Performance of the human eye is affected by generated aberrations along the optical path of the eye. So that, different the human eye models were designed and studied to understand the philosophy of this issue to treat it. The aim of this work is to study the impact of the iris diameter on the response of the human eye programmatically when white light is applied. The models of perfect and abberated eyes were designed by ZEMAX, PC software (version 15), and the iris diameter was changed from 2-10 mm gradually by 2 under the influence of white light. The modulation transfer function (MTF), wavefront aberration and root mean square of the spot sizes (RMS) were used to analysis the eye response to diameter variation and applied light. The results showed that the ideal image quality obtained at 2 mm iris diameter and started to get worse as the diameter was getting large. The lowest values of aberrations can be achieved by smaller iris diameters. Different types of aberration are generated whenever the iris diameter becomes larger, especially when the white light is applied due to generation of chromatic aberration, which in turn causes the dispersion of light to focus on a small spot on the retina.
