Abstract: Method for the manufacture of an optical article comprising the following steps: - providing a substrate having two main faces and bearing -OH functions on at least one of its faces, - successively exposing in this order one face of the substrate bearing OH functions to at least 3 distinct materials named M1, M2, M3 and optionally material M4 in a vacuum chamber under conditions resulting in the deposit of those materials on the surface of the substrate, and wherein: - M1 is a substituted silane comprising at least one function X1 directly bonded to a Si atom of the substituted silane, wherein the Si-X1 group is capable of forming a covalent bond with a OH group of the substrate, X1 being preferably a hydrolysable group (such a NH2 group) or a -OH group directly bonded to the silicon atom and comprising at least one fluorine containing group, - M2 is a substituted silane of number average molecular weight inferior or equal to 900 g/mol comprising at least one function X2 directly bonded to a silicon atom of said substituted silane wherein the Si-X2 group is capable of forming a covalent bond with a OH group of the substrate and/or a covalent bond with M1, X2 being preferably a hydrolysable group (such a NH2 group) or a OH group and at least one hydrophobic or oleophobic group, or at least one hydrophilic group, - Wherein M1 has a weight average molecular weight higher than M2 and the difference between M1 and M2 weight average molecular weights is equal to or higher than 600 g/mol, preferably equal to or higher than 900 g/mol. - M3 is a metal fluoride, - Optional M4 is a non fluorinated metal oxide or metal hydroxide.

Abstract: A process is provided where at least one main face of an optical lens is subjected to a corona discharge or atmospheric plasma treatment. The optical lens is dipped in a curable coating composition to deposit a layer of the curable coating composition on said main face, and is then cured. During the whole process, the optical lens is carried by a same lens holder so that the lens face is freely accessible and without necessitating manual handling of the lens.

Abstract: A process for edging an optical lens for conforming the optical lens to the size and shape of a lens frame into which the optical lens is to be accommodated, said process comprising: a) providing an optical lens having a convex surface, the convex surface being provided with an anti-smudge topcoat rendering the optical lens inappropriate for edging; b) fixing a mounting element on the convex surface of the optical lens, preferably on its center, by means of an adhesive pad adhering both to the mounting element and the convex surface of the optical lens to form a mounting element/optical lens assembly; c) placing the mounting element/optical lens assembly in a grinding machine so that the optical lens is firmly maintained; and d) edging the optical lens to the intended size and shape, wherein, prior to step (b) of fixing the mounting element, the anti-smudge topcoat on the convex surface of the optical lens is pre-treated with a solvent selected from the group consisting of alkanols and dialkylketones under a mechanical stress.

Abstract: The invention relates to a process for depositing an anti-fouling top coat onto the outermost coating layer of a coated optical article, comprising the following steps: a) providing an optical article having two main faces, at least one of which being coated with an outermost layer; b) treating said outermost layer with energetic species resulting in surface physical attack and/or chemical modification; and c) vacuum evaporating a liquid coating material for an anti-fouling top coat by means of an evaporation device, resulting in the deposition of the evaporated coating material onto the treated outermost layer of the optical article, wherein prior to the vacuum evaporation step of the liquid coating material, said liquid coating material has been treated with energetic species.

Abstract: An apparatus for dip coating lenses comprises a tank for containing a coating liquid, a coating chamber for receiving one or more ophthalmic lenses. The tank is in fluid communication with the coating chamber for permitting the flow of coating liquid between the tank and the coating chamber. The apparatus has a first position where the coating chamber is located above the tank and second position where the tank is located above the coating chamber.
