the inspection target onto a screen, and a display that displays the inspection target. The optotype presenting unit 16 is disposed at a height position substantially equal to the height position of the eye refractive power measuring unit 10 so that the distance from the eye to be inspected is a predetermined optical distance. The driving unit 17 switches the examination optotype presented to the eye to be examined by driving the optotype presenting unit 16. The driving unit 17 drives the vehicle according to the driving signal.

The relay unit 19 relays the drive signal between the first information processing apparatus 2A and the drive units 12 and 17. In the present embodiment, the system of the drive signal outputted from the first information processing apparatus 2A is different from the system capable of controlling the drive signal of at least one of the drive units 12 and 17. The relay unit 19 of the present embodiment converts the drive signal received from the first information processing apparatus 2A into a drive signal capable of controlling the drive units 12 and 17, and transmits the drive signal to the drive units 12 and 17. As an example, when receiving one drive signal for driving the two drive units 12 and 17 together from the first information processing apparatus 2A, the relay unit 19 of the present embodiment converts the received one drive signal into two drive signals for driving the two drive units 12 and 17, and transmits the two drive signals to the two drive units 12 and 17, respectively.

The first information processing apparatus 2A and the second information processing apparatus 2B will be described. At least one of various information processing apparatuses capable of processing various information can be employed for the first information processing apparatus 2A and the second information processing apparatus 2B. As an example, a personal computer (hereinafter, referred to as "PC") is used for the first information processing apparatus 2A and the second information processing apparatus 2B of the present embodiment. However, the information processing apparatuses that can function as the first information processing apparatus 2A and the second information processing apparatus 2B of the present embodiment are not limited to PCs. For example, a server, a mobile terminal, a smart phone, or the like may be used as at least one of the first information processing apparatus 2A and the second information processing apparatus 2B. At least one of the first information processing apparatus 2A and the second information processing apparatus 2B may be constituted by a plurality of devices. For example, the first information processing apparatus 2A may be configured by a dedicated controller including a controller and a storage device, and a personal computer.

The first information processing apparatus 2A and the second information processing apparatus 2B are connected in a communicable state via a network (for example, the internet or the like) 5. In the example shown in fig. 1, a case is illustrated in which a plurality of second information processing apparatuses 2B are connected to one first information processing apparatus 2A. However, one second information processing apparatus 2B may be connected to one first information processing apparatus 2A. Further, one second information processing apparatus 2B may be connected to a plurality of first information processing apparatuses 2A.

The first information processing apparatus 2A is disposed at a point (for example, a spectacle store, a hospital, or the like) where subjective refraction is performed on the subject. The first information processing apparatus 2A includes a CPU 21A and a storage device 22A. The CPU 21A is a control section (controller) responsible for controlling the first information processing apparatus 2A. The storage device 22A can store programs, various data, and the like. In the present embodiment, the refraction control program is stored in the storage device 22A.

The first information processing apparatus 2A is connected to the subjective refraction device 1 (specifically, the relay unit 19 of the subjective refraction device 1) in a communicable state. As the connection standard between the first information processing apparatus 2A and the subjective refraction device 1, various standards such as LAN can be adopted. The first information processing apparatus 2A is connected to the tale type optometry apparatus 3 in a communicable manner. The objective lens device 3 measures optical characteristics (for example, at least one of sphere power, cylinder power, and astigmatism axis angle) of the eye to be inspected in an objective manner. As the connection standard of the first information processing apparatus 2A and the tale type optometry apparatus 3, various standards such as LAN can be adopted. The tale type optometry device 3 may be connected to the relay unit 19. The measurement result of the tale-type optometry device 3 may be stored in a storage device provided in the relay unit 19.

The first information processing apparatus 2A is connected to the video camera 31A, the microphone 32A, the speaker 33A, the operation unit 34A, and the display unit 35A. The camera 31A captures an image. In particular, the video camera 31A of the present embodiment captures a moving image of the subject. The microphone 32A converts sound into a sound signal and outputs the sound signal. The speaker 33A converts the sound signal into sound. The operation unit 34A is operated by a user to input various instructions by the user (for example, a subject). The operation unit 34A may use at least one of a keyboard, a mouse, a touch panel, and the like. As the operation unit 34A, a dedicated operation unit (for example, a joystick) suitable for inputting a response of subjective refraction may be used. The display section 35A displays various images. As the display unit 35B, various devices (for example, at least one of a monitor, a display, and a projector) capable of displaying an image can be used.

