Prediction of discomfort glare from windows

Lighting Research & Technology, 2003
Visual discomfort in a day-lit interior environment is usually represented by the degree of discomfort glare perceived by the user. The paper reports on the evaluation of several models for the prediction of discomfort glare from daylighting, using data collected over a 10-month period, in a purpose built test cell.

Discomfort Glare in Lighted Streets

Transactions of the Illuminating Engineering Society, 1940
Glare which affects comfort or causes distraction is distinguished from glare which affects the ability to see. The results of an investigation to determine the factors which cause discomfort glare in lighted streets are summarised, and the influence of these factors on problems of street lighting design is studied.

Discomfort glare from interesting images

Lighting Research & Technology, 2005
In laboratory experiments, subjects viewed bright images projected on to small screens. The projected images ranged from neutral patterns to complex scenes. There was a greater tolerance of discomfort glare from images previously judged ‘interesting’ by an independent subject group than from other screen images giving the same calculated glare rating ...

Discomfort Glare from Automobile Headlights

Journal of the Illuminating Engineering Society, 1984
Three studies are described concerning discomfort glare arising from automotive headlamps. Two issues were of principle concern, (1) the so-called “range effect,” and (2) the relationship between laboratory and field findings concerning glare. The first study was conducted in a laboratory and was designed to evaluate the range effect and subject age. A

The demographic variables of discomfort glare

Lighting Design + Application, 1977
Are older people more sensitive to discomfort from overly bright lighting systems than young people? The answer is yes. The average population is more sensitive in direct proportion to their age from below the 20's to the 70's. Also, blue-eyed people are more sensitive than brown-eyed, and indoor workers have greater sensitivity than-outdoor workers ...

INFLUENCE OF PHYSIOLOGICAL FACTORS ON DISCOMFORT GLARE LEVEL

American journal of optometry and archives of American Academy of Optometry, 1969
ABSTRACT Each of a group of observers adjusted the intensity of a sun‐sized source to his borderline between visual comfort and discomfort (BCD). The measured BCD intensity of each observer was compared with many of his physiological and visual characteristics.

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.
