An optometrist (O.D.) is an independent health care professional who is specifically educated, clinically trained, and licensed to examine, diagnose, and treat conditions or impairments of the eye and human vision system, prescribe eyeglasses and contact lenses, and prescribe medications.

An optician fits, supplies, and adjusts eyeglasses and contact lenses. An optician cannot examine the eyes or prescribe eyeglasses or medications.
