Optometrists, also known as doctors of optometry, are trained specialists who identify vision problems and disorders and abnormalities of the eye, and prescribe corrective lenses and aides for the visually impaired.
Optometrists provide most primary vision care. They examine people’s eyes to diagnose vision problems and eye diseases, and they test patients’ visual acuity, depth and colour perception, and ability to focus and coordinate the eyes.
Optometrists prescribe eyeglasses and contact lenses and provide vision therapy and low-vision rehabilitation.
Optometrists analyse test results and develop a treatment plan. They administer drugs to patients to aid in the diagnosis of vision problems and prescribe drugs to treat some eye diseases.
Optometrists often provide preoperative and postoperative care to cataract patients, as well as to patients who have had laser vision correction or other eye surgery.
As part of the optometrist job description they diagnose conditions caused by systemic diseases such as diabetes and high blood pressure, referring patients to other health practitioners as needed.
