According to the American Optometric Association [AOA], "Doctors of optometry (ODs) are the primary health care professionals for the eye. Optometrists examine, diagnose, treat, and manage diseases, injuries, and disorders of the visual system, the eye, and associated structures as well as identify related systemic conditions affecting the eye."
Today, the profession of optometry involves much more than just prescribing and fitting glasses and contact lenses. ODs are trained to evaluate any patient’s visual condition and to determine the best treatment for that condition. ODs are viewed increasingly as primary care providers for patients seeking ocular or visual care.
