What is an Optometrist (OD)?
An optometrist, who holds a Doctor of Optometry (OD) degree, is a licensed healthcare professional dedicated to primary vision care. Their services range from conducting comprehensive eye exams to detecting vision abnormalities and certain eye diseases. Unlike medical doctors, optometrists attend a specialized, four-year graduate program in optometry after completing their undergraduate studies. This rigorous education provides them with the expertise to assess a patient's overall eye health, prescribe corrective lenses (glasses and contacts), and in many states, prescribe medications for eye conditions.
The Optometrist's Path to Becoming a Doctor
The journey to becoming a Doctor of Optometry involves several key steps:
- Pre-Optometry Education: A bachelor's degree is required, with a focus on science courses like biology, chemistry, and physics.
- Optometry School: This is a four-year, postgraduate program at a college of optometry, culminating in the OD degree. The curriculum includes advanced topics such as ocular anatomy, physiology, pharmacology, and clinical training.
- Licensing: After graduation, prospective optometrists must pass a national board examination and often state-specific exams to be licensed to practice. All states require licensing for optometrists to ensure they meet professional standards.
- Residency (Optional): Some optometrists pursue an optional one-year residency program to specialize in specific areas, such as ocular disease, pediatrics, or low vision rehabilitation. While not mandatory, it offers additional advanced clinical training.
Optometrist vs. Ophthalmologist: Understanding the Key Differences
The core distinction lies in their training and scope of practice. An ophthalmologist is a medical doctor (MD) or doctor of osteopathic medicine (DO) who has completed medical school and a lengthy residency, enabling them to perform eye surgery. Optometrists, while licensed to provide primary eye care and certain treatments, do not perform surgery.
Scope of Practice: The Role of an OD
Optometrists are often the first point of contact for patients regarding their vision. Their services typically include:
- Performing comprehensive eye exams and vision testing.
- Diagnosing and managing certain eye diseases and conditions, such as glaucoma, diabetic eye disease, and macular degeneration.
- Prescribing and fitting corrective lenses, including glasses and contact lenses.
- Prescribing medications for specific eye problems, like infections or dry eye.
- Providing pre- and post-operative care for patients undergoing eye surgery performed by an ophthalmologist.
Scope of Practice: The Role of an MD (Ophthalmologist)
Ophthalmologists offer a broader range of services due to their extensive medical and surgical training. Their capabilities include:
- All services provided by an optometrist.
- Performing advanced medical treatments for complex eye conditions.
- Performing eye surgery, such as cataract surgery, glaucoma surgery, and laser vision correction (LASIK).
- Diagnosing and treating more serious eye injuries and diseases.
- Conducting research on the causes and cures of eye diseases.
A Deeper Dive into Optometrist (OD) and Ophthalmologist (MD/DO) Roles
| Feature | Optometrist (OD) | Ophthalmologist (MD/DO) | Optician |
|---|---|---|---|
| Education | 4-year undergraduate + 4-year Doctor of Optometry (OD) program | 4-year undergraduate + 4-year Medical School (MD/DO) + Residency (3-4 years) + possible Fellowship | 1-2 year technical degree or on-the-job training |
| Surgical Procedures | No, does not perform surgery | Yes, performs all types of eye surgery | No, does not perform surgery or eye exams |
| Eye Exams | Yes, performs comprehensive exams | Yes, performs comprehensive exams | No, fills prescriptions from ODs or MDs |
| Prescribes Lenses | Yes, prescribes and fits glasses and contact lenses | Yes, prescribes and fits glasses and contact lenses | Yes, fits and dispenses eyewear based on prescriptions |
| Treats Eye Disease | Yes, diagnoses and manages many conditions with medication | Yes, diagnoses and treats all eye diseases and conditions | No, does not diagnose or treat eye diseases |
| Specialization | Can specialize in areas like pediatrics, low vision, or contact lenses | Can specialize in various areas like retina, glaucoma, or pediatrics | Can specialize in dispensing and fitting specific types of eyewear |
The Collaborative Nature of Eye Care
For many people, the optometrist serves as the primary eye care provider, much like a general practitioner for overall health. If an optometrist detects a more serious condition that requires surgical intervention or specialized medical treatment beyond their scope, they will refer the patient to an ophthalmologist. This collaborative approach ensures that patients receive the most appropriate and effective care for their specific needs.
The Role of the Optician
Completing the eye care trifecta is the optician. These are technicians who work with prescriptions provided by optometrists and ophthalmologists. They measure, fit, and dispense glasses and other corrective lenses. Unlike ODs and MDs, they do not perform eye exams or diagnose disease. Their expertise is crucial for ensuring that corrective eyewear is accurate, comfortable, and functional for the patient.
Why the Distinction Matters for Patients
Knowing the difference between these eye care professionals is essential for making informed healthcare decisions. For routine eye exams, vision correction needs, or managing common eye conditions, an optometrist is the appropriate choice. If you have a more complex issue, require surgery, or are referred by your optometrist, an ophthalmologist is the specialist you need. Misunderstanding these roles can lead to unnecessary delays in receiving the right treatment.

Conclusion: A Doctor is a Doctor, But Not All Doctors Are the Same
In short, is an OD considered a doctor? Yes, an optometrist is a doctor, having earned a Doctor of Optometry degree through extensive training. However, they are not a medical doctor and their expertise lies in primary vision care rather than surgery. The key takeaway for patients is that optometrists, ophthalmologists, and opticians all play vital, distinct roles in the eye care ecosystem. By understanding their respective qualifications and scopes of practice, you can ensure you are seeing the right professional for your eye health needs, from routine check-ups to complex medical or surgical interventions.
