渐进式眼镜镜片具有两个非球面渐进表面

Progressive spectacle lens having two aspherical progressive surfaces
摘要：
A progressive spectacle lens having two aspherical and in particular progressive surfaces, i.e. surfaces contributing to the rise in the effect (addition Add.) from the distance vision portion to the near vision portion, in which the sagittal heights zi=zi(x,y)of at least one (i) progressive surface (i=1,2) are chosen such that the sagittal height z of this respective surface at the edge of the spectacle lens given by yi=fi1(x) for y≧0 and yi=fi2(x) for y
