DAKS sunglasses. They have prescription lenses. I purchased these on this site, but I didn't realize they were prescription. Therefore, I cannot answer any questions about the prescription. The lenses have a gradient that complements blouses, and the design is easy to wear. The frame is lovely, so you could consider replacing the lenses.
