A system for the optical reading of markings printed on an ophthalmic lens (2), includes an image capture device (26), a light source (15) and a support (18, 31) which are configured so that, when the lens is received by the support with a masking element (39) which covers the markings, the source illuminates the lens while rendering the markings visible to the device; and a mobile element on which the source is fixed and which admits a retracted position where it is distanced from the support and a working position where it surrounds at least partially the support and the source looks at the support and these latter are configured so that the source illuminates a rim (34) of the lens so that the light penetrates into its mass (35) and reaches the masking element (33) through the lens. |

1. An optical system for reading marks printed on a face (20) of an ophthalmic lens (2), said system (1) comprising:
an image capturing device (26); a light source (15); and a holder (18, 31) for receiving said ophthalmic lens (2);with said image capturing device (26) and said light source (15) and said holder (18, 31) being configured so that, when said ophthalmic lens (2) is received by said holder (18, 31), said light source (15) illuminates said lens (2), thereby making said marks (21-24) visible to said image capturing device (26);
characterized in that said system (1) furthermore comprises a movable element (14) to which said light source (15) is fastened, which movable element (14) has a working position in which said movable element (14) at least partially encircles said holder (18) and in which said light source (15) faces said holder (18, 31), and a retracted position in which said movable element (14) is located a distance away from said holder (18, 31), with said light source (15) and said holder (18, 31) being configured so that, in said working position, when said ophthalmic lens (2) is received by said holder (18, 31) with a masking element (39) that covers said marks (21-24), said light source (15) illuminates an edge face (34) of said lens (2) so that the light penetrates into a bulk (35) of said lens (2) and reaches said masking element (33) through said lens (2). |
