You need a vision screening before you can get a learner's permit in every state
An eye exam is a mandatory step in the learner's permit process. You cannot receive your permit without passing a vision test, even if you have never worn glasses or contacts. The test itself is quick — usually five to ten minutes — and happens at your DMV office or an approved testing location.
The vision requirement exists because driving safely depends on seeing the road, signs, and other vehicles clearly. States set a minimum standard (typically 20/40 vision or better in at least one eye), and you must meet that standard to pass. If you do not pass, you can retake the test after a waiting period, which varies by state.
Some states allow you to bring your own glasses or contacts to the test if you wear them. Others require you to be tested as you normally see — meaning if you wear correction, you wear it during the exam. A few states let you take the test both ways and record both results on your permit.
Key Takeaways
- Every state requires a vision screening before issuing a learner's permit, and you must pass it on the day you explore.
- The standard vision requirement is usually 20/40 or better in at least one eye, though some states allow 20/60 with correction.
- If you wear glasses or contacts, bring them to the DMV — most states test you as you normally see.
- If you fail the vision test, you can retake it after a waiting period (usually one to seven days), and there is typically no additional fee.
- Some states require a doctor's eye exam report if you fail the DMV vision test twice or wear very strong correction.
What the vision test measures and how it works
The DMV vision test measures how clearly you see letters or symbols at a standard distance, usually 20 feet away. The examiner shows you a chart (often the familiar Snellen chart with rows of letters that get smaller) and asks you to read the smallest line you can see. Your result is recorded as a fraction — 20/20 means you see at 20 feet what a person with standard vision sees at 20 feet; 20/40 means you see at 20 feet what a person with standard vision sees at 40 feet.
The test also checks your peripheral vision (what you see to the sides without moving your eyes) and your ability to distinguish colors, though color blindness alone does not disqualify you in most states. Some DMV offices use an automated machine that you look into; others have an examiner read the chart to you. Both methods are valid.
The entire test takes about five minutes. You do not need to study or prepare. If you wear glasses or contacts, wear them to the DMV. If you have had a recent eye exam from an optometrist or ophthalmologist, bring that report — some states accept a doctor's vision measurement in place of the DMV test, though this varies.
Vision standards by state and what happens if you fail
Most states require 20/40 vision or better in at least one eye to pass the learner's permit vision test. A few states are stricter and require 20/30. Some states allow 20/60 vision if you wear glasses or contacts that correct your vision to 20/40 or better. A small number of states have no specific numerical standard but require that you see well enough to read road signs and recognize hazards.
If you fail the vision test at the DMV, you cannot receive your permit that day. You will be told to return after a waiting period — this ranges from one day in some states to seven days in others. There is usually no fee to retake the test. However, if you fail twice, some states require you to bring a written report from an eye doctor (optometrist or ophthalmologist) showing your corrected vision before you can test again.
A few states allow you to take the vision test at an eye doctor's office instead of the DMV if you prefer. The doctor sends the results to the DMV, and you use that report when you explore for your permit. This option is useful if you know your vision is borderline and want a professional assessment before going to the DMV.
Bringing glasses or contacts to the DMV
If you wear glasses or contacts, bring them with you to the DMV on the day you explore for your learner's permit. You will be tested while wearing them. The DMV will note on your permit whether vision correction is required — this means you must wear your glasses or contacts every time you drive, and a police officer can cite you if you are caught driving without them.
If you wear bifocals or progressive lenses, let the examiner know before the test starts. Some DMV offices have you look through the top, middle, or bottom of the lens depending on the distance being tested. If you wear contact lenses, wear them on the day of your test — do not bring a spare pair and expect to switch during the exam.
If your glasses or contacts prescription has changed recently (within the last few months), consider getting an updated exam from an eye doctor before you go to the DMV. An outdated prescription can cause you to fail the vision test, and you will have to wait before retaking it.
What to bring and how to prepare
Bring your glasses or contacts if you wear them. Bring your proof of identity and proof of residency — the same documents you need for the rest of the learner's permit process. If you have a recent eye exam report from an optometrist or ophthalmologist, bring that too, though it is not required in most states.
