Why do our eyes turn red in flash photos?

When an animal’s eyes glow green or yellow in the headlights, it’s a sign of good night vision. A special layer of cells in the back of the eye reflects light back like a mirror. Some of that light is reabsorbed by the eye, letting a deer, raccoon, or opossum see better in the dark. But human eye-glow doesn’t lead to anything but weird-looking birthday photos—Mom, Dad, and little Billy leaning over the candle-studded cake, all with gleaming red eyes. If a camera steals your soul, perhaps a flashbulb replaces it with something demonic.
