photoreception

any of the biological responses of organisms to stimulation by light. Most organisms, including humans, respond to visible light; some react to wavelengths of light not seen by humans; and still others can react to properties of light not detectable by humans, such as polarization (vibration of light waves in a definite pattern). This article is concerned with the sensory processes by which animals detect information carried by light.
