System and method for optical reading of markings printed on a face of an ophthalmic lens

摘要

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.
