Can i join the military if i use to have ocular herpes?

Key is "used to": When was your last outbreak? How many times has it recurred? What kind of permanent damage has it caused? This one is going to be very individualized - on a case-by-case basis. You have to be able to pass all the vision testing, especially if you are going for officer, USMA, SF, airborne or diver MOS. The key will be in providing excellent documentation (clear narrative) not opthy shorthand.
