That's neat! I was thinking of getting some at some point because I wear a lot of vintage/costume clothes and I hate wearing contact lenses. Do they make them a bit bigger than the 18thc ones they model them from? I have some Victorian tinted glasses but they're tiny (like most 18th/19thc clothes and furniture, too!).
(These historians who say, 'actually, people weren't much smaller then than they are now' are talking utter bollocks! I defy them to find a Victorian top hat that fits or an 18thc chair they can sit on comfortably!)
