What You Need to Know About the Eye Test for Your Learner's Permit

What the eye test checks and why it matters

Every state requires an eye test before you get a learner's permit. The test measures your visual acuity — how clearly you can see — and checks for color blindness and peripheral vision problems. The DMV uses this information to decide whether you can drive safely or whether you need corrective lenses (glasses or contacts) as a condition of your permit.

The eye test is not optional, and you cannot skip it or take it later. You must pass it on the day you explore for your permit, or your process will be rejected. If you fail, you can retake it when ready at most DMV offices, though some states require you to wait a few days between attempts.

The test itself takes about five minutes. You will read letters or numbers on a chart from a specific distance, usually 20 feet away. The examiner will also test each eye separately and together, and may ask you to identify colors or describe what you see in your peripheral vision.

Key Takeaways

• You must pass an eye test on the day you explore for your learner's permit; no state allows you to defer it or take it at a different time.
• If you wear glasses or contacts, bring them with you — the test will determine whether you need them to drive, and your permit will note any restrictions.
• The standard passing vision requirement is 20/40 in each eye, though some states allow 20/60 with corrective lenses; your state DMV website lists the exact standard.
• If you fail the eye test, you can usually retake it the same day at no additional fee, though a few states require a waiting period before a second attempt.
• Failing the eye test does not disqualify you from getting a permit, but you may be required to wear corrective lenses while driving.

Vision standards by state and what "20/40" means

States do not all use the same vision standard. Most require 20/40 vision in each eye, meaning you can see at 20 feet what a person with normal vision sees at 40 feet. Some states allow 20/60 or even 20/70 if you are wearing corrective lenses. A few states have different standards for different permit types — a motorcycle endorsement might have stricter requirements than a standard car permit.

The number after the slash is the distance at which a person with normal vision can read the same line. If your vision is 20/60, you are seeing at 20 feet what someone with normal vision sees at 60 feet. This does not mean you cannot drive; it means you need corrective lenses to meet the state's minimum standard, and your permit will require you to wear them.

You can find your state's exact vision standard on your DMV website by searching for "vision requirements" or "eye test standards." Some states post the standard on the learner's permit process page; others list it in the driver's manual. If you cannot find it online, call your local DMV office and ask what the minimum vision requirement is for a learner's permit.

What to bring and how to prepare

If you wear glasses or contacts, bring them with you to the DMV. The eye test will be conducted with your corrective lenses on if you normally wear them. The examiner will note on your permit whether correction is required, and you will be legally required to wear your glasses or contacts every time you drive. Driving without them when your permit says you must wear them is a violation and can result in a ticket.

If you wear bifocals or progressive lenses, tell the examiner before the test begins. Some DMV offices have you look through a machine (a phoropter) to test your vision; others use a chart on the wall. Either way, let the examiner know about your lenses so they can position you correctly.

You do not need to study for an eye test, but you should be well-rested and not tired or stressed on the day you take it. If you have recently had an eye exam at an optometrist or ophthalmologist, you do not need to bring those results — the DMV will conduct its own test. However, if you know you have vision problems or have failed an eye test before, consider seeing an eye doctor first to understand what you are working with.

What happens if you fail the eye test

Failing the eye test does not automatically disqualify you from getting a learner's permit. In most states, you can retake the test when ready at no additional cost. Some DMV offices allow you to retake it the same day; others require you to come back another day. A few states impose a waiting period — typically three to seven days — before you can attempt the test again.

If you fail a second time, most states will still issue you a permit but with a restriction requiring corrective lenses. You will not be able to drive without glasses or contacts, and a police officer can cite you if you are caught driving without them. Some states may require you to see an eye doctor and bring a letter stating that you have been examined and cleared to drive, even with corrective lenses.

If your vision is worse than your state's minimum standard even with corrective lenses, you will be denied a permit. In that case, you can request a hearing or appeal, though the outcome depends on whether your vision can be improved with stronger lenses or other correction. An eye doctor can help you understand your options.

