Abstract
Official abstract text for this publication.
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 (S 1 ), 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 (S 2 ), 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 (S 1 ), 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for transforming an initial progressive ophthalmic surface which has to be manufactured by a manufacturing method, the transformation method being implemented prior to an actual manufacture of the progressive ophthalmic surface and comprising: a step of selecting a manufacturing method intended to be implemented on the basis of characteristics of the progressive ophthalmic surface to be manufactured after the transformation method, in which sa…