The second information processing device 2B is disposed at a point where an inspector (for example, a clerk, doctor, nurse, or the like who is proficient in an eyeglass shop for performing an optometry by the subjective refraction device 1) can advance the optometry by the subjective refraction device 1. The second information processing apparatus 2B includes a CPU 21B and a storage device 22B. The CPU 21B is a control section (controller) responsible for controlling the second information processing apparatus 2B. The storage device 22A can store programs, various data, and the like.

The second information processing apparatus 2B is connected to the video camera 31A, the microphone 32A, the speaker 33A, the operation unit 34A, and the display unit 35A. As for these devices, various devices can be used as in the case of the device connected to the first information processing apparatus 2A.

(application/optometry method)

An application installed in the first information processing apparatus 2A of the present embodiment will be described. As described above, the storage device 22A provided in the first information processing device 2A stores an optometry control program for executing optometry control processing (see fig. 2). Among the refraction control programs are a drive control application program for executing the drive control application and a self-refraction application program for executing the self-refraction application. The drive control application transmits a control signal for controlling the driving of the subjective refraction device 1 to the subjective refraction device 1. The self-refraction application automatically advances refraction with subjective refraction device 1 based on the answer input by the subject. In addition, the drive control application program for executing the drive control application and the self-refraction application program for executing the self-refraction application may be prepared in a separately constructed manner or may be assembled into one program.

A subjective refraction method that can be executed by the subjective refraction system 100 according to the present embodiment will be described. Subjective refraction system 100 of the present embodiment is capable of performing self-refraction and remote refraction. Self-refraction is refraction performed by a self-refraction application. That is, in the case of self-refraction, refraction is automatically advanced based on a response input by the subject basically. In addition, in the subjective refraction system 100 of the present embodiment, when a problem occurs in the progress of self-refraction, a self-refraction assisting process for assisting the progress of self-refraction is performed. The self-refraction assistance process can also be performed according to the instruction signal input to the second information processing apparatus 2B at the remote place. Thus, even when a problem occurs in the progress of self-refraction, refraction is easily and smoothly performed. The remote optometry is an optometry performed based on the instruction signal input to the second information processing apparatus 2B. In the following, a description of self-refraction will be focused.

(optometry control process)

An example of the refraction control process executed by the first information processing device 2A of the subjective refraction system 100 according to the present embodiment will be described with reference to fig. 2 to 4. In the refraction control process, for example, a process for controlling self-refraction, a process for assisting self-refraction, and the like are performed. When an instruction to start subjective refraction of the eye to be inspected is input to the first information processing apparatus 2A, the CPU 21A of the first information processing apparatus 2A executes refraction control processing illustrated in fig. 2 in accordance with a refraction control program.

As an example, the refraction control process according to the present embodiment is executed in a state where one or a plurality of second information processing apparatuses 2B establish communication (for example, remote access or the like) with the first information processing apparatus 2A. However, communication between the first information processing apparatus 2A and the second information processing apparatus 2B may be established during execution of the optometry control process (for example, at the start of the self-optometry assisting process shown in fig. 4 or the like). In addition, the communication method between the first information processing apparatus 2A and the second information processing apparatus 2B can also be appropriately selected. For example, the remote access of the second information processing apparatus 2B to the first information processing apparatus 2A may also be established by utilizing an RAS (remote access service).

First, the CPU 21A acquires an optometry result based on the tale formula (S1). As an example, the first information processing apparatus 2A of the present embodiment acquires the result of the tac-type refraction for the same subject from the tac-type refraction apparatus 3 (see fig. 1) connected via the LAN, the relay unit 19, or the like. However, the CPU 21A may acquire, for example, an objective refraction result for the same subject via a detachable memory, the network 5, or the like. The subjective refraction result may be input by the user via the operation unit 34A or the like. In the case where there is no subjective refraction result for the same subject, the process of S1 may be omitted.

