Overview: This is basically a jeweler's loupe. It's used to magnify small spots or allow you to be able to concentrate on small spots when sodering, wiring or building tiny things. You can use this magnifier by squinting your eye a bit so that your eyelids will grasp onto the loupe so you can use both hands if needed. It has a good magnification level.
