When it comes to your eye care, there are several different professionals to help you: opticians, optometrists, and ophthalmologists. But which is which? Who does what? Why do you need all three? Here’s a quick guide to the 3 O’s of eye care.


Opticians are trained technicians who design, fit and dispense eyeglass lenses and frames, contact lenses, and other devices that correct vision. Opticians attend a 2 year opticianry program before taking their national boards to obtain licensure.


Optometrists are healthcare professionals who provide primary vision care. An optometrist earns a doctor of optometry (O.D.) degree by completing a 4 year graduate program – they are not medical doctors and do not attend medical school. The scope of optometry includes performing eye exams and vision tests, prescribing corrective lenses (glasses and contacts), detecting eye abnormalities, and managing/prescribing medications for various eye diseases.


Ophthalmologists are medical doctors who attend medical school and specialize in the eye and vision care (Eye M.D.). Ophthalmologists are licensed to practice medicine and surgery, in addition to prescribing and fitting corrective lenses for vision problems.

All three of these eye care professionals have a continued education requirement to maintain their license and keep their knowledge up to date.
