Abstract: PROBLEM TO BE SOLVED: To provide a composition suitable for an oxygen permeable hydrous contact lens that can avoid using an organic solvent which will impair the strength of a polymer in copolymerization reaction and that can avoid modifying a polymer surface after copolymerization reaction.SOLUTION: A curable composition for an oxygen permeable hydrous contact lens comprises: (i) a monomer represented by the general formula (I) (where R1 is an acryloyloxy group or methacryloyloxy group, R2 is a four- to eight-membered cyclic hydrocarbon group, R3 is a hydrophilic group or a linear or branched C1-4 alkyl group substituted with one or more hydrophilic groups, R4 is a silicon-containing group, and e is 1 or 2); (ii) a hydrophilic monomer; and (iii) a silicon-containing monomer.
