Vista hidden bifocal with polarized magnetic snap on lens
Polarized reading glasses are expensive, and even more expensive when they are bifocal. These hidden inner bifocal reading glasses come with a magnetic polarized sun "snap" on. The design is so sleek, you can't even TELL you're wearing a clip on, they just magically "snap" in place perfectly via magnetic attraction. Not only is this a GREAT value for full lens single vision polarized sun reading glasses, but you're getting two for one. Take the sun clip on off, and you can wear the clear inner bifocal indoors.
