Synthetic resin ophthalmic lens having a surface hard coat

摘要

An improved synthetic resin opthalmic lens and a method for treating the surface of the lens are provided. The lens is formed by polymerizing at least one bis(allyloxycarbonyloxy-alkoxy) dihalide-phenyl alkane and one bifunctional allyl compound, optionally with a bis(allylcarbonate) compound. The lens is chemically treated with an aqueous solution of polyethyleneglycol and an alkali metal hydroxide and a surface hard coat is formed on the treated surface.
