  In FIG. 5, as an example, as a guide for guiding the updating operation of the parameter of the optical property data corresponding to the visual target chart 3a-1 for the red green test, the addition power is raised by one unit by left click of the mouse 6b corresponding to red. And the right click of the mouse 6b corresponding to the green indicates that the addition power is lowered by one unit.

  The optical characteristic data display area 3a-2 displays optical characteristic data corresponding to refractive power which is an optical characteristic such as spherical power, astigmatic power and axial angle of a lens as an optical element set in the optometry windows 11a and 11a. Area.

  In the optical characteristic data display area 3a-2, here, respective items of spherical dioptric power, astigmatic dioptric power, axial angle and addition dioptric power among the refractive power of the lens are displayed, and the right eye and the left eye of the subject 2 The numerical values of the optical characteristic data currently set in the optometry windows 11a and 11a are displayed corresponding to each item.

  The arithmetic control circuit unit 15 controls the correction device 4 such that an optical element having an optical characteristic corresponding to the optical characteristic data displayed in the optical characteristic data display area 3a-2 is set in the eye examination windows 11a and 11a. It is

  The subjective inspection is performed using a lens having an optical characteristic corresponding to the optical characteristic data displayed in the optical characteristic data display area 3a-2.

  The guide display area 3a-3 is an area for displaying a guide for guiding the update operation of the parameter of the optical property data displayed in the optical property data display area 3a-2, and It is an area provided for convenience. The guide display area 3a-3 may be displayed only when the "self-awareness inspection mode" for performing a subjective inspection by the subject himself / herself is selected from the controller device 5, and a usual subjective inspection When the “normally aware inspection mode” for performing the above is selected from the controller device 5, it is not necessary to display.

  The arithmetic control circuit unit 15 follows the guide of the guide display area 3 a-3 according to the parameter change instruction of the optical property data inputted through the operation main body 6 by the subject 2 himself, the optical property data display area 3 a − It also has a function of executing control to update the optical characteristic data displayed on the second and the like.

  The storage unit 16 can store optical characteristic data before update and optical characteristic data after update.

  For example, when the mouse 6b is right-clicked by the subject 2 or the like, the arithmetic control circuit unit 15 increments the parameter of the “spherical surface” power, which is one of the optical characteristic data, by one unit. Alternatively, when the mouse 6b is left-clicked by the subject 2 or the like, the arithmetic control circuit unit 15 decrements the parameter of the “spherical surface” power, which is one of the optical characteristic data, by one unit.

  When the subject 2 can not visually recognize the guide display area 3 a-3, the screen is switched to a voice guidance mode in which the content of the guide display area 3 a-3 is guided by voice by rotation of the scroll wheel of the mouse 6 b. When the change to the voice guidance mode is instructed by the rotation of the scroll wheel of the mouse 6b, the arithmetic control circuit unit 15 outputs a voice corresponding to the content displayed in the guide display area 3a-3 by the speaker 18 Do. For example, in the case of the red-green inspection, an audio of “Please right click if green is better, left click if red is better” is output. The subject operates the mouse 6b based on the voice. In order to avoid complexity, the content of the voice guidance may be kept to a minimum, such as the operation content of the guide display area 3a-3.

  The parameters may be changed according to the rotation direction and the rotation amount of the scroll wheel of the mouse 6b. For example, the parameter may be incremented according to the amount of upward rotation, or may be decremented according to the amount of downward rotation.

  Here, the arithmetic control circuit unit 15 may check whether or not the changed optical characteristic data is the content intended by the subject 2 by the content of the utterance to the microphone 6c. For example, when the arithmetic control circuit unit 15 recognizes that the voice input of "Yes" has been input to the microphone 6c, it determines parameter updating and recognizes that the voice input of "No" is input to the microphone 6c. Cancel the update As described above, the subject 2 verbally responds to the parameter update contents, and the parameter update is determined according to the contents, thereby significantly reducing the utterance of an error in the parameter update instruction of the subject 2 himself. Switching of the input between the microphone 6c and the mouse 6b may be performed by a scroll wheel.

  Next, the arithmetic control circuit unit 15 controls the visual target presentation device 3 so that the updated optical characteristic data is displayed in the optical characteristic data display area 3a-2.

  Further, the arithmetic control circuit unit 15 retracts the optical element corresponding to the optical characteristic data which has been displayed so far on the visual target presentation device 3 from the optometry windows 11a and 11a, and newly adds an optical characteristic data display area 3a-. The exchange control is executed so that the optical elements corresponding to the optical characteristic data displayed in 2 are set in the optometry windows 11a and 11a.

  The above process is summarized as shown in FIG. FIG. 6 shows the flow of processing by the arithmetic control circuit unit 15. A program for causing the operation control circuit unit 15 (processor such as a CPU) to execute this process is stored in a non-transitory tangible medium such as the storage unit 16 (ROM). This process can be repeated according to an arbitrary instruction of the subject.

  In S1, the arithmetic control circuit unit 15 receives a selection operation of a desired visual target from the list display area 20 of the display screen 12a of the monitor unit 12 via the mouse 6b.

  In S2, the arithmetic control circuit unit 15 causes the visual target chart 3a-1 selected via the mouse 6b to be displayed on the display screen 3a of the visual target presenting device 3. Further, the arithmetic control circuit unit 15 displays a guide for guiding an update operation of the parameter of the optical characteristic data corresponding to the visual target chart 3a-1.

  In S3, the arithmetic control circuit unit 15 displays the optical characteristic displayed in the optical characteristic data display area 3a-2 or the like according to the parameter change instruction of the optical characteristic data input from the subject or the like through the operation main body unit 6. Update data Further, the arithmetic control circuit unit 15 retracts the optical element corresponding to the optical characteristic data which has been displayed so far on the visual target presentation device 3 from the optometry windows 11a and 11a, and newly adds an optical characteristic data display area 3a-2. The exchange control is executed so that the optical element corresponding to the optical characteristic data displayed on the screen is set in the optometry windows 11a and 11a.

  7 to 9 are display examples of guides for guiding operations of updating parameters of various optical characteristic data.

  As described above, the optical characteristic data display area 3a-2 is displayed on the display screen 3a of the visual target presenting device 3 together with the visual target chart 3a-1. The subject 2 himself refers to the guide for guiding the updating operation of the parameters of the optical property data displayed in the optical property data display area 3a-2 of the display screen 3a, and various settings are made in the optometry windows 11a and 11a. It is possible to perform an operation of updating the parameters of various optical characteristic data. For this reason, the examinee 2 may operate the mouse 6b to update the parameters of the optical characteristic data without looking away from the visual target chart 3a-1 while looking through the optometry windows 11a and 11a. it can. This makes it possible to perform a self-awareness test.
