He got closer than you might expect.
There's a guy on YouTube who makes things from scratch — he actually gathers the raw materials and figures out how to produce stuff without modern manufacturing processes. His name is Andy George and he runs a channel called How To Make Everything.
He recently decided to try eyeglasses.
From the video description: "With some guidance from Dr. Lewis Dartnell, I collected sand, limestone, and hardwood ashes to melt down into the glass. Then I figured out how to grind the lenses down to the correct curvature to match my prescription. I also made the frames for them out of a tree."
He didn't quite succeed in making functioning eyeglasses, but he got closer than you might expect.
