My mother has hopped on this trend (she had them back in the 80s as well). She found two pairs at TJ Maxx, a glossy black pair and a matter pair that folds (sounds tacky, but they are actually cool, you can't see the seams where they fold unless you really look). IIRC they were $40 each. I used to have a pair as well but since my perscription is so strong now I don't generally get lenses for sunglasses.
