Abstract

La présente invention concerne les lentilles résistant à l'abrasion. Les substrats d'éléments optiques sont revêtus d'une couche de liaison formée par un A-alkylènealkoxysilane, où A contient un groupe réagissant avec le substrat, pour être ensuite revêtus par revetement résistant à l'abrasion du type décrit dans le brevet des EUA, 3.986.997. Les substrats obtenus servent à fabriquer des lentilles ophtalmiques.
