Higher-order wavefront correction

With completely custom lens surfaces comes the opportunity to try and address higher order aberrations. The changing gaze angle of the eye during normal vision makes correction difficult in general use. However, researchers have claimed some improvements in vision using aspheric designs. Further, vision is a very active process, wherein eye movements  are undertaken to improve understanding of the current scene. This suggests that the eye might discover and utilize a special high-order correction zone.

FormuLens provides the ability to incorporate various types of high-order corrections in freeform lenses.
