摘要 |
The disclosure relates to shaped ophthalmic lenses and methods for providing such lenses, including non-powered lenses having non-quadratic surfaces of complementary curvature. Such lenses may have a curvature maximum away from an axis of symmetry and a substantially constant wall thickness. Equations describing and methods of designing such lenses are disclosed including embodiments where two spheres of substantially different curvature are merged in accordance with a weighting function, and adjusted using merit functions.
