Hello! I am looking to a second pair of goggles, strictly for use on sunny days in open water. I already have a pair of Swedes that I use in every other case, but I need something else for open-water swims in the ocean or lakes. I was looking at both the Kayenne and the Kaiman from Aquasphere, and I noticed that the Kayenne comes in both a polarized and a mirrored lens option. Does anyone have any experience with both of these styles (in any brand) and can comment on what the real-world difference is like? I have always used polarized lenses in my prescription sunglasses, so I am already familiar with how they work. But is there really any advantage to them when you're in the water? Thanks!
