Abstract—Human eyes are not perfect optical systems, most
of them have refractive errors, the simulation of which is a plus
to the realistic vision rendering. This paper presents the
simulation of the properties of human eye optical system with
an abstracted human eye optical model, including myopia,
hyperopia and astigmatism. A novel and effective
ray-tracing-based method is brought out in this paper, which
calculates the direction of rays refracted by the eye without
modeling the surface of the crystalline lens. In order to achieve
better simulation results, a circinate-patterned sampling
method is proposed, which covers most of the radiation angles
and has a distribution similar to Gaussian distribution. The
variation of depth of field accompanied by the adjustment of the
pupil size in reaction to the luminance of the environment is also
simulated.
Index Terms—Ray tracing, myopia, hyperopia, astigmatism,
