TREATMENT OF CONTACT LENS WITH SUPERCRITICAL FLUID

摘要

PROBLEM TO BE SOLVED: To provide a method for treating a lens capable of improving the optical transparency of the lens without adversely affecting the wetting property or other physical properties of the lens and to provide a lens treatment capable of improving the hydrophilicity of a lens, thereby eliminating or at least reducing the necessity of an additive or an aftertreatment. SOLUTION: A method for producing an optically transparent contact lens is provided which includes a step for molding the lens from a monomer mixture and includes a step for treating the molded contact lens with a supercritical fluid as an improvement.