Next, the CPU 21A sets a self-refraction advancing process (S3). Fig. 3 shows a part of an example of the progress of self-refraction used in subjective refraction system 100 according to the present embodiment (in fig. 3, only the progress of the right eye) in progress display field 52. As illustrated in fig. 3, the progress procedure used in the present embodiment determines a plurality of tests (a plurality of checks) to be performed on the subject and an execution order of the plurality of tests. As an example, in the advancing process shown in fig. 3, after R/G test (S), cross cylindrical lens test (a), cross cylindrical lens test (C), R/G test, and VA test are performed on the right eye of the subject, R/G test (S), cross cylindrical lens test (a), cross cylindrical lens test (C), R/G test, and VA test are performed on the left eye of the subject. In the R/G test (S), the sphere power of the eye to be inspected is measured. In the cross cylindrical lens test (a), the astigmatic axial angle of the eye to be examined is measured. In the cross cylindrical lens test (C), the astigmatism degree of the eye to be inspected is measured. In the following R/G test, it is confirmed whether or not the adjustment by the eye to be inspected is effective in the test performed. In the VA test, the maximum vision of the eye to be examined is determined.

When the result of the objective refraction for the same subject is obtained in S1, in S3, the self-refraction advancing process is set based on the result of the objective refraction (for example, the eye refractive power (at least one of sphere power, astigmatism power, and astigmatism axis angle) measured for the same subject' S eye). For example, in each test included in the advancing process, the type and size of the optotype to be displayed by the optotype display unit 16, and the optical element to be initially arranged in the inspection window of the correction optical system 11 may be set based on the result of the subjective refraction. In addition, if the degree of astigmatism obtained by the talent refraction is equal to or less than the threshold value, a progress process in which tests concerning astigmatism (for example, the cross cylindrical lens test (a) and the cross cylindrical lens test (C)) are omitted may be set. In S1, if the result of the subjective refraction is not obtained, a default progress may be set in S3.

Next, the CPU 21A determines a target presentation operation to be executed next by the subjective refraction device 1 according to the progress of the self-refraction and the progress of the self-refraction set in S3, and outputs a presentation instruction signal (driving signal) for executing the determined presentation operation to the subjective refraction device 1 (S5). Specifically, in S5 of the present embodiment, at least one of the optical element disposed in the inspection window of the correction optical system 11 and the optotype displayed in the optotype display unit 16 is determined as the next display operation. A drive signal for at least one of the drive unit 12 and the drive unit 17 for executing the determined operation is transmitted to the subjective refraction device 1. Further, when a drive signal is transmitted to subjective refraction device 1, CPU 21A outputs a guidance sound corresponding to the inspection content from speaker 33A. Thus, the subject can observe the presented examination optotype after appropriately grasping the examination content.

In the present embodiment, the drive signal is transmitted from the first information processing apparatus 2A to the drive units 12 and 17 via the relay unit 19 (see fig. 1). Thus, the signal transmitted from the first information processing apparatus 2A does not need to be via a dedicated controller or the like. Therefore, signal processing by a dedicated controller or the like can be omitted, and hence optometry can be performed more smoothly.

In self-refraction, after grasping the inspection content from the guidance sound, the subject visually recognizes the inspection optotype presented by the subjective refraction device 1, and inputs a reply after the visual recognition to the first information processing device 2A. As an example, in the present embodiment, the response is input by the subject operating the dedicated operation unit 34A adapted to input the response of subjective refraction. However, the answer may be input through a normal operation unit 34A (for example, a mouse, a touch panel, a keyboard, or the like). The answer may be input by the sound signal converted by the microphone 32A.

The CPU 21A determines whether a reply from the subject is input (S7). If a reply is input (S7: yes), the input reply and an optically specific correction value (measurement value) of the eye to be inspected are stored in the storage device 22A (S8). Based on the reply input in S7, the optotype presented in the eye to be inspected when the reply is input, and the optical characteristics of the optical element (i.e., the optical characteristics of the optotype beam) arranged in the inspection window of the corrective optical system 11, a corrective value of the optical characteristics of the eye to be inspected is acquired.

