Abstract
The invention concerns a method for obtaining an ophthalmic lens comprising a surface utility microstructure, in 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.
