PROCESS FOR MANUFACTURING SPECTACLE LENS, AND SPECTACLE LENS

摘要

Even when the optical surfaces (2a,2b) of spectacle lens (1) consist of machined faces, any machining traces thereon can be erased to such an extent that finding of machining traces by visual checking can be avoided at the stage of inspection. The process includes the steps of coating the optical surfaces (2a,2b) of spectacle lens (1), the optical surfaces (2a,2b) consisting of machined faces, with a coating film solution containing a material identical with the base material of the lens; and heating the coating film solution applied to the optical surfaces (2a,2b) so as to harden the same, thereby forming coating film (4). Furthermore, the process includes the step of laminating the coating film (4) with hard coating film (5) and further with antireflection coating film (6).
