Recognition acuity—the minimum size of a high-contrast object that allows us to recognize it—
is limited by optical and neural elements of the eye and by processing within the visual …

We determined whether distracting the observer's attention from an adapting stimulus could
decrease the motion after-effect. Unlike previous studies we used a relatively bias-free 2AFC …

The visual system can adapt to optical blur, whereby the adapted image is perceived as
sharp. Here we show that adaptation reduces blur-induced biases in shape perception, with …

Purpose: To determine whether changes in wavefront spherical curvature (optical vergence)
are a directional cue for accommodation. Methods: Nine subjects participated in this …

Adaptation to a blurred image causes a physically focused image to appear too sharp, and
shifts the point of subjective focus toward the adapting blur, consistent with a renormalization …

Purpose: The accommodation response has recently been shown to improve visual acuity
(VA) in the presence of astigmatism in some individuals. This improvement could potentially …

Purpose. Adaptation to defocus is known to influence the subjective sensitivity to blur in both
emmetropes and myopes. Blur is a major contributing factor in the closed-loop dynamic …

When repeatedly exposed to moving stimuli, the oculomotor system elicits anticipatory
smooth pursuit (ASP) eye movements, even before the stimulus moves. ASP is affected …

The perception of image focus can be strongly affected by prior adaptation to blurry or
sharpened images or by simultaneous contrast from blurred or sharpened surrounds …

The aim of this study was to determine whether dynamic accommodation responds to
isolated blur cues without feedback, and without changes in the distance of the object. Nine …
