Method of molding ophthalmic lens product, and mold assembly used in the method

摘要

A method of molding an ophthalmic lens product by using a mold assembly which has a mold cavity, the lens product having a configuration corresponding to that of an ophthalmic lens or a precursor of the ophthalmic lens and being obtained by polymerizing a liquid monomer composition in the mold cavity to provide a polymer product which gives the lens product, the method comprising the steps of: preparing the mold assembly having a monomer storage space for storing the liquid monomer composition, which storage space is held in fluid communication with the mold cavity; filling the mold cavity of the mold assembly with the liquid monomer composition while the liquid monomer composition is accommodated in the monomer storage space; and polymerizing the liquid monomer composition at a temperature of 10-80° C. while a pressure higher than the atmospheric pressure is applied directly to a liquid surface of a mass of the liquid monomer composition accommodated in the monomer storage space.
