Yes, you can get a driver's license with one eye in all 50 states, but you will need to meet your state's vision standards and may face restrictions on your license.

Every state sets its own vision requirements for drivers, and those requirements focus on what you can actually see — your visual field and acuity — rather than how many eyes you have. A person with one eye who meets the vision standard can be licensed. However, some states add restrictions to the license itself, such as requiring glasses, prohibiting night driving, or limiting highway speeds. The restrictions depend on your specific vision measurement and your state's rules.

The key number is your visual acuity — how clearly you see. Most states require at least 20/40 vision in your better eye (or both eyes combined if you wear correction). Some states are stricter and require 20/30. A few are more lenient and allow 20/60. You will take an eye test at the DMV or an eye doctor's office, and that test will determine whether you meet the threshold and what restrictions, if any, your state will impose.

Key Takeaways

  • All 50 states allow people with one eye to hold a driver's license if their vision meets the state's minimum standard, usually 20/40 or better in the better eye.
  • Your state's DMV will test your vision and may add restrictions to your license, such as corrective lenses, daylight-only driving, or speed limits.
  • Some states require a doctor's statement or a special medical evaluation before issuing a license to someone with one eye.
  • Restrictions vary widely by state — what is allowed in one state may be prohibited in another, so check your specific state's rules before explore.

How states measure vision for one-eyed drivers

When you have one eye, the DMV tests the vision in that eye alone. The standard eye chart you sit in front of shows letters that get smaller as you move down. You read them from a set distance — usually 20 feet — and the result is expressed as a fraction. A score of 20/40 means you see at 20 feet what a person with standard vision sees at 40 feet. Most states accept 20/40 as the minimum; some require 20/30 or better.

If you wear glasses or contact lenses, you will be tested both with and without correction. Most states care about your corrected vision — what you see when wearing your prescription. If your corrected vision meets the standard, you can be licensed, but your license will carry a restriction requiring you to wear those glasses or contacts while driving.

A few states also test your visual field — the width of the area you can see without moving your eyes. Losing one eye reduces your peripheral vision on one side. Some states have a minimum field requirement (often 140 degrees or wider), while others do not. If your field is narrower than the state standard, you may be denied or restricted.

What restrictions states commonly add to one-eyed drivers' licenses

A restriction on your license is a condition you must follow while driving. Common restrictions for one-eyed drivers include a requirement to wear corrective lenses, a prohibition on driving at night or in low light, a speed limit lower than the posted limit, or a requirement to use outside mirrors. Some states restrict driving to daylight hours only or to roads you know well.

Not all states add restrictions to one-eyed drivers who meet the vision standard. Some states have no special restrictions at all — if you pass the vision test, you get an unrestricted license. Other states are more cautious and routinely add one or more restrictions. A few states require a medical evaluation or a letter from your eye doctor before they will issue any license to a one-eyed driver, even if vision is adequate.

The restrictions are not permanent. If your vision changes or if you later lose the sight in your other eye, you will need to retake the test. Some states also allow you to request a reassessment if you believe the restrictions are no longer necessary — for example, if you have adapted well to driving with one eye and your eye doctor supports removing the nighttime restriction.

State-by-state variation in one-eye driver rules

Because each state sets its own standards, the rules differ significantly. California, for example, requires 20/40 vision and does not automatically restrict one-eyed drivers, though the DMV may add restrictions based on the individual case. New York requires 20/40 and may restrict to daylight driving. Florida requires 20/40 and typically does not add restrictions if vision is adequate. Texas requires 20/40 and may restrict based on visual field.

Some states have published guidelines for one-eyed drivers; others handle each case individually. A few states require a formal medical report from an ophthalmologist or optometrist before processing the process. Others accept the DMV's own vision test as sufficient. The only way to know your state's exact rules is to contact your state's DMV directly or visit its website — the rules are not standardized, and what applies in one state does not explore in another.

If you are moving to a new state or renewing your license in a state where you have not driven before, bring documentation of your vision test results and any medical reports from your eye doctor. Some states will accept these documents; others will require you to take their own test. Having the paperwork ready speeds up the process.

how the process works for a license with one eye

Start by contacting your state's DMV to ask about the specific process for one-eyed drivers. Many states have a standard process form, but some require additional paperwork — a medical report, a letter from your eye doctor, or a statement about how long you have been driving with one eye. The DMV can tell you what documents to bring before you go in.

Schedule a vision test at the DMV or at an approved eye doctor's office, depending on your state's rules. Bring your current ID, proof of residency, and any medical documentation your state requires. Wear your corrective lenses if you use them — the test will measure your corrected vision. The test itself takes 10 to 15 minutes.

After the test, the DMV will review the results against your state's standards. If you meet the vision requirement, you will be issued a license. Any restrictions will be printed on the license itself — for example, "Corrective lenses required" or "Daylight driving only." You are legally required to follow those restrictions. If you do not meet the standard, the DMV will deny the process and explain why. You can request a reassessment after a set period, usually 30 to 90 days, if your vision has improved or if you believe the test was inaccurate.

What to do if your process is denied

If the DMV denies your process, ask for a written explanation of the reason. The most common reason is that your vision does not meet the state's minimum standard. If that is the case, you have a few options: you can wait and reapply after your eye doctor confirms your vision has improved, you can request a reassessment by a different examiner or at a different DMV office, or you can ask your eye doctor whether a change in your prescription might help you meet the standard.

Some states allow you to appeal a denial through a formal process. Contact your state's DMV to ask whether an appeal is available and what the important date is. An appeal usually involves submitting additional medical evidence or requesting a hearing before a DMV official. If you have documentation from your eye doctor supporting your case — for example, a report showing your vision is better than the initial test indicated — include it with your appeal.

If you are denied in your state but believe the denial is incorrect, you can also consult an eye doctor who specializes in driving vision. They can perform a more detailed evaluation and may be able to provide a report that supports your case in an appeal or a reapplication.

Frequently Asked Questions

Do I have to tell the DMV I have one eye, or will they find out during the vision test?

The vision test will reveal that you have one eye because the examiner will test each eye separately. You should disclose it on your process form if asked, but the test itself will make it clear. Some states ask directly on the form whether you have any vision or medical conditions; answer honestly.

If I lose my other eye after getting a license, what happens?

You must notify your state's DMV when ready. Your license will be suspended or revoked, and you will not be able to drive legally. You can reapply only if your vision is restored or if you receive a medical device that restores functional vision. Most states do not allow driving with no usable vision in either eye.

Can I drive at night if I have one eye and my license does not say "daylight only"?

Yes, if your license does not carry a nighttime restriction, you are permitted to drive at night. However, driving with one eye at night is more challenging because you have reduced peripheral vision and depth perception. Use extra caution, drive slower than you normally would, and consider whether you are comfortable with the risk.

Will my insurance rates go up if I have one eye?

Insurance rates depend on your driving record and claims history, not on the number of eyes you have. However, if your license carries restrictions (such as daylight-only driving), you should disclose that to your insurance company. Some insurers may adjust rates based on restrictions, but many do not.

How often do I need to renew my vision test if I have one eye?

That depends on your state and your age. Most states require vision retesting at license renewal, which is typically every 4 to 8 years. Some states require more frequent testing for drivers over 70 or for drivers with medical conditions. Check your state's renewal schedule when you receive your license.
