11 Apr, 2026
If you've ever wondered what does an optometrist do on a daily basis, you're not alone. It's one of the most commonly searched questions among aspiring healthcare professionals, and for good reason. Optometry sits at a fascinating crossroads of patient care, medical diagnostics, and specialized treatment — offering a career that's both intellectually stimulating and deeply rewarding. I've worked with thousands of healthcare professionals through healthcareers.app, and I can tell you that optometry consistently ranks among the most satisfying career paths in the healthcare industry.
In this comprehensive guide, I'll walk you through everything you need to know about what optometrists do, how to become one, what the job market looks like, and how this career compares to other healthcare paths — including the ever-popular nursing career and related roles. Whether you're a high school student exploring options, a career changer, or someone already working in healthcare looking to pivot, this guide is for you.
At its most fundamental level, an optometrist is a Doctor of Optometry (OD) who specializes in examining, diagnosing, and treating conditions related to the eyes and visual system. But that simple definition barely scratches the surface. Here's a detailed look at what optometrists actually do in practice:
The cornerstone of optometric practice is the comprehensive eye exam. During these appointments, optometrists evaluate patients' visual acuity, test for refractive errors like nearsightedness and farsightedness, and assess overall eye health. They use specialized instruments — including slit lamps, retinoscopes, and optical coherence tomography (OCT) machines — to examine the internal and external structures of the eye in extraordinary detail.
One of the most well-known aspects of what an optometrist does involves prescribing eyeglasses and contact lenses. After determining a patient's refractive error, optometrists write precise prescriptions that correct vision problems. This includes fitting specialty contact lenses for conditions like keratoconus or high astigmatism, which requires significant clinical expertise.
Optometrists are trained to diagnose and manage a wide range of ocular diseases, including:
While optometrists don't typically perform eye surgery (that's the domain of ophthalmologists), they play a critical role in co-managing surgical patients. They provide pre-operative evaluations for procedures like LASIK and cataract surgery, and they handle much of the post-operative follow-up care. This collaborative approach is a hallmark of modern eye care delivery.
Here's something many people don't realize: optometrists often detect systemic health problems during routine eye exams. Conditions like diabetes, hypertension, autoimmune disorders, and even certain cancers can present with early signs visible in the eye. According to the National Institutes of Health (NIH), the retina provides a unique non-invasive window into the body's vascular and neurological health, making eye exams valuable for overall health screening.
Becoming an optometrist requires a significant educational investment, but the payoff — both financially and in terms of career satisfaction — is substantial.
Most optometry programs require at least three years of undergraduate coursework, though the vast majority of admitted students hold a bachelor's degree. Pre-optometry coursework typically includes biology, chemistry, organic chemistry, physics, mathematics, and English. A strong GPA, especially in science courses, is essential for competitive applicants.
After completing prerequisite education, aspiring optometrists must earn a Doctor of Optometry degree from an accredited program. In the United States, there are currently 23 accredited schools and colleges of optometry. The OD program is a four-year graduate-level program that combines rigorous classroom instruction with extensive clinical rotations. Students study ocular anatomy, pharmacology, optics, visual science, and clinical diagnosis and management.
After earning their OD degree, graduates must pass the National Board of Examiners in Optometry (NBEO) examinations to obtain licensure in their state. All 50 states require optometrists to be licensed. Some optometrists also pursue residency training — typically one year — in specialties such as pediatric optometry, ocular disease, low vision rehabilitation, or contact lenses.
One of the most compelling reasons to consider optometry is the strong compensation and promising job market. According to the Bureau of Labor Statistics (BLS), the median annual wage for optometrists was approximately $125,590 as of their most recent data. The top 10 percent of earners in the field made more than $191,000 annually.
The BLS also projects employment of optometrists to grow by approximately 9 percent over the coming decade, which is faster than the average for all occupations. This growth is driven by an aging population that requires more eye care services, increased rates of diabetes and related eye conditions, and greater public awareness of the importance of regular eye exams.
