got scrip glasses from riderseyewear right in florida. do you need scrip?
i found that when i wore contacts it was hard to find the right pair of glasses for all conditions--must have 8 pairs of no prescription glasses for the bike. lots of it is trial and error.
if you do a forum search under glasses you might find some good info and maybe even something about the Costa Del Mars.