Then, if a series of self-refraction has not been completed (S9: NO), the process returns to S5, causing the self-refraction to proceed according to the boosting process. As an example, in the VA test of the present embodiment, when the answer from the subject acquired in S7 is a correct answer, the CPU 21A determines the next target presentation operation so that the target presented by the target presenting unit 16 is set to a target having a vision value one level higher than that of the target presented last time (for example, a target having a size smaller by one level). In addition, when the answer from the subject acquired in S7 is a wrong answer, the CPU 21A determines the next target presentation operation so that the target presented by the target presenting unit 16 is set to a target having a vision value lower by one level than the target presented last time (for example, a target having a size one level larger than the target). The CPU 21A may determine the correction degree or the like of the optical element disposed in the inspection window of the correction optical system 11 as the next target presentation operation simultaneously with the target switching.

Further, the processes of S7 to S9 are repeatedly executed, and if a series of self-optometries are successfully completed (S9: YES), the optometries control process is directly ended.

If no answer is input from the subject (S7: NO), it is determined whether or not the self-refraction condition satisfies a predetermined condition with a high possibility of being inappropriate (S11). As an example, in the present embodiment, when a predetermined time has elapsed without inputting a reply from the subject after the presentation instruction signal is transmitted in S5, it is determined that the predetermined condition is satisfied. In addition, when the answer input by the subject is not proper (for example, when an answer different from the candidate of the answer required for the subject is input, when the same answer is continuously input a predetermined number of times or more, or when an answer of a number of times greater than the number of times required for the subject is input), it is determined that the predetermined condition is satisfied. If it is determined that the predetermined condition is satisfied (S11: YES), a self-refraction assistance process is executed (S13).

If no answer is input from the subject (no in S7) and the condition for self-refraction is not satisfied (no in S11), the CPU 21A determines whether or not an instruction to execute the auxiliary operation for self-refraction is input from the subject (S12). As an example, in the present embodiment, the subject can input an instruction to execute the assist operation of self-refraction by operating a HELP (HELP) button provided in a dedicated controller, a HELP button displayed on the display unit 35A, or the like. If no input is made (S12: NO), the process returns to S7. If an instruction to execute the assist operation is input (S12: yes), a self-refraction assist process is executed (S13).

Details of the self-refraction assistance process will be described with reference to fig. 4. First, the CPU 21A executes inspector call processing (S21). As an example, in S21 of the present embodiment, the CPU 21A transmits an inspector call instruction to one or more second information processing apparatuses 2B that have established remote access to the first information processing apparatus 2A via the network 5 (S4). The inspector call instruction is an instruction for causing the second information processing apparatus 2B to execute a call action of the inspector to request the inspector to perform self-refraction assistance. For example, the call operation may be performed by at least one of a sound output and an image display. By performing the calling operation, the user (inspector) of the second information processing apparatus 2B can appropriately grasp the meaning of the need for self-refraction assistance (remote assistance in the present embodiment).

Next, the CPU 21A determines whether there is a response from the inspector as the user of the second information processing apparatus 2B (S22). If no response is obtained from any of the second information processing apparatuses 2B (S22: no), the self-refraction assistance cannot be performed by the inspector, and therefore the standby state is set after the determination of S22 is repeated. When a user of one of the second information processing apparatuses 2B is in a state capable of supporting self-refraction and a response instruction is input to the second information processing apparatus 2B (S22: yes), the process proceeds to S23.

Next, the CPU 21A starts transmission and reception of sound data with the second information processing apparatus 2B used by the inspector assisting the self-refraction, thereby starting the call processing (S23). As a result, the self-refraction assisting process to be described later is executed in a state where the subject and the examiner can talk. In detail, the CPU 21A transmits the sound data input through the microphone 32A to the second information processing apparatus 2B. In addition, the CPU 21A receives sound data input to the second information processing apparatus 2B via the microphone 32B, and outputs to the speaker 33A. Further, the CPU 21A may also transmit and receive image data while transmitting and receiving sound data with the second information processing apparatus 2B. In this case, the CPU 21A may also transmit the image data input through the camera 31A to the second information processing apparatus 2B. The CPU 21A may receive the image data input to the second information processing apparatus 2B via the camera 32B and display the image data on the display unit 35A.

Next, the CPU 21A causes the self-refraction assistance screen to be displayed on the display unit 35B (see fig. 3) of the second information processing apparatus 2B used by the inspector assisting the self-refraction (S24). As shown in fig. 3, the self-refraction-assisted screen of the present embodiment includes an operation image area 50 and a progress display area 51.

