(57) [Summary] [Purpose] The water wettability (hydrophilicity) of the lens was improved without affecting the characteristics of the lens, and its durability was also improved, and it was also excellent in lipid stain resistance. (EN) Provided are a method for treating a surface of a hydrous contact lens, which exhibits characteristics, and a hydrous contact lens having excellent properties obtained by the method. [Constitution] Polysiloxane macromonomer and (meth) A water-containing contact lens made of a copolymer containing at least an acrylamide monomer and a silicon-containing monomer selected from the group consisting of a silicon-containing alkyl (meth) acrylate and a silicon-containing styrene derivative, oxygen gas and / Alternatively, the plasma treatment is performed in a carbon dioxide gas atmosphere. |
