PURPOSE:To prevent the degradation in optical transparency, high oxygen permeability, bydrophilicity and resilience by constituting the insert of a copolymer essentially consisting of methacrylate and/or acrylate, organo-siloxane monomer and fluorine-contg. (meth)acrylate. CONSTITUTION:The insert is formed of the copolymer essentially consisting of the methacrylate and/or acrylate, the organo-siloxane monomer expressed by general formulas (1) and (2) and the fluorine-contg. (meth)acrylate. |
