They analyze test results and develop a treatment plan. Optometrists prescribe eyeglasses, contact lenses, vision therapy, and low vision aids. Optometrists often provide postoperative care to cataract patients. When optometrists diagnose conditions that require care beyond the optometry scope of practice such as diabetes or high blood pressure, they refer patients to other health practitioners. Optometrists should not be confused with ophthalmologists or dispensing opticians.
Ophthalmologists are physicians who diagnose and treat eye diseases and injuries.
They perform surgery and prescribe drugs. Like optometrists, they also examine eyes and prescribe eyeglasses and contact lenses. Dispensing opticians fit and adjust eyeglasses and in some states may fit contact lenses according to prescriptions written by ophthalmologists or optometrists. Optometrists provide most of the primary vision care people need. What to Expect A thorough vision examination given by your doctor of optometry may take 30 minutes to an hour.
