these are my favorite glasses from Smith, without a doubt. I can wear them for an entire day of fishing and my eyes wouldn't have it any other way. The Polarchromic glass is key for changing light conditions when you are on the water all day. It's amazing to see how effective the polarizing qualities of the glass are at cutting down glare on a whole variety of water surfaces. These shades really bring the fishing experience to another level! I love them. Copper mirror or ignitor for trout fishing all day long.
(*edit: not a trout.... Payara from Bolivia)
