Abstract
This invention is primarily directed to edged three-layer ophthalmic lenses having a coating covering the edge of the lens. The coating provides a cushion between the lens and an eyeglass frame and inhibits the penetration of moisture and tints commonly used to fashion tint ophthalmic lenses. The coating comprises a dimethyl silicone coblocked with vinyl with crosslinking therein being provided through a platinum-catalyzed addition reaction. The inventive coating also imparts advantageous properties to single element glass and plastic lenses.
