  • Patent number: 12097719
    Abstract: The invention relates to a process for marking an optical eyeglass (1) equipped with a surface coating (5) comprising the following steps: A step of detreating by means of a laser beam, so as to locally detreat an area of the optical eyeglass by removing the surface coating (5) until a lower layer (7) of the eyeglass (1) is reached, which layer is located under said coating (5) and made of a material that is different from the surface coating (5), thus forming at least one the detreated zone (6, 11), A step of depositing an ink (9) in the detreated zone (6, 11) in order to form at least one inked pattern (4), so that the ink (9) adheres to the lower layer (7) present at the bottom (10) of the detreated zone (6, 11).
