    • The invention relates to a spectacle lens whose power is adapted in a first viewing zone for seeing into the distance when the glasses are being used; and whose power is adapted in a second viewing zone for seeing into average distances i.e. distances of one metre or more when said glasses are being used. The power of the lens increases in a continuous manner from the first viewing zone to the second viewing zone in a straight or winding main line. The inventive spectacle lens comprises the following characteristics; the power thereof not only increases in a continuous manner from the first viewing zone to the second viewing zone but also beyond the second viewing zone as far as the lower edge of the lens; the clearer viewing zone i.e. the zone wherein the remaining astigmatism of the lens/eye system does not exceed 0.5 dpt, becomes narrower in a funnel-like manner, i.e. without contraction, below the first viewing zone towards the lower edge of the spectacle lens.
    • 本发明提供一种透镜,其适合用于在使用位置的第一观看区域中的远用度数看到的值; 并在看到一个在视线距离的第二观看区域,即 具有用于约一米,并且在使用的位置更合适的折射光焦度的的距离; 并且其中折射率连续从沿平面或绕组Hauptliniezu第二观看区域中的第一观看区域增加。 本发明的透镜具有折射率以下特点并不只从所述第一观看区域到第二观看区域,而且还经由所述第二观看区域,并且直到连续的透镜的下边缘; 清晰视野的区域,也就是说, 其中系统眼镜镜片/眼睛的残余散光不超过0.5 DPT的区域,缩小第一观看区域的眼镜镜片的下边缘的下方的漏斗形状,即 无收缩。
