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.
