Do they offer better sun protection?

From Consumer Reports:
Quote:
Sunlight, especially UVB, contributes to the development of cataracts, vision-clouding clumps in the lens of the eye. So it's a good idea for everyone to wear sunglasses, at least during the warmer months.
How dark the sunglasses are has nothing to do with how well they protect against UV radiation; instead, it's a chemical in or on the lenses that does the job.
Sunglasses labeled as meeting ANSI (American National Standards Institute) standards for general-purpose use block at least 95 percent of UVB and 60 percent of UVA, which is sufficient for most people. Sunglasses labeled as absorbing 99 or 100 percent of UVA and UVB may be best for people with cataracts or who are taking medications that increase the risk of sun-induced skin (and eye) damage. For maximum protection, choose large-frame wraparound sunglasses.

Note that many contact lenses also provide UV protection.
Personally, I like the look of Oakleys, but I can't wear them. When I put on a pair of Oakley wraparound-style glasses, my eyelashes scrape against the lens. I ended up with a nice pair of Gargoyles instead.
