Watering eyes happen when you make too many tears or your tears cannot drain away properly, often because the tear duct is blocked or narrowed. It is common in babies and in older adults. Many cases settle on their own or with simple measures, but a persistently blocked tear duct can be treated with a procedure or oculoplastic surgery to restore normal drainage. General UK health information, not a diagnosis. In an emergency call 999 ; for urgent advice use [NHS 111](https://111.nhs.uk/) (GP out-of-hours in Northern Ireland). On this page 5 sections ## Key facts about watering eyes and blocked tear ducts - Watering eyes are caused by too many tears or poor tear drainage. - Blocked tear ducts are common in babies and often clear by age 1. - In adults, a narrowed tear duct can cause a constantly watering eye. - A persistent blockage can be treated with a procedure or surgery. ## What causes watering eyes? Tears keep the front of the eye healthy and then drain away through tiny channels at the inner corner of each eye into the nose. A watering eye happens when this balance is upset — either too many tears are made, or they cannot drain away properly. ## Too many tears Ironically, dry or irritated eyes often water, because the irritation triggers a flood of tears. Wind, allergies, an eyelash rubbing the eye, or an eyelid that turns in or out can all cause watering of this kind. ## Poor drainage If the tear-drainage channels are narrowed or blocked, tears spill over the lid instead of draining. This is common in babies, whose ducts are often not fully open at birth, and in older adults, where the ducts can narrow with age. ## Treatment Treatment depends on the cause. Babies usually need only gentle massage and time. In adults, options range from treating the underlying irritation to [oculoplastic and orbital surgery](https://healthanswers.co.uk/treatments/oculoplastic-surgery/) — such as an operation to create a new tear-drainage channel — when a blockage will not clear. ## When to seek help See a GP if watering is persistent or troublesome. Get **urgent** help for a painful, red, tender swelling at the inner corner of the eye, or for any change in your vision. ## !

Either your eye is making too many tears, often as a reaction to dryness, wind or irritation, or the tears are not draining away because the tear duct is narrowed or blocked. An eye specialist can work out which it is. Do babies' blocked tear ducts need treatment? Most blocked tear ducts in babies clear on their own by around their first birthday. Gentle massage and keeping the area clean can help. See a GP if the eye becomes red, swollen or repeatedly infected. How is a blocked tear duct treated in adults? If simple measures do not help, a blocked tear duct can be treated with a procedure to open the drainage system, or with an operation called a DCR that creates a new drainage channel. Both aim to stop the constant watering. Is a watering eye serious? Usually not, but a painful, red, swollen inner corner of the eye can mean the tear sac is infected and needs prompt treatment. Any change in vision should also be checked urgently. ## Sources - [NHS — Watering eyes](https://www.nhs.uk/conditions/watering-eyes/) ## How we reviewed this page Medically reviewed by [Mr Mohamed Mohyudin](https://healthanswers.co.uk/our-doctors/mohamed-mohyudin/), MBChB, FRCOphth Consultant Ophthalmic Surgeon · GMC [7039600](https://www.gmc-uk.org/registrants/7039600) Mr Mohamed Mohyudin is a Consultant Ophthalmic Surgeon based in Yorkshire, working at Spire Elland Hospital and Newmedica.
