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: A film structure comprising at least a functional film (212), a carrier layer (20), and a counter-force liner (22), said a functional film (212) being in between said carrier layer (20) and said counter-force liner (22). The carrier layer (20) and the counter-force liner (22) are larger than the receiving area, and the film structure comprises fastening means adapted to fasten, directly or indirectly, the counter-force liner (22) to the carrier layer (20) at least on a portion of a zone outside the functional film (212). 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: 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 centre 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: 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.

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: Disclosed is an ophthalmic device having adjustable filtering properties, including at least one polarizer and at least one half-wave plate that is rotatable with respect to the polarizer to thereby adjust the filtering properties for a polarized beam of light that successively meets the half-wave plate and then the polarizer.

Abstract: The disclosure relates to an optical element intended to be worn in front of an eye of a human wearer. The optical element includes a dye composition configured so that, when the optical element is worn by a wearer having a given skin reflectance and is illuminated by a light source from a scene: —a first light beam is transmitted by the optical element towards the wearer, the first light beam having a first chroma; —a second light beam is transmitted by the optical element towards the scene after being reflected by the skin of the wearer, the second light beam having a second chroma; and —the absolute difference between the second chroma and the first chroma is greater than 6.

Abstract: An optical article partially transmits polarized glare in tunable colors that help a user to see surface contours, while enhancing the color and at the same time maintaining the appearance of the lens still neutral.
