Contrast detection thresholds are elevated with optical quality loss in keratoconus. This
study hypothesized that suprathreshold contrast perception is also impaired in keratoconus …

Abstract Purpose/Background This study examined the effect of myopic defocus on visual
acuity (VA) over time, with attention being paid to the first point at which blur adaptation had …

It is sometimes claimed that because the resolution and sensitivity of visual perception are
better in the fovea than in the periphery, peripheral vision cannot support the same kinds of …

purpose. To determine whether blur adaptation influences blur sensitivity and blur
discrimination thresholds in young adult myopes and emmetropes. In addition, to determine …

Simultaneous vision is an increasingly used solution for the correction of presbyopia (the
age-related loss of ability to focus near images). Simultaneous Vision corrections, normally …

Certain visual stimuli, such as striped patterns and filtered noise, have been reported to be
uncomfortable. Some filtered noise patterns judged as uncomfortable are those with a …

The growth of the eye, unlike other parts of the body, is not ballistic. It is guided by visual
feedback with the eventual aim being optimal focus of the retinal image or emmetropization …

Perceptual learning produces an improvement in visual functions such as an increase in
visual acuity (VA) and contrast sensitivity in participants with both amblyopia and refractive …

In the context of this book, adaptation is taken to mean a feature of a system aimed at
achieving the best possible performance, when mathematical models of the environment …

The visual system is said to be especially sensitive towards spatial but lesser so towards
temporal information. To test this, in two experiments, we systematically reduced the acuity …
