Abstract
A method of designing lenses includes defining a material having an inside reflective surface spanning an area, and providing an optical design algorithm which defines a plurality of oxels across the area. Each oxel has a plurality of sub-elements including a center sub-element and a plurality of neighboring sub-elements. Based on a defined optical prescription for the inside reflective surface, an optically corrected reference 3D surface is calculated for each oxel having spherical and cylindrical corrections relative to a spherical contour which spans a predetermined field of view (FOV) with respect to a single (common) predetermined reference point. A position of at least a first of the sub-elements for each of the oxels is moved to approach respective final 3D positions on the optically corrected reference 3D surface, where the moving is constrained to be along an individual line connecting each of the first sub-elements to the single predetermined reference point.
