Use of random copolyester for enhancing impact resistance of an ophthalmic lens and resulting lens

摘要

The invention concerns an ophthalmic lens comprising an organic glass substrate having main front and rear surfaces, at least a primary coat deposited on at least one of the main surfaces of the substrate and an abrasion-resistant coating layer on the primary coat, said primary coat comprising a copolymer or a mixture of random copolymers, selected among C3-C10 alkyl acrylate and C1-C2 alkyl methalcrylate random copolymers. The invention is applicable to spectacle lenses.
