All polarized glasses are definitely not equal. Solar Bats and Kaenons are two good ones, I use the Kaenons with yellow lense and they've been great. The frame really wraps around your head and once they're on they don't move, so no worrying about bending over and them falling off, or turning around when you're running the boat, etc. If you're in the area of bass world west you can try on a pair. Take em outside and look at green objects. I like a lense that picks up a lot of green, it tends to make the bass stand out really well when you're sight fishing.
