UPDATE: I just received my second set of these sun glasses, my first set lasted over 3 years. Can't say enough good things about them. They are affordable and last. I highly recommend them if you are in need of some shades that will last.

My review from Feb 2012:
I've been wearing aviators for about 10 years, they are always cheap and break, Bought these they've lasted Still on my first pair with two to go. I just wish the lenses were a little darker.
