<p>PCT No. PCT/JP83/00237 Sec. 371 Date Mar. 19, 1984 Sec. 102(e) Date Mar. 19, 1984 PCT Filed Jul. 25, 1983 PCT Pub. No. WO84/00619 PCT Pub. Date Feb. 16, 1984.The oxygen-permeable hard contact lens of this invention produced by polymerizing in a composition composed of 30 to 50% by weight of an alkyl (meth)acrylate, 10 to 40% by weight of a fluorine-containing monomer, 10 to 35% by weight of a silicone (meth)acrylate, 5 to 15% by weight of an unsaturated carboxylic acid and 0.1 to 15% by weight of a di- or tri(meth)acrylate of a dihydric or higher hydric alcohol by raising a temperature continuously or stepwise from 40 DEG to 100 DEG C. and processing the resulting polymer into a lens shape by ordinary mechanical processing and polishing, is excellent in stain resistance, scratch resistance and hydrophilicity.</p> |
