These handsome glasses are vintage circa 1970s. They are made by Carrera and their condition is very good. The sides of the frames are metal and the face portion feels like a type of plastic. They are marked Carrera on both sides and inside they are marked, Made in Austria, 5547, 90, 130, EP. There is also a 5547 molded into the plastic on the inside. They measure 6 x 2 1/4 inches in the front and the sides are 4 1/2 inches long. They lenses seem like they may have a slight perscription in them, although they are plastic and not glass, so I may be wrong about this. They are very light weight so are comfortable to wear, I think they are driving glasses.
