good sunglasses?

[speck-chaser]

Looking for some good glasses to wear while fishing. I always seem to get headaches from wearing glasses all day fishing. Ive never really tried the higher ends because I didnt want to spend the money and end up still with the headaches. The only Pair Ive worn for a good while w/o headaches,is a pair my mom gave me from hawaii,called maui jims,but they are a little dressy to wear fishing. My brother in law just bought a pair of wiley x. Anyone know anything about these? Supposed to be military specs and supposed to be great. Ive heard lots of you rave about the costas too. Just wondering what yalls thoughts are. tanx
