A dictionary definition describes glare as "difficulty seeing in the presence of bright light such as direct or reflected sunlight, or artificial light such as car headlamps at night", but just to complicate matters, there are different types of glare to consider ranging from mild discomfort to impairment in the ability to see and perform a task.
Discomfort glare from a light source or luminaire, where brightness is greater than the eye can adapt to, makes a task uncomfortable to perform. The degree of discomfort depends on several factors: the brightness and size of the source, its position in relation to the line of sight, and the background luminance.
Disability glare is caused by a reduction of contrast which leads to a decrease in visibility. This type of glare describes the situation when the ability to perform is adversely affected, such as driving when the sun is low or towards a vehicle using full beam headlights.
