chromatic aberration
chromatic aberration Chromatic aberration is an optical defect of the eye caused by different colours of light being bent by different amounts, so shorter-wave rays such as violet come to a focus differently from longer-wave rays such as red.
Chromatic aberration is an optical defect of the eye caused by different colours of light being bent by different amounts, so shorter-wave rays such as violet come to a focus differently from longer-wave rays such as red. This can produce coloured fringes at edges under certain viewing conditions, although the effect is usually masked when the eye is focused for the middle parts of the spectrum.
