Ray-Ban Wayfarer glasses in black matte frames

I lost my Ray-Ban Wayfarer glasses yesterday around 3pm in Cambridge outside the Grand Arcade on Market Street near Market Square. They are black matte Wayfarers with a small silver Ray-Ban logo on the temples and a tiny scratch on the lower left lens; they came in a red leather case with a blue microfiber cloth. I think I left them on a bench near the entrance after grabbing a quick coffee, and I've been anxious ever since—these are my daily glasses and were a gift from my grandmother, so I’d really appreciate getting them back.
