You will take an eye test at your renewal appointment, and it usually takes less than five minutes

When you renew your driver's license, the DMV or your state's licensing office will test your vision before they issue your new license. This is not a full eye exam — it is a quick screening to make sure you can see well enough to drive safely. Most people pass without any trouble. If you do not pass, you will have options: you can get glasses or contacts and retake the test the same day, or you can explore for a restricted license that limits when and where you can drive.

The test itself is straightforward. You will look into a machine called a vision screener (sometimes called a visual acuity machine), read letters or symbols on a screen, and the machine records whether you meet your state's minimum vision standard. Some states still use a paper chart instead. Either way, the whole thing takes a few minutes and does not hurt.

Key Takeaways

  • The vision test at renewal checks whether you can see 20/40 or better in at least one eye; the exact standard varies by state.
  • You do not need a separate eye doctor's appointment — the DMV does the screening during your renewal visit.
  • If you wear glasses or contacts, bring them with you; the test measures your vision with correction if you normally use it.
  • Failing the test does not automatically mean you cannot renew; you can usually retake it after getting new glasses or contacts.
  • Some states offer restricted licenses for drivers whose vision does not meet the standard, limiting driving to daytime or familiar routes.

What the vision screener measures

The test measures your visual acuity — how clearly you can see letters or symbols at a standard distance. The machine shows you lines of letters that get smaller and smaller, and you read them aloud. The screener records the smallest line you can read accurately. Your state then compares that result to its minimum standard.

Most states require vision of 20/40 or better in at least one eye. That means you can see at 20 feet what a person with normal vision can see at 40 feet. Some states are stricter and require 20/30 or even 20/20. A few states allow 20/50 or 20/60 with a restricted license. Your state's DMV website will list the exact standard.

The test does not check for color blindness, depth perception, or side vision — only how clearly you can see straight ahead. If you have other vision problems, an eye doctor might catch them, but the DMV screener will not.

Bring your glasses or contacts if you use them

If you wear glasses or contact lenses while driving, wear them or bring them to your renewal appointment. The DMV tests your vision as you normally drive. If you usually wear glasses, the test measures your vision with them on. If you take the test without them and fail, that does not mean you have failed overall — it means you need to put on your glasses and retake it.

Your license may also be marked with a restriction code that says you must wear corrective lenses while driving. This is standard if you need glasses or contacts to meet the vision standard. It is not a problem; it just means you are legally required to wear them behind the wheel, which you should be doing anyway.

What happens if you do not pass

If you do not pass the vision test, you have several paths forward. The most common is to get new glasses or contacts and retake the test at the same appointment. Many DMV offices will retest you the same day at no extra charge. Bring your new prescription glasses or contacts with you, and you can usually pass on the second try.

If you do not have time to get new glasses that day, some states will issue you a temporary license valid for 30 to 60 days, giving you time to see an eye doctor and return for a retest. A few states will not renew your license at all until you pass, so check your state's policy before your appointment.

Some states also offer restricted licenses for drivers whose vision does not quite meet the standard. A restricted license might limit you to daytime driving only, or to driving within a certain distance of your home, or to roads you know well. The restrictions vary by state and by how much your vision falls short. If you are offered a restricted license, ask what the restrictions are before you decide whether to accept it.

How to prepare for your vision test

Get a good night's sleep before your appointment. Tired eyes do not focus as well, and you might fail a test you would otherwise pass. If you have been working at a computer all day, take a break and let your eyes rest before you go in.

If you wear glasses or contacts, clean them before you leave home. Smudges and dust can make it harder to read the letters on the screener. If your prescription is more than a year old and you have noticed your vision getting worse, consider seeing an eye doctor before your renewal appointment. That way you can get new glasses if you need them and avoid a failed test.

Bring your current license and any documents your state requires for renewal. The vision test is just one part of the renewal process, and you will need your paperwork in order to complete it.

Vision standards vary by state

Every state sets its own minimum vision standard for drivers. Most require 20/40 in at least one eye, but some are stricter. A few states allow 20/50 or 20/60 with restrictions. Some states also test both eyes separately; others only care about your better eye. A handful of states test for peripheral (side) vision or other measures beyond straightforward acuity.

Your state's DMV website will tell you the exact standard and what happens if you do not meet it. If you are renewing in a new state, check that state's standard — it may be different from your old state's, and you might need to retake the test even if you passed in your previous state.

When to see an eye doctor instead of just retaking the DMV test

If you fail the DMV vision test and you have not had an eye exam in more than a year, schedule an appointment with an eye doctor before you retake the DMV test. Your vision may have changed, and you might need a new prescription. An eye doctor can also check for conditions like cataracts, glaucoma, or macular degeneration that the DMV screener will not catch.

If you pass the DMV test but you have noticed that your vision is getting worse, or that you have trouble seeing at night, or that you are having trouble reading street signs while driving, see an eye doctor. The DMV test is a minimum safety check, not a full eye exam. Just because you pass does not mean your vision is as good as it could be.

Frequently Asked Questions

Can I use my phone's camera to read the letters on the vision screener?

No. The DMV will not allow you to use any device to help you read the test. If you try, you will fail the test and may be asked to leave. The screener is testing your actual vision, not your ability to use technology.

What if I have had eye surgery or a medical condition that affects my vision?

Tell the DMV staff before you take the test. If you have had LASIK, cataract surgery, or another procedure, your vision may be different than it was before. If you have a condition like diabetic retinopathy or a detached retina, the DMV needs to know. You may need a letter from your eye doctor confirming that you are safe to drive.

Do I have to pass the vision test to renew my license?

Yes, you must pass the vision test or meet the conditions of a restricted license to renew. If you do not pass and your state does not offer a restricted license, you will not be able to renew until your vision improves. Some states will issue a temporary license while you get new glasses.

How often do people fail the DMV vision test?

Most people pass on the first try. The exact number varies by state and age — older drivers fail more often than younger ones. If you wear glasses or contacts and bring them with you, your chances of passing are very high.

Can I get a medical exemption if I cannot pass the vision test?

Some states allow medical exemptions for drivers with certain conditions, but they are rare and require a letter from a specialist. You would need to contact your state's DMV directly to ask whether an exemption is possible in your situation.
