Sorry for resurrecting the old post... But I actually have an answer to the original OP question. The "invention" is hardly an optical novelty or even application of optics to glasses. These have been around at least since the 50s and they're called "bed prism glasses" or "prism glasses", but unlike belay googles your field of view points down instead of up. The inventor turned the prisms around. Googling or baying for those glasses returns lots of hits, the lowest one I've seen was 30 bucks. Those glasses allow you to read or watch tv while you're lying down. If you're going to buy bed prism glasses and invert the prisms, be sure to line them up carefully or you can get your eyes messed up.
