Their eyes glow because of a layer called the tapetum lucidum just behind the retina. Cats, dogs, deer, and other nocturnal animals have good night vision because whatever the photo-receptor cells in their retina doesn't catch, hits the tapetum lucidum and takes a second pass at the retina again.

How high up can deer see?

The trade-off is that researchers surmise deer can see UV light — something humans can't detect. By studying the physical characteristics of deer eyes, scientists estimate deer have 20/100 vision. This means that the level of detail whitetails see at 20 feet is what normal human vision can see back to 100 feet.
