A friend gave me an extra pair that he was not wearing 5 years ago. I instantly was blown away with the clarity, comfort, and how well they cut through the water glare. I am a fisherman and will buy these over and over again. I bought this pair after an unfortunate spill on my kayak and the original pair I had went for a swim. My bad, I didn't have my floating strap on them. I have been wearing these since. I broke a lens on these buy steeping on them. My bad. I sent my glasses to Costa and for a small fee they fixed my glasses quickly and got them back to me. It almost seemed like they replaced them entirely. The picture included is a current picture of them today. I believe they are over two years old and not a scratch on the lenses. They have been dropped and kicked. The glass lenses hold up to scratches very well. They are expensive, but well worth the investment!
