Background The image formed by the eye's optics is inherently blurred by aberrations
specific to an individual's eyes. We examined how visual coding is adapted to the optical …

Variations in blur are present in retinal images of scenes containing objects at multiple depth
planes. Here we examine whether neural representations of image blur can be recalibrated …

Blur is an intrinsic feature of retinal images that varies widely across images and observers,
yet the world still typically appears' in focus'. Here we examine the putative role of neural …

Background The 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 …

Background. Although blur discrimination in the foveal region has been investigated,
knowledge regarding the effect of retinal eccentricity is limited. Methods. The initial blur …

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 …

The perceived focus of an image can be strongly biased by prior adaptation to a blurred or
sharpened image. We examined whether these adaptation effects can occur for the natural …

Theimage formed by the eye's optics is inherently blurred by aberrations specific to the
individual's eyes. We examined to what extent judgments of perceived focus depend on the …

Purpose: The purpose of this study was to evaluate retinal responses to different types and
magnitudes of simulated optical blur presented at specific retinal eccentricities using …

Knowledge regarding successive blur discrimination thresholds (ie, equiblur zones) in depth
and across the near retinal periphery, and their relation to blur detection (ie, depth-of-focus) …