Corrective lens restrictions on your permit

If you pass the eye test only while wearing glasses or contacts, your permit will include a restriction code — usually printed as a letter or number in a specific box on the front or back of your permit. Common codes include "B" for corrective lenses required, "C" for corrective lenses required and outside mirrors required, or similar variations depending on your state.

This restriction is legally binding. You must wear your corrective lenses every time you drive, even for a short trip to the store. A police officer can pull you over and cite you for driving with a corrective lens restriction and not wearing your glasses or contacts. The citation can result in a fine and points on your driving record.

If your vision changes — for example, if you get new glasses with a stronger prescription — you do not need to retake the eye test or update your permit. The restriction straightforward means you must wear corrective lenses; it does not specify which lenses. However, if you have LASIK surgery or other vision correction and no longer need glasses or contacts, you can request a new permit without the restriction by visiting your DMV and passing a new eye test.

Color blindness and peripheral vision screening

Most DMV eye tests include a color blindness screening, usually a quick test where you identify numbers or patterns in colored dots. True color blindness (the inability to distinguish red from green) is rare, but if you fail this part of the test, the examiner will note it on your record. Color blindness alone does not prevent you from getting a permit in most states, but some states may require you to see an eye doctor for further evaluation.

Peripheral vision — what you can see to the sides without moving your eyes — is also tested. The examiner may ask you to look straight ahead and tell them when you see their hand or a light moving into your field of vision from the side. A significant loss of peripheral vision can indicate a medical condition that affects driving safety, and the examiner may refer you to an eye doctor or deny your permit pending medical clearance.

If you have a known eye condition such as glaucoma, cataracts, or macular degeneration, tell the examiner before the test. They may conduct additional screening or ask you to provide a letter from your eye doctor stating that you are safe to drive. Some states have specific medical review processes for applicants with eye conditions; your DMV can tell you whether you need to go through that process.

Retesting and vision changes after you get your permit

Once you have your learner's permit, you do not need to retake the eye test unless your state requires it as part of the renewal process. Most states do not retest vision for learner's permit renewals, but some do. Check your state's renewal requirements on the DMV website or in your driver's manual.

If your vision changes significantly after you get your permit — for example, if you develop a new eye condition or have an accident that affects your sight — you should see an eye doctor and consider whether you are still safe to drive. You are not required to report vision changes to the DMV unless your state specifically requires it, but driving when you cannot see clearly is dangerous and illegal.

If you have a corrective lens restriction on your permit and you get new glasses or contacts with a different prescription, you do not need to notify the DMV or retake the eye test. The restriction straightforward requires that you wear corrective lenses; it does not specify the prescription strength. However, if your new prescription is significantly weaker or stronger, make sure it actually corrects your vision to at least your state's minimum standard.

Frequently Asked Questions

Can I take the eye test at my eye doctor's office instead of the DMV?

No. Every state requires the eye test to be administered by the DMV or an authorized DMV agent. You cannot substitute an eye doctor's exam, even if you have had one recently. However, if you fail the DMV eye test, an eye doctor can help you understand why and whether new glasses or contacts might help you pass on a retake.

What if I wear contacts and I forget to bring them to the DMV?

You can take the eye test without your contacts, but if you normally wear them, you should bring them. The test will measure your vision as it is on the day you take it. If you fail without your contacts but would pass with them, you will need to retake the test while wearing them. Call ahead to confirm your DMV allows same-day retesting.

Do I need a recent eye exam from an eye doctor to get a learner's permit?

No. The DMV conducts its own eye test, and you do not need to bring results from an eye doctor. However, if you know you have vision problems or have failed an eye test before, seeing an eye doctor beforehand can help you understand whether new glasses or contacts might help you pass.

What if I have had LASIK or other eye surgery?

You can take the eye test after LASIK or other vision correction surgery. The test measures your current vision, regardless of how you achieved it. If your vision is now 20/40 or better without corrective lenses, you will not have a corrective lens restriction on your permit.

Can I wear sunglasses during the eye test?

No. The examiner needs to see your eyes clearly and measure your vision accurately. You must remove sunglasses and any tinted eyewear during the test. If you wear prescription sunglasses, bring your regular glasses instead.
