Black Ray-Ban style glasses with engraving

I lost my black Ray-Ban style glasses yesterday around 3pm outside Clarkson University student center on Market Street in Potsdam. They’re square-ish plastic frames with a glossy finish, and there’s a tiny scratch on the upper rim of the right temple. Inside the left temple sits engraved initials 'KM'. I came with a gray microfiber sleeve, and there’s a small campus logo sticker on the sleeve. I really need them back—these are my daily glasses for reading and driving, and I’ve worn them since last fall. If anyone finds them, I’d be grateful to get them back; I can meet you near the student center or at the bookstore.
