Adolf Fick's 15mm-thick Glass Contact Lenses
Adolf Fick's first successful contact lenses were vastly different from the contacts we have today. He began experimenting with his "contact spectacles" on the eyes of rabbits and corpses before making a successful lens. They were likely very painful, and you could only wear them for a few hours at a time. The lens were made of glass, measured 8-15mm thick, and were scleral, which means that they fit on the white part of the eye.
