Why Does My Eye Water Constantly?

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.
