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.
Dacryocystitis is an infection of the tear sac (lacrimal sac) in the inner corner of your eye. Tears drain through this sac as they leave your eyes. Tears help keep your eyes hydrated, clean, and free of bacteria. The lacrimal glands underneath your upper eyelids produce tears, which travel through small openings to the front of your eye. Every time you blink, the tears spread across your eyes.
