Epiphora is the medical term for excessive watering of the eye.
It occurs when tears either overproduce due to irritation or do not drain properly through the tear ducts.
People with epiphora often notice constant tearing, blurred vision, or tears running down the cheek.
Blocked tear drainage (nasolacrimal duct obstruction) – tears cannot drain normally
Narrowed tear drainage openings (punctal stenosis)
Eyelid problems – such as ectropion, entropion, or eyelid laxity affecting tear drainage
Dry eye disease – reflex tearing due to surface irritation
Eye irritation or inflammation – from allergies, infection, or environmental factors
Foreign body or eyelash rubbing the eye
Treatment for watery eyes (epiphora) depends on the underlying cause.
Lubricating eye drops may help if watering is due to dry eyes or surface irritation.
Treating eyelid conditions (such as blepharitis, ectropion, or entropion) can improve tear drainage.
Allergy or infection treatment (drops or tablets) may be needed if inflammation is the cause.
Procedures to open or bypass blocked tear ducts may be recommended when tear drainage is obstructed.
An eye specialist will assess the tear drainage system and eye surface to determine the most appropriate treatment.
