Kind Code:
B2
Abstract:
A method for manufacturing a contact lens having a multilayer structure using a mold, includes: (a) charging a first polymerizing composition into a space formed by combining a first mold with a second mold, and polymerizing a first semi product having a thinner thickness and a smaller outer diameter than those of a contact lens immediately before being removed from the molds after all polymerizing processes; (b) opening the first and second molds; and (c) charging a second polymerizing composition into a space formed by combining a third mold with one of the first and second mold, the first semi product fixed onto the one of the first and second molds, and polymerizing the second polymerizing composition.
