Everytime I go to MVP Sports I see the Polaroid brand polarized sunglasses for <30 buckaroos.. I wonder if they would do the trick since they invented polarized lenses. I'm with Gregg, loose too many to buy Mauie Jims. I remember one day fishing a railroad bridge over the Parker river. I looked down into the current and my nice Vuarnets slide off and bye bye. Interesting about the polycarbonate though.
