Tear over-secretion is usually caused by irritation or inflammation of the surface of the eye. This can occur for a number of reasons, including eyelash and eyelid problems or allergies. Oddly, a dry eye problem can sometimes cause watery eyes, because the eye produces excess tears to combat the irritation and dryness.
Watery Eyes. Tears keep your eyes lubricated and help to wash foreign objects and dust away. When you produce too many tears, they overwhelm your tear ducts, and you develop watery eyes. Glands under the skin of your upper eyelids produce a liquid containing water and salt. When you blink, it spreads and keeps your eyes moist.
