Abstract (en)

[origin: FR2890190A1] The method involves superimposing a pupil point of a final contour (3) on a center point (CO) of an uncut ophthalmic lens (1), and relatively adjusting the final contour inside an initial contour (2) of the uncut lens. The final contour adjusting step involves an angular orientation relative to the initial contour with regard to the final contour around the center point according to an angular position of adjustment to reduce the amount by which the final contour exceeds the initial contour of the lens.
