Abstract: Disclosed is a method for evaluating cosmetic defects of an optical device, including: a first step of acquiring a first set of cosmetic defects of the optical device; a second acquiring step during which a second set of cosmetic defects of the optical device is acquired, the second set of cosmetic defects being different from the first set of cosmetics defects and including at least one cosmetic defect corresponding to a cosmetic defect of the first set of cosmetic defects; a determining step, during which a subset of the first set of cosmetic defects of the optical device is determined based on the comparison of the cosmetic defects of the second set of cosmetic defects and the cosmetic defects of the first set of cosmetic defects; and a determining step, during which a quality factor of the optical device is determined based on the subset of cosmetic defects.

Abstract: A method of preparing an ophthalmic lens (20) for mounting in an eyeglass frame, the ophthalmic lens including a memory mark (28) that is situated on one of its ophthalmic faces (22) and that forms a code storing in digital form at least one item of information relating to a mechanical, geometrical, or optical characteristic of the ophthalmic lens. The method includes three steps: a) acquiring a raw image of at least a portion of the optical face of the ophthalmic lens on which an image of the memory mark appears; b) processing the raw image acquired in step a) in order to decode the information stored in the code; and c) centering and then shaping the ophthalmic lens as a function of the information decoded in step b).