An operation image including information of the optical characteristics of the optotype beam presented to the eye to be inspected is displayed in the operation image area 50. In the operation image of the present embodiment, a value related to the optical characteristic of the optotype beam to be presented to the eye to be inspected is displayed for each type of optical characteristic. By operating various buttons, values, and the like on the operation image area 50 through an operation unit such as a touch panel or a mouse, the inspector can instruct values related to a desired one of a plurality of types of optical characteristics (sphere, cylinder, and astigmatic axis angles, and the like). Further, if refraction is properly performed, the correction value of the optical characteristic displayed in the operation image becomes a measured value of the optical characteristic of the eye to be inspected.

In the present embodiment, the progress display area 51 is displayed on the display section 35A connected to the first information processing apparatus 2A in addition to the display section 35B connected to the second information processing apparatus 2B. The progress display area 51 of the present embodiment is provided with a progress display field 52, an elapsed time display field 54, left and right eye display fields 55, a help button 56, and a TOP (TOP) button 57. As described above, the progress display field 52 displays the progress set in association with the self-refraction being performed. Furthermore, in the example shown in fig. 3, the process that is ongoing at this point in time in the entire advancing process (that is, the plurality of tests included in the advancing process) is displayed above the advancing process by arrow 53 and thick boxes.

The elapsed time display field 54 displays the elapsed time after the start of the self-refraction in execution. The procedure in progress at this point in time in the entire advancing process is displayed in the left-right eye display field 55 as in the case of which of the left and right eyes of the subject is subjected to. When the subject inputs an instruction to execute the self-refraction assisting operation, the subject operates the help button 56. When the screen displayed in the progress display area 51 is to be returned to the top screen of the self-refraction application, the top button 57 is operated.

In the self-refraction assistance to be described later (S24 to S43), as described above, the sound signal input from the microphone 32A to the first information processing apparatus 2A is converted into sound by the speaker 33B of the second information processing apparatus 2B. In addition, the sound signal input from the microphone 32B to the second information processing apparatus 2B is converted into sound by the speaker 33A of the first information processing apparatus 2A. Thus, the examiner and the examinee can perform a dialogue in the assistance of self-refraction. In addition, an inspector using the second information processing apparatus 2B for assisting self-refraction can input various instructions for assisting self-refraction through at least one of the operation part 34B and the microphone 32B.

Next, the CPU 21A determines whether or not it is in the process of performing manual assistance by the inspector (S26). In the present embodiment, as a method for assisting the examiner in self-refraction, either indirect assistance or manual assistance is selected. The indirect assistance is the following method: the inspector indirectly assists the self-refraction while advancing the self-refraction by the self-refraction application in accordance with the advancing process set in S3. The manual assistance is the following method: the refraction is advanced according to the instructions entered by the inspector to replace the advancement of the self-refraction according to the advancement process, thereby assisting the self-refraction.

The inspector can cause the first information processing apparatus 2A to perform any one of indirect assistance and manual assistance by using various methods. As an example, in the present embodiment, it is preset that the indirect assist is performed first at the start of the self-refraction assist process. Further, the indirect assistance is switched to the manual assistance by inputting an operation instruction, a correction instruction of a correction value, or an instruction of omitting a process to the subjective refraction device 1 by operating various buttons or the like on the image area 50. However, the switching method between the indirect assist and the manual assist can be appropriately selected. For example, a button for switching between indirect assistance and manual assistance may be provided on the self-refraction assistance screen.

If it is in the process of performing the indirect assistance (S26: NO), the CPU 21A judges whether or not a reply of the subject visually recognizing the presented optotype is inputted by the examiner or the subject (S27). In the present embodiment, in the course of performing the indirect assistance, the subject can input a reply heard from the subject to the second information processing apparatus 2B by operating the operation unit 34B connected to the second information processing apparatus 2B. The reply input to the second information processing apparatus 2B is transmitted to the second information processing apparatus 2A. Therefore, even when the subject cannot grasp the reply method or the like in self-refraction, the progress of self-refraction can be appropriately assisted. In the present embodiment, even in the process of performing the indirect assistance, the examiner can personally input a response after visually recognizing the optotype in the same manner as in S7 (see fig. 2). Therefore, even when the subject receives the advice of the examiner and grasps the reply method or the like, the subject can personally input the reply to advance the optometry process. However, in the course of performing the indirect assistance, the reply may be received by one of the first information processing apparatus 2A and the second information processing apparatus 2B.

