  • Patent number: 4240719
    Abstract: An eyeglass lens (ophthalmic lens) has in its upper section (far sight field) surface refraction values relative to far sight, and has in its lower section (near sight field) surface refraction values relative to near sight, and is divided into left and right sections by a line (main meridian), the points of which at least approximate geometric umbilical points (points of the same surface refraction value in the two main curvatures) in which a transition region (progression zone) is provided between the upper section and the lower section, in which the surface refraction values of the upper section change gradually into the surface refraction values of the lower section and in which all the lines of equal average refraction values of the upper section intersect the main meridian in the upper section and all the lines of the lower section intersect the main meridian in the lower section and all are extended on both ends to the periphery of the eyeglass lens.
