| 摘要 |
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. |