If the answer of the subject is not input to either one of the first information processing apparatus 2A and the second information processing apparatus 2B (S27: no), the process proceeds directly to S38. When the answer of the subject is input to the first information processing apparatus 2A or the second information processing apparatus 2B (S27: yes), the input answer and the optically specific measurement value of the subject' S eye are stored in the storage device 22A (S28) in the same manner as S8 (see fig. 2). Next, the CPU 21A determines a target presentation operation to be executed next by the subjective refraction device 1 according to the progress of the progress and the progress status at the time point set in S3 (see fig. 2), and outputs a presentation instruction signal (drive signal) for executing the determined presentation operation to the subjective refraction device 1 (S29). That is, the self-refraction performed by the self-refraction application according to the boosting process is continued also later. After that, the process goes to S38.

In addition, if it is in the process of not performing indirect assist but performing manual assist (S26: yes), the CPU 21A determines whether an operation instruction for manually advancing at least a part of the advancing process by the inspector is input by the inspector (S31). The examiner can determine an operation instruction (that is, at least one of an instruction of the arrangement operation of the optical elements in the correction optical system 11 and an instruction of the presentation operation of the optotype in the optotype presenting unit 16) for the subjective refraction device 1 based on, for example, the display content of the self-refraction assistance screen (see fig. 3) or a dialogue with the examinee. In this case, the inspector inputs the determined operation instruction to the second information processing apparatus 2B via the operation unit 34B or the like. The input action instruction is acquired by the first information processing apparatus 2A via the network 5. When an operation instruction is input and acquired (yes in S31), CPU 21A transmits a presentation instruction signal (drive signal) for causing subjective refraction device 1 to execute the instructed operation to subjective refraction device 1 (S32).

Next, the CPU 21A determines whether or not a correction instruction of the correction value stored in S8 (see fig. 2) or S28 is input by self-refraction (S33). When the inspector determines that correction of the correction value (measured value) displayed on the self-refraction-assisted screen (see fig. 3) is necessary, a correction instruction of the correction value to be corrected is input to the second information processing apparatus 2B via the operation unit 34B or the like. The inputted correction instruction is acquired by the first information processing apparatus 2A via the network 5. When a correction instruction is input (S33: yes), the CPU 21A corrects the correction value according to the instruction (S34).

Next, the CPU 21A determines whether or not an omission instruction of at least a part of the progress of the pushing (at least any one of the tests in the present embodiment) is input (S35). When the instruction to omit is input via the second information processing apparatus 2B and the network 5 (S35: yes), the CPU 21A omits the instructed test from among the plurality of tests included in the progress of the progress (S36). After that, the process goes to S38.

Next, the CPU 21A determines whether or not a series of optometries performed on the subject is completed (S38). For example, the CPU 21A may determine that a series of optometries is completed when the self-optometries performed according to the advancing process are completed. Further, the CPU 21A may determine that a series of optometries is completed when an instruction to end the optometries of the subjects is input. When the series of optometries is completed (S38: yes), the process ends.

Next, the CPU 21A determines whether or not a continuation restart instruction of the self-refraction is input (S39). The resume start instruction is an instruction as follows: the refraction is restarted from the next process of the progress process set in S3 (refer to fig. 2) in which the refraction has been completed. For example, the CPU 21A may determine that a resume instruction is input when a resume button (not shown) or the like is operated by the subject. When a continue restart instruction is input via the second information processing apparatus 2B and the network 5 (S39: yes), the CPU 21A sets a restart process for restarting the self-refraction as the next process of the progress process in which the refraction process has been completed (S40), and returns the process to the optometry control process (refer to fig. 2). In the subsequent processing of S5 to S9, the self-refraction is restarted from the restart process set in S40. If no instruction to resume is input (no in S39), the process proceeds directly to S42.

