Victorian Aqua SUNGLASSES 1800’s

Invented by James Ayscough an English optician, He tinted his lenses green or blue because he thought it would improve vision. As you can see, they have foldable frames with little round loops at the ends to attach some type of cord or chain. In pretty good condition seeing as they’re about 150+ years old. They look steam punk ! Being sold as is as found as seen in the pictures. Thanks for looking.
