An alternative to eyeglasses, contact lenses are widely used across the globe. Contact lenses provide the inconspicuous clarity many people desire, and the wide array of materials used to make lenses coupled with the assortment of styles of contact lenses have helped to make them more comfortable than ever before.

It may seem like contact lenses are a relatively recent invention, but they’ve actually been around far longer than one would think. As far back as 1508, Leonardo da Vinci illustrated the concept of contact lenses. Three hundred years later a British astronomer named Sir John Herschel conceptualized the practical lens design. First designs of contact lenses covered the entire eye and were made from glass. By 1948, plastic contact lenses came on the scene and were designed to cover only the eye’s cornea. Through the 20th century, contacts continued to evolve. It is believed that now more than 30 million people in the United States alone wear contact lenses. Two-thirds of those wearers are female, says the Centers for Disease Control and Prevention.
