Ok these are some of the most overrated glasses they are more for status symbol than anything else I am an avid offshore inshore freshwater fly fishing maniac I have always had Calcuttas they are cheap they fit comfortable and they work. So I finally caved in and got a pair of costas first off they are cheaply made the glass lenses don't fit into the frame like at all you can see light in between the lens and frame I have provided pictures to show. And besides the lack of quality or quality control the glasses when flexed make all kinds of creepy crackly noises and movements where as my Calcuttas just flex no loose connections at the ear piece screw and the whole lens wiggles they are also on the short side as in your whole under eye is exposed and letting light in these have to be the worst sunglasses ever and belong on the rack in a gas station definitely getting my $200 back from this hack company don't need costas to see the fish
