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.
Tears normally drain out of the eye and into the nose through ducts located in the corners of your eyes. But people with watery eyes are usually experiencing an overproduction of tears, which are made up of water, oil, and mucous. These excess tears can be caused by: 1  Dry-eye syndrome. 2  It may not make sense, but dry-eye syndrome often leads to watery eyes. 3  When eyes dry out, they become irritated and uncomfortable. 4  That prompts the lacrimal glands to produce so many tears that they overwhelm the eye's natural drainage system.
