I'm definitely interested in what you end up doing, too, Sharon. Especially if you end up having good luck somewhere local in Tucson. I definitely need to invest in some Rx sunglasses, I'd like for them to be athletic oriented (rather than just throwing tinted lenses in any ol' frame), and I didn't really care for the (limited) selection at my regular optometrist's office (other than some $500+ Maui Jims, which weren't in the budget) when I checked a few months back. I don't have bifocal needs, but I do have a moderately-strong prescription that I know will limit my wrap-around choices.
