My grandma sells sunglasses, so I have connections
For the last couple of years I've had a wonderful pair of Mosley Tribe sunglasses. Mosley Tribes is a subsidiary of Oliver Peoples. The Mosley Tribes have a glass lens, so they're a bit heavy, but it's a very high quality, polarized lens. Quick aside: Last summer my car got broken into. There was nothing in the car to take, not even spare change. They did take the case for my sun glasses, but they left the actual sun glasses (Which were not in their case).
I was just up to see grandma and she sent me away with a new pair of shades.
Oliver Peoples Boxley. Clear with green lens. Quite a bit different than my Mosley Tribes, which are a square-aviator style design, but a fun sunglass.
She sells Maui Jim, Tag Huer, Oakley, Smith, Ray Ban -- all great brands. Somebody mentioned the Sport-Clic glasses too. She sells those too. They are displayed on a fun stand that demonstrates their unique feature -- they magnet at the temple to the stand, but the notches that they magnet into are slightly offset, so you have a row of glasses with the right-sides slightly higher than the left. Certainly makes you do a double take!
