There are three kind of basic factor which cause watery eyes. A personal may experience watery eyes due to excessive tear production, inadequate drainage of a normal amount of tears, or inflammation in the eyes. Excessive tear production can actually be stimulated by overly dry eyes, superficial foreign bodies, cranial nerve V irritation, eye strain, and situational occurrences such as vomiting and laughing. Poor clearance of tears can be caused by laxity of the eyelid or obstruction of the tear duct that drains tears to the nose. Inflammation due to conjunctivitis, blepharitis or allergies, for example, can also lead to watery eyes.

Once this is established, her doctor will be able to devise a treatment plan targeted to the specific etiology than can help reduce the excessive water in her eyes.
