Cortical hyperexcitability and sensitivity to discomfort glare
It is well established that there are two main aspects to glare, the visual impairment and the discomfort, known as disability and discomfort glare, respectively. In contrast to the case of disability glare we understand very little about the underlying mechanisms or physiology of discomfort glare. This study attempts to elucidate the neural mechanisms involved using fMRI and glare sources with...
متن کاملWorkshop on Discomfort Glare: Final Report
Limitations to the predominant models for discomfort glare prediction for electric lighting, the Unified Glare Rating and the Visual Comfort Probability, are well known. There is no single widely-accepted model as yet for discomfort experienced from daylight. Overhead glare from small, bright light sources is a newlyidentified problem. This workshop at the CIE Session in Sun City sought to anim...
متن کاملMechanisms for discomfort glare in central vision.
PURPOSE The presence of a bright light source in the visual field can generate visual discomfort. Based on empirical observations we can predict to a reasonable degree of accuracy how uncomfortable a given lighting installation is likely to be; yet very little is known about the mechanism or physiological underpinnings that lead to visual discomfort. This study attempts to elucidate some of the...
متن کاملMacular pigment and visual performance in glare: benefits for photostress recovery, disability glare, and visual discomfort.
PURPOSE One theory of macular pigment's (MP) presence in the fovea is to improve visual performance in glare. This study sought to determine the effect of MP level on three aspects of visual performance in glare: photostress recovery, disability glare, and visual discomfort. METHODS Twenty-six subjects participated in the study. Spatial profiles of MP optical density were assessed with hetero...
متن کاملEye movement and pupil size constriction under discomfort glare.
PURPOSE Involuntary physiological responses offer an alternative means to psychophysical procedures for objectively evaluating discomfort glare. This study examined eye movement and pupil size responses to glare discomfort using new approaches to analysis: relative pupil size and speed of eye movement. METHODS Participants evaluated glare discomfort using the standard de Boer rating scale und...
