Abstract

Provided are rigid contact lenses having high oxygen permeability and methods to make the same. The rigid contact lenses comprise a polyacetylene. Also provided are methods of making rigid high oxygen permeability contact lenses.

Claims (8)

1. A rigid contact lens having high oxygen permeability and a uniform composition comprising a PTMSP polyacetylene wherein the oxygen permeability of the lens is above 50 barrers, wherein the contact lens is molded to a rigid contact lens shape and allows some oxygen to pass through the lens to the cornea when in use, said lens made by the method comprising:

providing a solution of a PTMSP polyacetylene and t-butyl styrene, forming a polyacetylene blend;

polymerizing the polyacetylene blend, forming a polymerized polyacetylene blend;

forming a contact lens from the polymerized polyacetylene blend.

2. A rigid contact lens having high oxygen permeability and a composition comprising a PTMSP polyacetylene wherein the oxygen permeability of the lens is above 50 barrers, wherein the contact lens allows some oxygen to pass through the lens to the cornea when in use, said lens made by the method comprising:

providing a solution of a PTMSP polyacetylene and t-butyl styrene, forming a polyacetylene blend;

polymerizing the polyacetylene blend, forming a polymerized polyacetylene blend;

forming a contact lens from the polymerized polyacetylene blend.
