For my christmas/graduation gift, my aunt wants to buy me (give me money for) a nice pair of sunglasses. I noticed several cadets wearing some when I visited USAFA this summer, as well as in many of the photos online. I was wondering what kind of guidelines you have to follow for those? I'd like to be able to bring mine with me if possible, but I'd hate to not be allowed to for some regulation or another. Now that I think of it, are you allowed to bring your own in the first place? Thank y'all!
