Abstract

In a spectacle lens, one surface has at least one area with an approximately constant power, except for aspheric corrections, and at least one transition area with a progressively increasing or diminishing power adjacent to the area with an approximately constant power. The other surface of the lens has an astigmatic effect. The orientation of the surface with astigmatic effect with respect to the surface with progressive power depends on the position of the axis of astigmatism of the eye. This spectacle lens is characterised in that the surface with astigmatic effect has at least one main section whose form differs from the toric form, in a per se known manner, and in that the surface with astigmatic effect is a surface optimised for an axis located at 0 DEG , independently of the orientation of said surface with respect to the surface with progressive power.
