Good Evening All-
Ray Ban, Vuarnet, Oakley, Revo, Bolle, and Gargoyles have been my sunglasses of choice at one point or another over the past twenty years. In addition to materials, lens color, and styling...one must consider use.
Polarized is great for driving, shooting, fishing, and other general use...but it is a disaster for skiing or snowboarding where glare is actually needed to identify icy spots. My favorites for skiing and snowmobiling have been Revo and Vuarnet.
For active, sweaty sports like running, bicycling, and hiking, I have come to prefer the light weight of polycarbonate lenses found in Oakleys and Gargoyles. The gray color allows for reasonable color recognition.
For driving, businesswear, or other general use I tend to favor Ray Bans and Revo...minus the buglike colored reflectors. They block the harsh light, but not so much that you're blind going through a tunnel or driving under tree canopies. If riding a motorcycle, you'll want the bayonet earstems to allow for easy on/off with a full-face helmet.
Polycarbonate is lighter, shatter-resistant, but is prone to scratches. Glass has superior clarity, doesn't scratch as easily, but does have a weight penalty...especially if you get them ground to prescription-strength.
