So you’ve heard about getting glasses in under an hour, but what if you could make them at home? The technology is getting to the point that not only can you print the frames, but 3D print a lens as well. You broke a lens, print a replacement. In a 3rd world country without an optics lab, no worries, you just need a 3D printer. This gives new meaning to “3D glasses”! Speaking of 3D glasses, maybe NFL player Ziggy Ansah of the Detroit Lions can 3D print himself a better pair!
