METHOD FOR PROVIDING LENS BLANKS

摘要

A method provides a machineable silicon-containing lens blank by removal of diluent from the lens blank. The method involves casting a lens blank in a mold, wherein the lens blank is made of a polymerization product of a monomeric mixture comprising a silicone-containing monomer and an organic diluent; removing the lens blank from the mold; and removing organic diluent from the lens blank.
