Ever got that feeling that somebody else is just looming behind you, but when you turn around, there’s nobody there? This pair of $10 Spyglasses provides the answer.

These ordinary looking sun glasses have a unique feature…you can see behind you. They have a special coating that allows you to look straight ahead and still see what is going on behind you. A great novelty item.

If you’re paranoid enough about having somebody trail you all the time, I must say getting a pair of these is imperative.
