METHOD FOR STICKING A FILM ONTO A CURVED SUBSTRATE.

摘要

A method sticks onto a curved surface of a substrate a functional film (4) that has a substantially planar initial shape. To this end, the film (4) is retained on a deformable membrane (1) by connecting means (2) that allow portions of said film to slip relative to the membrane when said membrane is deformed. This reduces stresses that are created in the film by the deformation. The method is adapted for applying a functional film to an ophthalmic lens.
