The problem is google glass is a pair of glasses, that is the main part of it is transparent. Hows this for an idea instead of it being a pair of glasses, what if it was a pair of camera phones that you wear on your eyes? In it normal mode it gives you a real time 3 dimensional live video feed of what is in front of you. The phone would eliminate contrast and glare, and also give you image enhancement at night. There would be two screens on both sides of the phone as well as two cameras, the screen on the outside would produce an image of your eyes.
