Texas Vision Requirements at a Glance

Texas requires you to pass a vision test before the Department of Public Safety (DPS) will issue or renew your driver's license. The standard is 20/40 vision or better in each eye, with or without correction (glasses or contacts). If you cannot meet 20/40 in one or both eyes even with correction, you may still be issued a license with restrictions — typically a requirement to wear corrective lenses while driving.

The vision test happens at your local DPS office during your license appointment. You read letters on a chart from a set distance; the examiner records what you can see clearly. This is separate from any eye exam your optometrist or ophthalmologist performs — the DPS test is their own measurement, and you cannot bring results from an outside eye doctor to substitute for it.

If you fail the vision test, you have options: you can correct your vision with glasses or contacts and retake the test the same day at most DPS offices, or you can return on another date. You are not automatically denied a license on the first failed test.

Key Takeaways

  • Texas requires 20/40 vision or better in each eye, measured at the DPS office during your appointment — you cannot use an outside eye exam result.
  • Glasses and contacts count toward meeting the standard; if you need them to see 20/40, you must wear them while driving and your license will be marked with a restriction code.
  • If you fail the vision test, you can correct your vision and retake it the same day at most DPS locations without rescheduling.
  • Vision restrictions on your license are enforceable; driving without required corrective lenses is a violation and can result in a ticket.
  • Certain medical conditions that affect vision — such as cataracts, macular degeneration, or severe diabetic retinopathy — may result in denial or additional restrictions beyond standard correction requirements.

How the Vision Test Works at the DPS Office

When you arrive for your license appointment, the DPS examiner will conduct a vision screening using a Snellen chart or similar eye chart. You stand at a marked distance (usually 20 feet) and read letters of decreasing size. The examiner tests each eye separately, then both eyes together. The result is recorded as a fraction — 20/40 means you can see at 20 feet what a person with standard vision sees at 40 feet.

You will be asked whether you wear glasses or contacts. If you do, you must wear them during the test — this is the corrected vision measurement. If you wear them only sometimes, tell the examiner; they may test you both with and without correction to document your uncorrected vision as well. The DPS uses this information to determine whether a restriction code is necessary on your license.

The entire vision test takes a few minutes. If you pass (20/40 or better in each eye), the examiner notes this on your file and you move forward with the rest of your license process. If you do not pass, the examiner will tell you your result and explain your options.

What Happens If You Do Not Meet the 20/40 Standard

Failing the vision test does not automatically mean you cannot get a license. Texas offers two paths forward: correction and retesting, or a restricted license.

If you do not have glasses or contacts with you, most DPS offices allow you to leave, obtain corrective lenses, and return the same day to retake the test. You do not need to reschedule or pay an additional fee for the retest. If you already wear correction but still cannot reach 20/40, you can still retake the test on another date — there is no limit to the number of times you can test, though you will need to schedule a new appointment and pay the process fee again.

If you cannot meet 20/40 even with the best available correction, DPS may issue a restricted license with a notation that you must wear corrective lenses while driving. The restriction code appears on the front or back of your license and is visible to law enforcement during a traffic stop. Driving without the required lenses is a violation and can result in a citation.

Restriction Codes and What They Mean on Your License

If your vision test shows you need corrective lenses to drive safely, your Texas license will carry a restriction code. The most common code is B — Corrective Lenses Required. This means you must wear glasses or contacts every time you drive, regardless of the distance or lighting conditions.

Other vision-related codes exist for specific conditions. For example, if you have limited peripheral vision or other field-of-vision issues, you may receive a code requiring outside mirrors or restricting night driving. These are less common and typically result from a medical evaluation rather than a standard vision test failure.

The restriction code is printed on your license and is legally enforceable. A police officer can cite you for driving with a restriction violation — for instance, driving without glasses when code B is on your license. This citation can result in a fine and points on your driving record.

Medical Conditions That Affect Vision Clearance

Beyond the standard 20/40 measurement, certain eye diseases and conditions can result in license denial or additional restrictions. These include advanced cataracts, macular degeneration, severe diabetic retinopathy, advanced glaucoma, and retinitis pigmentosa (a progressive vision loss condition). If you have any of these diagnoses, DPS may require a medical report from an eye specialist before issuing your license.

You are not required to volunteer this information during a routine vision test — the examiner can only measure what they see on the chart. However, if you disclose a condition or if the examiner observes signs of a serious eye problem during the test, they may refer you for a medical evaluation. This evaluation is conducted by an eye doctor of your choice, and you must submit their report to DPS before a license decision is made.

The medical evaluation does not automatically deny you a license. Instead, it documents your condition and allows DPS to make an informed decision about whether restrictions are necessary or whether you should not be licensed to drive. If you disagree with a denial based on a medical evaluation, you have the right to request a hearing before the DPS.

Renewing Your License: Vision Requirements Stay the Same

When you renew your Texas driver's license, you must pass the vision test again. The standard does not change — you still need 20/40 or better in each eye. If your vision has changed since your last license, this is when DPS will catch it and may add or modify restrictions.

If you currently have a restriction code for corrective lenses and your vision has improved (for example, you had cataract surgery), you can request that the restriction be removed during renewal. You will need to pass the vision test without the restriction code being applied — meaning you must meet 20/40 without the restriction notation. If you still need correction, the code will remain.

Renewal appointments include the vision test as part of the standard process. You cannot renew by mail or online in Texas if you have a restriction code; you must appear in person at a DPS office so the examiner can conduct the vision test.

Preparing for Your Vision Test

If you wear glasses or contacts, bring them with you to your DPS appointment. Wear them during the test — this is how DPS measures your corrected vision. If you have recently changed your prescription, consider having your eye doctor confirm the new prescription is correct before your appointment; a slightly outdated prescription could cause you to fail the test unnecessarily.

If you do not currently wear correction but suspect you might need it, consider scheduling an eye exam with an optometrist or ophthalmologist before your DPS appointment. This is not required, but it gives you the option to obtain glasses or contacts before you test, rather than failing and having to return later. Many DPS offices have optical shops nearby or can direct you to one if you need same-day correction.

On the day of your appointment, make sure you are well-rested and not fatigued — eye strain can affect your test result. Arrive a few minutes early so you are not rushed. Let the examiner know if you have any eye conditions or recent eye surgery; this helps them interpret your results accurately.

Frequently Asked Questions

Can I use my eye doctor's vision test result instead of taking the DPS test?

No. DPS conducts its own vision test at the office; results from an outside eye exam cannot substitute for it. However, if DPS refers you for a medical evaluation due to a suspected eye condition, that evaluation must come from an eye doctor and be submitted to DPS.

What if I wear bifocals or progressive lenses?

Wear them during the vision test. DPS tests you as you would normally see while driving. If your bifocals or progressive lenses allow you to meet 20/40, you will pass. If they do not, you may need an updated prescription or a different lens type.

Can I get a license if I am blind in one eye but have 20/20 in the other?

Yes, as long as your sighted eye meets 20/40 or better. Texas measures each eye separately, so if one eye is blind or below 20/40 and the other meets the standard, you can be licensed. You may receive a restriction code noting the vision in one eye, depending on DPS policy at the time of your test.

What if I fail the vision test and cannot afford glasses right away?

You can reschedule your appointment for a later date and obtain glasses before returning. You will need to pay the process fee again for the new appointment. Some community health centers and charitable organizations offer low-cost or free eye exams and glasses; your local health department can direct you to these resources.

Do I have to retake the vision test every time I renew my license?

Yes. Vision requirements explore to every license issuance and renewal in Texas. If your vision has changed, DPS will detect it during renewal and may add or remove restrictions accordingly.
