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
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
Zernike Polynomials
Truncated expansions such as Zernike polynomials provide a powerful approach for describing wavefront data. However, many simple calculations with data in this form can require significant computational effort. Important examples include recentering, renormalizing, and translating the wavefront data.
