Contact lenses are tiny removable lenses that are worn in contact with the eye. 1508, Leonardo da Vinci was envisioned and later René Descartes around 1636-1637.
But in 1887, German physiologist Adolf Eugen Fick was invented and made. He first fitted animals with the lenses, and later made them for people. These lenses were made from heavy brown glass and were 18-21mm in diameter. The lenses were improved by August Muller in 1889; he made lenses that corrected myopia (nearsightedness).
1948, the first plastic contact lenses were made by California optician Kevin Tuohy. Soft contact lenses (hydrophilic lenses) and gas-permeable lenses (which let oxygen pass through the lens and to the cornea) were invented in the 1970s.
