What causes my eyes to get red?

ANSWER

Your eyes get red when the tiny blood vessels on the surface of the eyes expand and turn the whites of one or both eyes a pink or reddish tint. Many things can cause it, like a night of heavy drinking, or a physical injury to your eye. But if you haven’t had too much alcohol, or scratched or poked your eyeball recently, there are other possibilities, including:

  • Allergies
  • Dry eyes
  • Pinkeye
  • Broken vessel
  • Glaucoma
