Contact lenses were first proposed by Leonardo Da Vinci in 1508.
Leonardo da Vinci is frequently credited with introducing the idea of contact lenses in 1508. The famous Italian architect, mathematician and inventor Leonardo da Vinci described a method of directly altering corneal power by either submerging the head in a bowl of water, or wearing a water-filled glass hemisphere over the eye. He did not suggest his idea be used for correcting vision, being more interested in learning about the mechanisms of accommodation of the eye. Many believe da Vinci's ideas eventually led to the development of contact lenses more than 350 years afterwards.
In 1827, English astronomer Sir John Herschel proposed the idea of making a mold of a person's eyes. Such molds would enable the production of corrective lenses that could conform to the front surface of the eye. But it was more than 50 years later that someone actually produced such lenses, and there is some controversy about who did it first.
Some reports say German glassblower F.A. Muller used Herschel's ideas to create the first known glass contact lens in 1887. Other reports say Swiss physician Adolf E. Fick and Paris optician Edouard Kalt created and fitted the first glass contact lenses to correct vision problems in 1888.
