It looks like an ordinary pair of sunglasses. Yet they have a unique feature... you can see behind you! The lenses on these sunglass-style specs have a special reflective coating that allows you to
look straight ahead, yet see behind you as if you had a rear view mirror. When you put them on, look out of the corners of your eyes and youll see whats going on - and no one will ever know youre
watching them.
Have you ever thought you were being followed? You wont need to turn your head to see whats coming up behind you.
