Why do NFL players wear eye black?
Show answer & explanation
Answer: Reduces sun glare reflection
Reduces sun glare reflection ✓ — Correct! Eye black works by reducing glare. The dark grease or sticker under the eyes absorbs light instead of letting the skin reflect it up into the eyes, so bright sun or stadium lights are less distracting. Studies show the effect is modest but real, and players in baseball and football have used it for that reason. Some of the benefit may come from tradition or placebo, but the anti-glare purpose is the main one.
Protects skin from cold — Wrong. Eye black does not insulate or warm the skin. It is a dark, non-reflective coating that cuts glare by absorbing light on the cheekbones, keeping it from bouncing into the eyes.
Tradition from early football — Wrong. Tradition is part of the story, but the practice started for a functional reason: cutting the light that reflects off the cheeks and interferes with vision in bright conditions.
