Why Does My Eye Water Constantly?

The tear ducts are located at the inner corner of the eye.

The lacrimal gland above the eye releases tears to keep the eye moist and healthy. Eyes that are constantly tearing, however, may indicate a problem. Excessive eye watering is known as epiphora.

Irritants

When there is something in the eye that shouldn't be there, tears are released to get rid of it. Onions are a common eye irritant but any fume could cause the eyes to water.

Injury

Any type of scratch on the surface of the eye can make it water. A grain of sand or some dirt could cause this.

Conjunctivitis

Conjunctivitis is a common eye infection characterized by tearing, redness and white, yellow or green discharge from the eye.

Entropion

Entropion is a condition in which an eyelid is turned inward or outward. Some of its symptoms are watery, sore or red eyes, eye irritation and corneal scratches.

Cold

Watery eyes, sneezing, a stuffy nose and a sore throat are all symptoms of a common cold.

Allergies

Eye watering is one of the body's ways of defending itself against unfamiliar substances.
