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.

 

 

 

Custom Generic Progressive Lens

The FormuLens Custom Generic PAL (Progressive Addition Lens) is a single product which can be adjusted through a wide range of performance requirements. With adjustable fitting heights from 12 to 22 mm, and “hardness” ranging between the extremes offered by designs from major vendors, and everything in between. The design is optimized computationally using our lens design system SimPAL for a dense grid of setting combinations.

SimuLens

SimuLens performs a realistic simulation of a spectacle lens in use. The lens is to be described by arbitrary sets of points describing the front and back surfaces (e.g. generator points-files), and a refractive index. The eye position relative to the points is computed based on fitting parameters.
