Yes.
An optometrist is a doctor of optometry: a clinician who holds a four-year doctoral-level degree, is licensed in every state before they practice, and is classified as a physician for Medicare purposes within their state scope.
An optometrist is not a medical doctor, and the O.D. path does not run through medical school.
Is an optometrist a doctor?
Yes.
An optometrist is a doctor of optometry — the profession's degree is the Doctor of Optometry (O.D.), a 4-year graduate program, and every state requires optometrists to hold a license before they practice.
The word "doctor" carries two senses, and the confusion lives in the gap between them.
One sense is academic: a doctorate, a graduate degree earned after years of university study.
The other is clinical: a physician.
An optometrist holds the first for certain; whether the second applies is the question the rest of this page answers.
The clinical scope is real either way.
BLS lists diagnosing refractive errors and eye diseases such as glaucoma, prescribing glasses, contact lenses and medication, and minor surgical procedures among an optometrist's typical duties — with the procedures and drugs always as state law permits.
Even the informal phrase "eye doctor" spans more than one profession; the degree letters — O.D. versus M.D. — are what distinguish them.
This page is the professional-status question: what the O.D. is, how federal law classifies it, whether the "Dr." title fits, and where the degree differs from the M.D.
For the work itself, the optometrist career guide covers the role, its settings and its training path.
Is an OD a medical doctor?
No. An optometrist does not hold an M.D. and does not go to medical school.
BLS puts the two paths side by side: physicians complete a bachelor's degree, 4 years of medical school and then 3 to 9 years of internship and residency depending on specialty, while optometrists complete a 4-year O.D. program with an optional 1-year residency.
Ophthalmologists are the physicians of eye care.
BLS distinguishes ophthalmologists from optometrists and describes them as physicians who also perform a wider range of surgeries; their treatment of eye disease may include surgery to correct vision problems or prevent vision loss from glaucoma and other diseases.
Prescribing shows the boundary in practice.
All states allow optometrists to prescribe medication, but states vary in which medications an O.D. may prescribe and in whether optometrists may perform surgery or other procedures such as vaccinations.
Where each state draws that line is the scope-of-practice question, and state law decides it.
So the honest answer has two halves: an O.D. is a doctor — of optometry — and is not a medical doctor.
The distinction follows the optometrist into any setting: inside an ophthalmology group, an optometrist is still an optometrist, practicing under the scope their own state grants them.
What does Medicare classify ODs as?
As a physician — with the limits written into the statute.
Under Social Security Act section 1861(r)(4), a doctor of optometry counts as a "physician" for Medicare purposes.
The statute applies that label only for its defined purposes, and only to services the O.D. is legally authorized to perform as a doctor of optometry by the state where they practice.
The classification has been in place since April 1, 1987, and it covers the services an optometrist is authorized to perform under state law or regulation, where those services are reasonable and necessary.
The federal Stark self-referral law defines "physicians" to include optometrists as well — a point both National Vision's and Warby Parker's FY2025 annual reports spell out when they describe the law's effect on their businesses.
Read together, the federal layers say one thing: Medicare treats O.D.s as physicians within their state scope.
The classification rides on top of a state license — it is not itself a license, and it does not make an optometrist a medical doctor.
For a career, the classification matters most where medical-model care and credentialing paperwork meet: hospitals, O.D.-M.D. groups and practices serving Medicare patients.
What any payer pays for a specific service is a separate, practice-level question that the practice's billing operation handles under CMS rules.
A federal classification, not a license
Can optometrists use the title Dr.?
The degree carries the answer in its name: Doctor of Optometry.
BLS describes it as the degree optometrists typically need — 4 years, entered after at least three years of undergraduate education.
On a name badge, a schedule or a signature line, O.D. is the credential that marks a licensed doctor of optometry, just as M.D. marks a physician.
Two title questions deserve care, though.
First, "Dr." on its own does not say which kind of doctor — the degree letters and the state license do that, and Medicare's physician classification is a federal statute category, not a degree.
Second, passing the national licensing exams is not board certification.
NBEO's own guidance makes that point: passing its exam and holding its certificate is not board certification, and candidates who want board certification apply to the American Board of Optometry for it.
Board certification is voluntary and separate from the state license.
One thing our research did not establish: state-by-state rules on using "Dr." in advertising, signage or patient materials.
The place this gets settled is state law.
If you are an optometrist putting the title on an ad, a website or a practice sign, confirm the rules with your state board of optometry first.
How is the OD degree different from an MD?
Both are doctoral paths; they differ in the school, the required post-graduate training and what each license covers.
BLS's side-by-side:
| Optometrist (O.D.) | Physician (M.D.) | |
|---|---|---|
| Entry | At least 3 years of undergraduate education; applicants typically hold a bachelor's degree. | Typically a bachelor's degree. |
| Program | A 4-year O.D. program, entered through an exam covering natural sciences, reading comprehension, physics and quantitative reasoning. | 4 years of medical school. |
| After the degree | An optional 1-year residency, in areas such as primary care, cornea and contact lenses, and ocular disease. | 3 to 9 years of internship and residency depending on specialty, with 1 to 3 more years for a fellowship. |
| The eye care work | Diagnose refractive errors and eye diseases such as glaucoma; prescribe glasses, contacts and medication; minor procedures as state law permits. | Ophthalmologists diagnose and treat eye conditions, and treatment may include surgery. |
One caution on the comparison: BLS's 3-to-9-year residency range covers physicians as a whole, and BLS does not give a residency length for ophthalmology specifically.
The O.D. path is shorter and optometry-specific; the M.D. path is longer, and its residency years are required rather than optional, because the physician path BLS describes depends on them.
What both paths end in is a license to practice.
For optometrists, every state requires one: an accredited O.D. plus all sections of a qualifying exam, along with continuing education and periodic renewal — and where a state adds one, an additional exam such as on clinical skills or on optometry law.
Why it matters for your career
If you are applying to optometry school, the label describes exactly what you are signing up for: a four-year doctoral program with its own entrance exam, its own schools and its own state licenses — graduate study in eye care, not medical school.
If you are already an O.D., the status question follows you into hiring and practice settings.
What "doctor" lets you do in the exam room is set by your state's scope law — every state allows prescribing, and your state decides the rest — so the title travels with you while the authority is set per state.
If you work alongside optometrists as a technician, an optician or an office coordinator, the credential shorthand tells the licenses apart in O.D.-M.D. groups: O.D. for the doctor of optometry, M.D. for the physician.
And if you are weighing optometry against medical school, weigh the whole path rather than the title alone.
The degree, the residency decision, the scope your state grants and the settings you want all flow from that choice.
