As primary eye care providers, doctors of optometry examine, diagnose, treat and manage diseases and disorders of the visual system, the eyes and associated structures as well as diagnose related systemic conditions.
Optometrists examine the internal and external structure of the eyes to diagnose eye diseases like glaucoma, cataracts and retinal disorders; systemic diseases like hypertension and diabetes; and vision conditions like nearsightedness, farsightedness, astigmatism and presbyopia. They also determine the patient's ability to focus and coordinate the eyes, to judge depth and to see color accurately.
They prescribe eyeglasses and contact lenses, low vision aids, vision therapy and medications to treat eye diseases as well as perform certain surgical procedures.
Optometrists work in private practices, multidisciplinary medical practices, hospitals, teaching institutions, research positions, community health centers and the ophthalmic industry, while others choose careers in the military, public health or government service.
