Scotopic Vision (Overview)

Scotopic vision is "night vision", in which the eyes use light receptors called "rods". Rods are in the retina, are sensitive to very low light, and do not see in color. The daylight receptors called "cones" see in color and are used in normal to bright light conditions. At night, both rods and cones are used together in typical city neighborhoods lit by street lighting, signs, automobile lights, etc.
