1. An ophthalmic lens, comprising:
- a. a first optical power region;
b. a second optical power region;
c. a third optical power region located on a surface of said lens between said first optical power region and said second optical power region, wherein said third optical power region has changing optical power and a progressive surface topography; and
d. a layer of a varying index of refraction.

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.
