CONTACT LENSES
A contact lens is an artificial lens designed to fit over the cornea of the eye in order to correct vision.
The first contact lenses, invented in 1887 by Adolf Fick, were made of glass and were used to correct astigmatism.
It was not until the development of sophisticated optical instruments and plastic materials in 1948 that the modern-day contact lens was invented by Kevin Tuohy.
