not sure what these were made for.........no markings no labels..........very well made though........very dark rectangular glasses......the plastic piece that holds onto your ears is screwed into the lense.........there is plastic protector on the inside but none on the outside..........only very light swirly marks on the outside seen under magnification and glare...nothing seen when looking thru the glasses.................has to be for welding or other work requiring eye protection from brightness..............these are new unused...........near perfect with exceptions noted............the last photo shows windex residue...............these appear to be us made...........send a message if you have questions.............
