These are vintage safety glasses from the 40s or 50s. The glass lenses are clear, they have a few scratches and a deposit of something on one lens that might be able to be cleaned off. The bendable ear wires are coated with a brown coating, and very comfortable and form fitting to wear. These are a great steampunk piece or would make a really good addition to your memorabilia collection. The mesh sides fold in and the arms fold out and around. One of the screens is a bit detached from one part of the frame, but does not affect the piece too much, (see the second photo) totally wearable.
