You don't have to focus on the glass device itself. I doubt anyone here even can. It would hurt very soon and you would have an extreme cross-eyed look when trying to see the display. The display is set-up for a focal plane somewhere in front of your eyes. Google mentioned it is equivalent to a 25" at 8 feet distance.
