Abstract: A method for manufacturing an ophthalmic element that comprises a vision base element (12) and a film structure (14) adhered to said vision base element allows limiting or suppressing wrinkles and delaminations. This method implements an auxetic part (27) within a sacrificial film portion (26) that belongs initially to the film structure. In this way, stresses generated in a useful area (24) of the film structure by the sacrificial film portion are reduced. The sacrificial film portion is then removed so that only the useful area of the film structure remains in the ophthalmic element.

Abstract: A method for controlling an ophthalmic system including at least one optical element, at least one measuring sensor, at least one interface for communication with a communicating external electronic device, and at least one processor connected to the optical element and used to control a variation of a functionality relating to the optical element. The method includes: obtaining at least one measurement using the sensor, selecting at least one piece of information obtained by a communicating external electronic device, determining an instruction based on the measurement acquired by the sensor and the information obtained by the communicating external electronic device, and executing the instruction by the processor to control the variation of the functionality relating to the optical element.

Abstract: Disclosed herein is a method for obtaining a material comprising mesogenic compounds forming a liquid crystal mix with a stabilized blue phase. The method includes the steps of a) inducing the liquid crystal mix, contained in a chemical composition, to form the blue phase, then b) illuminating the chemical composition with a light beam of visible wavelength in order to trigger the polymerization of monomers contained in the chemical composition, to obtain the material comprising the liquid crystal mix in the blue phase stabilized by the polymerized monomers. The chemical composition contains a mesogenic system and a chemical photo-initiator system adapted to trigger the polymerization of the monomers when illuminated by the light beam of visible wavelength, in which the mesogenic system includes the mesogenic compounds forming the liquid crystal mix, a chiral dopant adapted to induce the blue phase, and a monomer mix comprising the monomers adapted to polymerize.

Abstract: An ophthalmic element includes a vision base element and a film structure that is adhered to an optical surface of the vision base element, so that the film structure conforms to the optical surface. The film structure comprises at least one auxetic film that has a negative Poisson ratio. Using an auxetic film suppresses wrinkles, cracks and delamination that may appear in the ophthalmic element when the optical surface is synclastic.

Abstract: A spectacle lens includes an activable optical filter having at least an electrochromic device and being configured to be actively switched between at least three configurations. In the first configuration, the activable optical filter is uniform. In the second configuration, the activable optical filter attenuates selectively light from a localized light source. In the third configuration, the activable optical filter is uniform. Furthermore, the chromaticity difference ΔChrom between each of the configurations is smaller than or equal to 20.
