Re: Which prescription bi-focal polarized sun-glasses?
Habervision. Get the amazing Drivewear lenses. They work in all light conditions. Polarized prescription bi-focals for me! I've worn Smith and Costas, and these are the best I've ever had. And the price is definitely as low as any quality glasses out there, and beat the big names hands down. PM me for more info if you'd like it. I'm a huge fan of Habervision, an on-line polarized glasses company in Golden, Colorado founded by Steve Haber, of Bolle' fame.
