Serious Question: Sunglasses advice!

[LargeCents]

I played in my first tournament last night. I have only played online poker so far, besides a few dorm room games in college. I've ween watching the WPT, and all of the TV poker that I can stand, and notice the typical strategy of wearing sunglasses and hats, etc. I like the idea, and want to have sunglasses at least as an option, to play around with, to see if I like to use them.

Well, last night, I brought my driving sunglasses, and put them on a few times, just too get a feel. But, I hated wearing them because it wasn't really all that bright in "card room" to begin with. I had a hard time telling the colors of my chips, etc. I obviously had a pair of sunglasses that weren't optimal.

My question is this: What kind of sunglasses do any of you guys recommend? Is there a few brands that the pros swear by? Is there a certain tint factor or anything that I should consider when buying them? I think my personal comfort and style is the main factor for me. But, I want to see the damn cards also. I know, I know, I should take a few poker chips, and a deck of cards along when I shop for sunglasses. But, I figured I'd troll around on here to get some insight.

Thanks,
