Red eyes

Red eyes, also known as bloodshot eyes, occur when the tiny blood vessels on the surface of the eye become enlarged or inflamed, leading to a reddish appearance. This can result from various causes such as fatigue, allergies, irritation from contacts or environmental factors, infections like conjunctivitis, or underlying eye conditions. While often harmless and temporary, persistent or severe redness may indicate a more serious issue requiring medical attention. Treating red eyes depends on the cause, ranging from rest and lubricating drops to medications or professional eye care.
