No one ever bothered to tell me that it wasn't going to be a band across that had a non-linear top to bottom gradient, but that instead it would be more like a dart board or bulls eye, which means you have to stare absolutely straight ahead, and turn your entire head to see anything not directly in front of you, and that you would have pretty much no peripheral vision whatsoever.
Even if computers didn't exist, my advice would still be
AVOID THEM LIKE THE PLAGUE!
My other rant is about how the only thing available anymore are those ugly skinny frames where the lens height is no more than the width of 2 fingers, and for someone as nearsighted as I am, who needs something that gathers in lots of light, that would still be totally inadequate even if they weren't hideous looking.
But, hey, they save 37 cents worth of plastic and get to jack up the retail price by $20 or more because ironic hipsters or something.
