Abstract

A spectacle lens is disclosed. The disclosed lens provides a vision correcting area for the correction of a wearer'"'"'s refractive error. The viewing correction area provides correction for non-conventional refractive error to provide at least a part of the wearer'"'"'s vision correction. The lens has a prescription based on a wave front analysis of the wearer'"'"'s eye and the lens can further be modified to fit within an eyeglass frame.
