The line of sight connects the fovea with the center of the pupil and is usually tilted in the temporal direction. Thus, off-axis optical aberrations, mainly coma and oblique astigmatism, are introduced at the fovea. Tabernero et al. [J. Opt. Soc. Am. A 24(10), 3274-3283 (2007)] showed that a horizontal tilt of the crystalline lens generates a horizontal coma aberration that is compensated by the oblique light incidence on the eye. Here we suggest that corneal astigmatism may also play a role in compensation of oblique aberrations, and we propose a simple model to analyze such a possibility. A theoretical Kooijman eye model with a slight (~0.6  D) with-the-rule astigmatism is analyzed. Light rays at different incidence angles to the optical axis are considered, and the corresponding point spread functions (PSFs) at the retina are calculated. A quality criterion is used to determine the incidence angle that provides the narrowest and highest PSF energy peak. We show that the best image is obtained for a tilted incidence angle compatible with mean values of the angle kappa. This suggests that angle kappa, lens tilt, and corneal astigmatism may combine to provide a passive compensation mechanism to minimize aberrations on the fovea.<\/jats:p>","DOI":"10.1117\/1.3158996","type":"journal-article","created":{"date-parts":[[2009,7,1]],"date-time":"2009-07-01T18:03:33Z","timestamp":1246471413000},"page":"1-6","source":"Crossref","is-referenced-by-count":11,"title":["Corneal primary aberrations compensation by oblique light incidence"],"prefix":"10.1117","volume":"14","author":[{"given":"Julian","family":"Espinosa","sequence":"first","affiliation":[{"name":"Univ. de Alicante"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Mas","sequence":"additional","affiliation":[{"name":"Univ. de Alicante"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henryk T.","family":"Kasprzak","sequence":"additional","affiliation":[{"name":"Wroclaw Univ. of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"189","reference":[{"key":"10.1117\/1.3158996_r1","doi-asserted-by":"publisher","DOI":"10.1167\/6.1.1"},{"key":"10.1117\/1.3158996_r2","doi-asserted-by":"publisher","DOI":"10.1364\/JOSA.63.000205"},{"key":"10.1117\/1.3158996_r3","doi-asserted-by":"publisher","DOI":"10.1016\/0042-6989(79)90244-X"},{"key":"10.1117\/1.3158996_r4","doi-asserted-by":"publisher","DOI":"10.1364\/OL.23.001713"},{"key":"10.1117\/1.3158996_r5","doi-asserted-by":"publisher","DOI":"10.1167\/1.1.1"},{"key":"10.1117\/1.3158996_r6","doi-asserted-by":"publisher","DOI":"10.1167\/4.4.2"},{"key":"10.1117\/1.3158996_r7","doi-asserted-by":"publisher","DOI":"10.1364\/JOSAA.24.003274"},{"key":"10.1117\/1.3158996_r8","doi-asserted-by":"publisher","DOI":"10.1016\/j.visres.2007.10.016"},{"key":"10.1117\/1.3158996_r9","doi-asserted-by":"publisher","DOI":"10.1080\/09500340210129248"},{"key":"10.1117\/1.3158996_r10","first-page":"14","volume":"60","author":"Satterfield","year":"1981","journal-title":"J.
