What It Means

What Watery Eyes Mean

Watery eyes, also called epiphora, happen when the eyes produce more tears than usual or when tears cannot drain normally. A thin tear film usually keeps the eye lubricated, clear, and protected before tears leave through tiny openings near the inner corner, pass through the tear ducts, and drain into the nose. Excess tearing may affect one eye or both, and can also be described as teary eyes, runny eyes, or eye watering.

Urgent eye symptoms

Seek urgent medical care rather than treating the tearing at home if you have:

  • sudden vision loss or major vision changes;
  • severe eye pain;
  • a chemical splash or penetrating eye injury;
  • marked swelling;
  • severe redness with light sensitivity; or
  • watery eyes after a significant injury.

Possible Causes

Possible Causes of Watery Eyes

  • Allergies can cause itching, irritation, and excess tears, sometimes along with a runny or stuffy nose.
  • Dry eyes may trigger reflex tearing as the eye tries to restore its protective tear film.
  • Wind, smoke, dust, cold air, or fumes can briefly irritate the eye and increase tear production.
  • A foreign body, such as an eyelash or speck of dust, can cause surface irritation and watering.
  • Conjunctivitis may cause watery eyes with redness, itchiness, discharge, or discomfort.
  • An eyelid that turns inward or outward, or does not close properly, can disturb the eye surface and tear flow.
  • Blocked or narrowed tear ducts can prevent tears from draining, causing ongoing or one-sided tearing.
  • Contact lenses may cause watering when they are dirty, worn too long, damaged, or poorly tolerated.
  • Less common eye or surrounding conditions can also cause persistent tearing and may need an eye examination.

When only one eye keeps watering, a local irritation, eyelid problem, or drainage issue may be more likely than a general trigger. Watery eyes and a watery nose can occur with allergies or a respiratory infection. These patterns do not by themselves identify the cause, but they can help an eye-care professional decide what to examine.

Relief Tips

How to Relieve Watery Eyes

  • Avoid smoke, dust, wind, and known allergens when possible.
  • Wear protective eyewear outdoors in windy, dusty, or bright conditions.
  • Wash your hands and avoid rubbing your eyes.
  • Remove contact lenses if they irritate your eye, and follow the lens-care instructions.
  • Use a clean warm compress over closed eyes only if it feels comfortable.

Preservative-free artificial tears may help when dryness is triggering reflex tearing. Follow the product label and ask a pharmacist or clinician which eye drops are suitable for you; redness-relief drops are not a general solution for watering eyes.

When to See a Doctor

When to See a Doctor About Watery Eyes

An eye-care professional should assess watery eyes that are persistent, recurrent, unexplained, mainly affect one eye, interfere with reading or driving, or do not improve after you remove an obvious irritant. An examination can help identify whether excess tear production, surface irritation, an eyelid problem, or blocked drainage is involved.

  • Eye pain or increasing discomfort
  • Significant redness or discharge
  • Light sensitivity
  • Blurred or changed vision
  • Swelling around the eye
  • A sensation that something is stuck in the eye
  • Watering after an eye injury

Complications

Possible Problems From Ongoing Watery Eyes

Constant tearing of the eyes can leave the skin around them sore or irritated and may lead to repeated rubbing. Tears can also cause temporary blurred vision, make contact lenses difficult to wear, and disrupt reading, driving, sleep, or outdoor activities. If an eye will not stop watering, these effects may continue until the cause is addressed.
