For the BoW condition, VA increased with background luminance in both natural and AO-corrected conditions, and there was a benefit of AO correction at all luminances (by a factor of 1.29 on average across luminances). For WoB VA increased with foreground luminance but decreased for the highest luminances. In this reversed polarity condition AO correction increased VA by a factor of 1.13 on average and did not produce a visual benefit at high luminances. The improvement of VA (averaged across conditions) was significantly correlated (p = 0.04) with the amount of corrected aberrations (in terms of Strehl ratio). The improved performance with WoB targets with respect to BoW targets is decreased when correcting aberrations, suggesting a role of ocular aberrations in the differences in visual performance between contrast polarities.MEyC FIS2005-04382, MCeI FIS 2008-02065, and EURYI award to SM; MEyC FPI Predoctoral Fellowship to LS; CSIC I3P Predoctoral Fellowship to EG.Peer reviewedAssociation for Research in Vision and Ophthalmology200820082008info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_65011326391 bytesapplication/pdfhttp://hdl.handle.net/10261/8559reponame:DIGITAL.CSIC.
