The timeline is four years of optometry school after your bachelor's degree
To become a licensed optometrist in the United States, you need a four-year Doctor of Optometry degree (O.D.) from an accredited optometry school. This comes after you finish a bachelor's degree, which typically takes four years. So the minimum time from high school to optometrist is eight years of full-time study, though the actual path varies based on when you take the licensing exam and whether you pursue additional training.
The four years of optometry school are not negotiable—every accredited program in the U.S. requires this length. However, the years before optometry school can shift. Some students complete their bachelor's degree in three years through accelerated programs or by entering with college credits. Others take longer if they need to retake courses or change majors. The total time also depends on whether you pursue a residency after optometry school, which adds one to three years but is optional for most positions.
Key Takeaways
- A four-year Doctor of Optometry degree is required after completing a bachelor's degree, making the minimum timeline eight years from high school.
- Optometry school admission requires specific prerequisite courses in biology, chemistry, organic chemistry, and physics, which you complete during your bachelor's degree.
- You must pass the Optometry Admission Test (OAT) before explore to optometry school, and this test preparation typically takes three to six months.
- After graduation, you must pass the National Board of Examiners in Optometry (NBEO) licensing exams and your state's practical exam before you can practice independently.
- A residency program after optometry school is optional and takes one to three years, but it is required if you want to specialize in areas like pediatric optometry or low-vision care.
What you need to complete before optometry school
Before you can explore to optometry school, you must finish a bachelor's degree in any major. However, optometry schools require specific prerequisite courses that you typically take during your undergraduate years. These include one year of biology with lab, one year of general chemistry with lab, one year of organic chemistry with lab, one year of physics with lab, and one year of biochemistry. Some schools also require courses in microbiology, anatomy, or statistics. Check the prerequisites for the specific schools you are interested in, because they vary slightly.
You also need to take the Optometry Admission Test (OAT), a standardized exam that tests your knowledge of natural sciences, reading comprehension, and physics. Most students prepare for the OAT for three to six months while finishing their bachelor's degree or shortly after. You can take the test multiple times if needed, though schools see all your scores. Admission committees look at your overall GPA, your science course GPA, your OAT score, and your work or volunteer experience in eye care settings.
The four years of optometry school
Optometry school is structured similarly across all accredited programs in the U.S. The first two years focus on classroom and laboratory work covering anatomy of the eye, physiology, optics, pharmacology, and disease diagnosis. You learn how the eye works, how to prescribe lenses, and how to recognize eye diseases. The second two years shift toward clinical practice, where you work with real patients under supervision in the school's clinic or affiliated practices. By your final year, you are seeing patients with minimal oversight.
All four years are full-time commitments. Most optometry schools run on a traditional academic calendar with fall and spring semesters, though some use a trimester system that moves faster. You cannot compress the four years into three, and you cannot attend part-time. The curriculum is set by accreditation standards, so every school covers the same core material, though they may emphasize different specialties or practice settings.
Licensing exams after graduation
After you graduate with your O.D., you must pass licensing exams before you can practice. The National Board of Examiners in Optometry (NBEO) administers three written exams: the National Board Exam Part I (covering basic science), Part II (covering clinical optometry), and Part III (covering advanced clinical topics and ethics). Most graduates take Part I and Part II before graduation or when ready after, and Part III within the first year of practice. You must pass all three exams to be licensed.
In addition to the NBEO exams, every state requires you to pass a practical exam that tests your ability to perform eye exams and fit contact lenses. Some states use the NBEO's Practical Exam, while others have their own. You typically take the practical exam in your final year of optometry school or within a few months after graduation. Once you pass all required exams and submit your process to your state's optometry board, you receive your license to practice independently.
Residency programs add one to three years
After earning your O.D. and passing licensing exams, you can work as an optometrist when ready. However, some optometrists pursue a residency program, which is a one- to three-year specialized training program in areas like pediatric optometry, sports vision, low-vision rehabilitation, ocular disease, or corneal and contact lens specialty. Residencies are not required to practice as an optometrist, but they are necessary if you want to specialize or work in certain settings like hospitals or research institutions.
Residency programs are competitive and typically require strong academic performance during optometry school and relevant clinical experience. They are paid positions, though the salary is usually lower than what you would earn as a practicing optometrist. If you pursue a residency, add one to three years to your total timeline depending on the program length and your specialty.
Timeline variations based on your path
The eight-year minimum assumes you complete your bachelor's degree in four years and move directly into optometry school. However, real timelines vary. If you need to retake prerequisite courses or change majors during your bachelor's degree, you may spend five or six years on your undergraduate work. If you work for a year or two before explore to optometry school to gain eye care experience or save money, that extends the timeline further.
Some students also take a gap year between their bachelor's degree and optometry school to work as an optometric technician, which strengthens their process and gives them real-world experience. This is common and does not delay your career—it straightforward shifts when you start optometry school. If you know you want to specialize, factor in an additional one to three years for a residency after graduation.
Part-time study and online options
Optometry school itself cannot be completed part-time or online. The four-year Doctor of Optometry degree requires full-time attendance and hands-on clinical training that cannot be done remotely. However, your bachelor's degree can sometimes be completed faster through online courses, community college credits, or accelerated programs, which can shorten the years before optometry school.
Some optometry schools offer evening or weekend clinical hours to accommodate students who work, but the overall program length remains four years. If you are considering optometry as a career while working full-time, plan to leave your job or reduce your hours once you start optometry school, as the coursework and clinical requirements do not allow for substantial outside employment.
Frequently Asked Questions
Can I become an optometrist in less than eight years?
No. The four-year optometry degree is fixed, and you need a bachelor's degree first, which is typically four years. You might shorten your bachelor's degree to three years through accelerated programs or prior credits, bringing the total to seven years, but this is rare and depends on your school's policies.
Do I have to do a residency after optometry school?
No. A residency is optional. You can practice as a general optometrist when ready after passing your licensing exams. Residencies are only necessary if you want to specialize in a specific area like pediatric care or low-vision rehabilitation, or if you want to work in certain settings like hospitals or research.
What if I don't pass the licensing exam on my first try?
You can retake the exam. There is no limit on how many times you can attempt the NBEO exams or your state's practical exam, though you must pay the exam fee each time. Most students pass on their first attempt, but retaking adds a few months to your timeline.
Can I work as an optometrist while studying for my licensing exams?
No. You must be licensed before you can practice independently. Some graduates work as optometric technicians or in other eye care roles while preparing for exams, but you cannot perform optometric services like eye exams or writing prescriptions without a license.
How long does it take to get licensed after I graduate?
The licensing process typically takes two to four months after you submit your process to your state board, assuming you have already passed all required exams. The timeline depends on your state's processing speed and whether you need to schedule your practical exam.
