Abstract: Disclosed is a method for manufacturing an ophthalmic article including a substrate and a functional wafer securely fastened to a first curved face of the substrate, the manufacturing method including the steps of providing the functional wafer preformed according to a first desired shape, the preformed functional wafer having a first preformed face intended to be applied on the first curved face of the substrate, the first preformed face being defined by first geometrical characteristics; determining second geometrical characteristics of the first curved face of the substrate to be manufactured according to the first geometrical characteristics of the first preformed face of the preformed functional wafer; manufacturing the first curved face according to the second geometrical characteristics determined; fixing the preformed functional wafer to the manufactured substrate by applying the first preformed face on the first curved face in order to form the ophthalmic lens.

Abstract: The invention relates to a method for determining an usage index value for an single-vision ophthalmic lens adapted to correct the vision of a myopic wearer. According to the invention the method comprises: an optical profile providing step S1 during which an optical profile of said ophthalmic lens is determined; a material profile providing step S2 during which a material profile of said ophthalmic lens is determined; a physical parameter determining step S3 during which at least one physical parameter among physical parameters of said optical profile and material profile is determined; a gain assessing step S4 during which at least two gains brought by at least one determined physical parameter is evaluated on at least one evaluation criterion of dissatisfaction of said wearer when wearing said ophthalmic lens; an usage index value determining step S5 during which a value of an usage index is determined by adding the assessed gain for the evaluation criteria.
