摘要： An ophthalmic lens in which one surface is provided with at least one region, in which the refracting power is practically constant except for aspherical corrections, and at least one transition region which is adjacent to the region having practically constant surface refracting power, and in which the surface refracting power increases or decreases continuously, and the other surface is provided with an astigmatic effect. The orientation of the surface having an astigmatic effect relative to the surface having continuous refracting power change is dependent on the position of the axis of the astigmatism of the eye. The surface having an astigmatic effect deviates from the toric shape and is independent of the orientation of the surface relative to the surface having continuous refracting power change which is a surface optimized for the axial position of 0.degree..

摘要： An ophthalmic lens having a front and an eye-facing boundary surface and a varying refractive index, which contributes to the correction of aberrations. The ophthalmic lens is distinguished by having at least one system of surfaces at given level (n(x,y,z)=const.) with a constant refractive index, which are spaced the same distance at all points in the direction of their surface normals (parallel surfaces), and which, respectively their extension, intersect the axis connecting the lens apexes of the front surface and the eye-facing surface.
