Comfortable, oxygen permeable hard and semi-hard contact lenses are made from the copolymer of an ethylenically unsaturated siloxanylalkoxy ester monomer, an ethylenically unsaturated fluorocarbon ester monomer and an ethylenically unsaturated sulfone monomer. The copolymer plastic can be modified by the incorporation of hardening, stability and wettability agents. Also disclosed herein are methods for the manufacture thereof. |
