A contact lens made from a copolymer prepared from a monomer mixture comprising perfluorooctylethyloxyalkylene (meth)acrylate, siloxanyl (meth)acrylate, alkyl methacrylate, a hydrophilic monomer, and a crosslinking agent as the indispensable components. This lens has good oxygen-permeability, hardness, and wettability with water, thus being quite useful practically. |
