(Optometry information analysis processing)
An analysis process of the optometry information 18a for the eye accommodation function will be described.
(Process to convert to a single axis bar graph)
First, a process for converting the optometry information 18a of the eye accommodation function into a uniaxial bar graph 61 will be described.
FIG. 3 is a diagram illustrating a form in which the optometry information 18a of the eye accommodation function according to the embodiment is converted into a bar graph 61.
FIG. 3A is a graph showing the measurement result of the eye accommodation function measured by the objective optometry apparatus 10 as a bar graph 60.
FIG. 3B is a diagram in which the biaxial bar graph 60 of FIG. 3A is converted into a uniaxial bar graph 61.
The optometry information 18a for the eye accommodation function is provided for both the left and right eyes. Here, only one eye will be briefly described. The optometry information 18a is information on the state of the naked eye.

An outline of the display method of the bar graph 60 in FIG.
The display method of the bar graph 60 is the same as that shown in FIGS.
The bar graph 60 is a biaxial graph.
The horizontal axis of the bar graph 60 indicates the distance from the far point position D0 (= 0D) to the visual target.
The far point is a position where the refractive power of the eye to be examined does not change due to the movement of the target and is not adjusted. That is, the far point is the farthest position where the eye to be examined can be clearly seen. The far point position is an arrangement position where the eye to be examined looks as if the visual target is arranged at the far point. Therefore, the bar graph 60 has a different far point position depending on the eye to be examined, and reflects the spherical power corrected by the glasses or the like.
The unit of the horizontal axis of the bar graph 60 is normally D (diopter). In FIG. 3A, D (diopter) is converted to meter (m), and D (diopter) and meter (m) are shown together.
The vertical axis of the bar graph 60 indicates the eye refractive power at each target position. The unit is D (diopter).

The number of measurements at each target position is five, and the five measurements are set as one set. The measurement range is 0-3D. The moving distance of the target is 0.5D intervals. For this reason, a total of 7 sets (total 35 times) are performed at 7 locations.
Note that the number of measurements (5 times), moving distance (0.5D), measurement range (0 to -3D), and the like of each target position can be changed as appropriate.

Each measurement result is displayed by a bar graph 60. The inside of the bar of the bar graph 60 is hatched according to the appearance frequency of the high frequency component indicating ciliary tonic tremor. For this reason, the degree of tension of each eye to be examined can be visually recognized.
A bar graph 60 in FIG. 3A shows the following three levels of tension of the eye to be examined by three types of hatching.
Relaxed state: appearance frequency of high frequency component 0 to 50 db
・ Slight strain state (Less strain): Appearance frequency of high frequency component 50 to 70 db
-Tension state (More strain): Appearance frequency of high frequency component 70-100 db
In addition, the number of stages of the degree of tension can be changed as appropriate.
Moreover, the tension degree should just be discriminate | determined visually, The expression is not limited to hatching, For example, you may combine either color, a density | concentration, a brightness | luminance, etc., or these.

The process of converting the bar graph 60 in FIG. 3A into the uniaxial bar graph 61 in FIG. 3B is performed by the control unit 59 of the subjective optometry apparatus 50 in the following procedure.
(1) The degree of tension at one location of the target position is converted into one type.
The optometry information 18a at one location has measurement information of five tension tremors. The control unit 59 averages these and converts the degree of tension into one type. The control unit 59 selects hatching corresponding to the degree of tension after conversion from the above three types.
The control unit 59 performs this process at all seven locations.
(2) The control unit 59 deletes the eye refractive power information from the optometry information 18a. Thereby, the information on the vertical axis is deleted from the information of FIG.
(3) As shown in FIG. 3B, the control unit 59 finally displays the bar 62 on the horizontal axis. The horizontal axis indicates the distance from the far point position D0 (= 0D) to the target as in FIG. And the control part 59 displays the inside of a stick | rod by the hatching of said (1). As will be described later, the control unit 59 displays the bar graph 61 on the display unit 51b.
A bar is a concept including a line. Even in the case of a line, a difference in the degree of tension can be expressed by a difference in color or the like.

  Thus, the optometry system 1 converts the bar graph 60 of FIG. 3A having a plurality of information into the bar graph 62 of FIG. 3B. Thereby, the optometry system 1 can display the eye adjustment function according to the viewing distance from the eye to be examined in an easy-to-understand manner. For this reason, even a subject who does not have specialized knowledge about medical care can easily understand the relationship between viewing distance and degree of tension.

