Eye redness, sometimes called red or bloodshot eyes, occurs when tiny blood vessels on the surface of the eye dilate or become inflamed. This can be a reaction to irritation, fatigue or injury. Redness can affect one or both eyes and develop gradually or suddenly. While many cases are harmless, persistent or painful redness may indicate a more serious problem.
