    Abstract: A method for determining a progressive ophthalmic lens comprising a near and a far vision area, a main meridian separating the lens into a nasal and a temporal area, the method comprising: determining a first and a second surface of the lens; determining the second surface to provide, in combination with the first surface, the vision correcting properties; determining a spherical area on the first surface of the lens having a constant sphere value and including a far vision diopter measurement position, wherein the far and a near vision diopter measurement position have substantially the same mean sphere value; and determining the first surface to reduce the lens distortion by defining a toric area extending outside the spherical area on the first surface in at least one of the nasal and the temporal area, wherein characteristics of the toric area are related to the lens astigmatism.

    Abstract translation: 一种用于确定渐进眼镜片的方法，所述渐进眼镜片包括近视区和远视区，将所述镜片分隔成鼻和颞区的主子午线，所述方法包括：确定所述镜片的第一和第二表面; 确定第二表面以结合第一表面提供视力校正特性; 确定具有恒定球面值并且包括远视度数测量位置的透镜的第一表面上的球面积，其中远视近屈光度测量位置和近视觉屈光度测量位置具有基本上相同的平均球面值; 以及通过在所述鼻区域和所述颞区域中的至少一个区域中限定在所述第一表面上延伸到所述球形区域之外的复曲面区域来确定所述第一表面以减小所述镜片失真，其中所述复曲面区域的特征与所述镜片散光有关。

    Abstract: Ophthalmic lens having a first surface comprising a zone of optical interest, the zone of optical interest comprising at least: - a far vision control point (FV), - a near vision control point (NV), - a main line (M) starting from one end of the zone of optical interest, ending on the opposite end of the zone of optical interest and passing through the far and near vision control points, wherein the main line (M) comprises at one end a first section (S1) of continuous increase of mean sphere, at the other end a second section (S2) of continuous increase of mean sphere, the first and second section being separated by a third section (S3) of stabilized mean sphere.
