I have these. They are my “boat glasses”. I have a Sea-doo jet boat that is fairly fast and it is common for a wave to come over the boat and knock the glasses off your face. I keep a bin of several cheap glasses on the boat for guest that forget their sunglasses so it doesn’t spoil their day.
These sunglasses look pretty nice but they are not polarized despite what it says on the box! If you snap a pair of polarized glasses in half, then put the lenses on top of each other, you can rotate one lens and watch the transmission of light decrease and increase. Or if there are two sunglasses in the box, you can just put one lens from each pair in the same path. I wonder how they get away with labeling them as polarized when they are not. But they are pretty cool looking so I am going to keep them.
