Imperial optical 50s USA Imperial Thank you for viewing. This is a 50s American-made Imperial optical. I purchased and used it about 3 years ago, but there are cracks due to deterioration. There is also rust on the screws, but it does not interfere with wearing. Size Lens width: Vertical and horizontal, approximately 40mm Nose width: Approximately 22mm Frame width: Approximately 113mm Temple: Approximately 115mm Non-prescription clear lenses are installed. As this is a piece from over half a century ago, please consider purchasing only if you understand its age and condition. I am open to some price negotiation, so please feel free to ask!
