Numerous methods for measuring direct discomfort glare have been proposed over the years. Despite many decades of research, the phenomenon and exact causes of discomfort glare still aren’t fully understood. Discomfort glare is measured and evaluated exclusively on the individual level. Discomfort glare is also referred to as “psychological glare,” as physiological tests can’t measure it and physiological values can’t account for it. Inside a building, bright sunlight entering through a window can cause disability glare.ĭiscomfort glare, on the other hand, occurs when people don’t feel comfortable with their given lighting conditions (because, again, the light source might be too bright), yet don’t find their vision actually impaired. A typical example of high-level disability glare is when, driving on the highway at night, you’re dangerously blinded by the bright headlights of the car coming at you from the opposite direction. When brightness has such an effect on us, it’s subjecting us to disability glare.
