Abstract
Disclosed is a method for manufacturing an ophthalmic lens including a substrate and a functional film securely fastened to a curved face of the substrate. This method includes a method for gluing the initially flat functional film to the curved face. To ensure that the functional film when securely fastened to the curved face filters a preset band of wavelengths centered on a wavelength denoted λp, multiple functional films are preselected; two knowledge bases are established experimentally; a film is selected, using the two knowledge bases, from the plurality of preselected films, the wavelength λi' on which is centered the band of wavelengths that this film filters for a certain degree of deformation being equal to λp when the degree of deformation is that given for the curvature in question; and the gluing method is implemented in order to securely fasten the selected film to the curved face.
