Your watery eyes, or epiphora, are not always caused by a blocked tear duct. Dry eye, irritation, allergies, eyelid problems and inflammation can also make your eyes water.<\/p>\n

Your treatment depends on the cause. Once your eye specialist identifies the problem, you may need dry-eye treatment, eyelid treatment or management of your tear drainage system.<\/p>\n

What Is Epiphora?<\/h2>\n

Epiphora means your eyes are watering more than usual. It is a symptom rather than a specific condition and can happen because of excess tear production or poor tear drainage.<\/p>\n

Your tears normally spread across the surface of your eye with each blink before draining through the lacrimal system. If this balance is disturbed, tears can overflow onto your cheeks, but this does not always mean your tear duct is blocked.<\/p>\n

How Does Your Tear Drainage System Work?<\/h2>\n

Your tears drain through tiny openings called puncta near the inner corners of your eyelids. They then pass through the canaliculi into the lacrimal sac and down the nasolacrimal duct into your nose.<\/p>\n

Your puncta, drainage channels and eyelids all help move tears away from your eyes. A problem anywhere along this pathway can lead to persistent watering.<\/p>\n

Is a Blocked Tear Duct the Most Common Cause in Adults?<\/h2>\n

A blocked or narrowed tear duct is a common cause of persistent watering in adults. Reduced drainage allows tears to build up and overflow, and you may also notice discharge or swelling near your nose. However, watery eyes can also result from dry eye, eyelid problems, allergy, irritation or other causes.<\/strong><\/p>\n

Your watering is not always caused by a blockage, so your eye specialist may need to check for other possible causes before deciding on treatment.<\/p>\n

Can Dry Eye Cause Watery Eyes?<\/h2>\n

Dry eye can cause excessive watering because irritation may trigger reflex tears. These tears can overflow before they properly lubricate and stabilise your eye.<\/p>\n

Your symptoms may also include grittiness, burning, irritation or fluctuating vision. If dry eye is causing your watering, treating the underlying surface problem is important.<\/p>\n

Evidence Note<\/strong><\/p>\n

Research shows that dry eye can be an important cause of watery eyes because irritation of an unstable tear film can trigger reflex tear production. These extra tears may overflow from the eye without properly correcting the underlying tear-film problem, which is why someone can have both dry-eye symptoms and excessive watering.<\/p>\n

This means persistent watering should not automatically be treated as evidence of a blocked tear duct. Your eye specialist may need to assess the ocular surface, tear film and eyelids before deciding whether the main problem is excessive reflex tearing, poor drainage or a combination of causes.<\/p>\n

How Can Tear-Film Problems Make Your Eyes Water?<\/h2>\n

\"\"<\/p>\n

Your tear film needs to remain stable across the surface of your eye to keep it comfortable. If it breaks up too quickly, your cornea can become irritated and trigger extra watery tears.<\/p>\n

Your meibomian glands help prevent rapid tear evaporation, so problems with these glands can contribute to watering. Your ophthalmologist may therefore check your eyelids and tear film as well as your tear drainage.<\/p>\n

Can Blepharitis and Meibomian Gland Problems Cause Watering?<\/h2>\n

Blepharitis and meibomian gland problems can affect the quality of your tears and cause excessive watering. Poor oil production can make your tears evaporate quickly, irritating your eye and triggering reflex tears.<\/p>\n
