Abstract
A method for manufacturing an ophthalmic element that comprises a vision base element (12) and a film structure (14) adhered to said vision base element allows limiting or suppressing wrinkles and delaminations. This method implements an auxetic part (27) within a sacrificial film portion (26) that belongs initially to the film structure. In this way, stresses generated in a useful area (24) of the film structure by the sacrificial film portion are reduced. The sacrificial film portion is then removed so that only the useful area of the film structure remains in the ophthalmic element.
