Abstract
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.
