I was very fortunate to have been wearing the Polarized AirRage glasses over Memorial Day weekend when I rode with some family down to North Carolina. I was wearing them when a stone from the tire of a truck in front of me struck me in the right lens of my glasses. It was big enough to scare the hell out of me, but the glasses stayed in one piece. I have no doubt that if I was wearing my regular sunglasses, I would have been injured that day. Mike L.
