ABSTRACT:
Coated synthetic resin lenses having a primer layer of a copolymer of an acrylic and/or methacrylic monomer and an aromatic vinyl compound between the base material and a cured abrasion resistant layer of colloidal silica and an inorganic anti-reflection coating are provided. The cured coat of colloidal silica has a particle diameter between about 1 and 100 millimicrons and is dispersed in a hydrolyzed silane compound. The organic primer coating improves adhesion properties between the base material and the cured abrasion-resistant layer resulting in coated lenses of improved impact resistance.
