Abstract (en)

[origin: FR2910644A1] The device has an acquisition device (53) e.g. camera, for capturing an image set of an extraction opening (110) of an ophthalmic lens (100) along a lighting direction (D51, A52) or capturing an image (A53). A processing system (54) processes the image when the lens is carried by a support (55), and determines a center position of a mouth of the opening from the image set of the opening and/or transversal dimension of the mouth of the opening corresponding to a required transversal dimension, where the mouth emerges on front surface (98) of the lens.
