You are viewing a nice Victorian era lorgnette eye glasses. The glasses measure 3 1/2" long by 1" at their widest part. They are 5 1/4" long when opened. The lens measure 32 mm by 23 mm. They have nice hand engraved designs. To open take your finger and pull out the bead at the top of the lens.. They lock when you close them. They are well made.
