the real question is why aren't you using gunnar optics 
because i only wear glasses to help me focus on what i read. i have a slight astigmatism, so i have a hard time with actually remembering what i read because i have to focus on trying to keep the letters in focus. i don't really do a lot of gaming anymore, anyways.
With your face shape shoulder length hair would look nicer I think. Short but not as short as you have now.
to keep within uniform standards and not have to put my hair up, my hair can't touch the collar of my service coat. and if my hair is too short but still touches my collar, i can't really put it up in a ponytail because there's not much there for it to hold.
