Rotationally symmetrical aspheric surfaces of spectacle lenses are constructed as either “zonal aspherics” or “continuous aspherics.” Zonal aspherics consist of annular zones …

One of the criteria in ophthalmic spectacle lens design is the elimination of oblique astigmatism. For a range of equivalent powers, Seidel (primary or third-order) astigmatism …

The task of designing an ophthalmic corrective lens is one of optimizing a system by modifying only a fixed front element with remainder of the system rotatable about the stop …

Merté (1950) described lens forms that correct oblique astigmatism at all ocular rotations. The front surfaces of all lenses were flat, and the back surfaces were made aspherical as …

It is shown that, in general for a rotationally symmetric surface, the sagittal curvature is a function of the first derivative and tangential curvature is a function of the first and second …

The significant aberrations in ophthalmic lenses are (oblique) astigmatism (spectacle lenses) and spherical aberration (contact and intra-ocular lenses). In many cases, they …
