Abstract: The invention relates to methods for obtaining the photochromic latex comprising the polymerization in aqueous emulsion of an initial polymerizable mixture, comprising one or more monomers polymerizable by free-radical mechanism and one or more photochromic compounds and the addition to the initial polymerizable mixture, during the polymerization of the initial polymerizable mixture or to the final latex of at least one agent for stabilizing the photochromic properties. Such latexes can be used in the production of photochromic films. Such films may be used, for example, on optical lenses.

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)
