  • Surface-treated contact lens and method of producing
    Patent number: 4666249
    Abstract: A contact lens for correction of astigmatism is formed from a single polymeric or copolymeric material. The lens has a central optical zone of greater rigidity than a surrounding non-optical zone. The rigidity of the central optical zone is sufficient for it to retain an astigmatism-correcting shape when worn on an eye, while the surrounding non-optical zone conforms to the shape of the eye.
