I have been wearing polarized sunglasses for over 2 decades. Everything from Costa to Maui to Smiths and more. These Kaenons are just incredible. The only thing I have tried with the same clarity is Costa and Maui in glass only. Their poly lenses do not compare. They really are as clear as glass! Not sure how they do it in an impact lense, but it works. I live on Long Island so naturally spend a lot of time around the water. These glasses excel for all water sports. I fish a lot, some off a boat and a lot of surf fishing. I wear them all the time in the surf and they get covered with salt spray and sand all the time. Just a quick rinse and they are fine. They fit my large face great with no pinching and are comfortable all day. The wrap style provides great coverage. Highly recommended!!!
