The present invention is directed to a program for optometry, which is used for a control device. The program includes a first unit to measure an amount of heterophoria of eyes of an examinee to be examined in a horizontal heterophoria examination, a second unit to display an operating method to allow the examinee to implement a Sheard criterion identifying examination on a display device, a third unit to allow the examinee to implement a convergent or divergent test of the eyes based on the operating method, and a fourth unit to calculate a prism amount for prescriptions based on the heterophoria amount and the convergence or divergence of the eyes.

Program for optometry, recording medium and subjective optometric apparatus having the optometric program, and optometric method

The present invention provides an apparatus for displaying lens contour, an apparatus for processing lens contour data, and apparatus for grinding edge of eyeglass lens with the same so that these apparatuses can grasp contours of the eyeglass frame and the eyeglass lens related to three dimensional virtual display (3D V-shaped simulation), and a V-shaped figure formed in an edge surface of lens in three dimensions to represent visually assembling of the virtual frame. These apparatuses comprises, an input means of lens rim contour data for inputting left/right lens rim contour data of an eyeglass frame MF in three dimensions; a calculating/determining circuit for calculating, based on the inputted lens rim contour data, an angle of inclination of lens rim contour of either left or right eye of the eyeglass frame to lens rim of the other eye; and a liquid crystal display panel for displaying a type of inclination of left/right lens rims of the eyeglass frame, based on the calculated results, as side view from upper or lower side of the eyeglass frame.
