Why Are My Eyes Watering? Common Causes and Treatments

Watery eyes can be frustrating and uncomfortable. Whether your eyes tear up while reading, driving, working on a computer, or simply walking outside, excessive tearing can interfere with your daily activities and make it difficult to see clearly.

Many people assume watery eyes mean they’re producing too many tears, but surprisingly, that’s not always the case. In fact, dry eyes are one of the most common causes of excessive tearing. When your eyes become too dry, they produce extra reflex tears in an attempt to protect the surface of the eye.

While occasional watery eyes are usually nothing to worry about, persistent or excessive tearing may indicate an underlying condition that should be evaluated by an optometrist.

What Causes Watery Eyes?

Your eyes constantly produce tears to keep the surface of the eye moist, comfortable, and protected. Normally, these tears drain through tiny openings located in the corners of your eyelids.

When this balance is disrupted—either by producing too many tears or by poor tear drainage—your eyes begin to water.

Several different conditions can lead to excessive tearing, making a professional eye examination the best way to identify the exact cause.

Dry Eyes

It may sound surprising, but dry eye syndrome is one of the leading causes of watery eyes.

When your eyes don’t produce enough high-quality tears, they become irritated. In response, your body releases an excessive amount of watery tears that often overflow onto your cheeks.

Common symptoms include:

• Burning eyes

• Stinging

• Redness

• Blurry vision

• Eye fatigue

• Excessive tearing

Treating the underlying dry eye problem often reduces watery eyes significantly.

Allergies

Seasonal allergies are another common cause of watery eyes.

Pollen, dust mites, mold, pet dander, and other allergens can irritate the eyes, causing them to become watery, itchy, and red.

If watery eyes occur mainly during allergy season or after exposure to specific triggers, allergies may be responsible.

Avoiding allergens and using appropriate allergy treatments can help relieve symptoms.

Eye Infections

Certain eye infections, such as conjunctivitis (pink eye), often cause excessive tearing.

In addition to watery eyes, you may notice:

• Redness

• Swelling

• Eye discharge

• Crusting around the eyelids

• Light sensitivity

Eye infections should be evaluated promptly to determine whether treatment is needed.

Blocked Tear Ducts

Normally, tears drain through small channels into the nose.

If one of these tear ducts becomes blocked, tears cannot drain properly and begin overflowing onto the face.

Blocked tear ducts are more common in infants and older adults but can occur at any age.

An eye care professional can determine whether poor tear drainage is causing your symptoms.

Environmental Irritants

Your eyes are very sensitive to the environment around you.

Common irritants include:

• Smoke

• Wind

• Air pollution

• Chlorinated swimming pools

• Strong perfumes

• Dust

• Chemical fumes

These irritants stimulate tear production as your eyes attempt to wash away the particles causing irritation.

Wearing sunglasses outdoors and avoiding irritants whenever possible may help reduce symptoms.

When Should You See an Optometrist?

Occasional watery eyes are common and often improve on their own.

However, you should schedule an eye exam if your watery eyes:

• Last for several days

• Occur frequently

• Affect only one eye repeatedly

• Are accompanied by pain

• Cause blurry vision

• Produce yellow or green discharge

• Are associated with swelling or redness

These symptoms may indicate an underlying eye condition requiring professional treatment.

How Are Watery Eyes Treated?

Treatment depends entirely on the underlying cause.

Your optometrist may recommend:

• Artificial tears for dry eyes

• Allergy eye drops

• Prescription medications

• Warm compresses

• Eyelid hygiene

• Treatment for infections

• Further evaluation for blocked tear ducts

Because many different conditions can cause watery eyes, self-diagnosis is not always reliable.

A comprehensive eye exam helps ensure you receive the most appropriate treatment.

Frequently Asked Questions

Why do my eyes water even though they feel dry?

Dry eyes often trigger the production of reflex tears, which are watery but don’t effectively lubricate the eye. This is one of the most common causes of excessive tearing.

Can allergies cause watery eyes?

Yes. Allergies are a common cause of watery, itchy, and irritated eyes, especially during pollen season or after exposure to pet dander or dust.

Why is only one of my eyes watering?

A blocked tear duct, localized irritation, or an eye infection can sometimes affect only one eye. A professional eye exam can determine the cause.

Are watery eyes a sign of an eye infection?

They can be. If watery eyes are accompanied by redness, swelling, pain, or discharge, an eye infection may be responsible and should be evaluated promptly.

When should I be concerned about watery eyes?

You should see an optometrist if excessive tearing is persistent, painful, affects your vision, or is associated with redness, swelling, or discharge.

Watery eyes are a common symptom with many possible causes, ranging from dry eyes and allergies to infections and blocked tear ducts. While occasional tearing is usually harmless, persistent or excessive watery eyes should never be ignored.
