POWERFUL!
For many people who wear eyeglasses the "Clip-on" eye loupe is a welcome means for viewing items such as jewelry, coins, postage stamps, printed material and any object where fine details are important.

The spring 'Clip-on' allows you to directly attach the clip on to your own glasses and is hinged so that it can easily be flipped up when not in use. The dual lens system has a magnification of 10X when both lenses are in use, 5X when the front lens is removed.
