They are very nice sunglasses and have lasted me several years. The polarized lens make it great when out on the water and even on rainy days. When these wear out I will buy again.To tight but there greatPerfect for ocean fishingThe lenses are awesome low-light lenses, and allow you to see stacks of fish in holes at distance and in depth. The frame is a little bulky, and air flow is a little restricted causing them to fog occasionally when sweating.Price is high but you get what you pay for understanding what lenses you want is important the colors mean different things do your research there's plenty of places like YouTube that explain in depth what each lens isGreat glasses for all day offshore fishingCostas have me a complete believer in their glass lens sunglasses now. That’s all I will wear from now on. I work on boats in sunny hawaiian waters and these things see the bottom when so many other sunglasses will not. They also are incredibly scratch resistant and resistant to that painful streaking of the lens color so many competitors have issues with. I’ve lost so many other sunglasses to spray sunscreen but these will never do that because the glass is actually colored itself making these so amazing. I promise you I wear these hard and they are tough as nails. Also the Amazon ones are completely legit just much cheaper then you get in stores. Buy them you won’t regret itCracked in just 3 monthsBrilliant sunglasses. Polarisation superb .
