Constantly watery eyes can blur your vision, irritate the skin around your eyes, and make it look like you’re crying when you’re not. If you’ve been wondering why one or both eyes keep tearing up, you’re not alone.
The medical term for this is epiphora. Understanding the underlying watery eyes causes and treatment options can help you get the right care quickly. Some causes are minor and easy to treat at home. Others particularly when symptoms persist or affect your vision need professional evaluation.
This guide covers the most common causes, practical treatments, lifestyle adjustments, and clear guidance on when to visit an eye specialist.
Healthy tears are produced by the lacrimal glands above each eye. They coat the surface of the eye in a three-layer film oil (from the meibomian glands in the eyelids), water, and mucus before draining through small openings called puncta near the inner corner of each eye into the nasolacrimal duct.
Excessive tearing occurs when either too many tears are produced (reflex tearing, usually due to irritation) or when tears cannot drain efficiently (usually due to a blocked tear duct or anatomical issue).
Paradoxically, dry eyes causing watery eyes is one of the most frequent complaints in eye clinics. When the tear film is unstable due to insufficient oil from the meibomian glands or poor tear quality the eye’s surface becomes irritated. The lacrimal glands then flood the eye with watery reflex tears, which provide temporary relief but don’t address the underlying dryness.
Typical symptoms: Burning or stinging sensation, grittiness, fluctuating vision, and excessive tearing often worse in wind, air-conditioned environments, or after prolonged screen use.
What helps: Preservative-free artificial tears (used consistently), warm eyelid compresses, limiting screen time, and using a humidifier indoors. Speak to a specialist about dry eye treatment options if symptoms are frequent.

Blepharitis is chronic inflammation of the eyelid margins, often caused by bacteria or skin conditions like seborrheic dermatitis. A common underlying factor is meibomian gland dysfunction (MGD) where the oil-producing glands in the eyelids become blocked, leading to an unstable tear film, lid inflammation, and secondary watering.
Typical symptoms: Crusting or flaking at the base of the lashes (especially in the morning), red eyelid margins, a gritty or burning sensation, and frequent tearing.
What helps: Twice-daily warm compresses (to soften blocked gland secretions), gentle lid margin cleaning with gentle lid hygiene with a clean warm cloth or specialist lid wipes, and where inflammation is significant a short course of antibiotic eye ointment or drops as prescribed by your doctor.

Allergens such as pollen, dust mites, pet dander, mould, and air pollution trigger the release of histamine in the eye’s conjunctiva. This causes the characteristic itching and watery discharge of allergic conjunctivitis.
Typical symptoms: Intense itching, redness in the whites of the eyes, watery discharge, eyelid swelling, and symptoms that worsen seasonally or in specific environments.
What helps: Antihistamine eye drops (mast cell stabilisers for long-term control), cold compresses, avoiding known allergens, and oral antihistamines where needed. Learn more about allergy eye treatment at Skipper Eye-Q.

Bacterial or viral infection of the conjunctiva is another common cause of watery or sticky discharge from the eye. Viral conjunctivitis often associated with an upper respiratory infection typically causes profuse watery discharge and spreads easily. Bacterial conjunctivitis produces thicker, purulent discharge and tends to cause the eyelids to stick together overnight.
Typical symptoms: Redness, watery or purulent discharge, crusting of the eyelid margins, and in viral cases swollen lymph nodes in front of the ear.
What helps: Bacterial conjunctivitis may require antibiotic eye drops prescribed by a doctor. Viral conjunctivitis often improves with supportive care, but persistent or severe symptoms should be assessed; cold compresses provide symptomatic relief. Avoid sharing towels or touching the eyes to prevent spread.
If the drainage channel becomes partially or fully blocked, tears overflow onto the face rather than draining normally. This is a common reason why one eye keeps watering without any obvious irritation or infection.
Typical symptoms: Constant watering from one eye, recurrent sticky discharge (even without active infection), swelling or tenderness at the inner corner of the eye, and recurring eye infections.
Blocked tear ducts are more frequent in newborns (often self-resolving within the first year), older adults (due to age-related narrowing), and people with a history of sinus problems or facial trauma.
What helps: Warm compresses to encourage drainage; lacrimal massage for infants as taught by an eye specialist. Persistent blockages may require procedures such as syringing, probing, or dacryocystorhinostomy (DCR), depending on the cause. Explore blocked tear duct treatment at Skipper Eye-Q.
The eyelids play a critical role in spreading tears evenly and directing them towards the drainage puncta. When the lower eyelid turns outward (ectropion) or inward (entropion), tear drainage is disrupted, causing overflow tearing and in the case of entropion irritation from lashes rubbing against the cornea.
Typical symptoms: Persistent watering, eye irritation, visible turning of the lower lid, or lashes touching the eye surface. More common in older adults.
What helps: Lubricating drops provide temporary relief. Definitive treatment is usually a minor surgical correction performed by an oculoplastic specialist. Our oculoplasty team manages both ectropion and entropion repairs.
Wearing contact lenses for longer than recommended, using lenses that are not cleaned properly, or using lenses that are not the right fit for your eyes can all irritate the ocular surface and trigger reflex tearing. Giant papillary conjunctivitis (GPC) , an immune reaction to contact lens wear, is a less common but important cause.
What helps: Following your wearing schedule strictly, cleaning lenses as directed, replacing lens cases regularly, and switching to daily disposables if recurring irritation occurs. If watering continues, a contact lens review with your eye specialist is recommended.

