    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: L'invention concerne un procédé de détourage d'une lentille ophtalmique (100) multicouche suivant un contour souhaité, comportant : - une étape de pré-ébauche de la lentille ophtalmique au moyen d'un outil préliminaire, selon un contour préliminaire, - une étape d'ébauche de la lentille ophtalmique au moyen d'une meule d'ébauche, suivant un contour d'ébauche, et - une étape de finition de la lentille ophtalmique au moyen d'un outil de finition, Selon l'invention, ledit contour préliminaire est élargi par rapport au contour souhaité, et la meule d'ébauche utilisée présente une granulométrie comprise entre 0,1 et 0,5 mm et est pilotée relativement à ladite lentille ophtalmique de manière à appliquer au cours de ladite étape d'ébauche une force radiale sur la lentille ophtalmique comprise entre 0,1 et 5 N.
