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: The tool includes a base including a rigid carrier and a flexible collar encircling the rigid carrier; an elastically compressible interface; and a flexible buffer including a central portion that is located in line with the rigid carrier and a peripheral portion that is located transversely therebeyond. This peripheral portion is connected to the carrier exclusively via the interface and via the collar, wherein the collar is configured so that the tool is elastically deformable between a rest position that it adopts in the absence of stress and a reference position in which the transverse end second surface of the flexible buffer is pressed against a reference surface that is spherical and of radius included between 40 mm and 1500 mm.
