Yes, you can get a driver's license with one eye in all 50 states

Every state allows people with one eye to hold a valid driver's license. The requirement is not two eyes — it is a certain level of visual acuity (how clearly you see) and visual field (how wide your sight range is). If your one eye meets your state's minimum standards, you can get or renew your license. The specific numbers vary by state, but the principle is the same everywhere.

What matters to the DMV is whether you can see well enough to drive safely. A person with one eye that has 20/40 vision or better will usually meet the requirement. A person with one eye that has 20/70 vision might not, depending on their state. The eye you have does not need to be your "dominant" eye — it just needs to pass the test.

Key Takeaways

  • All 50 states allow one-eyed drivers, but each state sets its own minimum vision standard, typically between 20/40 and 20/70 in the better eye.
  • You will take a vision screening at the DMV when you explore or renew; this test measures both how clearly you see and how wide your field of vision is.
  • If you do not meet your state's standard with your current eye, you may be able to retest after vision correction (glasses or contacts) or after medical treatment.
  • Some states require a doctor's report or medical clearance before issuing a license to someone with one eye, so check your state's rules before you go to the DMV.

What vision standard your state actually uses

States do not all use the same number. Most require 20/40 vision or better in at least one eye. Some states allow 20/50 or even 20/60 in certain cases. A few states have a higher bar and require 20/30. The only way to know your state's exact requirement is to check your state's DMV website or call the vision screening office before you explore.

The vision test at the DMV is not the same as an eye doctor's full exam. The DMV uses a machine or chart to measure your visual acuity — how small a line of letters you can read from a set distance. They also check your peripheral vision (side vision), because you need to see hazards coming from the side while driving. If you have one eye, your peripheral vision on one side will be reduced, but that does not automatically disqualify you. The DMV will measure it and compare it to the state standard.

How to prepare for the DMV vision test with one eye

If you wear glasses or contacts, bring them to the DMV. The test measures your vision with correction, not without it. If your one eye sees 20/50 without correction but 20/40 with glasses, you pass. The DMV will test you with your current correction first. If you do not pass, ask whether you can retest after getting a new prescription from an eye doctor.

Before you go to the DMV, consider getting a recent eye exam from an optometrist or ophthalmologist. Bring the results with you. Some states do not require this, but having a doctor's report showing your vision measurement and confirming you are safe to drive can speed up the process. If your vision is borderline, a doctor's letter stating that you have adapted well to monocular vision (one eye) and have safe driving habits can help.

Know your state's specific rules before you arrive. Some states require a medical report or a doctor's sign-off for one-eyed drivers. Others do not. Calling your local DMV office ahead of time takes five minutes and can save you a wasted trip.

What happens if you do not pass the vision test

If your vision does not meet the standard, the DMV will not issue or renew your license. You have options. First, ask the DMV whether you can retest after getting a new eye prescription. Vision can change, and a new pair of glasses might bring you above the threshold. Schedule an appointment with an eye doctor and ask them to focus on getting you the clearest possible correction.

If a new prescription does not help, ask the DMV about a medical review or conditional license. Some states allow a doctor to certify that you are safe to drive despite not meeting the standard vision number. This is more common for people with one eye than for other vision conditions, because monocular vision is a known, stable condition that many people adapt to successfully. The DMV will tell you what documentation the doctor needs to provide.

If you still do not pass, you can appeal the decision in some states. The process and timeline vary. Your state's DMV website will explain the appeal procedure, or you can call the vision screening office to ask.

Medical conditions that might affect your one-eyed license

The reason you have one eye matters less than your current vision and your ability to drive safely. Whether you lost the eye to injury, disease, surgery, or were born with one eye, the DMV tests your vision the same way. However, if your one eye has a condition that is getting worse — like progressive glaucoma or diabetic retinopathy — the DMV may require regular retesting or a doctor's ongoing clearance.

If you have had recent eye surgery or a recent change to your vision, wait until your eye doctor says your vision is stable before going to the DMV. Testing too soon after surgery can give a false result. Ask your doctor when it is safe to be tested for a driver's license.

Restrictions or endorsements on a one-eyed driver's license

Some states add a restriction to your license if you have one eye. Common restrictions include "corrective lenses required" (if you need glasses or contacts) or "daylight driving only" (though this is rare for monocular vision alone). A few states require you to have a side mirror on both sides of your vehicle or to pass a practical driving test. These restrictions vary widely by state.

When you receive your license, read it carefully. If there are restrictions listed, follow them. If you believe a restriction is wrong or unnecessary, you can request a hearing with your state's DMV to challenge it. Bring documentation from your eye doctor supporting your request.

Renewing your license as a one-eyed driver

When your license expires, you will need to pass the vision test again. The standard does not change, and your one eye will be tested the same way. If your vision has remained stable, renewal is usually routine. If your vision has changed — either improved or declined — the test will reflect that. If you have had any eye surgery or medical changes since your last license, tell the DMV staff when you renew.

Some states allow online renewal for people whose licenses are not restricted. If you have a restriction related to your vision, you may need to renew in person so the DMV can retest you. Check your state's renewal rules on the DMV website.

Frequently Asked Questions

Do I need a doctor's letter to get a license with one eye?

Not in all states. Some states require a medical report or eye doctor's clearance; others do not. Check your state's DMV website or call ahead. If your state does not require it, a letter from your eye doctor can still help if your vision is borderline or if you want to document that you are safe to drive.

Will my license say I have one eye?

No. Your license will not state that you have one eye. It may have a restriction like "corrective lenses required" if you need glasses, but monocular vision itself is not listed as a restriction on most licenses. Some states may note it in their internal records, but it will not appear on the card you carry.

Can I drive at night with one eye?

Yes, unless your state or your specific license restriction says otherwise. Monocular vision does not automatically mean you cannot drive at night. However, if your one eye has reduced vision in low light or if you have other eye conditions affecting night driving, the DMV may restrict you to daylight driving. This is determined case by case.

What if I lost my eye after I got my license?

You do not have to report it to the DMV when ready, but you should not drive until you have been tested and know whether you meet the vision standard. Contact your state's DMV to find out whether you need to retest before your next renewal or whether you can wait until renewal. Do not assume your old license is still valid.

Can I get a commercial driver's license with one eye?

Commercial driver's licenses (CDLs) have stricter vision requirements than regular licenses. Most states require 20/40 vision in each eye for a CDL, which means one eye is not enough. Some states may make exceptions for certain types of commercial driving, but this is rare. Contact your state's DMV to ask about CDL rules for monocular vision.
