Contact lenses are a medical device that are worn on the surface of the eye. Just like with glasses, a contact lens prescription is different for each person and is based on the size and shape of your eye. The prescription also includes the base curve, which is the curve on the back of the lens that rests against your eye, and the diameter, which is the width of the lens. In the United States, contact lenses are regulated by the Food and Drug Administration (FDA) as medical devices.
Contact lenses are safe and effective when used as directed. However, because contact lenses are a medical device, there are potential risks associated with their use. These risks can be minimized by following the instructions of your eye care professional and by having regular contact lens exams.
How often you need a contact lens exam depends on several factors, including your age, the type of contact lenses you wear, and your overall health. Children and adults who wear contact lenses should have a contact lens exam at least once a year. People who have certain health conditions, such as diabetes, may need to have more frequent contact lens exams.
Your eye care professional will determine how often you need a contact lens exam based on your individual needs. Be sure to follow your eye care professional's recommendations to help keep your eyes healthy.
