Black Ray-Ban Wayfarer glasses

I lost my black Ray-Ban Wayfarer glasses yesterday around 3pm, near Mission Plaza during the farmers market on Higuera Street in San Luis Obispo. Frame is matte black, slightly rounded square, with a Ray-Ban logo on the temples. There’s a small scratch on the right lens and an engraving 'P.Patel' on the inside of the left temple. They came with a navy blue soft case with a red interior, initials 'PP' on the case. They’re prescription lenses and mean a lot to me—it was a gift from my grandmother, and I’m really hoping someone picked them up and can return them.
