<p>The method involves setting a material of a lens element and another material of another lens element, where a transition point (40) is determined between a base area and an achromatic lens on a rear surface of a spectacle lens. A cross-sectional plane of the spectacle lens runs through the transition point. A V-edge angle (62) is determined between the rear surface of the latter element and a front surface (34) of the latter lens element at the transition point in the cross-sectional plane. An independent claim is included for a pair of spectacles with a frame.</p> |
