Snowbee Clip-On, Flip-Up Magnifiers +2.5X

 Designed for the angler who only requires glasses for close-up work, the Clip-on Magnifiers will fit any sunglasses and come in the popular +2.5 magnification. A simple flip-up mechanism allows them to be flipped up under a cap peak when not in use, where they are unobtrusive and virtually undetectable - out of the way until you need them.
