Monochromatic aberrations in the accommodated human eye.

摘要: The wave-front aberration of the human eye was measured for eight subjects using a spatially resolved refractometer (a psychophysical ray-tracing test). eyes were undilated and presented with accommodative stimuli varying from 0 to -6 diopters. Monochromatic aberrations tend increase increasing levels accommodation, although there are substantial individual variations in actual change aberration. While spherical always decreased it did not positive negative every observer. direction amount fourth order varied between observers. Aberrations orders higher than at minimum near resting state accommodation. accommodation induced wavefront strongly related total studied.
