if you're looking for sport-specific sunglasses on the cheap, i can't recommend performance (
a house brand for a big biking retailer) (no affiliation) enough. i recently lost my (9 year old) oakley pro m-frames and needed a pair of sunglasses for playing golf and running in. a friend suggested performance and i couldn't be more pleased. they're light, come with 3 sets of lenses for varying sun conditions, fit extremely well, and have 'open' frames (no frame material on the bottom of the lenses) which is crucial for golf sunglasses. i'll never pay $120+ for a pair of sport-specific oakleys again.
i am still looking for a pair of everyday sunglasses. can some one suggest a pair of sunglasses that are big, boxy, and black in the $100 area?
