Abstract: The invention concerns a method for obtaining an ophthalmic lens comprising a surface utility microstructure, in particular antiglare. The method for obtaining an ophthalmic lens comprising a surface utility microstructure consists in a step for transferring the microstructure into the lens surface from a mould whereof the internal surface bears the microstructure and has a sight correcting geometric design, the microstructure being initially determined by an interferential process. The invention is useful for making ophthalmic 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)
