Título: | Longitudinal chromatic aberration of the human eye in the visible and near infrared from wavefront sensing, double-pass and psychophysics |
Autor: | Viñas, María CSIC ORCID; Dorronsoro, Carlos CSIC ORCID; Cortés, Daniel CSIC; Pascual, Daniel CSIC ORCID; Marcos, Susana CSIC ORCID | Fecha de publicación: | 24-feb-2015 | Editor: | Optical Society of America | Citación: | Biomedical Optics Express 6: 948- 962 (2015) | Resumen: | © 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. | Descripción: | 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. | Versión del editor: | http://dx.doi.org/10.1364/OE.23.00948 | URI: | http://hdl.handle.net/10261/130708 | DOI: | 10.1364/OE.23.00948 | Identificadores: | doi: 10.1364/OE.23.00948 issn: 2156-7085 |
