Evaluation of discomfort glare in the 50+ elderly: experimental study.
OBJECTIVES The aim of the study was to analyze discomfort glare sensation in subjects aged 50 years and more in comparison with younger subjects (i.e. younger than 35 years of age). MATERIAL AND METHODS The experiments were performed on a computer workstation placed in controlled lighting environment where 2 discomfort glare conditions were modeled. Each participant performed for about 1 h sp...
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 کاملCortical 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 کاملDynamic Daylight Glare Evaluation
In non-residential buildings, comfort and energy demand for heating, cooling and lighting are significantly influenced by the façade. Up to now, only non-weighted luminance-based methods for calculating and evaluating annual daylight glare exist (Lee et al., 2005; Mardaljevic and Lomas., 1998). Within this paper, different methods based on the daylight glare probability DGP (Wienold and Christo...
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...
