Abstract: PURPOSE:To obtain the contact lens which has an excellent visual correcting effect and oxygen permeability to allow long-period wearing as well as excellent shape stability, staining resistance and durability by incorporating a copolymer contg. a specific unsatd. dicarboxylate monomer as an essential raw material monomer into the lens. CONSTITUTION:The copolymer contg. 2 to 95wt.% unsatd. dicarboxylate monomer expressed by formula I as the essential raw material monomer is incorporated into the lens. In the formula I, R1, R2 denote a hydrogen atom, 1 to 12C alkyl group, 1 to 12C alkenyl group, 3 to 12C cyclic alkyl group, etc.; X to Z denote a methyl group, the compd. expressed by formula II, etc.; m denotes 0 or 1; n denotes 0 to 3 integer; l denotes 2 to 4 integer. The oxygen permeability is enhanced in this way and the deposition of protein, lipid and inorg. matter, etc., on the surface is prevented in this way.
