Abstract: We describe a practical approach for modeling and simulating the visual perception of monochromatic images observed by optical systems with low-aberrations (i.e., myopia, hyperopia and astigmatism). It is based on Fourier optics and uses a DSLR camera to validate results of how such aberrations affect vision. We demonstrate its effectiveness by comparing the simulation outcomes against optical ground truth with three objective metrics. In addition to simulation, we present a psychophysical experiment together with an apparatus to estimate the absolute threshold for vision. Preliminary evaluation has shown that our technique produces convincing results.
