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.

Abstract: A polarized optical article is manufactured by introducing ultraviolet absorber into the coating by imbibition. The imbibition comprises immersion of the article in an aqueous solution comprising the UV absorber and dispersing agent(s), for 10 seconds - 2 minutes. The solution is kept at 80-99[deg]C. The article is rinsed with a lower alcohol. Manufacturing a polarized optical article, in particular a polarized ophthalmic lens, comprises applying, to a substrate of the optical article, a polymerized coating comprising dye(s) that is sensitive to photodegradation, and introducing a UV absorber into the coating. The polymerized coating comprising dye(s) that is sensitive to photodegradation is a bilayer coating comprising a first layer of linear photopolymers (LPP) and a second layer of liquid crystal polymers (LCP) comprising dichroic dye(s). The UV absorber is introduced into the coating by imbibition. The imbibition comprises immersion of the article in an aqueous solution comprising the UV absorber and dispersing agent(s), for 10 seconds to 2 minutes. The solution is kept at 80-99[deg]C. The article is rinsed with a lower alcohol.
