Contact lenses are thin, clear disc-shaped plastic lenses that are placed on top of the eye’s surface to correct poor vision. While vision correction is the main use for contacts, some people wear non-prescription colored contacts to enhance or change their eye color.

Vision conditions like nearsightedness, farsightedness, astigmatism and presbyopia can be corrected with contact lenses. An eye doctor must write a prescription for you to get and wear prescription contacts, just like you need to get corrective eyeglasses.

There are different types of contact lenses to fit different vision needs, personal preferences and lifestyles. Read more to learn the types and history of contact lenses, and how to determine which contacts are best for you.
