We presented a paper describing some of the core ideas behind our lens design algorithm in San Diego at the SPIE Current Developments in Lens Design and Optical Engineering.
LifeForm Progressive Design
Lenses individually tailored to lifestyle Our LifeForm progressive addition lens design can be viewed as a set of 14 different designs which target different usage priorities (including balanced options, for general use), while still providing full progressive functionality. The ideal
Aspheric Back Surface Designs
For high power single-vision lenses, significant improvement can be achieved with freeform lenses, even with spheric blanks. The following plots describe the performance for a surface optimized for a +13 Diopter prescription with CR-39 and a spheric blank.
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
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
SimPAL
Progressive Lens design is a complex problem. As described in our PAL Anatomy article, there are a large number of lens details to optimize and trade-off. Further, it is not even clear how one can change such structural features to
