Abstract: Process for manufacturing of an optical article which comprises: making available an organic substrate based on an organic polymer having a degree of water uptake of greater than or equal to 0.6% by weight, with respect to the total weight of the substrate, the degree of water uptake being equal to the weight of water absorbed by the material after drying and then storing for 800 hours in a chamber at 50° C. under a relative humidity of 100% and at atmospheric pressure; forming a hard abrasion-resistant coating on the substrate by heating the substrate at a temperature of greater than or equal to 90° C. for a period of time of at least 20 minutes; exposing the substrate covered with the hard abrasion-resistant coating to a humid atmosphere, so as to restore, to the organic substrate, the water evaporated during stage; and depositing of a water-impermeable inorganic coating by vacuum evaporation.

Abstract: A method for marking an ophthalmic lens with a hydrophobic and/or oil-repellent low surface energy outer layer on a high surface energy substrate or coating. The method consists in: positioning a complementary patterning mask of the desired marking between the lens surface to be marked and an energizing discharge source capable of substantially eliminating the outer layer to as to expose the subjacent high energy substrate or coating. The temporary protective layer has a surface energy higher than that of the outer layer and a thickness less than about 5 nm, and preferably between 2 and 4 nm, thereby enabling the discharge to act on the outer layer through the temporary protective layer.

Abstract: The invention concerns a support of the type comprising at least a first base (13), and, borne by the latter, for maintaining such an optical lens (10) at its edge (11), at least three support pins (14A, 14B). The invention is characterized in that the base comprises, for its own support, a plane support surface (16) whereof the peripheral outline (P1) is globally circular, its radial dimension (D1) along a particular radius (R) of said support surface (16) is at least equal to its axial dimension (D2) perpendicularly to the plane thereof. The invention is particularly useful for maintaining an optical lens in a processing apparatus using spin coating technique.
