Yes, BCG's (Birth Control Glasses). Trust me; if you are wearing them, there is no way in the world any girl or guy would be attracted to a person wearing them. Hence, the perfect birth control. I have to admit however, that if you normally wear glasses, you definitely will want the BCG. You can beat the hell out of them and they are almost indestructible. And you definitely will get bounced around a lot in basic. Beats the hell out of breaking a $300 pair of ultra thin transition glasses. later... mike....
