Contact lens material |
| abstract |
A contact lens material comprising a copolymer obtained by polymerizing monomer components consisting essentially of 45 to 70 parts by weight of a silicone-containing monomer represented by the general formula (I): wherein l is 0 or 1, and m and n are a integer from 1 to 15, and from 20 to 45 parts by weight of an alkyl (meth) acrylate, in which an alkyl group has 1 to 6 carbon atoms and at least one hydrogen atom in the alkyl group is substituted by a fluorine atom, and from 5 to 15 parts by weight of a crosslinking agent. wherein the total residual amount of unpolymerized monomer component remaining in the copolymer based on the copolymer is at most 3.5% by weight, the oxygen permeability coefficient of the copolymer is at least 130 x 10-11 (cm2 / s ) * (mlO2) / (ml * mmHg), and the water absorption ratio of the copolymer is at most 0.3% by weight. |
