Abstract: The method comprises: a) placing in contact at least one principal surface of the colourless articles of the set with a solution of a fluorescent material for a sufficient time to allow penetration of the fluorescent material under the principal surface of the article; b) irradiation of the impregnated articles by means of radiation which activates the fluorescence of the fluorescent material; and c) selection of the articles in the set into two sub-sets of which the first is composed of those articles of the set which show a homogeneous fluorescence of their principal surfaces under irradiation and the second is composed of those articles of the set which show a non-homogeneous fluorescence of their principal surfaces under irradiation. Application: to opthalmic lenses.

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.
