A contact lens is a medical device that requires a prescription
A contact lens is a medical device and can be worn to correct vision, as well as for cosmetic or therapeutic reasons. In the United States, all contact lenses, even purely cosmetic ones, require a prescription. They must be properly fitted and prescribed by an Eye Care Professional. An eye examination is needed to determine an individual’s suitability for contact lenses. This typically includes a refraction to determine the proper power of the lens and an assessment of the health of the eye. Prescriptions for contact lenses and glasses may be similar, but are not interchangeable. Contact lens prescriptions generally expire on a yearly basis, unless otherwise determined by your eye doctor. Seeing your eye doctor regularly for a comprehensive eye exam will not only assess your vision and need for updated prescriptions, but it may also help identify and lead to a diagnosis of other health concerns such as hypertension and diabetes.

Also, contact your Eye Care Professional with questions about proper lens use and for any other eye health concerns.
