Yep, I think those are the "Internet Glasses" I've heard of.
Those would be too expensive for me, I would opt for those 99 cent specs that they used to sell on the back pages of comic books.
Not the X-ray goggles, but the ones that have wide open and alert eyes painted on the "lenses". The idea was to allow bored elementary school students to take naps during class without the teacher knowing. My teachers were ALL much too smart for that "old trick".
