Tears are necessary to lubricate the eyes and wash away foreign bodies and other particles. Excessive tearing, also known as epiphora, occurs when too many tears are produced or when the eyes are unable to drain properly.
A watery eye can be due to many causes. It is essentially an imbalance between the amount of tears being produced by the tear gland and amount that can be removed by evaporation and the tear drainage system. Problems with the eyelid or narrowing of the drainage canals can prevent tears being drained into the nose. Some people have more than one factor causing their watering. Even some people with dry eyes may also experience watering due to reflex tearing as the eye attempts to keep itself moist.
