Abstract: A substrate having at least one main surface comprising a first coating deposited on said main surface and a second coating having anti-soiling properties deposited and adhering on the surface of said first coating, the first coating being a (meth)acrylate based coating and being obtained by polymerizing a polymerizable composition comprising: i) at least one (meth)acrylate compound and ii) at least one compound I having at least one —M—Z′ bond with M representing Si or a Metal atom, Z′ representing OH or a hydrolysable group, and at least one ethylenic unsaturated group or epoxy group, and/or iii) at least one silica or metal oxide colloid having free ethylenically unsaturated groups; and the second coating, having anti-soiling properties, being obtained by depositing on said first coating an anti-soiling coating composition comprising at least one compound II, or a hydrolyzate thereof, having at least one —Si—Z″ group with Z″ representing OH or a hydrolysable group.

Abstract: The surface of an ophthalmic lens is polished by applying a layer of resin with a surface roughness 30-800 Ra A process for finishing the surface of a prescribed ophthalmic lens by applying a surface layer of resin of thickness 30 to 800 Ra, where Ra = the arithmetical average surface roughness, to confer a polished surface. An Independent claim is included for equipment to provide the surface finish comprising a resin applicator, which comprises a support (1001) in which the lens can be place and rotated and an arm (1003) carrying a nozzle (1002) which provides resin at a low pressure and can be moved vertically and horizontally with respect to the support (1001)

Abstract: A method and coating used to prepare a photo chromically-enabled bifocal ophthalmic lens. The method and equipment includes injection molding a single vision lens (10e), for example, from polycarbonate. The clamp opens vertically and the top insert (20) is exchanged for a bifocal mold (30) having a base curve similar to the single vision lens. The thermos et coating includes compounds from several acrylate classes, and is applied to the single vision lens. The coating may include a photochromic dye. The coating is also formulated to receive a photochromic solution through an imbibition process.
