Costa Frames and Lenses

[gasdad]

Do yourself a favor and get the 580 lenses ( made of real glass). They resist scratches much better than the 400 lenses (made of poly carbonate). the weight difference bs the 400 and 580's is negligible (most glass lenses are a bit heavier) I like the blue mirrored lenses but a lot of people like the green mirrored lenses--your preference I guess. I think you may get better depth perception when on the water with the blue. Frames are going to be a personal choice--you need to try a few pair on and see which ones fit your head, nose ears the best. Do not buy a pair without trying on different style frames first IMHO. I like the fathom frames because they fit my head well and I can wear them all day long without my ears or nose hurting.
