eyeshine
Animal eye glow
Eyeshine is the glow reflected from an animal's eyes when light hits them in darkness—the flash of a cat's eyes in headlights, a deer frozen on a night road.
The effect comes from a reflective layer behind the retina that amplifies low light for nocturnal vision.
Hunters and wildlife watchers use eyeshine to spot animals after dark.
