Abstract: The invention pertains to an optical device comprising a substrate with two main faces, and, on at least one face, a first coating which is in contact with a second coating, the first coating being positioned between the second coating and the substrate, the first coating is a release layer, adapted so that it can be selectively activated in order to diminish mechanical properties or adhesion enabling the second coating to be fastened to the substrate.

Abstract: An ophthalmic lens that can be edged, includes a main front surface and a main rear surface, obtained by successive deposition on at least one of the main surfaces of the lens, of a first hydrophobic layer that has a thickness of between 6 and 16 nm and is obtained by deposition of a composition including a constituent A selected from fluorosilanes having a number average molar mass that is higher than, or equal to, 2000 g/mol, of a second hydrophobic layer that has a thickness of between 3 and 20 nm and is obtained by the deposition of a composition including a constituent B selected from the fluorosilanes having a number average molar mass than is lower than, or equal to, 900 g/mol, and of a layer including a metal fluoride having a thickness of between 22 and 50 nm.

Abstract: The present invention relates to an optical article comprising a substrate, and, from the substrate upward: an organic antistatic coating comprising at least one conductive polymer, an adhesive and/or impact-resistant primer coating deposited onto said antistatic coating, and an abrasion-resistant and/or scratch-resistant coating deposited onto said adhesive and/or impact-resistant primer coating. The optical article has very short static charge dissipation times and its antistatic properties are stable over time.
