Eyes become watery when they are irritated and the eye is attempting to wash away the irritant.
Some common irritants include allergies, the common cold, cosmetics, soap and smoke. Infection in the eyelid is also a common cause of watery eyes.
It is important to seek medical attention if the tearing is unexplained and continues for a long period, there is excess discharge, there is eye pain, or if there is tenderness near the nose.
The doctor will examine the patientâs eyes and ask a variety of questions concerning symptoms and medical history to determine the best treatment plan.
Treatments include antihistamines, antibiotics and artificial tears. In rare cases surgery may be necessary.
