There are many respectable historic figures with eye patches. I vividly remember Moshe Dayan. He was shot by a sniper while holding binoculars and it took out the eye ball and a lot of bone / soft tissue, so he had to wear a patch. He was not only a soldier, general and politician but also a womanizer, so it probably worked for him as well.
Good Luck to your son - with the ladies and otherwise!
