Using Pattern Classification to Measure Adaptation to the Orientation of High Order Aberrations

Published on 2013-08-14 in PLoS ONE, vol 8. DOI: 10.1371/journal.pone.0070856
BackgroundThe image formed by the eye's optics is blurred by the ocular aberrations, specific to each eye. Recent studies demonstrated that the eye is adapted to the level of blur produced by the high order aberrations (HOA). We examined whether visual coding is also adapted to the orientation of the natural HOA of the eye.Methods and FindingsJudgments of perceived blur were measured in 5 subjects in a psychophysical procedure inspired by the “Classification Images” technique. Subjects… Read more
