Very clever. These surveillance rearview sunglasses (see pic below) allow you to easily see right behind you. I was a bit skeptical before I bought them, but have found them to be of excellent use, whether checking the babes on the beach (it's amazing how girls will strip off their clothes to get changed when you "look the other way").
As you can see, they have a mirrored strip on the outer edge of each glass. And they are totally flat. So all you have to do is to turn your head about 15 degrees (i.e. a tiny bit) to either side, and you have a perfect view of what's behind (Ideally a pair of well-proportioned breasts and their owner changes down to her bikini)..
Rearview spy glasses like this are ideal not only for covertly looking behind you, but also if you ever ride a bike or go inline skating (as in roller blading). Spy glasses are the perfect convenient alternative to a rearview mirror attached to your bike. Bike mirrors tend to break and become misaligned and look silly. As far as roller blading: Have you ever tried using those mirrors attached to your hand? Well... by the time you align it and focus your eyes on what's behind, you've most likely been hit by a bus from the front! The rearview spy glasses, on the other hand, are discreet, cool-looking and superbly useful. It'll save you from a sore neck!
So where did I find mine? Right here. The delivery was prompt and accurate. I have had no problems at all.
