描述了一种具有前部和眼侧边界表面，以及与这有助于像差的校正的变化的折射率的眼科透镜。 根据本发明的眼镜镜片的特征是等电位面中的至少一个家族（N（X，Y，Z）=常数）具有恒定的折射率，在其表面的所有点处的正常各方向具有相同的距离（平行面），以及或它们的 延伸，其连接所述前表面和眼球侧表面相交的玻璃顶点轴线。

Disclosed is a lens with a front and eye-side boundary surface and with a varying refractive index which contributes to the correction of aberrations. The spectacle lens according to the invention is characterized by at least one family of level surfaces (n (x, y, z) = const.) With a constant refractive index, which in all respects each same distance in the direction of its surface normal (parallel surfaces), and the or their extension of the axis which connects the glass vertices of the front surface and the eye-side surface intersect.
