Abstract:
1. A spectacle lens comprising: a front surface; a back surface; a peripheral edge; and a vision correcting area having a refractive error correction that uses ambient light for correcting a refractive error of an eye, wherein at least a portion of the refractive error correction is based on a lens prescription determined by a wave front analysis of a wearer's eye, wherein the vision correcting area corrects non-conventional refractive error to provide at least a part of the wearer's vision correction, wherein the peripheral edge is capable of being modified to fit within an eyeglass frame, wherein the non-conventional refractive error is a refractive error other than myopia, hyperopia, presbyopia or regular astigmatism, and wherein correction of the non-conventional refractive error is provided by localized changes in refractive power of the lens.
