Abstract
The method for manufacturing relates to an ophthalmic lens comprising a substrate and a functional film securely fastened to a curved face of said substrate. This method comprises a method for gluing the functional film, which is initially flat, to said curved face. The interferential and organic filtering film selected as said functional film filters a preset band of wavelengths and the gluing method is carried out so that the maximum of the degree of major deformation experienced by the film on a surface is lower than 3%. In the ophthalmic lens, the wavelength at which maximum filtration is observed at the center of the lens and the wavelength at which maximum filtration is observed at the periphery of the useful area of the lens differ by a less than 5%.
