Contact Lenses

Leonardo da Vinci introduced the idea of contact lenses in his 1508, wherein he described a method of directly altering corneal power by wearing a water-filled glass hemisphere over the eye. In 1888, German ophthalmologist Adolf Gaston Eugen Fick constructed and fitted the first successful contact lens. These were large scleral lenses, which rested on the less sensitive rim of tissue around the cornea and were made from heavy blown glass.
