You must wear glasses during BCT. You will fill out a form in your acceptance package, where you will include a valid prescription, and they will have a pair of BCG's (Birth Control Glasses) waiting for you when you arrive for BCT. After BCT, you will be allowed to wear contacts or your own personal eyeglasses (Within regulations; mean no mirror lenses, funkadelic colors, etc...) if you'd like to. Best of luck. Mike.....
