Explore Optometry. Home / Education / Admissions / Explore Optometry. A Doctor of Optometry (OD) is an independent, primary health care provider who examines the visual system, the eye and associated structures, as well as diagnoses, treats and manages related diseases and disorders. Optometry involves much more than prescribing and fitting glasses and contact lenses.
All are eye care professionals, but only an ophthalmologist is a medically trained specialist. Optometrists examine eyes, give advice on visual problems, and prescribe and fit glasses or contact lenses. If eye disease is detected, an optometrist will refer patients to an ophthalmologist for further management. In certain circumstances, ophthalmologists and optometrists work collaboratively in the care of patients, especially those with chronic eye diseases. 5 years at university leading to a degree in optometry.
