Manufacturing equipment of manufacturing methods and ophthalmic lens of the eye lens

摘要

PROBLEM TO BE SOLVED: To provide a new ophthalmic lens manufacturing method which can mold a target ophthalmic lens in good shape accuracy.;SOLUTION: A male mold 16 for molding a lens rear face and a female mold 14 for molding a lens front face are arranged one on top the other, and a molding cavity 18 is formed between the opposed surfaces of the male mold 16 and the female mold 14. When the ophthalmic lens is molded by packing a polymerizable monomer 40 in the molding cavity 18 and polymerizing it, the polymerizable monomer 40 in the central part of the molding cavity 18 is polymerized earlier than the monomer 40 in the peripheral part of the molding cavity 18.;COPYRIGHT: (C)2011,JPO&INPIT
