Optometrists, also known as doctors of optometry, or ODs, are the main providers of vision care. They examine people's eyes to diagnose vision problems, such as nearsightedness and farsightedness, and they test patients' depth and color perception and ability to focus and coordinate the eyes. Optometrists may prescribe eyeglasses or contact lenses, or they may provide other treatments, such as vision therapy or low-vision rehabilitation.
Optometrists also test for glaucoma and other eye diseases and diagnose conditions caused by systemic diseases such as diabetes and high blood pressure, referring patients to other health practitioners as needed. They prescribe medication to treat vision problems or eye diseases, and some provide preoperative and postoperative care to cataract patients, as well as to patients who have had corrective laser surgery. Like other physicians, optometrists encourage preventative measures by promoting nutrition and hygiene education to their patients to minimize the risk of eye disease.
Although most work in a general practice as a primary care optometrist, some optometrists prefer to specialize in a particular field, such as contact lenses, geriatrics, pediatrics, or vision therapy. As a result, an increasing number of optometrists are forming group practices in which each group member specializes in a specific area while still remaining a full scope practitioner. For example, an expert in low-vision rehabilitation may help legally blind patients by custom fitting them with a magnifying device that will enable them to read. Some may specialize in occupational vision, developing ways to protect workers' eyes from on-the-job strain or injury. Others may focus on sports vision, head trauma, or ocular disease and special testing. A few optometrists teach optometry, perform research, or consult.
Most optometrists are private practitioners who also handle the business aspects of running an office, such as developing a patient base, hiring employees, keeping paper and electronic records, and ordering equipment and supplies. Optometrists who operate franchise optical stores also may have some of these duties.
Optometrists should not be confused with ophthalmologists or dispensing opticians. Ophthalmologists are physicians who perform eye surgery, as well as diagnose and treat eye diseases and injuries. 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.
