Abstract: Disclosed is a method of manufacturing an ophthalmic lens having at least one optical function, including the determination of a transmission spectrum in a wavelength range from 280 to 2000 nm, the determination of a matrix including at least two compounds absorbing light having a wavelength from 280 to 2000 nm, with regard to the determined transmission spectrum, and additively manufacturing the matrix.

Abstract: The invention concerns a method for producing an optical article suitable for edging comprising an antifouling layer on which there is deposited a temporary overlayer for assisting with edging, comprising: depositing, on an optical substrate, an organic antifouling layer comprising at least a fluorinated polymer compound comprising hydrolysable functions; and depositing, on the antifouling layer, an overlayer for assisting with edging, of mineral nature, comprising one or more metal fluorides and/or one or more metal oxides or hydroxides; method characterised in that it further comprises a step of accelerated grafting of the antifouling layer chosen from: (a) a treatment of the deposited antifouling layer in a humid atmosphere of the deposited antifouling layer and (b) a catalytic treatment in the acidic or basic vapour phase of the deposited antifouling layer.

Abstract: The invention pertains to an optical device comprising a substrate with two main faces, and, on at least one face, a first coating which is in contact with a second coating, the first coating being positioned between the second coating and the substrate, the first coating is a release layer, adapted so that it can be selectively activated in order to diminish mechanical properties or adhesion enabling the second coating to be fastened to the substrate.
