Spectacles with silver frame and polished round lenses

Forehead spectacles with a silver frame, a spoon attached to the bridge between the lenses, and ground round lenses. Model: in the middle of the arched bridge, ending in a curl on the rim around the lens, a pin is attached that secures the spoon to the spectacles. The spoon has a hinge halfway. The rims around the lenses are open at the top and bent back to form a hook around which a metal wire is stretched for closure.