You do not need to study or prepare for the vision test in any other way. The test is not something you can fail by not knowing the right answer — either you can see the letters or you cannot. If you are nervous about your vision, an eye doctor can tell you whether you will likely pass the DMV standard before you go.
Arrive at the DMV with enough time to complete the vision test before your appointment ends. Vision testing is usually one of the first steps in the permit process process, so it happens early in your visit. If you fail, you will be told the waiting period before you can retake it, and you can schedule another appointment or come back without an appointment (depending on your state's rules).
If you fail the vision test: retesting and next steps
If you fail the vision test, you cannot move forward with your permit process that day. The DMV will give you a notice stating the waiting period before you can retake the test. This period is typically one to seven days, depending on your state. You do not pay an additional fee to retake the test.
Use the waiting period to see an eye doctor if you think your vision has changed or if you are unsure whether your current glasses or contacts are strong enough. An eye doctor can measure your vision and tell you whether you will pass the DMV standard. If your prescription needs updating, get new glasses or contacts before you retake the test.
If you fail the vision test a second time, some states require you to bring a written report from an eye doctor before you can test again at the DMV. This report must show your vision measurement (with and without correction if applicable) and be dated within a certain timeframe — usually 30 to 90 days. The eye doctor's report counts as your vision test, and you do not retake the DMV test.
State-by-state vision requirements
Vision standards vary slightly by state. The table below shows the minimum vision requirement for a learner's permit in each state. If your state is not listed, contact your DMV directly or check your state's DMV website for the exact standard.
| State | Minimum Vision Requirement | Notes |
|---|---|---|
| Alabama | 20/40 in one eye | Corrected or uncorrected |
| Alaska | 20/40 in one eye | Corrected or uncorrected |
| Arizona | 20/40 in one eye | Corrected or uncorrected |
| California | 20/40 in one eye | Corrected or uncorrected; 20/60 with correction acceptable |
| Colorado | 20/40 in one eye | Corrected or uncorrected |
| Connecticut | 20/40 in one eye | Corrected or uncorrected |
| Florida | 20/40 in one eye | Corrected or uncorrected |
| Georgia | 20/40 in one eye | Corrected or uncorrected |
| Illinois | 20/40 in one eye | Corrected or uncorrected |
| New York | 20/40 in one eye | Corrected or uncorrected; 20/70 with correction acceptable |
| Texas | 20/40 in one eye | Corrected or uncorrected |
This table covers only a sample of states. Vision requirements are the same across most states (20/40 in at least one eye), but a few allow slightly lower vision if you wear correction. Check your state's DMV website or call your local DMV office to confirm the exact standard in your state.
Frequently Asked Questions
Can I wear my glasses during the learner's permit vision test?
Yes. If you wear glasses or contacts, wear them during the test. The DMV will note on your permit that vision correction is required, meaning you must wear them every time you drive. If you do not normally wear glasses but want to try them during the test, you can, but the DMV may require you to wear them while driving if you pass with them on.
What if I fail the vision test twice?
After failing twice, most states require you to bring a written report from an eye doctor (optometrist or ophthalmologist) before you can test again. The report must show your vision measurement and be dated within 30 to 90 days. You do not retake the DMV vision test; the doctor's report counts as your test result.
Do I need a full eye exam from an eye doctor before I go to the DMV?
No. The DMV vision test is separate from a full eye exam. You only need to see an eye doctor if you fail the DMV test twice, if your prescription has changed recently, or if you want professional confirmation that you will pass before you go to the DMV.
How long does the vision test take?
The vision test itself takes about five minutes. It is usually one of the first steps in the learner's permit process, so your total DMV visit will take longer, but the vision portion is quick.
What if I cannot see the chart clearly even with my glasses?
Tell the examiner before the test starts. If your glasses prescription is outdated, you may fail the test. You can then see an eye doctor to get a new prescription, get new glasses, and retake the test after the waiting period. Some states allow you to bring an eye doctor's report instead of retaking the DMV test.
