Disclosed is a method for manufacturing an optical lens including the following successive steps: a step of providing an optical lens attached to a blocking piece; a step of laminating a functional film on a surface of the optical lens; a step of obtaining an assembly constituted by the blocking piece, the optical lens and the functional laminated film; a step of cutting the excess film directly on the assembly, so as to reduce the film shape; and a step of deblocking the optical lens with the film, and the blocking piece.

A molding device for casting an optical article with a thermoset resin the optical article defining two opposed main surfaces, one of which being formed by an optical functional wafer, the molding device comprising: —a. a molding element () forming a rear or a front part of a casting mold —b. a gasket () intended to surround the molding element —c. an initially curved wafer () defining a predetermined curvature depending on one of the two main surfaces of the optical article to be molded —d. a closing element () defining in a closing position in which the peripheral part of the wafer on the gasket is pinched, a pouring space between the molding element, the gasket and the wafer —e. spacing means () interposed between the wafer and the molding element to define an internal volume between the wafer and the closing element, the spacing means, wafer and closing element being configured to form a set hermetic to the resin to be poured into the molding device the closing member occupies a closing position.

A machine for transferring a preformed functional film onto a curved face of an ophthalmic substrate, including: a first device for receiving and holding the substrate; a second device for receiving the film, the first device and/or second device configured to hold the film by applying a pressure force to the periphery thereof; a first mechanism for moving the devices, configured to place the curved face such that it faces the film, a second mechanism for moving the devices, configured to bring into contact the center of the film with the center of the curved face and to apply the film with the substrate to radially spread, from the center of the film up to the periphery thereof, a conformal contact between the film and the curved face; and a control and command unit configured to control at least the second mechanism when the film and the substrate are in contact.
