When you think about inventions that have radically1 changed human existence, what comes to mind? Probably the wheel, the printing press, maybe the refrigerator and definitely personal computers. Then there are those more mundane2 things that we rarely think about, but without which we'd be much worse off. Like eyeglasses, for example. Imagine a world without glasses--many of us would walk around bumping into things and driving our cars up onto the sidewalk. So who invented glasses, and how were they first made? The truth is that nobody knows who invented eyeglasses. At some point in Italy between 1268 and 1289 someone came up with the idea, but the actual inventor remains3 anonymous4. What we do know is that the earliest lenses were made from quartz5 and were usually set into bone, metal, or leather. As soon as early opticians figured out how to make glass without bubbles and other obstructions6, they started making lenses out of glass.