A scratch on the cornea or a particle trapped under the eyelid triggers an immediate protective tear response. Even something as small as an eyelash or fragment of dust can cause significant pain and watering.
Typical symptoms: Sudden eye pain, light sensitivity, a sensation of something in the eye, and profuse watering.
What helps: Do not rub the eye. Rinse gently with sterile saline. If discomfort persists beyond a few minutes, seek urgent assessment of corneal injuries that need prompt evaluation to prevent infection. Our cornea specialists can assess and manage corneal injuries.
Most causes of watery eyes are not emergencies, but the following symptoms need prompt evaluation do not wait:
Swelling, redness, or a hard lump at the inner corner of the eye (may indicate a blocked tear duct with acute infection dacryocystitis)
Chemical splash to the eye rinse immediately with running water for at least 15–20 minutes and seek emergency care
Early assessment prevents complications. Book an urgent appointment or contact your nearest Skipper Eye-Q clinic directly.
Treatment depends entirely on cause — managing symptoms without addressing the root problem rarely gives lasting relief. Here is a step-by-step approach:
Is it one eye or both?
Is there itching (suggests allergy), burning (suggests dry eye), or discharge (suggests infection)?
Is it worse in certain environments, seasons, or after screen use?
Did it come on suddenly (suggests foreign body, injury, or infection) or gradually (suggests a chronic condition)?
Warm compress (10 minutes, twice daily): Most useful for blepharitis, MGD, and mild blocked tear ducts.
Cold compress: Helps reduce itching and swelling from allergies or conjunctivitis.
Preservative-free artificial tears: Suitable for dry eye, digital eye strain, and mild environmental irritation. Use consistently rather than sporadically.
Lid hygiene: Gently clean eyelid margins with warm water and a clean cloth or specialist lid wipes if blepharitis is suspected.
Minimize screen time and apply the 20-20-20 rule.
Avoid smoke, dust, and strong fumes where possible.
Keep well hydrated and reduce excessive caffeine intake.
Sleep adequately worsens tear film stability.
Some medications can worsen dry eye symptoms, including certain antihistamines, antidepressants, and other systemic medicines. If symptoms begin after a medication change, discuss this with your doctor.
Home measures are a starting point, not a substitute for diagnosis. If watering continues for more than one to two weeks, or if any of the red-flag symptoms above appear, a professional examination is needed to identify the cause accurately and start targeted treatment.
Watery Eyes in Specific Groups
Babies and Young Children
Up to 20% of newborns have an incompletely opened nasolacrimal duct at birth. This typically presents as persistent watering and sticky discharge from one eye, without redness. In most cases the duct opens spontaneously within the first year. Gentle lacrimal sac massage (as demonstrated by an eye specialist) can help. If the obstruction persists beyond 12 months, probing under brief anesthesia is a straightforward and effective procedure.
Older Adults
Age-related changes including narrowing of the puncta and nasolacrimal duct, weakened lower eyelid tone predisposing to ectropion, and reduced meibomian gland function make epiphora significantly more common in older patients. Treatment ranges from lubricating drops to minor surgical correction depending on the cause.
Hormonal Changes (Pregnancy and Menopause)
Hormonal fluctuations can affect tear gland secretion and tear film composition, worsening dry eye and triggering reflex tearing during pregnancy and menopause. Preservative-free lubricants are safe during pregnancy; more specific treatment should be guided by a specialist.
If your watery eyes are persistent, affecting daily life, or accompanied by other symptoms, an in-person evaluation is the most reliable way to identify the cause.
At Skipper Eye-Q, ophthalmologists use slit-lamp examination, tear film assessment, and where indicated nasolacrimal duct syringing to distinguish between the most common causes: dry eye and MGD, blepharitis, allergic or infective conjunctivitis, blocked tear duct, and eyelid malposition. Treatment is tailored to the specific diagnosis rather than a generalised approach.
We offer dedicated clinics for dry eye, ocular allergy, blocked tear duct, and oculoplasty. You can book an appointment at our Lagos or Abuja locations.
Unilateral watering most often points to a cause on that side alone: a blocked tear duct, a corneal abrasion, a foreign body, a localized infection, or an eyelid malposition. Bilateral causes like dry eye and allergy tend to affect both eyes, though not always equally. A unilateral symptom persisting beyond a few days should be assessed by an eye doctor.
Yes, this is one of the most common and misunderstood causes. When the tear film is poor quality (typically due to meibomian gland dysfunction), the eye surface becomes irritated and the lacrimal gland responds by producing excess watery reflex tears. These tears overflow without providing proper lubrication. Preservative-free artificial tears, warm compresses, and treatment of the underlying MGD usually break this cycle.
Yes. Allergic conjunctivitis is a very common cause of ongoing watery eyes, particularly during pollen season or with prolonged exposure to dust and pet dander. The key distinguishing feature is itching if your eyes are very itchy as well as watery, allergy is the most likely cause. Antihistamine eye drops and avoidance of triggers are the first steps.
The hallmark of a blocked tear duct is persistent watering from one eye even without any irritation or infection. Other signs include sticky or crusty discharge, recurrent eye infections, and in acute cases redness and swelling at the inner corner of the eye (dacryocystitis). A blocked tear duct in adults often persists and usually needs specialist assessment.
If watering has not improved with home measures after one to two weeks, if it is affecting one eye only, if your vision is changing, or if there is pain, light sensitivity, significant redness, or discharge see an eye specialist promptly. The sooner the underlying cause is identified, the sooner targeted treatment can begin.
