OXYGEN-PERMEABLE HARD CONTACT LENS

摘要

A process for making gas-permeable hard contact lens. The prepd. mixt. was composed of alkyl (meta) acrylate 30-50 wt.%, the monomer containing fluorin 10-40 wt.%, silicon (meta) a crylate 10-35 wt.%, unstd. carboxylic acid 5-15 wt.%, di (meta) acrylate or tri (meta) acrylate of alcohol 0.1-15 wt.%. This mixt. was polymerized in a mold to form the lens. The resulting lens are oxygen permeable, pollution resistant, non-damaging and have hydrophilic properties.
