Attentional modulation of temporal contrast sensitivity in human vision. [PDF]
Recent psychophysical studies have shown that attention can alter contrast sensitivities for temporally broadband stimuli such as flashed gratings. The present study examined the effect of attention on the contrast sensitivity for temporally narrowband ...

Predictors of vision impairment in Multiple Sclerosis. [PDF]
Visual impairment significantly alters the quality of life of people with Multiple Sclerosis (MS). The objective of this study was to identify predictors (independent variables) of visual outcomes, and to define their relationship with neurological ...

Simulating Visibility and Reading Performance in Low Vision
PurposeLow vision reduces text visibility and causes difficulties in reading. A valid low-vision simulation could be used to evaluate the accessibility of digital text for readers with low vision.

Neural Mechanisms for Drosophila Contrast Vision [PDF]
Spatial contrast, the difference in adjacent luminance values, provides information about objects, textures, and motion and supports diverse visual behaviors. Contrast computation is therefore an essential element of visual processing. The underlying mechanisms, however, are poorly understood.

Vision Rehabilitation is Part of AMD Care
AMD does not just affect the retina. It severely affects people’s lives. Paying attention to this aspect will only become more important as the population ages and more otherwise healthy individuals become affected.

Background chromatic contrast preference in cases with age-related macular degeneration
Objective: To identify background chromatic contrast preferred subjectively by patients with age-related macular degeneration (AMD). Methods: Prospective observational case series. Study subjects with AMD were recruited and compared to a control group of

The effect of serifs and stroke contrast on low vision reading
Purpose: Patients with low vision are generally recommended to use the same fonts as individuals with normal vision. However, we are yet to fully understand whether stroke width and serifs (small ornamentations at stroke endings) can increase readability.

Spatial Contrast Sensitivity to Polarization and Luminance in Octopus
While color vision is achieved by comparison of signals of photoreceptors tuned to different parts of light spectra, polarization vision is achieved by comparison of signals of photoreceptors tuned to different orientations of the electric field ...

A note concerning the relationship between the Adelson’s Argyle illusion and Cornsweet edges [PDF]
Adelson’s Argyle illusion and the Craik-O’Brien-Cornsweet illusion are two noteworthy brightness illusions. In the Argyle illusion two identical gray areas are perceived to have radically different brightness levels when they are surrounded by a
