For sunglasses, I usually stick with classic tortoise New Wayfarers, but I'm thinking of getting these in the next week or two to have something that's a little more in your face.
Those are cool glasses, but you run the risk of looking awfully hipster-ish if you haven't got the right overall style and face shape to pull them off in a non-ironic way.
I need to get a new Rx soon and I'm thinking of getting one of the Warby Parker styles. Leaning toward these ones, but I've got 5 pairs on the way through their try-at-home thing. http://www.warbyparker.com/men/optic...londe-tortoise But for Rx sunglasses, I might just stick with Costco - I saw some decent-looking aviator frames there for something like $40, and getting the lenses there is usually pretty cheap ($50-70 IIRC).
@hornsup - for future reference, if you use the LEC online chat they'll usually price match if something you bought goes on sale within 2 weeks (not sure of the exact rules). Probably missed your chance for yesterday's sale, but you could still give it a try, nothing to lose!
