| titleOfInvention | Hydrous soft contact lens |
| abstract | (57) [Summary] [Purpose] High water content, excellent oxygen permeability, and excellent shape stability suitable for thin contact lenses. To provide a hydrous soft contact lens having high mechanical strength and high hardness. [Structure] A polymer having one or more polymerizable groups in the molecule, which is obtained by copolymerizing a copolymerization component (I) containing an alkyl (meth) acrylate (A) and a crosslinking agent (B) as main components. Component (A), (meth) acrylamide 60 to 90% by weight And a copolymerization component (II) containing a hydrophilic monomer (C) consisting of 10 to 40% by weight of N-vinyllactam, and the amount of the component (A) in the copolymerization component (I). Is from 5 to 50% by weight of the total amount thereof, the copolymerization component (II) is from 35 to 60% by weight of the component (A), and from 0.01 to 1 of the component (B). A hydrous soft contact lens containing 40% to 65% by weight of the component (C). |
