Graded ophthalmic lens with variable refractive index and method for design and manufacture thereof

Progressive ophthalmic lenses with variable refractive index and methods for the design and manufacture thereof. The invention relates to a progressive ophthalmic lens, the progressive ophthalmic lens having a front side and a rear side and a spatially varying refractive index, the front side and/or the rear side being formed as a free-form surface. The invention is characterized in that the refractive index varies only in the first and second spatial dimensions and is constant in the third spatial dimension, the distribution of the refractive index in the first and second spatial dimensions having neither point symmetry nor axial symmetry, or the refractive index varies in the first, second and third spatial dimensions, the distribution of the refractive index in the first and second spatial dimensions having neither point symmetry nor axial symmetry. Wherein in all planes perpendicular to the third spatial dimension, the distribution of the refractive index in the first and second spatial dimensions has nei