(Analysis process according to the examiner's operation)
Next, analysis processing performed by the subjective optometry apparatus 50 according to the operation of the subjective optometry apparatus 50 by the examiner will be described.
FIG. 4 is a flowchart illustrating the analysis processing according to the embodiment.
5 to 6 are diagrams illustrating display on the display unit 51b in the analysis processing of the embodiment.

The analysis process assumes the following conditions.
The measurement of both eyes is completed with the objective optometry apparatus 10.
The binocular optometry information 18a has been moved from the subjective optometry apparatus 50 to the storage unit 58 of the objective optometry apparatus 10.
In the following example, in order to simplify the description, an example in which the optometry information 18a for both eyes is the same will be described.

In S1, when the examiner performs an operation for displaying the optometry information 18a in a graph, the control unit 59 accepts this operation and proceeds to S2.
In S <b> 2, as shown in FIG. 5A, the control unit 59 performs a process of converting the binocular optometry information 18 a stored in the storage unit 58 into the uniaxial bar graph. The control unit 59 creates bars 71R and 71L corresponding to the left eye and the right eye, and creates a bar graph 71. The bar graph 71 is an arrangement of bars 71R and 71L. The control unit 59 displays the bar graph 71 on the display unit 51 b of the desktop operation device 51.
In addition, the control part 59 displays what converted the visual distance from the eye to be examined into a meter (m) so that a subject etc. can understand easily.
Further, as described above, the bar graph 71 reflects the spherical power S or the equivalent spherical power S + C / 2 corrected with glasses or the like.

Here, the optometry information 18a may include a degree of addition (ADD) as a correction value. The examiner can display a bar graph reflecting this addition degree by operating the operation unit 51a.
In S10, when it is determined that the operation for reflecting the addition degree is accepted (S10: YES), the control unit 59 proceeds to S11, whereas when it is determined that the operation is not accepted (S10: NO). , Go to S20.
In S11, as shown in FIG. 5B, the control unit 59 creates the bars 72R and 72L reflecting the addition (ADD) corrected by the glasses or the like for the bars 71R and 71L. Create FIG. 5B is an example reflecting the addition +1.00. Then, the control unit 59 displays the bar graph 71 side by side on the upper side and the bar graph 72 on the lower side.
As a result, the optometry system 1 can clearly display the degree of eye fatigue in near vision and distance vision when the glasses for both distance and near vision are prescribed, and can display the effect of the addition in a visible manner. In addition, the optometry system 1 can display, for example, whether or not the relaxed state is continuous between distance and near use so as to be visible.
The bar graph moves to the left when the spherical power S and the addition ADD are added to minus (−), and moves to the right when added to plus (+). Furthermore, since the distance (m) is represented by the reciprocal number of the diopter (D), the bar graph becomes shorter as it approaches the eye to be examined. In this case, the direction farther from the far point ∞ (left side) and the subject side (right side) than 0.2 m are cut.

Here, the examiner can confirm the manner in which the bar graph changes according to the change in the addition power by operating the operation unit 51a.
In S20, when it is determined that the addition change operation has been accepted (S20: YES), the control unit 59 proceeds to S21. On the other hand, when it is determined that the addition is not accepted (S20: NO), the control unit 59 proceeds to S30. move on.
In S21, as shown in FIG. 6A, the control unit 59 creates bars 73R and 73L reflecting the addition ADD + 1, 00 for the bars 71R and 71L, and creates a bar graph 73. FIG. 6B shows an example in which the addition is changed from +1.00 to +0.50. The control unit 59 creates bars 74R and 74L reflecting the added power ADD after changing the bar graph 71 on the upper side and the bar graph 74 on the lower side, and displays them side by side.
In FIG. 6B, the addition is weaker than in FIG. 6A. For this reason, for example, the distance for near vision changes from 0.25 m (FIG. 6A) to 0.28 m (FIG. 6B).

Here, the examiner can select whether to end the analysis by operating the operation unit 51a.
In S50, if the control unit 59 determines that an operation to end the analysis has been received (S50: YES), the control unit 59 proceeds to S60. On the other hand, if it is determined that the operation has not been received (S50: NO), the control unit 59 starts from S10. Repeat the process.

By the process repeated from S10, the examiner can repeatedly deform the bar graph. Thereby, it is hard to get tired for the eye to be examined, and an appropriate correction value for the near vision distance at the time of use can be obtained. The examiner can reflect the correction value thus obtained in the optometry using the optometry optical system of the subjective measurement unit 52.
In S60, the control unit 59 ends the series of processes.

