The correspondence between the index and the name of the test is stored as a default and is usually displayed based on this default, but the display can be switched according to the situation.

This will be described with reference to the example shown in FIG.
In FIG. 4, among several registered optometry programs (courses), a course called “a subjective optometry course 1” is executed, and the eyesight value test, which is the fourth examination, is completed.
This indicates that the second binocular balance test is being performed.

The optometry result display column 131-2 shows the progress of the test at the stage when the red-green test, which is the second test, is completed (when the feed switch 45 is pressed).

Similarly, the optometry result display section 131-3 shows the progress of the examination at the stage where the third examination, that is, the cross cylinder test is completed, and the optometry result display section 131-4 shows the progress of the examination.
This shows the progress of the test at the stage when the visual acuity value test as the second test is completed.

Since the binocular balance test is currently being executed and the addition test is performed after the binocular balance test is completed, the optometry result display columns 131-5 and 131-6 are blank.

The fourth and earlier optometry result display columns 131-2, 131-3, and 131-4 are displayed with a white background, so that the examiner can check the progress of the examination and the progress of each stage. You can know.
