The device includes receiver elements ( 121, 114 ) for receiving the ophthalmic lens; on either side of the receiver elements, firstly lighting elements (S) for illuminating the ophthalmic lens ( 103 ) installed on the receiver elements, and secondly acquisition elements ( 122, 125 , C) for acquiring the shadow of the ophthalmic lens illuminated by the lighting elements (S); measurement elements (S, 124 , C) suitable for measuring the optical deflection power exerted by the ophthalmic lens on at least one light ray and for delivering a signal representative of the deflection power; and an electronic and computer system including geometrical correction calculation instructions for deducing from the measured deflection power a corrected shape for at least a portion of the shadow of the ophthalmic lens as perceived by the acquisition elements ( 122, 125 , C).
