Abstract: 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.

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.

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%.

Abstract: 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.

Abstract: The object of this invention is to provide optical articles having one or more transmittance-attenuating dyes. Each dye attenuates transmission of a certain wavelength range. Different dyes can be combined in different concentrations to tune the transmittance spectrum through a lens. The transmittance-attenuating dyes can be incorporated into different optical articles using different production methods.

Abstract: The optical articles disclosed herein render polarized glare in a certain tunable color that is visually more perceptive than a regular tinted lens or a regular polarized lens. Optical articles, including sunglass lenses, that are configured to color plane-polarized light transmitted through the lens will draw the wearer's attention and help identify the contours or dangers on surfaces in the wearer's field of vision.
