1. An ophthalmic spectacle lens comprising:

  • a vision correcting area having a refractive error correction that focuses an image of ambient light on to the retina of an eye for correcting refractive error of the eye, whereinthe vision correcting area'"'"'s refractive error correction is determined at least in part by a wave front analysis of the eye being corrected;

    the refractive error correction corrects at least in part for non-conventional refractive error, wherein the non-conventional refractive error is a refractive error other than myopia, hyperopia, presbyopia and regular astigmatism;

    wherein the refractive error correction is provided at least in part by a plurality of optical property variations of said lens, wherein said optical property variations are variations in the index of refraction of said lens; and

    wherein said lens is capable of being edged into the shape of an eyeglass frame.
