The Effect of Monocularly and Binocularly Induced Astigmatic Blur on Depth Discrimination Is Orientation Dependent

Abstract

The lesser effect of WTR compared with ATR astigmatic blur on depth discrimination may reflect the contribution of horizontal compared with nonhorizontal disparity processing in stereopsis. The pronounced effect of oblique astigmatic blur may be because of the effects on horizontal and nonhorizontal disparity and interocular differential image blur.
