OPTOMETRY SYSTEM

PURPOSE:To improve the workability of the program optometry, by deciding the relation of the position of display scope of a specific optometry data, and the position of the operation index linking to the movement of an operating means, when the operating means is moved by some cause in an eye examination, and displaying the result. CONSTITUTION:An optometry data of an eye to be examined is displayed on the screen of a display means 26 together with the operation index linking to the operation of an operating means 29, and the optometry of the eye to be examined is carried out while setting the optometry data of a display scope specified by the operation index depending on the operation data from the operating means 29. In such an optometry device 1, the relation between the position of the display scope of the optometry data specified by the operation index and the position of the operation index linking to the operation of the operating means 29 is decided by a control device, and when it is decided that the operation index is within the display scope of the optometry data, the operation index is restored to a specific position in the display scope of the optometry data depending on the operation of the operating means 29, by an operation index display control means attached to the control device.
