Black Ray-Ban glasses with gold hinges

I lost my black Ray-Ban eyeglasses yesterday around 3pm while walking from Riverfront Park toward downtown Spokane. They're black acetate, rectangular frames, about medium size, with faint gold hinges and lenses that have a few micro-scratches. There's a tiny etching 'AZ' on the inside of the left temple and a small green heart sticker near the nose bridge. They were a gift from my sister and I can't see well without them, so I’d really appreciate any help in getting them back—if you spot them, DM me here or email [email protected].
