(glār) [Middle English glaren] a condition of discomfort in the eye and of depression of central vision produced when a bright light enters the field of vision, especially when the eye is adapted to dark. The amount of glare is directly proportional to the candle power of the light and inversely proportional to the square of the distance of the light from the eye and to its angular distance from the visual axis.
