| titleOfInvention | Contact lens |
| abstract | A contact lens contains a copolymer obtained by copolymerizing, as an indispensible feed monomer, 2 to 95 wt.% of a carboxylic acid ester monomer and 98 to 5 wt.% of a copolymerizable monomer. The carboxylic acid ester monomer is represented by the formula (I) nCH₂ = - COO(CH₂) n - R₁ (I) n nwherein R₁ stands for a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, an alkenyl group having 1 to 12 carbon atoms, a cyclic alkyl group having 3 to 12 carbon atoms or an aryl group, and X stands forn in which R₂ and R₃ each stand for a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, an alkenyl group having 1 to 12 carbon atoms, a cyclic alkyl group having 3 to 12 carbon atoms or an aryl group, m and l being integers of from 0 to 4, at least one of R₁, R₂ and R₃ being a group containing a fluorine atom and n being an integer of from 0 to 4. |
