Texas vision requirements for your driver's license

Texas requires you to pass a vision test before you get or renew your driver's license. The test measures how well you can see at a distance, and you must score at least 20/40 in each eye — meaning you can see at 20 feet what a person with typical vision sees at 40 feet. If you wear glasses or contacts, you take the test wearing them, and your license will note that correction is required.

You take the vision test at a Texas Department of Public Safety (DPS) office when you explore for a license or renewal. The test takes a few minutes and is part of the standard process process. If you fail, you have options: you can get glasses or contacts and retake the test, or you may be issued a restricted license depending on your vision and the examiner's judgment.

Key Takeaways

  • Texas requires you to see at least 20/40 in each eye to pass the vision test, whether you wear correction or not.
  • You take the vision test at a DPS office during your license process or renewal, and it takes only a few minutes.
  • If you wear glasses or contacts, you must wear them during the test, and your license will show that correction is required.
  • Failing the vision test does not automatically disqualify you; you can retake it after getting corrective lenses, or you may receive a restricted license.
  • Certain medical conditions that affect vision — such as cataracts, macular degeneration, or severe diabetic retinopathy — may trigger additional review by DPS.

How the vision test works at the DPS office

When you arrive at a DPS office to explore for or renew your license, an examiner will ask you to look into a machine called a vision screener or phoropter. You will read letters or numbers on a chart, starting with larger ones and moving to smaller ones. The examiner records the smallest line you can read clearly in each eye.

The test is quick — usually under five minutes — and you do not need to study or prepare. If you wear glasses or contacts, wear them to the appointment. If you have had recent vision changes or are unsure whether your current prescription is up to date, consider visiting an eye doctor before your DPS appointment. This step is not required, but it can help you pass on your first try.

What happens if you fail the vision test

If you score below 20/40 in either eye, you will not pass the standard vision test. The examiner will tell you this at the time. You have several paths forward.

The most common option is to get glasses or contacts and return to the DPS office to retake the test. There is no waiting period between attempts, so you can schedule another appointment as soon as your new prescription is ready. Bring your new glasses or contacts with you when you return.

In some cases, the examiner may issue you a restricted license — for example, one that limits you to daytime driving only, or requires you to wear corrective lenses. A restricted license is not a temporary measure; it remains in effect until you pass the full vision test or your license expires and you renew it. The examiner will explain any restrictions on your license at the time of issuance.

Vision problems that may require additional review

Certain eye conditions can trigger extra scrutiny from DPS, even if you pass the 20/40 test. These include cataracts, age-related macular degeneration, severe diabetic retinopathy, glaucoma, retinitis pigmentosa, and hemianopia (loss of half the visual field). If you have one of these conditions, DPS may request a report from your eye doctor before issuing your license.

You do not need to report these conditions yourself; DPS identifies them through the vision test or through medical records they may request. If DPS asks for a report, your eye doctor will fill out a form describing your vision and any limitations. This process can add a few weeks to your license process, so plan ahead if you know you have one of these conditions.

Corrective lenses and license restrictions

If you need glasses or contacts to meet the 20/40 standard, your license will include a restriction code that says "Corrective lenses required." This means you must wear your glasses or contacts every time you drive. Driving without them when your license requires them is a violation and can result in a ticket.

Some people also have restrictions for other reasons — for instance, if you have limited peripheral vision, your license might require you to use outside mirrors or restrict you to daytime driving. The examiner will explain any restrictions before you leave the DPS office, and they will appear on your physical license card.

Renewing your license and vision requirements

When you renew your driver's license in Texas, you will take the vision test again. If your vision has changed since your last license, you may need a new prescription before your renewal appointment. If you are renewing online or by mail (which Texas offers for some renewals), you will not take a vision test; you will take one only when you renew in person at a DPS office.

Texas driver's licenses are valid for six or eight years depending on your age. If your vision changes significantly between renewals, you do not have to wait until your license expires to update it. You can visit a DPS office and request a vision retest at any time, though you may need to pay a fee for an out-of-cycle renewal.

Preparing for your vision test appointment

Wear your current glasses or contacts to your DPS appointment if you use them. If you have had recent vision changes or have not had an eye exam in over a year, consider scheduling one with an optometrist or ophthalmologist before your DPS visit. An up-to-date prescription increases your chances of passing the test on your first attempt.

Bring your current license or ID, proof of residency, and proof of Social Security number — the standard documents required for any DPS transaction. Arrive early, as DPS offices can have wait times, and bring a book or phone to pass the time. The vision test itself is brief, but the overall appointment may take an hour or more depending on how busy the office is.

Frequently Asked Questions

What if I wear bifocals or progressive lenses?

Wear them to your vision test. The examiner will test you with the lenses you normally drive in. If your bifocals or progressive lenses are not up to date, consider updating them before your appointment so the test reflects your actual driving vision.

Can I take the vision test without glasses if I do not normally wear them?

Yes. If you do not wear correction, you will take the test without glasses. If you pass 20/40 without correction, your license will have no restriction. If you fail without correction but pass with glasses, your license will require corrective lenses.

What is the difference between 20/40 and 20/20 vision?

20/40 means you see at 20 feet what a person with typical vision sees at 40 feet — your vision is half as sharp. Texas requires 20/40 as the minimum; you do not need 20/20 to get a license. Many people drive safely with 20/40 or even slightly worse vision when corrected.

Do I need a doctor's note to take the vision test?

No. You do not need a doctor's note to take the test at DPS. However, if you have a known eye condition like glaucoma or macular degeneration, DPS may request a report from your eye doctor after you take the test. This is separate from the test itself.

How often do I have to retake the vision test?

You retake the vision test every time you renew your license. In Texas, that is every six or eight years depending on your age. If you fail and need corrective lenses, you can retake it when ready at the same DPS office or at any other DPS location.
