The main reasons your eyes keep watering are either overproduction of tears or poor tear drainage. Overproduction of tears often happens as a reflex to eye irritation or dryness, where the eye produces extra tears to lubricate and protect itself. Common causes include dry eye syndrome, allergies, eyelid problems (like inflammation or eyelash issues), exposure to wind, cold, or bright light, and eye irritation from foreign bodies or chemicals. Poor tear drainage can occur if your tear ducts are blocked, narrow, or if the eyelids are sagging or turning inward or outward, preventing tears from draining normally. Other possible causes include infections like conjunctivitis, blocked tear ducts especially in babies, and certain medications. Temporary watering can also be triggered by emotions, yawning, or reactions to strong tastes. Persistent watering should be checked by a healthcare professional for proper diagnosis and treatment, which may include lubricating drops, addressing allergies or infections, or possibly surgery if tear drainage is blocked. In sum, watery eyes happen because your eyes produce too many tears or the tears don't drain properly, often due to irritation, dryness, allergies, eyelid issues, or tear duct problems.
