1. What Is Optometry and What Do Optometrists Do?
Optometry is a healthcare profession focused on examining, diagnosing, treating, and managing diseases and disorders of the eye and visual system. Doctors of Optometry (ODs), or optometrists, are primary eye healthcare providers who play a crucial role in maintaining overall health and well-being. They are recognized as physicians under Medicare.
What Optometrists Do:
- Perform comprehensive eye exams to assess visual acuity and eye health.
- Diagnose and manage eye diseases and conditions such as glaucoma, macular degeneration, and cataracts.
- Prescribe eyeglasses, contact lenses, and medications to correct vision problems and treat eye conditions.
- Provide low vision rehabilitation and vision therapy services.
- Counsel patients on surgical and non-surgical options to meet their visual needs.
- Detect systemic diseases, such as diabetes and high blood pressure, through eye exams.

2. What Education and Training Do Optometrists Have?
Optometrists complete extensive education and training to provide comprehensive eye and vision care.
Education and Training of Optometrists:
-
Pre-Professional Undergraduate Education: Optometrists typically complete a bachelor’s degree at a college or university, with a focus on science courses such as biology, chemistry, and physics.
-
Doctor of Optometry (OD) Degree: After completing their undergraduate education, aspiring optometrists attend a four-year professional program at a college of optometry. This program includes coursework in anatomy, physiology, optics, pharmacology, and clinical practice.
-
Residency Programs (Optional): Some optometrists choose to complete an additional residency in a specific area of practice, such as:
- Primary Eye Care: Focuses on comprehensive eye exams and the management of common eye conditions.
- Geriatric Optometry: Specializes in the eye care needs of older adults.
- Pediatric Optometry: Focuses on the eye care needs of children.
- Vision Therapy and Rehabilitation: Provides treatment for visual disorders that affect learning, development, and daily life.

-
Licensure: After completing their education and training, optometrists must pass a national board examination and obtain a license to practice optometry in their state or jurisdiction.
3. Why is Optometry Important for Overall Health?
Optometry plays a crucial role in maintaining overall health because eye exams can detect not only vision problems but also signs of systemic diseases.
How Optometry Contributes to Overall Health:
- Early Detection of Systemic Diseases: During a comprehensive eye exam, an optometrist can identify signs of systemic diseases such as diabetes, high blood pressure, autoimmune diseases, and cancers. For example, optometrists identified signs of diabetes in over 301,000 patients who did not know they had the condition in 2018 alone, according to the American Optometric Association.
- Management of Ocular Manifestations of Systemic Diseases: Many systemic diseases can affect the eyes and vision. Optometrists can diagnose, treat, and manage these ocular manifestations to prevent vision loss and improve overall health.
- Preventive Care: Regular eye exams are an important part of preventive care. They can help detect eye diseases and conditions early, when they are most treatable.
- Improved Quality of Life: Good vision is essential for many aspects of daily life, including work, school, and recreation. Optometry helps improve quality of life by correcting vision problems and managing eye diseases.
