Red eye (single)
Red eye is a symptom in which a one or both of a person's eyes are redder than normal. Redness is usually caused by increased blood (red colored) in the reddened area. Increased blood flow can be due to allergies, inflammation, infection, hormonal changes, nerve problems, drug side effects, etc.
