Vintage B & L Bausch & Lomb Fun-Vue 23 sunglasses w/case.   I would say for repair.   Good cleaning and lenses need buffing out and right side to much flexibility goes horizontally.   Being sold as is for repair or parts.   I don't clean items I leave the original Patina on it. I have other collectibles in my eBay store and feel free to take a look.  Once again thanks for taking a look.