In addition to the above, the subjective optometry apparatus 50 can perform, for example, the following naked eye graph display processing and lens meter display processing.
FIG. 7 is a diagram illustrating the display of the display unit 51b in the naked eye graph display process of the embodiment.
FIG. 8 is a diagram illustrating a display on the display unit 51b in the lens meter display process of the embodiment.
FIG. 9 is a diagram illustrating a display on the display unit 51b in the spherical power or equivalent spherical power adjustment process of the embodiment.
(Naked eye graph display processing)
From the state in which the bar graph 81 (bars 81R, 81L) of FIG. 7A reflecting the spherical power S or the equivalent spherical power S + C / 2 is displayed, the control unit 59 performs the spherical power S according to the operation of the operation unit 51a. Alternatively, the bar graph 82 (bars 82R and 82L) of FIG. 7B in which the prescription value of the equivalent spherical power S + C / 2 is changed is created and displayed. The bars 81R and 81L are created by the objective optometry apparatus 10 based on the measurement information, similarly to the bars 71R and 71L.
Thereby, the subjective optometry apparatus 50 can display the tension state before and after correction of the spherical power S or the equivalent spherical power S + C / 2 in an easy-to-understand manner.
That is, the subjective optometry apparatus 50 has a tension state in which the prescription for hyperopia is prescribed (the upper diagram in FIG. 7A or FIG. 7B) and a tension state in which the prescription is not prescribed (FIG. 7B). (Below) can be displayed.

(Lens meter display processing)
The control unit 59 displays lens information such as glasses worn by the subject on the graph 83 (bars 83R and 83L) in FIG. 8A reflecting the spherical power S or the equivalent spherical power S + C / 2. The reflected bar graph 84 (bars 84R and 84L) shown in FIG. 8B is created and displayed. The lens information may be acquired by a lens meter and copied to the subjective optometry apparatus 50 using a storage medium such as a USB memory, a communication cable, or the like.
In addition, the graph display of the tension degree of FIG. 8 was simplified to two steps. Further, the bars 83R and 83L are created in the objective optometry apparatus 10 based on the measurement information, similarly to the bars 71R and 71L.
Thereby, the subjective optometry apparatus 50 can display the tension state before and after wearing such as the glasses worn by the subject in an easy-to-understand manner.

(Spherical power adjustment process)
As shown in FIG. 9A, the control unit 59 displays a bar graph 84 (bars 84R and 84L) reflecting the spherical power S or the equivalent spherical power S + C / 2 in accordance with the operation of the operation unit 51a. Then, an adjustment input of spherical power S or equivalent spherical power S + C / 2 is received. FIG. 9B shows a scene in which the spherical power S or the equivalent spherical power S + C / 2 is changed from −1.50 to −1.00. The control unit 59 creates and displays a bar graph 85 (bars 85R and 85L) reflecting the adjustment of the spherical power S or the equivalent spherical power S + C / 2 on the bar graph 84.
In addition, the graph display of the tension degree of FIG. 9 was simplified to two steps. The bars 84R and 84L are created by the objective optometry apparatus 10 based on the measurement information, similarly to the bars 71R and 71L.
Thereby, the subjective optometry apparatus 50 can display the tension state before and after the adjustment of the spherical power S or the equivalent spherical power S + C / 2 in an easy-to-understand manner. By referring to the bar graph 85 in FIG. 9 (B), the examiner and the like can use the glasses produced based on this information for near vision as long as they are not used for distance vision of 2 m or longer. It can be analyzed that it can be used. As a result, it is possible to determine whether or not to produce spectacles or the like for both distance and perspective having addition power, or to prepare spectacles or the like adjusted only for spherical power S or equivalent spherical power S + C / 2. .

  7 to 9 can be incorporated in the flowchart shown in FIG. 4 in the same manner as the addition degree changing process (S20, S21) and the like. Accordingly, the examiner or the like can repeatedly deform the bar graph in various ways to obtain an appropriate correction value for the eye to be examined.

  As described above, the subjective optometry apparatus 50 of the embodiment displays the optometry information 18a having the degree of appearance frequency of the high frequency component indicating ciliary tonic tremor in a graph, and is effective for the subjective optometry. Available. In addition, the ease of fatigue of the subject's eye can be displayed in an easy-to-understand manner, and can be easily explained to the subject at the medical site.
