Visual comfort probability

Visual comfort probability (VCP), also known as Guth visual comfort probability, is a metric used to rate lighting scenes.

VCP is defined as the percentage of people that will find a certain scene (viewpoint and direction) comfortable with regard to visual glare. ¹² It was defined by Sylvester K. Guth in 1963. ³⁴
