Lost black Ray-Ban sunglasses with green lenses and a scratch on the right lens left on a park bench in West Midlands.

I lost my favorite pair of Ray-Ban sunglasses in the West Midlands while visiting a park last Sunday. I remember taking them off to read, but when I got up to leave, I must have left them behind on the bench. They are black with green lenses and have a slight scratch on the right lens.
