THESE SUNGLASSES HAVE A HIDDEN COLOUR CAMERA IN THE FRAME OF THE GLASSES. AND ITS ALL RECORDED TO A PERSONAL VIDEO RECORDER. WHICH IS COOL BECAUSE NO ONE WOULD KNOW THAT YOUR RECORDING THEM. SO NO MORE DEALING WITH THOSE HANDHELD ONES THAT ARE VERY NOTICEABLE WHEN YOUR RECORDING. WHAT YOU SEE IS WHAT YOU GET WITH THESE SUNGLASSES. PRETTY AMAZING RIGHT WHAT WOULD THEY THINK UP NEXT.
