Abstract

An ophthalmic spectacle lens comprises a front surface; a back surface; a peripheral edge; and a vision correcting area having a refractive error correction for correcting refractive error of the eye, wherein the vision correcting area's refractive error correction is determined at least in part by a wave front analysis of the eye being corrected. Additionally, the refractive error correction corrects for non-conventional refractive error, wherein the non-conventional refractive error is a refractive error other than myopia, hyperopia, presbyopia and regular astigmatism, wherein said lens is capable of being edged into the shape of an eyeglass frame.
