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.
By contrast an optometrist is not a medical doctor (MD) or doctor of osteopathic (DO) medicine. Optometrists are not licensed physicians and do not go to medical school. Instead they complete a four-. year course in optometry and receive a degree to practice optometry, not medicine.