Optometrists practice in a variety of settings, including:
At healthcareers.app, we help professionals explore the full spectrum of healthcare opportunities. If you're weighing optometry against other paths, here's how it stacks up against some common alternatives.
A nursing career is one of the most versatile and in-demand paths in all of healthcare. Registered nurses (RNs), nurse practitioners (NPs), and other nursing professionals work in virtually every healthcare setting imaginable. While a nursing career offers incredible flexibility, faster entry into the workforce, and a wide range of specializations, optometry provides a more focused scope of practice with the autonomy of running your own practice. Both are excellent choices — it really depends on your interests, temperament, and long-term goals.
If you're drawn to a nursing career, I encourage you to explore the many resources we offer on healthcareers.app. We regularly publish guides covering everything from RN licensure to advanced practice nursing specialties.
You might also encounter the LVN abbreviation as you research healthcare careers. LVN stands for Licensed Vocational Nurse, a title used in Texas and California (in most other states, the equivalent role carries the LPN abbreviation — Licensed Practical Nurse). Understanding the LVN abbreviation matters because it's one of the many entry points into healthcare that can eventually lead to advanced roles. An LVN provides basic nursing care under the supervision of registered nurses and physicians, and many LVNs use the role as a stepping stone toward becoming an RN or pursuing other healthcare careers.
Compared to an LVN role, optometry requires significantly more education and training, but it also offers higher compensation, greater autonomy, and a narrower clinical focus. There's no single "right" path — the best healthcare career is the one that aligns with your passions, lifestyle needs, and professional ambitions.
Beyond education and licensure, certain personal qualities and soft skills set exceptional optometrists apart from the rest:
The field of optometry is evolving in exciting ways. Advances in telemedicine are expanding access to eye care in rural and underserved communities. Artificial intelligence tools are being developed to assist with screening for conditions like diabetic retinopathy and glaucoma. Many states are also expanding the scope of practice for optometrists, granting them privileges to perform certain laser procedures and minor surgeries that were previously reserved for ophthalmologists.
According to the American Optometric Association, the integration of optometrists into primary care teams is also growing, reflecting the broader shift toward value-based, patient-centered care in the United States. For aspiring optometrists, these trends signal a future full of opportunity and professional growth.
An optometrist (OD) provides primary eye care, including eye exams, vision correction prescriptions, and diagnosis and management of many eye diseases. An ophthalmologist (MD or DO) is a medical doctor who specializes in eye and vision care, including performing eye surgery. Both professionals are essential to the eye care team, and they often collaborate to provide comprehensive patient care.
Yes. All 50 states permit optometrists to prescribe medications for eye conditions, including antibiotics, anti-inflammatories, and glaucoma medications. The specific scope of prescribing authority varies by state, but the trend has been toward expanding optometric prescribing privileges over the past several decades.
The typical path to becoming an optometrist takes about eight years after high school: four years of undergraduate education followed by four years in a Doctor of Optometry program. Some students complete an optional one-year residency after graduation for additional specialized training.
Absolutely. One of the aspects I hear optometrists praise most often is the work-life balance the profession offers. Most optometrists work standard business hours, rarely face overnight or weekend shifts (unlike many in a nursing career or emergency medicine), and enjoy a predictable schedule. Private practice owners have even greater control over their work hours, which is a major draw for many professionals.
When browsing optometry positions on platforms like healthcareers.app, pay attention to the practice setting, patient volume expectations, compensation structure (salary vs. production-based), benefits packages, and opportunities for professional development. If you're interested in ownership, look for associateship positions that offer a buy-in pathway.
Understanding what an optometrist does is the first step toward deciding if this career path is right for you. Optometry offers a unique combination of patient interaction, clinical expertise, diagnostic challenge, and business opportunity that few other healthcare professions can match. With strong compensation, excellent job growth projections from the Bureau of Labor Statistics, and an evolving scope of practice, the future of optometry has never looked brighter.
