Abstract

This method of laminating a functional film onto an optical article includes: thermoforming the functional film so as to provide the functional film with a predetermined target curvature based on a curvature of a face of the optical article on which the functional film is to be applied; applying the functional film onto that face of the optical article; pressing the functional film against that face of the optical article so as to adhere the functional film to that face of the optical article. This method further includes heating the functional film at at least one predetermined temperature after the applying, so that the functional film conforms to the curvature of that face of the optical article.
