Watering eyes happen when tears are produced in excess or can't drain away properly, often due to irritation, allergies, a blocked tear duct, or dry eyes triggering a reflex overproduction of tears. It's common in both babies, due to underdeveloped tear ducts, and older adults.
Evidence checked against HSE guidance for watering eyes, covering common causes, treatment options and indications for medical or urgent assessment.
