I only owned one pair of Costas - a pair of 400s, and one of the lenses started to delaminate after a surprisingly short period of time. I couldn't believe a pair of sunglasses that cost that much would have that kind of problem. I was going to send them in for a warranty replacement, but then my friend Mike had a pair of Costas that started doing exactly the same thing. I decided it was time to check out a different brand.
After that I fished with Smith Action Optics glasses for quite a while and liked them quite a bit. But then my Smiths got crunched (my fault, not the manufacturer's), and when I was shopping for a replacement pair, I was persuaded to try out a pair of Kaenons.
Now that I've fished with the Kaenons, I don't think I'll go to a different brand. Their clarity is simply the best. I can fish on flats all day in bright sun with their high-contrast copper lenses and still have zero eye fatigue.
