Distant Distortion viewed

Poor Man's Aberrometer Description

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 Mans Aberrometer is a human eye simulator which, by means of strict ray-tracing, shows the HOAs effects on retinal images.• Designed for Mac OSX 10.4 and above.• 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.• The aberrations are depicted as a height map over a retina, resembling pre-LASIC inquiry aberrometer plots.• The target image presented to the artificial eye can be edited using a simple editor.• The aberrations are stored on documents with any number of images to allow you explore the effects of each aberration.• The retinal images are filtered to mimic the human perception.• You can export the aberration map, the target image and the retinal image as tiff images.
