Optometrists are primary eye care providers who examine eyes for vision and health problems, diagnose conditions such as nearsightedness, farsightedness, astigmatism, glaucoma, cataracts, macular degeneration, and diabetic retinopathy, prescribe corrective lenses (glasses and contact lenses), prescribe medications for eye conditions, provide pre- and post-operative care for eye surgeries, and manage chronic eye diseases. Optometrists hold the Doctor of Optometry (OD) degree and are distinct from ophthalmologists (MDs or DOs who perform eye surgery) and opticians (technicians who fit and dispense eyeglasses). The optometry profession combines clinical expertise with the opportunity for practice ownership and a generally favorable work-life balance.
Education Pathway
Undergraduate (3 to 4 years): Most optometry schools require at least 3 years of undergraduate coursework with prerequisites (biology, general chemistry, organic chemistry, physics, mathematics, statistics, English, and psychology). Some students complete a full bachelor’s degree; others enter optometry school after 3 years of undergraduate work if they have completed all prerequisites. OAT®: The Optometry Admission Test assesses academic ability in natural sciences, reading comprehension, quantitative reasoning, and physics. See our OAT® prep guide. Optometry School (4 years): The OD curriculum includes ocular anatomy, ocular physiology, optics, pharmacology, pathology, clinical diagnosis, contact lens fitting, low vision rehabilitation, pediatric optometry, binocular vision, and extensive clinical rotations. Apply through OptomCAS (Optometry Centralized Application Service). See our OptomCAS guide. Optional Residency (1 year): Residencies in areas like pediatric optometry, geriatric optometry, ocular disease, low vision rehabilitation, and primary care optometry provide advanced training but are not required for practice.
What Optometrists Do
A typical day for an optometrist in private practice includes performing comprehensive eye exams (testing visual acuity, checking for refractive errors, evaluating eye alignment and coordination, examining the internal and external structures of the eye using specialized instruments), prescribing glasses and contact lenses, diagnosing and managing eye diseases (glaucoma, macular degeneration, diabetic retinopathy, dry eye, infections), prescribing ophthalmic medications (eye drops for infections, inflammation, glaucoma, and allergies), managing chronic conditions that affect the eyes (diabetes, hypertension, autoimmune diseases), providing vision therapy for patients with binocular vision disorders, and counseling patients on eye health and prevention strategies (UV protection, screen time management, nutrition for eye health).
Optometrists who own their practices also manage business operations: hiring and supervising staff, selecting and maintaining equipment, managing billing and insurance, marketing the practice, and selecting eyeglass and contact lens inventory. Practice ownership gives optometrists significant professional autonomy and business income beyond their clinical compensation. Some optometrists work in group practices, hospital systems, VA medical centers, community health centers, or corporate settings (retail optical chains), where they focus exclusively on clinical care without the business management responsibilities.
The scope of optometric practice has expanded significantly in recent years. Many states now allow optometrists to perform minor surgical procedures (foreign body removal, certain eyelid procedures) and to use advanced diagnostic techniques (optical coherence tomography, fundus photography) that were previously limited to ophthalmologists. This expanded scope increases the clinical complexity and professional satisfaction of optometric practice.
Salary and Job Outlook
The median annual salary for optometrists is approximately $130,860 according to the Bureau of Labor Statistics. Salaries range from approximately $80,000 for entry-level associates to $200,000+ for experienced practitioners who own successful practices. Optometry school tuition averages $150,000 to $250,000 for the four-year program. The profession is projected to grow 9 percent through 2032, driven by aging population vision needs, increasing screen time contributing to myopia and digital eye strain, expanding scope of practice, and growing demand for diabetic eye care as diabetes prevalence increases. Practice ownership provides additional income potential but requires capital investment ($200,000 to $500,000+ to purchase or start a practice).
Advantages and Challenges
Advantages: Excellent work-life balance (most optometrists work regular business hours with no call), strong salary with practice ownership potential, high patient satisfaction (helping people see clearly produces immediate and tangible results), expanding scope of practice, low emergency burden compared to physicians, and the intellectual satisfaction of combining clinical medicine with optics and technology.
Challenges: Significant educational debt, competition from corporate optical chains that may reduce the autonomy and profitability of independent practice, the limited scope of practice compared to ophthalmologists (optometrists cannot perform most eye surgeries), and the repetitive nature of routine eye exams (which constitute the majority of patient visits for many optometrists).
Getting Started
Middle school: Explore science and learn about the eye. High school: Take AP® sciences, volunteer in healthcare, and shadow an optometrist. Undergraduate: Complete prerequisites, build clinical experience (optometry office volunteering or employment), prepare for the OAT®, and apply through OptomCAS.
Myopia Management: The prevalence of myopia (nearsightedness) is increasing worldwide, driven in part by increased screen time and decreased outdoor activity. Optometrists are at the forefront of myopia management, a growing subspecialty focused on slowing the progression of myopia in children through interventions such as specialized contact lenses (orthokeratology, multifocal soft lenses), low-dose atropine eye drops, and lifestyle counseling (increased outdoor time). Myopia management is a rapidly evolving field that combines clinical care with emerging research, and it represents a growing revenue stream for optometric practices serving pediatric populations.
Optometry and Technology: Modern optometric practice relies heavily on advanced diagnostic technology. Optical coherence tomography (OCT) provides cross-sectional images of the retina that enable early detection of glaucoma, macular degeneration, and diabetic retinopathy. Corneal topography maps the surface of the cornea for contact lens fitting and refractive surgery planning. Fundus photography creates high-resolution images of the retina for monitoring and documentation. Visual field testing detects and monitors peripheral vision loss from glaucoma and neurological conditions. Optometrists who enjoy working with technology and interpreting complex diagnostic data find this aspect of the profession intellectually stimulating. The integration of artificial intelligence into ophthalmic imaging is an emerging development that may further transform how optometrists diagnose and manage eye diseases. See our AI in medicine page.
OD vs. Ophthalmologist: Students interested in eye care often debate between optometry (OD, 4 years after prerequisites) and ophthalmology (MD or DO plus 4-year ophthalmology residency, totaling 12+ years). Optometrists provide primary eye care, prescribe glasses and contacts, diagnose and manage most eye diseases, and perform minor procedures in some states. Ophthalmologists are eye surgeons who perform cataract surgery, LASIK, retinal surgery, glaucoma surgery, and other complex procedures. The decision depends on whether you want a shorter training pathway with broader primary care scope (optometry) or a longer surgical training pathway with the ability to perform complex procedures (ophthalmology). Both professions are essential to the eye care system, and they frequently collaborate in patient care.
Contact Lens Practice: Contact lens fitting and management is a significant component of optometric practice and a service that ophthalmologists generally do not provide. Optometrists fit standard soft lenses, toric lenses for astigmatism, multifocal lenses for presbyopia, rigid gas permeable lenses, scleral lenses for irregular corneas (keratoconus, post-surgical corneas), and specialty lenses for therapeutic purposes. Contact lens technology is advancing rapidly, with new materials, designs, and applications (myopia control lenses, drug-eluting lenses, smart lenses with sensors) creating both clinical and commercial opportunities. Optometrists who develop expertise in specialty contact lens fitting serve a patient population that cannot be adequately helped by standard eyeglasses alone, providing a highly specialized and personally rewarding clinical service. Contact lens revenues also contribute significantly to the financial health of optometric practices, as both the professional fitting fees and the ongoing supply purchases generate recurring income.