Next, the CPU 21A determines whether or not a designation restart instruction for self-refraction is input (S42). The designation restart instruction is an instruction as follows: the self-refraction is restarted from the procedure designated by the inspector during the advancing procedure set in S3 (refer to fig. 2). In the present embodiment, the examiner can input a designation restart instruction by designating a restart process for restarting the self-refraction on the progress displayed in the progress display field 52 (see fig. 3) of the self-refraction assistance screen. As an example, in the present embodiment, the inspector uses a mouse, a touch panel, or the like to input a command for designating restart. Further, a restart instruction button (reset button) may be provided in the self-refraction auxiliary screen or the like to delete the result of the self-refraction already performed in accordance with the progress of the self-refraction, and to restart the designation of the self-refraction from the initial start of the progress of the self-refraction. When a designation restart instruction is input via the second information processing apparatus 2 and the network 5 (S42: yes), the CPU 21A sets the restart process for restarting the self-refraction as a process designated by the designation restart instruction during the progress (S43), and returns the process to the optometry control process (see fig. 2). In the subsequent processing of S5 to S9, the self-refraction is restarted from the restart process set in S43.

The technology disclosed in the above embodiment is merely an example. Thus, the technique exemplified in the above embodiment can also be modified. For example, only a part of the techniques exemplified in the above embodiments may be executed. As an example, in the subjective refraction system 100 according to the above embodiment, when a problem occurs in self-refraction (S11: "yes", or S12: "yes"), the examiner call process (S21) and the examiner support process (S23 to S43) are performed together. However, subjective refraction system 100 may execute only one of the inspector call process and the inspector auxiliary process. For example, even if the inspector is called only by the inspector call process, self-refraction can be appropriately assisted.

In the above embodiment, the self-refraction is started in a state where the second information processing apparatus 2B is connected to the first information processing apparatus 2A. However, after a problem occurs in the progress of self-refraction (S11: yes, or S12: yes), the second information processing apparatus 2B may be connected to the first information processing apparatus 2A.

The self-refraction assistance process of the present embodiment is executed in accordance with an instruction input to the second information processing apparatus 2B disposed at a remote place (refer to fig. 4). However, the self-refraction assistance process may be performed in accordance with an instruction directly input to the first information processing apparatus 2A (for example, an instruction input to the first information processing apparatus 2A by the inspector operating the operation portion 34A, or the like). That is, an inspector at a place where the subjective refraction device 1 is installed may input an instruction for assisting self-refraction. Further, the first information processing apparatus 2A and the second information processing apparatus 2B may receive input of an instruction for assisting self-refraction. In this case, the examiner can assist the self-refraction regardless of whether the examiner is located at the location where the subjective refraction device 1 is provided or at a distance. When an instruction for supporting self-refraction is input via the first information processing apparatus 2A, the processing of the call inspector in S21 (see fig. 4) may be performed by the first information processing apparatus 2A or by both the first information processing apparatus 2A and the second information processing apparatus 2B.

In S5 in fig. 2 and S29 in fig. 4, the process of outputting the presentation instruction signal to subjective refraction device 1 based on the advancing process is an example of the "self-refraction advancing step". The process of acquiring a reply from the subject in S7 of fig. 2 and S27 of fig. 4 is an example of the "reply acquisition step". The process of storing correction values in S8 of fig. 2 and S28 of fig. 4 is an example of the "correction value storing step". The self-refraction assistance process shown in fig. 4 is an example of the "self-refraction assistance step". The process of outputting the presentation instruction signal in response to the operation instruction in S31 and S32 of fig. 4 is an example of the "manual advance step". The correction value correction process in S33 and S34 in fig. 4 is an example of the "correction value correction step". The process of omitting the advance process in S35 and S36 of fig. 4 is an example of "process omitting step". The process of acquiring the response of the subject in accordance with the instruction input by the examiner in S27 of fig. 4 is an example of the "proxy response acquisition step". The process of restarting the self-refraction from the next process in S39 and S40 in fig. 4 is an example of "continuing to restart the process". In S42 and S43 in fig. 4, the process of self-optometrizing and restarting from the process designated by the inspector is an example of "designating and restarting step". The process of restarting self-refraction in S33 and S34 in fig. 4 is an example of "self-refraction restarting step". The process of displaying the progress procedure in S24 of fig. 4 is an example of the "procedure display step".
