Abstract
Multifocal and single focus lenses are defined by nonconical aspheric optical surfaces. Various alternative surface shapes provide one or more vision regions bounded by optical steps. Each optical step has rapidly and smoothly changing power in the radial direction which creates an induced aperture through which the cortical elements of the human vision system are induced to concentrate. The induced aperture results in increased clarity and enhanced vision. In various configurations, the induced aperture decreases spherical aberration to further enhance vision. To increase correction intensity at one or more powers, redundant power regions are provided in repeated optical steps or annular apertures. In several embodiments, the redundant power regions create multiple induced apertures at one or more optical powers directed at one or more vision distances.
