Abstract

Film (1) destiné à être appliqué de manière stratifiée sur un verre ophtalmique (2), et comprenant un film substrat, une couche dure, une couche antireflet, et éventuellement une couche lubrifiée. Ces couches peuvent être appliquées sur le film substrat au moyen de techniques d'application de liquides, telles que le revêtement par centrifugation. Ce film (1) est généralement appliqué de manière stratifiée sur la surface postérieure (3) d'un verre (2) après que la surface de celui-ci ait été traitée dans un laboratoire pour lunettes de prescription. L'utilisation d'un appareil de dépôt sous vide coûteux dans de tels laboratoires n'est de ce fait plus nécessaire.
