Abstract
15 págs.; 7 figs.; 1 tab.; OCIS codes: (260.0260) Physical optics; (330.0330) Vision, color, and visual optics; (330.4875) Optics of physiological systems; (330.5370) Physiological optics; (220.1010) Aberrations (global); (220.1080) Active or adaptive optics.© 2015 Optical Society of America. Longitudinal Chromatic Aberration (LCA) influences the optical quality of the eye. However, the reported LCA varies across studies, likely associated to differences in the measurement techniques. We present LCA 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), with control of subjects’ natural aberrations. LCA measured psychophysically was significantly higher than that from reflectometric techniques (1.51 D vs 1.00 D in the 488-700 nm range). Ours results indicate that the presence of natural aberrations is not the cause for the discrepancies across techniques.This research has received funding from the European Research Council under the European Union’s Seventh Framework Program (FP/2007-2013) / ERC Grant Agreement. [ERC-2011- AdC 294099]. This study was also supported by Spanish Government grant FIS2011-25637 to SM, CSIC JAE-Pre programs & MICINN FPU Predoctoral Fellowship to MV, and CSIC JAE-Tec program to DC.Peer Reviewe
