You will need a current vision test to renew your driver's license, and most states require it to happen within a certain window before or after your renewal date

The vision test is a standard part of license renewal in all 50 states. The test itself is straightforward — you read letters or numbers on a chart from a set distance, usually 20 feet away. The examiner checks each eye separately and together, and notes whether you meet your state's minimum vision standard, which is typically 20/40 or better in at least one eye.

Where and when you take the test depends on your state's rules. Some states let you take it at the DMV during your renewal appointment. Others require you to visit an eye care professional — an optometrist or ophthalmologist — beforehand and bring the results with you. A few states allow you to take a vision test online through an approved vendor, though this is less common and has specific requirements.

The test costs nothing if you do it at the DMV as part of your renewal. If your state requires a separate eye exam, you will pay the eye care provider's fee, which varies widely depending on whether they do a full exam or just the vision screening. Many vision insurance plans cover routine eye exams, so check your coverage before you schedule.

Key Takeaways

  • Your state's DMV website will tell you whether you can take the vision test at your renewal appointment or must visit an eye care provider first.
  • The test checks whether you meet your state's minimum vision standard, usually 20/40 or better in at least one eye.
  • If you fail the vision test, you can retake it after getting glasses or contacts, but you cannot renew your license until you pass.
  • Some states accept vision test results from an eye care provider for a set period — typically 12 months — so you may not need a new test if you had one recently.
  • Bring your current glasses or contacts to the test if you wear them, because the test measures your vision with correction.

Where to take your vision test

Check your state's DMV website to find out whether your state does vision testing at the DMV office or requires you to go to an eye care provider. The DMV page for your renewal type will state this clearly. If your state requires an outside provider, the DMV site usually lists approved optometrists and ophthalmologists, or you can call your local DMV office to ask for a list.

If you already have a regular eye doctor, call them first. They can tell you whether they are approved to do DMV vision tests in your state and what their fee is. If you do not have an eye doctor, search your state's approved provider list or use your vision insurance directory to find someone nearby. Many retail chains like Costco, Walmart, and LensCrafters have in-house optometrists and can often fit you in quickly.

Some states now allow vision tests through online vendors that use video conferencing and automated vision screening tools. These are typically cheaper than in-person exams and faster to schedule, but they are not available in every state and have strict requirements — you usually need a quiet, well-lit space and a computer with a camera. Check your DMV website to see if this option is available where you live.

What happens during the test

The vision test takes about five to ten minutes. You will sit in front of a machine called a phoropter or a chart on the wall, and the examiner will ask you to read lines of letters or numbers that get progressively smaller. They test each eye separately, then both together. They may also ask you to look through different lens strengths to find the one that gives you the clearest vision.

If you wear glasses or contacts, wear them to the test. The examiner will test your vision with your current correction in place, because the test measures how well you see when you are wearing what you normally wear to drive. If you have a new prescription but have not picked up new glasses yet, bring your old ones — the test will use those.

The examiner will also check your peripheral vision and may test your ability to see colors, depending on your state's requirements. Some states test for color blindness because certain types affect your ability to see traffic lights. These additional tests are quick and do not require any special preparation.

Vision standards by state

Every state sets a minimum vision standard for driving. Most require 20/40 vision or better in at least one eye, but some are stricter. A few states require 20/30 in one eye or 20/40 in both eyes. Your state's DMV website will list the exact standard for your state.

If you do not meet the standard with your current glasses or contacts, you have the option to get a new prescription and retake the test. You cannot renew your license until you pass, but you can take the test again as soon as you have new correction. If you fail a second time even with new glasses, some states will restrict your license to daytime driving only or require you to wear corrective lenses at all times — the DMV will tell you what restrictions explore.

If you are color blind, you may still be able to renew your license. Most states do not automatically disqualify color-blind drivers, but some require you to pass a specific color vision test or accept a restriction on your license. Ask the examiner or your DMV office if you are unsure whether color blindness will affect your renewal.

How long vision test results are valid

Most states accept a vision test result for 12 months from the date of the test. This means if you had an eye exam within the past year, you may not need a new test to renew your license — you can bring the old results with you. Check your state's DMV website to confirm how long results are valid in your state, because this varies.

If your vision test is older than your state allows, you will need a new one before you can renew. The DMV will not accept an expired result, even if your vision has not changed. Plan ahead and schedule your eye exam early if you know your current results are about to expire.

What to bring to your vision test

Bring your current glasses or contacts if you wear them. Bring your state ID or another form of identification — the eye care provider will need to verify who you are. If you are going to the DMV for your renewal appointment, bring your renewal notice or appointment confirmation along with your ID.

If you are visiting an eye care provider separately, ask them what documents they need when you schedule. Some providers ask you to fill out a health history form online before your appointment, which speeds up the visit. If you have vision insurance, bring your insurance card so the provider can bill your plan directly.

If you fail the vision test

If you do not meet your state's vision standard, you cannot renew your license until you pass. The examiner will give you a written result showing what you saw and what the standard is. Take this to an eye doctor to get a new prescription or to discuss whether your current glasses or contacts need adjustment.

Once you have new correction, you can retake the vision test. Some states let you retake it at the same location when ready or within a few days. Others require you to wait a set period before retesting. Your DMV office can tell you the rules for your state. You will usually have to pay the test fee again if you retake it at a private provider, though some DMVs do not charge for a retest at the DMV office.

If you fail the test a second time even with new glasses or contacts, talk to an eye doctor about whether there is an underlying vision problem that needs treatment. Some conditions like cataracts or macular degeneration can be managed or corrected, and treating them may help you pass the test on a third attempt.

Frequently Asked Questions

Can I renew my license if I do not have glasses but failed the vision test?

No. You cannot renew until you pass the vision test. If you failed without correction, you will need to get an eye exam and likely a prescription for glasses or contacts. Once you have correction and pass the test, you can complete your renewal.

Do I need a full eye exam or just the vision screening for license renewal?

Most states require only the vision screening — the part where you read the chart. A full eye exam includes additional tests like eye pressure and retinal imaging. Check your state's DMV website to see what is required. If your state requires only screening, you do not have to pay for a full exam.

What if I wear bifocals or progressive lenses?

Wear them to the test. The examiner will test your vision with the correction you actually use for driving. If you have a new prescription for bifocals or progressives, wear those instead of your old single-vision glasses.

How much does a vision test cost?

Vision tests at the DMV are free. If your state requires you to visit an eye care provider, the cost varies — a vision screening alone may cost $25 to $50, while a full eye exam costs $75 to $200 depending on the provider and your location. Vision insurance often covers routine exams, so check your plan.

Can I take the vision test online?

Some states now offer online vision screening through approved vendors, but this is not available everywhere. Check your state's DMV website to see if this option is available. Online tests typically cost less and are faster to schedule, but they have strict technical requirements and may not work for everyone.
