metal spectacle frame

spectacle frame, metal

A structure in metal for enclosing or supporting ophthalmic lenses. Common materials include nickel/silver, Hi-nickel alloy, bronze, stainless steel, gold, gold plated, gold coating (commonly referred to as gold filled in which the base metal is most often nickel silver and for better quality frames, monel), copper, beryllium, titanium and sometimes aluminium. Metal spectacle frames are usually more rigid and maintain their shape better than plastic spectacle frames. However, the contacts with the skin of the nose and ears are done with plastic (or silicone) nose pads and temple covers.
