Abstract: The present invention relates to a method for transforming an initial progressive ophthalmic surface which has to be manufactured by a manufacturing method, the transformation method comprising: • a step of selecting a manufacturing method intended to be implemented, in which said manufacturing method introduces a reproducible surface defect, • a step of selecting a predictive model of said reproducible surface defect, • a step of selecting an initial progressive ophthalmic surface S intended to be manufactured, • a step of determining (S1), during which there is determined, by means of said predictive model, a surface defect value D which would be introduced if the initial progressive ophthalmic surface S were produced by said manufacturing method, • a transformation step (S2), during which said initial progressive ophthalmic surface S is transformed into a transformed progressive ophthalmic surface S* by compensating the defect value D determined during the step (S1), such that the subsequent manufacture of the transformed ophthalmic surface S* by said manufacturing method makes it possible to obtain a progressive ophthalmic surface which substantially conforms to the initial progressive ophthalmic surface S.

Abstract: L'invention concerne un procédé de fabrication d'une lentille optique comportant les étapes de fournir un palet (1) qui présente une face supérieure et une face inférieure (33) pour former des première et deuxième faces (2) de lentille, une tranche (4) formant un premier repère mécanique de positionnement et une portion en rampe (5) ménagée entre ladite tranche et ladite face supérieure qui forme un deuxième repère mécanique de positionnement ; fournir une bague de positionnement (10) comportant une cavité définissant un contour interne (20) concentrique avec ladite tranche qui forme un premier repère complémentaire de contrôle et un épaulement (21) formant un deuxième repère complémentaire de contrôle ; emboîter ledit palet dans ladite cavité, ladite tranche étant en contact avec ledit contour interne et ladite portion en rampe étant en contact avec ledit épaulement ; et bloquer en position ledit palet sur un pion de blocage et de maintien, ladite bague y étant alors interposée.
