Poor Man's Aberrometer - 1.0.1

For some people small letters viewed from a sufficiently large distant have a bit fused shape and may be surrounded by some halos, glares or wings. The reasons of those distortions are so called HOAs (Higher-Order Aberrations), which can slightly modify the human perception. The Poor Man's Aberrometer is a human eye simulator which, by means of strict ray-tracing, shows the HOAs effects on retinal images. The aberrations are highly customized with the use of intuitive controls for scaling and rotating the basic ones, which are generated by 28 Zernike polynomials.
