Review on Global Vision Kickback Photochromic Bifocal Motorcycle & Powersports by Jimmy Bores

Works great. The bifocal lenses are nice and clear. Read the box first! You should freeze them for 2 hours and then put them directly in the sun. It also states: 1. They will not work behind UV filtered windshields and that high temperatures above 104 degrees can damage the photochrome. So don't put them on the dashboard and then give them a bad rating like a guy here did. Rschunimagu.
