Optometrists are healthcare professionals who provide primary vision care ranging from sight testing and correction to the diagnosis, treatment, and management of vision changes. An optometrist is not a medical doctor. An optometrist receives a doctor of optometry (OD) degree after completing four years of optometry school, preceded by three years or more years of college. They are licensed to practice optometry, which primarily involves performing eye exams and vision tests, prescribing and dispensing corrective lenses, detecting certain eye abnormalities, and prescribing medications for certain eye diseases.
An ophthalmologist is a medical doctor (MD) or an osteopathic doctor (DO) who specializes in eye and vision care. Ophthalmologists are trained to perform eye exams, diagnose and treat disease, prescribe medications and perform eye surgery. They also write prescriptions for eyeglasses and contact lenses.
According to the College of Optometrists in Vision Development (COVD), one study indicates 13% of children between the ages of 9 and 13 suffer from moderate to severe convergence insufficiency (an eye teaming problem that can affect reading performance), and as many as one in four school-age children may have at least one learning-related vision problem.
