What Are Contact Lenses?

Contact lenses are clear, plastic discs used to correct the same conditions that eyeglasses do, like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism (blurred vision due to the shape of the cornea). Today contact lenses provide clear vision to more than 37 million Americans, and nearly 120 million people worldwide.

The History of Contact Lenses

Though they might seem like a recent phenomenon, contact lenses actually go back a long way. In 1508, Leonardo da Vinci first suggested that the optics of the human eye could be altered by placing the cornea directly in contact with water. It wasn’t until centuries later, in the late 1800s, that his theory was evolved into a practical lens design.
