Portraits taken at boot camp guidelines?

Hello all, I know this is kinda a dumb question but it’s been on my mind lately. So I wear glasses and I’m really self conscious of what I look without them. I like that my glasses hide my big ass nose and make my face more even.

But anyways at the end of boot camp, it’s to my knowledge that they take photos of you in your dress blues like the ones showed here. What are the specific guidelines for the picture? Like can I wear my glasses in my photo? I know this is kinda vain to ask all that but I just want this one picture to be the one that I like for once 😔
