Optometrists treat vision problems and eye diseases. They use instruments and observation to examine eye health. They test patients' vision as well as depth and color perception. Next, optometrists test the ability to focus and coordinate the eyes. Finally, they analyze test results and create a treatment plan.
Optometrists prescribe eyeglasses, contract lenses, and vision therapy.
They prescribe treatment to preserve, restore, and improve vision. Optometrists may use drugs to examine eyes. In some states, they may also use drugs to treat eye disorders. Optometrists use computerized instruments to make diagnoses. These instruments allow technicians to do some of the tests that previously were performed by optometrists.
