All Medical Careers

1. Role Overview & Clinical Scope of Practice

Optometrists (O.D.s) deliver the vast majority of primary vision and medical eye care in the United States. During a comprehensive eye examination, optometrists assess refractive error (nearsightedness, farsightedness, astigmatism, and presbyopia), binocular vision and accommodation, intraocular pressure, and anterior and posterior segment ocular health using slit-lamp biomicroscopy, optical coherence tomography (OCT), and dilated retinal fundus photography.

Modern optometric scope of practice extends far beyond prescribing eyeglasses and contact lenses. In all 50 states, optometrists hold therapeutic pharmaceutical agent (TPA) authority to prescribe topical and oral medications—including antibiotics, antivirals, corticosteroids, immunomodulators, and glaucoma hypotensive drops—to treat ocular infections, uveitis, glaucoma, and corneal injuries.

Furthermore, optometrists remove superficial corneal foreign bodies, co-manage pre- and post-operative cataract and LASIK refractive surgery patients alongside ophthalmologists, and in an expanding number of states (10+ states) are licensed to perform anterior segment laser procedures (such as YAG laser capsulotomy and selective laser trabeculoplasty).

2. Core Clinical & Technical Responsibilities

In daily clinical practice, a Optometrist performs the following core responsibilities:

• Perform comprehensive refractive, binocular vision, and dilated ocular health examinations using phoropters, slit lamps, tonometers, and retinal OCT scanners.
• Diagnose and medically manage acute and chronic eye diseases, including open-angle glaucoma, diabetic retinopathy, macular degeneration, and infectious keratitis.
• Prescribe topical and oral therapeutic pharmaceutical agents (TPAs), corrective eyeglasses, scleral/specialty contact lenses, and low-vision rehabilitation devices.
• Remove corneal foreign bodies, insert punctal plugs for dry eye syndrome, and perform minor eyelid procedures as authorized by state optometric practice acts.
• Detect systemic diseases that manifest in the retinal vasculature—such as hypertension, diabetes mellitus, multiple sclerosis, and intracranial hypertension—and coordinate physician referrals.
• Co-manage pre- and post-operative care for cataract extraction, corneal transplants, and laser refractive surgeries.

3. Education Requirements & Accredited Schools

Prospective optometrists earn a four-year Doctor of Optometry (O.D.) degree from one of the 24+ U.S. colleges of optometry accredited by the Accreditation Council on Optometric Education (ACOE). Admission requires a bachelor’s degree with pre-medical coursework in biology, general and organic chemistry, physics, microbiology, calculus, and anatomy, plus a competitive score on the Optometry Admission Test (OAT).

The four-year O.D. program combines rigorous biomedical and visual science coursework (geometric and physiological optics, ocular pharmacology, neuro-optometry, systemic pathology) with two years of supervised direct patient care in on-campus eye clinics and external hospital/VA clinical rotations. An optional 1-year post-doctoral residency is available in ocular disease, cornea/contact lenses, pediatric optometry, or low-vision rehabilitation.

4. National Certification Exams & State Licensure

All 50 states require optometrists to hold an active state license issued by the State Board of Optometry. Licensure requires graduating from an ACOE-accredited O.D. program and passing all three parts of the National Board of Examiners in Optometry (NBEO) examination—Part I (Applied Basic Science), Part II (Patient Assessment and Management, including the Treatment and Management of Ocular Disease [TMOD] exam), and Part III (Patient Encounters and Performance Skills)—plus a state jurisprudence exam.

Optometrists may also earn voluntary board certification through the American Board of Optometry (ABO) or become a Fellow of the American Academy of Optometry (FAAO).

5. Salary Percentile Breakdown & Top-Paying Settings

Compensation for a Optometrist varies based on clinical experience, specialty certifications, shift differentials, geographic region, and facility type.
