METHOD FOR MANUFACTURING PLASTIC LENS, GASKET FOR MOLDING PLASTIC LENS, MOLD FOR MOLDING PLASTIC LENS, JIG FOR INJECTING PLASTIC LENS RAW MATERIAL LIQUID, TOOL FOR HOLDING MOLD FOR PLASTIC LENS, AND APPARATUS FOR MANUFACTURING PLASTIC LENS

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a plastic lens capable of molding a plastic lens with decreased air bubbles and optical defects from a plastic lens raw material liquid with a high viscosity and a rapid initial polymerization speed, a gasket for molding the plastic lens suitable for using to the method, a mold for molding, a jig for injecting the plastic lens raw material liquid, a tool for holding the mold, and an apparatus for manufacturing the plastic lens.;SOLUTION: The method for manufacturing the plastic lens comprises the mixture of a plurality of polymerizable components, injection of the mixed liquid into the mold immediately after mixing, and its polymerization to obtain a molded body. The method for manufacturing the plastic lens comprises the injection of the plastic lens stock liquid flowing out from an opening of the jig for injecting into the mold for molding and curing the stock liquid to obtain the molded body. The method for manufacturing the plastic lens comprises the injection of the plastic lens stock liquid into the mold for molding held by the holding tool and curing the stock liquid to obtain the molded body.;COPYRIGHT: (C)2007,JPO&INPIT
