I've had this idea in my head for some steam punk goggles/glasses using Zero Aperture iris diaphragms. And I think they would fit in perfectly with this specific style give them a look here -> [link] They're kinda expensive, but they would be soooooooooo awesome.
the only improvement I could think of would be to put two polarized lenses in each eye, and have them be adjustable for the amount of light you let in, but those are sweet!
Very nice! Instant Fav!
Also thaught of doing that before I decided to go with the "classic" construction... this time
I like!
great design!
