  • Method of manufacturing an ophthalmic lens
    Patent number: 12529909
    Abstract: Disclosed is a method of manufacturing an ophthalmic lens to be mounted into a frame, including: a step of acquiring an optical prescription for the future wearer of the ophthalmic lens and an information relative to the ophthalmic lens and/or to the future wearer and/or to the frame; a step of calculating a surfacing instruction of the ophthalmic lens, the surfacing instruction being determined SO that the ophthalmic lens once surfaced satisfies the optical prescription; and a step of surfacing during which the at least one optical face of the ophthalmic lens is surfaced according to the surfacing instruction. During the step of calculating, the surfacing instruction is calculated so that the optical face of the ophthalmic lens once surfaced includes a mark that results from the step of surfacing and that forms a code associated with the information.
