Hindsight cyclist's Glasses for "eyes in the back of your head"

I was looking for something else and found "hindsight" glasses which seem like they'd be great for cyclists (watch for idiots without needing to turn you head).

As the Nike site is garbage I won't bother to link to their site, in any case I assume there are other similar glasses that a google could uncover, I will have a good look later when I have more time...
