A water-absorptive soft contact lens comprising a polymer prepared by polymerizing a monomer mixture comprising, as main components, (A) 25 to 75% by weight of a (meth)acrylamide monomer, (B) 20 to 70% by weight of a fluoroalkyl (silicon-containing alkyl) fumarate, and (C) 0.01 to 10% by weight of a crosslinkable monomer. The water-absorptive soft contact lens has excellent oxygen permeability and high mechanical strength independent of water content, and is excellent in transparency and shape stability. |
