Abstract
An apparatus for simulating the processing of eyeglass lenses where an operation control means displays a chamfering contour of an end portion of the edge of the eyeglass lens on a display means, and the operation control means is set to be capable of specifying a chamfering location of the chamfering contour. The apparatus can be utilized in connection with an eyeglass frame selecting system in which the eyeglass lens picture can be synthesized with the eyeglass frame image and the customer's facial image so that the effect for the eyeglass lens based on the lens prescription value of the customer can be known, is provided. The eyeglass frame selecting system comprises a keyboardfor inputting the prescription value data of an eyeglass lens and a lens mold contour data based on the refraction property of a customer's objective eye, and an operation control circuitfor synthesizing the eyeglass lens image based on the prescription value of the lens inputted by the keyboardand a facial imagewith the eyeglass frame image L through a picture synthesizing circuitto display the synthesized image on a display device
