I used to work for an independant sunglass retailer. Check out www.fowlerspharmacy.com David Maney runs the place and he'll ship anywhere. The pilots of Air Force One wear sunglass from him. He loves to tell that story. After lasik surgery I wear revos or costa del mars but most quality sunglasses will do the job. I think you should look at polarized lenses to help with glare. Other than that it's up to what you like and how they fit. I have a new pair of Harken sunglasses that don't fit me very well, if you like them I'll make you a good deal.

PS A trick to test if lenses are polarized. Look through the lens at a digital watch. if you rotate the watch to 90 degrees the the face will go blank. You can also look through two polarized lenses at the same time holding them up to the light, if you rotate them 90 degrees to each other you can't see through them
