Term: Mesopic sensitivity

Mesopic sensitivity refers to visual sensitivity under conditions of intermediate light levels, where radiant energy stimulates both the rods and the cones (the two types of retinal photo-receptors). Mesopic vision is a combination of photopic vision (see photopic general) and scotopic vision (see scotopic sensitivity).
