No sub vol here. Will I get to wear my normal glasses or contacts after boot? Please say yes... 
Sorry to go over stuff already covered... I tried to read this whole thread but it seems as though it was merged with others and I had trouble following at times. Plus, I need a glossary of acronyms to have any idea of what's going on in this forum! 
Seriously, you need to get over the glasses. Yes, you can where what you want. Yes you will be given submarine glasses that you will need to wear. Why? Because they are designed to fit under an EAB so that you can breathe when a fire breaks out. Now, you choose... fancy glasses or life if it comes down to it? And no, you cannot take them off to put on your EAB. What good are you if you can't see your panel or what you are operating? I have seen that before where some student RO didn't want to reck his armani's with an EAB. Then he couldn't shift pumps. Needless to say, he didn't pass the watch. Anyway, point is that unless you are gay (don't ask don't tell), then there is no need for you to worry about what you look like when you are underway, submerged with a bunch of dudes. Then again, it isn't gay when you are underway so you can ignore everything I just said.

PS Yes you can wear contacts, but I promise you (as a former contact wearer) that after one day underway, you won't want to be wearing them anymore.
