It's funny how machines of the past makes you look like the robots of today. This thing, as cute as it is, is called a phoropter or refractor, its an ophthalmic testing device.
If you have ever been to the eye doctor, this is the thing they test you with at the end, flipping between two filthy lenses, is one better, or two? Then they flip, and they basically look the same. And you can't tell the difference so they add a third choice. But all the lenses are dirty, so you can't tell if its the dirt or your eyes. And in the end you just hope they make it right.
