Abstract: The invention relates to an improvement for applying a layered structure (1) onto a convex surface of a lens (10). After thermoforming the layered structure, a curvature direction of the layered structure is inverted. The structure is then applied on the lens surface by continuously pushing the structure (1) against the lens surface, starting from a contact point between a convex surface of the structure and the convex surface of the lens. The curvature direction of the layered structure is then inverted again, so that it recovers the curvature direction that resulted from thermoforming. Stresses within the layered structure are then reduced, and the structure can be assembled with the lens without defects.

Abstract: A transparent and polarizing vision element (2) divided into several areas. At least two of said areas are associated with a luminous polarization filter. The light flowing through the element is allocated differently for two the areas according to a direction of polarization of the light. At least one polarization filter is oriented vertically, and at least one polarization filter is oriented horizontally in relation to the usual position of the element.

Abstract: The invention relates to an optical article, for example, an ophthalmic lens, comprising at least one multilayer anti-reflective coating on a transparent substrate made from organic or mineral glass. Said coating comprises successively and starting at the substrate, a layer of material with high refractive index (HI), made from a hybrid organic/inorganic matrix within which are dispersed particles of mineral oxide or chalcogenide with a diameter of 2 to 50 nm and a layer of material with low refractive index (BI), obtained by hardening of a composition comprising at least one silane precursor (I) with 4 hydrolysable groups and at least one fluorosilane precursor (II), said second composition comprising at least 10% in mass of fluorine in a theoretical dry extract and with a molar ratio I/I+II greater than 80%.

Abstract: La présente invention a pour objet un article comprenant un substrat ayant une surface principale revêtue d'un revêtement dont au moins une partie est mésoporeuse et présente un profil d'indice de réfraction à fonction optique, dont la variation est imposée par la teneur en mésopores et/ou le taux de remplissage des mésopores.Le profil peut être tel que l'indice de réfraction varie selon la distance à un axe donné, ou tel que la variation d'indice de réfraction est monotone décroissante suivant tout axe perpendiculaire à la surface du substrat sous-jacente à la partie mésoporeuse dudit revêtement et orienté dans le sens de l'éloignement du substrat.La présente invention a également pour objets des procédés de fabrication de l'article ci-dessus, qui diffèrent selon la technique à partir de laquelle est crée le profil d'indice de réfraction.Application à l'optique ophtalmique.
