Yes, you can get a driver's license with one eye in most U.S. states, but you will need to meet specific vision standards and may face restrictions on where and when you can drive

A single eye does not automatically disqualify you from holding a driver's license. What matters to your state's Department of Motor Vehicles (DMV) is whether your vision meets the minimum acuity requirement — typically 20/40 or better in your remaining eye, though this varies by state. Some states allow you to drive with monocular vision (vision in one eye only) without restriction. Others permit it but add conditions, such as requiring you to wear corrective lenses, limiting you to daytime driving, or restricting highway speeds. A few states have stricter rules and may deny licensure or require a medical evaluation before deciding.

The key is that your state's DMV will test your vision during the licensing process. If you have one eye, you will take the same vision test as anyone else, but the examiner will test only the eye you have. If that eye meets the standard, you move forward. If it does not, you may be denied unless you can correct it with glasses or contacts.

Key Takeaways

  • Most states allow one-eyed drivers if the remaining eye meets the minimum vision standard, usually 20/40 or better.
  • Some states impose restrictions such as daytime-only driving, corrective lens requirements, or speed limits on monocular licenses.
  • You will need to pass the vision test at your DMV with your one eye; corrective lenses can help you meet the standard if needed.
  • A few states require a medical report or eye doctor's statement before issuing a license to someone with monocular vision.
  • Restrictions and standards differ significantly by state, so you must check your specific state's rules before explore.

How states set vision standards for one-eyed drivers

The National Highway Traffic Safety Administration (NHTSA) does not set a single federal vision standard for drivers. Instead, each state establishes its own minimum acuity requirement. Most states use 20/40 as the threshold — meaning you can see at 20 feet what a person with standard vision sees at 40 feet. Some states are more lenient and accept 20/50 or 20/60. A handful require 20/30 or better.

When you have one eye, the DMV tests that eye alone. If your single eye meets your state's standard, you will typically receive an unrestricted license. If it does not meet the standard but can be corrected with glasses or contact lenses to meet it, you will receive a license with a restriction requiring you to wear correction while driving.

The reason states focus on acuity rather than the number of eyes is that visual acuity — sharpness of sight — is what allows you to read road signs, see pedestrians, and judge distance. Depth perception, which requires two eyes, is a secondary concern in most state regulations, though some states do test for it or note its absence on your license.

Restrictions commonly placed on monocular licenses

States that allow monocular driving often add conditions to the license. These restrictions appear on your license itself and are legally binding. Common restrictions include:

  • Corrective lens requirement: You must wear glasses or contacts while driving, even if you do not need them for other activities.
  • Daytime driving only: You may drive only between sunrise and sunset, or only during daylight hours.
  • Speed restrictions: You may be limited to speeds below 45 mph or prohibited from highway driving.
  • No freeway driving: Some states restrict monocular drivers from interstate highways or divided highways.
  • Regular medical review: Your license may require renewal more frequently than standard licenses, with vision re-testing at each renewal.

Not all states use all of these restrictions. Some states impose none at all. Others use a combination. The restrictions depend on your state's policy and sometimes on the specific circumstances of your case — for example, whether you lost the eye recently or have had monocular vision for years.

State-by-state variation in monocular vision rules

Because each state sets its own standards, the rules differ significantly. Some states have published clear policies on monocular driving. Others handle each case individually, which means the outcome can depend on the specific DMV office or examiner you encounter.

States generally fall into three categories. The first group — including California, Florida, and New York — allows monocular driving with minimal or no restriction, provided the remaining eye meets the vision standard. The second group allows it but adds restrictions such as daytime-only driving or corrective lens requirements. The third group requires a medical evaluation, a letter from an eye doctor, or a formal information before issuing a license.

Because variation is significant and rules can change, you should contact your state's DMV directly or visit its website before you go in for testing. Ask specifically whether monocular vision is permitted and what restrictions, if any, explore. Some states have a form you can submit in advance with documentation from your eye doctor, which can speed up the process.

What to bring to the DMV if you have one eye

When you go to the DMV to get or renew a license, bring your standard documents: proof of identity, proof of residency, and your Social Security number or tax ID. If you have one eye, you may also want to bring documentation from your eye doctor, even if your state does not require it.

A letter from your ophthalmologist or optometrist stating your current vision acuity, the reason for monocular vision (if recent), and any relevant medical history can help the DMV process your process more smoothly. This is especially useful if your state requires a medical evaluation or if you are concerned that the vision test might be unclear due to the circumstances of your case.

Some states have a specific form for medical reports related to vision or driving fitness. Check your state's DMV website to see if such a form exists. If it does, ask your eye doctor to complete it and bring it with you. If your state does not have a form, a standard letter from your doctor will usually suffice.

What happens if you fail the vision test

If your one eye does not meet your state's minimum vision standard, you will not automatically be denied a license. Instead, you have options. First, you can ask for a retest — sometimes a second attempt yields a different result, especially if you were nervous or the lighting was poor. Second, you can get corrective lenses (glasses or contacts) and return for another test. Many people with one eye can meet the standard with correction.

If you still cannot meet the standard even with correction, your state may deny you a license, or it may issue a restricted license for certain purposes (such as farm driving in rural areas). Some states also allow you to request a hearing or appeal if you believe the test was administered incorrectly or if you have new medical information.

If you are denied, ask the DMV for the specific reason in writing. This gives you clarity on what to address — whether it is vision acuity, a medical condition, or something else — and helps you decide whether to pursue an appeal or retest.

Driving with monocular vision: practical and legal considerations

Even if you receive a license, driving with one eye presents real challenges beyond what the vision test measures. You lose depth perception, which affects your ability to judge the distance of oncoming vehicles, the gap between your car and others, and the height of obstacles. You have a blind spot on the side of your missing eye, which means you cannot see vehicles or pedestrians in that area without turning your head.

If your license has restrictions, follow them strictly. Driving outside the restrictions — for example, driving at night when your license says daytime only — is a violation and can result in fines, license suspension, or liability issues if you are in an accident. Insurance companies may also deny a claim if you were driving in violation of your license restrictions.

Consider taking a defensive driving course designed for drivers with vision loss. Some organizations and driving schools offer these courses, and they teach techniques for compensating for monocular vision, such as head positioning, mirror use, and speed adjustment. Some insurance companies offer discounts for completing such a course.

Frequently Asked Questions

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

It depends on your state. Some states require a medical report or eye doctor's statement before issuing a monocular license. Others do not require it but will accept it if you provide it. Contact your state's DMV to find out whether a letter is required or recommended. If it is recommended, getting one in advance can speed up the process.

Will my insurance company cover me if I have a monocular license?

Most insurance companies will cover you if you have a valid license, including a monocular license with restrictions. However, some may charge higher premiums or require you to disclose the monocular vision. Tell your insurance company about your license restrictions so there are no surprises if you file a claim. If you violate your license restrictions, the insurer may deny coverage.

Can I drive on the highway with one eye?

It depends on your state and your specific license restrictions. Some states allow unrestricted highway driving for monocular drivers. Others prohibit it or limit it to certain speeds. Check your license to see if there are restrictions listed. If you are unsure, contact your state's DMV or ask the examiner when you take your test.

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

You are not required to report the loss to the DMV when ready, but you should inform them before your next renewal or if you are pulled over. When you renew, you will take the vision test again, and the DMV will determine whether your remaining eye meets the standard. If it does, you will receive a new license. If it does not, you may need to pursue a restricted license or appeal.

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 monocular vision typically disqualifies you. Some states may make exceptions with a medical waiver, but this is rare. If you need a CDL, contact your state's DMV to ask about waivers or alternative options.
