Black Wayfarer-style glasses near Tate Modern

I lost my black Wayfarer-style glasses yesterday around 3pm near the Tate Modern on Bankside. They’re Ray-Ban with prescription lenses, and there’s a tiny scratch on the bottom edge of the left lens plus a silver RB engraving on the inside of the right temple. The frame is intact aside from that scratch and the case is a black leather pouch with a red lining that I usually keep them in. They’re my go-to reading glasses and they have sentimental value because I got them as a gift from my sister. If anyone found them, please message me – I’d be so grateful to get them back.
