Longitudinal Chromatic Aberration of the human eye: psychophysical and reflectometric measurements in an AO system, published in BOE



This study presents the Longitudinal Chromatic Aberration (LCA) of the human eye measured in subjects using wavefront sensing, double-pass retinal images, and psychophysical methods with a custom-developed polychromatic Adaptive Optics system in a wide spectral range (450-950 nm) than previously explored, with control of subjects’ natural aberrations. LCA from reflectometry measurements is consistently lower than from psychophysical. High order aberrations play little role in these differences.
