Method of manufacturing eyeglass lens
Abstract:
An aspect of the present invention relates to a method of manufacturing an eyeglass lens, which comprises a step of conducting polishing processing of a non-optical surface of a semifinished lens, one surface of which is an optical surface and the other surface of which is the non-optical surface, to create an optical surface. The semifinished lens comprises an acrylic coating on an optical surface of a lens substrate, a surface of the acrylic coating having a contact angle relative to water of equal to or less than 90°, prior to the polishing processing, a protective film is adhered through an adhesive layer of the film to the surface of the acrylic coating, and the polishing processing is conducted by polishing a non-optical surface of the lens substrate in a state where the protective film surface is secured in a block jig.
