Influence of age on chromatic aberration of the human eye

We examined the difference in refraction when using portions of the visible spectrum from 437 to 671 nm, and report on the influence of age on the chromatic aberration in one subject 20 years after previous measurements. Changes in refraction were measured with a Rodenstock refractometer which has an exit pupil of 3 mm, and nine narrow band interference filters. Eight subjects were examined under cycloplegia and with dilated pupils. Results confirm previous reports that the magnitude of chromatic aberration decreases with age.
