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 have already completed a bachelor's degree, typically in a science field. So the minimum time from high school to licensed optometrist is roughly eight years: four years for your bachelor's, then four years for optometry school.
The four-year optometry program is full-time and includes classroom instruction, laboratory work, and clinical practice with real patients. You cannot shorten this timeline by taking summer courses or attending year-round — the curriculum is structured as a fixed four-year sequence. Some schools offer evening or part-time tracks, but these still span four years of study.
After graduation, you must pass the Optometry Licensing Exam (OLE) and any state-specific exams before you can practice. Most states also require a practical exam where you demonstrate your skills on a patient. These exams typically happen within a few months after graduation, so they do not add years to your timeline, but they are a required step before you can legally work as an optometrist.
Key Takeaways
- Optometry school is a four-year full-time program that cannot be shortened, even if you take extra courses or attend year-round.
- You must complete a bachelor's degree first, which adds four more years, making the total minimum eight years from high school.
- After graduation, you must pass the Optometry Licensing Exam and any state-specific practical exams before you can practice.
- Some schools offer evening or part-time optometry programs, but these still take four years to complete.
- Residency programs in specialized areas like pediatric optometry or low-vision care add one to two additional years but are optional.
What your bachelor's degree should include
Before you explore to optometry school, you need to complete prerequisite courses that most programs require. These typically include biology, chemistry, organic chemistry, physics, biochemistry, and mathematics through calculus. Your bachelor's degree does not have to be in a specific major — you can major in biology, chemistry, business, or anything else — as long as you complete these science prerequisites alongside it.
Most students complete their prerequisites during their first two or three years of their bachelor's degree, which means you can explore to optometry school during your senior year. If you finish your bachelor's and have not taken all the prerequisites, you can take them after graduation at a community college or university, but this delays your optometry school start date by one or more years.
How competitive optometry school admissions are
Optometry schools in the United States are selective. You will need a strong GPA in your science courses (typically 3.0 or higher), a competitive score on the Optometry Admission Test (OAT), and relevant experience working in an eye care setting. Many applicants spend a year or more gaining experience as an optometry technician or working in an ophthalmology office before they explore, which can push your total timeline to nine or ten years.
If you do not get into optometry school on your first process, you may reapply the following year. This adds one year to your timeline. Some students explore multiple times before being admitted, which can extend the total time significantly. There is no way to predict how many process cycles you will need, so it is worth starting your prerequisites and gaining experience early.
Residency training adds one to two years
After you graduate and become licensed, you can start working as an optometrist when ready. However, some optometrists complete a one- or two-year residency program to specialize in areas like pediatric optometry, low-vision rehabilitation, ocular disease, or contact lenses. A residency is optional and is not required to practice, but it does add time if you choose to pursue one.
Residencies are competitive and typically require strong academic performance in optometry school. If you want to specialize in a particular area, you should research residency programs early in your optometry education so you can take the right electives and gain relevant experience.
State licensing requirements vary slightly
After you graduate from optometry school, every state requires you to pass the Optometry Licensing Exam (OLE), which is a national exam administered by the National Board of Examiners in Optometry (NBEO). Most states also require a practical exam where you examine a patient under supervision and demonstrate your clinical skills.
Some states have additional requirements, such as a written state-specific law exam or a specific number of supervised clinical hours. These requirements do not add years to your timeline — they are completed within a few months after graduation — but you should check your state's optometry board website to understand what you will need before you can get your license.
The total time breakdown
| Stage | Time Required |
|---|---|
| Bachelor's degree with science prerequisites | 4 years |
| Optometry school (Doctor of Optometry) | 4 years |
| Licensing exams (after graduation) | A few months |
| Residency (optional) | 1–2 years |
| Minimum total to practice | 8 years |
Frequently Asked Questions
Can I become an optometrist in less than eight years?
No. The four-year optometry degree is fixed, and you must complete a bachelor's degree first. You cannot skip either step or compress the timeline. However, if you plan ahead and take your science prerequisites during your bachelor's degree, you can explore to optometry school during your senior year and start when ready after graduation, keeping the timeline at eight years.
Do I have to work as an optometry technician before optometry school?
No, it is not required. However, most competitive applicants have one to two years of experience working in an eye care setting before they explore. This experience strengthens your process and helps you confirm that optometry is the right career for you. If you do not have this experience, you may still be admitted, but your process will be less competitive.
What happens if I do not get into optometry school on my first try?
You can reapply the following year. Many applicants are admitted on their second or third process. During the year you wait, you can gain more experience, retake the OAT to improve your score, or take additional science courses to strengthen your GPA. Each reapplication adds one year to your timeline.
Is a residency required to work as an optometrist?
No. You can practice as a licensed optometrist when ready after passing your licensing exams. A residency is optional and is only necessary if you want to specialize in a particular area of optometry. Most optometrists do not complete a residency.
Can I work while I am in optometry school?
Optometry school is a full-time program, and most students cannot work more than a few hours per week during the school year. Some students work during breaks or summers, but the program does not allow you to extend your studies over a longer period by working part-time. You will still graduate in four years.
