These apparently use a lens of some sort to allow the eye to focus at 5' while wearing them. I had the chance to play with a pair of these 10 years ago. At that time, the resolution sucked and they were about 1.5" thick. They had built-in motion tracking. Playing Descent with those things was a blast! :) -- Bowie
