摘要： The present invention provides an ocular lens which achieves both of oxygen permeability and surface hydrophilicity, and on which the deposition of lipids is suppressed. The ocular lens of the present invention includes a polymer material obtained by polymerizing a polymerizable composition containing, as monomer components, a siloxane monomer having a siloxane bond, and a siloxane-free crosslinkable monomer free of any siloxane bond, wherein the siloxane-free crosslinkable monomer includes an alkylene glycol chain-containing crosslinkable monomer having: a chain moiety containing 6 or more alkylene glycol repeating units; and polymerizable groups arranged at both terminals of the chain moiety.

摘要： A silicone-containing polymer material containing an internal wetting agent and being excellent in transparency, the silicone-containing polymer material being improved in antifouling property against lipids. The polymer material of the present invention is a polymer material, which is obtained by polymerizing a polymerizable mixture containing monomer components (a) and a hydrophilic polymer component (b), wherein the monomer components (a) include a silicone-containing monomer (a-1) having a siloxane bond and being free of any hydroxyl group, and a compatibilizing monomer (a-2) having a hydrogen bonding proton-containing group and being free of any silicon atom, and wherein the compatibilizing monomer has four or more carbon atoms, excluding carbon atoms contained in a polymerizable functional group, and has a solubility of less than 0.03 g/mL in water at 25° C.
