    • 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.
    • 本发明涉及一种用于转换必须通过制造方法制造的初始渐进式眼表面的方法,所述变换方法包括:选择要实施的制造方法的步骤,其中所述制造方法引入可再现的表面 缺陷,选择所述可再现表面缺陷的预测模型的步骤,选择要制造的初始渐进式眼表面S的步骤,确定(S1)的步骤,其中通过所述预测模型确定 ,如果通过所述制造方法制造初始渐进式眼表面S将引入的表面缺陷值D,其中所述初始渐进式眼表面S通过变形步骤(S2)转化为转化的进行性眼表面S *,转化步骤 补偿在步骤(S1)期间确定的缺陷值D,使得随后的 通过所述制造方法制造转化的眼科表面S *可以获得基本上符合初始渐进式眼表面S的渐进式眼表面。
