Missouri requires a vision screening at renewal, but you can often pass it without an eye exam
When you renew your Missouri driver's license, the Department of Revenue will test your vision as part of the renewal process. This is not an optional step — it happens at every renewal, whether you renew in person at a license office or by mail. The vision test itself is straightforward: you read letters or numbers on a chart from a set distance, usually about 20 feet away. If you pass, your renewal moves forward. If you do not pass, Missouri will restrict your license or ask you to get an eye exam from an optometrist or ophthalmologist before they issue your new license.
The key detail most people miss is that you do not need a separate eye doctor visit before you renew. You take the vision test as part of the renewal process itself. If you fail that test, then you need the eye exam. This matters because it saves time and money for people whose vision has not changed.
Key Takeaways
- Missouri tests your vision during the renewal appointment or mail-in process, and you must pass to get an unrestricted license.
- If you fail the vision test at the license office, you will be asked to get an eye exam from an optometrist or ophthalmologist and bring the results back.
- Passing the test means your vision is at least 20/40 in each eye, with or without corrective lenses like glasses or contacts.
- If you wear glasses or contacts, bring them to your renewal appointment — the test accounts for correction.
- Some people renew by mail, but they still must pass a vision test; if they do not, they will be notified and asked to visit a license office in person.
How the vision test works at the Missouri license office
When you arrive for your renewal appointment, a staff member at the Department of Revenue office will administer the vision screening. You will stand or sit at a marked distance from a chart and read letters or numbers aloud. The test checks each eye separately and then both eyes together. If you wear glasses or contacts, you wear them during the test — Missouri is checking whether your corrected vision meets the standard, not your uncorrected vision.
The passing standard in Missouri is 20/40 vision in each eye. That means you can read at 20 feet what a person with standard vision can read at 40 feet. This is lower than the 20/20 standard most people think of, so many people who believe their vision is poor still pass. The test also checks your peripheral vision — your ability to see to the sides without moving your eyes — because that matters for safe driving.
If you pass, the test takes less than a minute and you move on to the rest of your renewal. If you do not pass, the staff member will explain what happened and tell you that you need an eye exam before Missouri can issue your renewed license.
What happens if you fail the vision test
Failing the vision test does not mean your renewal is denied. It means you must get an eye exam from a licensed optometrist or ophthalmologist and bring the results to the license office. The eye doctor will test your vision and, if you need glasses or contacts, will write a prescription. You then take that exam result — usually a form the eye doctor fills out — back to the Department of Revenue.
The eye doctor's report must show that your vision can be corrected to at least 20/40 in each eye. If it can be, Missouri will issue your license, often with a restriction that you must wear your glasses or contacts while driving. If your vision cannot be corrected to that standard even with lenses, Missouri may issue a restricted license that limits when or where you can drive, or they may deny renewal until your vision improves.
Getting the eye exam usually takes a few days to a week to schedule, depending on your eye doctor's availability. The exam itself costs money — typically between $75 and $150 — and is not covered by the renewal fee. Once you have the results, you can return to the license office to complete your renewal.
Renewing by mail and the vision test
Missouri allows some people to renew their driver's license by mail instead of visiting a license office in person. However, mail renewal does not skip the vision test. Instead, you complete a self-administered vision screening form that comes with your renewal packet. You read a chart at home from a specific distance and mark whether you can see the letters or numbers clearly.
If you pass the mail-in vision screening, your renewal continues by mail and you receive your new license in the mail. If you fail or do not complete the screening, Missouri will notify you and ask you to visit a license office in person to take the vision test there. At that point, the process is the same as if you had come in person from the start.
The mail-in vision screening is less precise than the in-person test because it relies on you to measure distance and read accurately at home. Some people who would pass the in-person test fail the mail-in version, and vice versa. If you are unsure about your vision or have had changes in your eyesight, visiting in person is more reliable.
Preparing for your vision test at renewal
If you wear glasses or contacts, bring them with you to your renewal appointment. Wear them on the day of your visit if possible, so your eyes are adjusted. If you have recently changed your glasses prescription, bring your current pair. Do not wear sunglasses into the license office, and let the staff member know if you have any eye conditions or if your vision has changed since your last renewal.
If you have not had an eye exam in several years and you are concerned about your vision, you can get an eye exam before your renewal appointment. This is optional — you only need it if you fail the test at the license office — but it can save you a trip if you know your vision has declined. An eye exam costs money, so weigh whether you think you will fail the test before paying for one in advance.
On the day of your appointment, arrive a few minutes early and bring your current driver's license and any other documents the Department of Revenue requires for renewal. The vision test is quick, but having everything ready keeps the whole process moving.
Vision restrictions on your renewed license
If you pass the vision test or if you pass an eye exam after failing the test, Missouri may add a restriction to your license. The most common restriction is "corrective lenses required" — meaning you must wear your glasses or contacts while driving. This restriction appears on your license and is legally binding. Driving without your corrective lenses when this restriction is in place is a violation.
Other restrictions are less common but possible. If your peripheral vision is limited or if you have other eye conditions that affect driving safety, Missouri may restrict your license to daytime driving only, or to driving within a certain distance of your home. These restrictions are based on the eye doctor's report and the Department of Revenue's assessment of driving safety.
Restrictions do not prevent you from renewing. They straightforward set conditions on how you can legally drive. If your vision improves or if you get new glasses that correct your vision better, you can request that a restriction be removed at your next renewal.
Frequently Asked Questions
Can I wear contacts instead of glasses for the vision test?
Yes. Missouri tests your vision with whatever corrective lenses you normally wear — glasses, contacts, or both. If you wear contacts, wear them to your appointment. If you wear glasses, bring them. The test measures whether your corrected vision meets the standard, not which type of correction you use.
What if I fail the vision test but I do not think I should have?
You can request that the test be administered again, usually by a different staff member. If you fail a second time, you will need an eye exam from an optometrist or ophthalmologist. That exam is the definitive measure of your vision and whether you can drive safely.
How long does the vision test take?
The vision screening itself takes less than a minute if you pass. If you fail, the staff member will explain the result and tell you what to do next, which adds a few more minutes to your appointment. The entire renewal appointment, including vision test, usually takes 15 to 30 minutes.
Do I have to pay extra for the vision test?
No. The vision test is included in your renewal fee. You only pay extra if you fail the test and need to get an eye exam from an eye doctor, which is a separate cost not covered by the Department of Revenue.
What if I have a medical condition that affects my vision?
Tell the staff member at the license office about any eye conditions you have, such as cataracts, glaucoma, or macular degeneration. They will note this and may ask you to bring documentation from your eye doctor. The vision test still applies, but the staff member will have context for your results.
