摘要： Disclosed is a semi-finished lens that includes a blank formed in a first material having a first hardness, the blank having an outline, a first face and a second face configured to be surfaced so as to constitute a first optical face of the ophthalmic lens, and a top layer formed in a second material having a second hardness greater than the first hardness, the top layer having an outline, a first face and a second face, the second face of the top layer being arranged on the first face of the blank. The outline of the top layer is equal to or included in the outline of the blank, and satisfies to a predetermined dimensional selection criterion involving the final outline of the ophthalmic lens.

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.
