Wavefront Aberrations and the Image Quality of the Eye

The optical performance of the human eye is not ideal: it has long been recognized that it is diffraction limited only for relatively small pupil diameters. For larger diameter pupils the aberrations of the eye’s optics come into play, limiting visual acuity and contrast sensitivity. With the development of new surgical techniques for correcting the optics of the eye, there has been a renewed interest in developing accurate, reproducible techniques for measuring the wave-front aberrations of the human eye as well as for studying changes in the optics of the eye with age.  We have been using a rapid psychophysical technique (ref 2 below) to measure the optical performance of the human eye.   Using this we have quantitatively investigated the change in optical image quality of the eye with accommodation, aging and wavelength.  Wavelength especially is a major factor that will limit the achievable improvement in the eyes optics for natural stimuli.
