An optometrist is an eye doctor who has earned the Doctor of Optometry (OD) degree. Optometrists examine eyes for both vision and health problems, and correct refractive errors by prescribing eyeglasses and contact lenses. Some optometrists also provide low vision care and vision therapy.

Optometrists in the United States also are licensed to prescribe medications to treat certain eye problems and diseases. The scope of medical care that can be provided by optometrists is determined by state law. (For details about the scope of practice of optometrists where you live, visit the website of your state’s board of optometry.)
