The present invention addresses the problem of providing a colored contact lens which eliminates discomfort that arises when the color of the pupil of the wearer's eye and the colored pattern of the lens are simultaneously seen. This colored contact lens is characterized by comprising a copolymer obtained by copolymerizing a monomer mixture that comprises 30-99.5 parts by weight of a hydroxylated (meth)acrylate, 0-15 parts by weight of a (meth)acrylamide monomer and/or an N-vinylamide, 0-1 part by weight of a carboxylated monomer, and 0-70 parts by weight of other desired monomer(s). The colored lens is further characterized in that the difference between the lens diameter at 35ºC and the lens diameter at 20ºC is 0.5 mm or less and the difference between the lens diameter at pH 7.0 and the lens diameter at pH 3.0 is 0.5 mm or less. |
