发明名称 Method and System for Producing an Ophthalmic Lens
摘要 A method for producing an ophthalmic lens, comprising an additive manufacturing step (100) for producing an intermediate optical element by depositing a plurality of elements of predefined volume of at least one material, said element comprising a target ophthalmic lens supplemented with at least one overthickness, and a flexible polishing manufacturing step (300) for producing said lens from said element by at least partially subtracting the overthickness so as to filter irregularities formed on said element during said additive manufacturing step; said additive manufacturing step comprising a step of defining a manufacturing setpoint for said element in which said overthickness is defined on the basis of predefined parameters of said flexible polishing step, i.e., a geometric characteristic representative of a spatial cutoff frequency and a geometric characteristic representative of a material removal capacity.
