Abstract

The eye suffers from about 2D of longitudinal chromatic aberration (LCA). However, the blur that would be expected to result from this aberration has little effect on visual acuity (VA), largely because the eye’s lower spectral sensitivity at the extremes of the spectrum reduces the effect of the out-of-focus blur associated with the chromatic aberration (Campbell and Gubisch, 1967), although depth-of-focus (DOF) in white light is slightly greater than that in monochromatic light (Campbell, 1957).
