Regardless of style or brand Jason , remember the following and this is based upon 10 yrs of fly fishing guiding experience where your eyes are everything:
For stream trout fishing:
Colors: Amber, or Copper......copper is my favorite. Designed to bring out the contrast of a rocky stream bottom.
Lenses: DO NOT WASTE YOUR MONEY ON POLYCARBONATE LENSES!! No matter how tough they say they are GET GLASS LENSES. Optically correct glass lenses. They are a bit heavier but so much more durable than plastic it's stupid. I wasted plenty of money on supposedly 'Quality" poly lenses. They are more SHATTER resistant, but not nearly as SCRATCH resistant. Trust me you will scratch the crap out of them well before you'd ever shatter a lens. If someone is shooting a 12ga. at you while you are fishing I recommend the Poly, but if not.....GLASS
Glass is also optically better.....I also don't care what they say in their ads, I have had plenty of VERY good and very expensive Poly lens glasses and most will give me a headache because they aren't opically as good as quality glass. When you are wearing them for 12 hrs a day I want something that isn't straining my eyes even slightly.
Brands: Action Optics, Orvis , Costa Del Mar. These are the ones I trust and have used.
Orvis probably has the best warranty in the industry. I broke 2 pairs through negligence and they replaced them no questions asked within days.
Make sure they have a good warranty, a good at least semi-wrap design, and GLASS lenses. Stay away from dark grey or brown lenses. When it gets low light you might as well put em in your pocket.
Trust me.........for PA stream trout ......COPPER lenses.
Oh and quit it with the shiny frames and mirrored lenses, you trying to sneak up on a trout or some chick after the fishing day is over?
Dark frames will reduce the reflections into the sides of your eyes, and non mirrored will help you to not reflect into the trout's eyes.
You fishin' or fashion? You can get a cool pair of polarized sunglasses , or a fishing tool that can look cool.
Cripes I even make sure I have a hat with a dark underbrim to cut as much glare as possible.
