The Pupillary Response and Discomfort Glare

Journal of the Illuminating Engineering Society, 1975
This IERI report is a four-part study on pupillary fluctuations as an index of discomfort glare. Light reduces the size of the pupil, but it is not size alone that generates discomfort. Rather, it is the fluctuation in size. Here, the authors present new studies of the role of the iris in generating what is known as discomfort glare.

Unified Glare Rating (UGR) and subjective appraisal of discomfort glare

Lighting Research and Technology, 1996
The study investigated the correlation between the subjective glare rating and the Unified Glare Rating (UGR). Experiments and analyses were carried out. The results showed that there was a good correlation between the subjective glare rating and the UGR glare indices, but that the subjective glare ratings were always a few units lower than the UGR ...

Discomfort glare model for mobile display

2015 IEEE 5th International Conference on Consumer Electronics - Berlin (ICCE-Berlin), 2015
This study proposed a new glare model for mobile display according to contents in low illumination condition. The proposed glare model is considered by stimulus size, contrast ratio, stimulus position, averaging luminance, viewing angle, and the number of stimuli. For the model, two-step subjective experiment was conducted.

Discomfort caused by wide-source glare

Energy and Buildings, 1990
Abstract We report here on experiments to measure subjective response to intense light, or glare caused by a wide source. We have investigated three glare indices: the Building Research Station glare index; the CIE glare index and the Cornell daylight glare index. We have also examined the glare vote and have proposed a new glare evaluation scale, as

A portable discomfort glare evaluator

Lighting Research & Technology, 1980
An inexpensive portable instrument is described for the paired comparison observation of direct discomfort glare in interior lighting installations. It is useful for field tests where it complements glare assessment by verbal statements.

Spectral sensitivity for extrafoveal discomfort glare

Journal of Modern Optics, 2009
Previously published evidence suggests that the discomfort glare response to bright lights has greater short-wavelength spectral sensitivity than implied by the photopic luminous efficiency function, V(λ). The present paper summarizes a series of experiments to characterize spectral sensitivity for discomfort glare from nearly monochromatic light ...

An Experiment of Discomfort Glare from Non-uniform Glare Source

Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, 2009
Impact of daylighting on the visual environment can improve occupant`s well-being by providing visual comfort. Also, daylighting can save energy. However, glare from window can be a direct hazard to vision and can cause serious discomfort. Selecting glare source on a window plane is very important for evaluating discomfort glare from windows.
