I've been wearing Blublocker Vipers and Super Vipers for about twelve years now, Paddy, and love 'em. My only complaint about them is the lens coating is a trifle delicate.
I'd seen the infomercials and didn't like the aviator-style frame, and then one day while making a delivery at a Walgreens (I worked for a courier service back then) I saw a display of the Vipers. Wearing contact lenses at the time, wraparounds were what I wanted to keep the breeze from drying them out. I liked the crispness of view and found they're a downright blessing when driving in the rain. When you're in a daytime driving rain and it's bouncing up off the road, and tire spray is added to it, it's hard to see the vehicles around you, even with their lights on. Blublockers cut through all that mess.
I had Lasik surgery last year and ditched the contacts but still like my Vipers. I get quite a few compliments on them, too.
The ones in your photo look like Eagles. The company doesn't offer those in polarized but does have a polarized style called Starmask that are semi-wraparound.
You can get clip-on lenses, even polarized ones, to put on your prescription glasses if you want to go that route.
http://blublocker.com/The first few pairs I bought off the shelf but since the company website went up, I think it was about 2000 or 2001, that's where I've got all mine. The price has gone down since I first bought them. My first pair was $21.95, a few years later they were $24.95, and now are going for $14.95.
