I'm 15 with the same type of Duane's syndrome, except in my left eye. I am managing my life great. I'm driving and I am in all higher level classes and playing sports successfully. I do have a stable, minimal head turn that most people don't even notice. The whole explaining thing is just a simple, "no I don't have a lazy eye, I have Duane's Syndrome." It's not to bad, he will learn to cope as I have. I actually like to have a little fun with my eye by crossing the one while the other doesn't move. It tends to freak my friends out, and then they try to do it. Hope this helps to ease your conscience a little bit.
