If you are active duty military & require glasses, the military gives you standard issue glasses. They are known as BCG's or "birth-control glasses." Basically nobody is gonna come anywhere near you if you're wearing them. You can pay yourself & buy NORMAL glasses, but they are required to give you a pair of BCG's as well. So Trek has them, but never wears them. Taya found them the other day & now they're her favorite toy. Isn't she a cutie?
