Abstract
Aberration-induced vision symptoms are determined by obtaining at least one wave aberration of an eye, calculating at least one point-spread function from the wave aberration, convolving the point-spread function of eye with at least one specially designed image for night vision diagnosis, and determining at least one aberration-induced vision symptom of the tested eye from the convolved images. The specially designed images are for vision diagnosis of aberration-induced glare, halo, ghost image, and starburst. The invention methods for specifying aberration-induced symptoms allow to find an optimized refractive corrections of defocus and astigmatism and to reduce vision symptoms caused by aberrations in the eye.
