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.

A machine and method for obtaining a curved surface of a film structure that comprises a carrier layer and a functional film (). The machine comprises an annular support member having a supporting face adapted for supporting the film structure, and an opening () that is covered by the film structure when said film structure is supported by the annular support member; a clamping system configured to clamp the annular support member and the film structure when supported by the annular support member; and a forming system configured to apply pressure, and preferably temperature, on the film structure so as to curve said film structure in or through the opening () of the annular support member. The opening () of the annular support member has a contour that is non-circular so that the obtained curvature of the functional film () corresponds to a target curvature.

This thermoforming machine includes a thermoforming chamber having at least one heated air inlet through which heated air flows into the thermoforming chamber at a controlled pressure. The air inlet cooperates with a heated air flow distribution regulator located in the thermoforming chamber and through which the heated air flows out of the thermoforming chamber at a predetermined temperature. The regulator includes a heated air flow regulating mask receiving heated air flow, having a plurality of flow restricting elements providing different air flow restrictions.

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.

Disclosed is a lamination machine including: a film support for receiving a functional film to be laminated; an article support configured to receive and position the optical article in a predetermined orientation; and an actuating member configured to move the film support and the article support toward each other for laminating at a predetermined pressure the functional film received in the film support onto the optical article received within the article support. The article support is a blocker support configured to receive a surfacing blocker onto which the optical article is to be disposed for lamination, the article support being further configured to transmit laminating forces induced by the predetermined pressure to the lamination machine during a lamination operation.

A film structure including at least a functional film, a carrier layer, and a counter-force liner, the functional film being in between the carrier layer and the counter-force liner. The carrier layer and the counter-force liner are larger than the receiving area, and the film structure includes a fastener adapted to fasten, directly or indirectly, the counter-force liner to the carrier layer at least on a portion of a zone outside the functional film. It is also proposed a corresponding machine, optical device and method for forming a functional film intended to be laminated on an optical article.

An opaque adhesive can be used to secure the convex surface of a lens blank to a lens blocking piece. This opaque adhesive can include a resin that is curable under ultraviolet light and contains many dispersed pigment particles. The pigment particles may absorb light in the wavelength range of about 300 nm to about 800 nm such that the adhesive appears substantially opaque. A lens-on-block (LOB) system that uses the opaque adhesive to adhere a lens blank to a lens blocking piece facilitates on-block inspection of surface defects by increasing the contrast of light reflected from the surface being inspected. Put differently, the defects in the lens blank's surfaces stand out more when viewed in front of the opaque adhesive The inspection results can be used to carry out rework loops that eliminate or correct the detected defects, providing a streamlined method for on-block manufacturing of ophthalmic lenses.
