What Is the Difference Between an Optometrist, an Ophthalmologist and an Optician?

Optometrists are primary eye-care providers, which can be thought of in the same way as the family doctor is the primary health care provider. Optometrists are required to complete four years in optometry school following at least three years in a university science program, and are licensed by the College of Optometrists to evaluate, diagnose, and treat disorders of the eye and visual system. 

Ophthalmologists are medical doctors who have completed specialized residency training in the study, diagnosis, and treatment of eye diseases. They are secondary health care providers and often treat eye diseases through the use of drugs and/or surgery. Someone who requires the services of an ophthalmologist would usually require a referral from an optometrist or family doctor.

Opticians are trained through a college program to fabricate and fit vision aids based on the prescription of an optometrist or ophthalmologist. Opticians are licensed to provide spectacles and they may fit and dispense contact lenses and other optical aids. They do not assess, diagnose or treat eye conditions, nor can they write prescriptions for eyeglasses or contact lenses.
