My nephew eyes tear all the time. I know it bothers him and he is constantly having to wipe his eyes and it's usually with his hands. He is 20 years old. When he is 3 years old he was rushed to the hospital and diagnosed with SJS. Twice a day for 30 days his eyes were scraped with an utensil to keep them from forming a film. It did some sort of damage to his eyes. I am not sure if there is anything you can do to help him out.
