The DMV vision test checks whether your eyesight meets the minimum requirements to legally drive.
In most states, you must have 20/40 vision or better, with or without corrective lenses, to qualify for an unrestricted driverās license.
This guide explains what the DMV vision test is, how to pass it, what eye chart is used, and what happens if you fail, so you know exactly what to expect before your visit.
What Is the DMV Vision Test?
The DMV vision test is a short eye screening required to obtain or renew a driverās license. It evaluates your visual acuity and, in some states, your peripheral (side) vision to ensure you can safely operate a vehicle.
Most DMV vision tests take less than one minute and are performed during your license application or renewal appointment.
DMV Vision Test Requirements (Visual Acuity Standards)
Most states require at least 20/40 vision in one or both eyes to pass the DMV vision test.
This vision can be natural or corrected with glasses or contact lenses.
Requirements vary slightly by state, but the 20/40 standard is the most common threshold for an unrestricted license.
What Does 20/40 Vision Mean?
20/40 vision means you can see at 20 feet what a person with normal vision can see at 40 feet.
If your vision is 20/40, 20/30, or 20/20, you will typically pass the DMV vision test.
What Eye Chart Is Used for the DMV Vision Test?
The DMV vision test typically uses a Snellen eye chart.
Snellen Eye Chart Explained
The Snellen eye chart consists of:
- One large letter at the top
- Multiple rows of progressively smaller letters below.
You will be asked to read the smallest line of letters you can see clearly.
Your visual acuity is determined by the smallest line you can correctly identify.

How to Pass the DMV Vision Test
Most people pass the DMV vision test without difficulty.
If youāre unsure about your eyesight, these steps can help you prepare.
Test Your Vision at Home Before the DMV
You can check your eyesight using a printed eye chart.
If you can clearly read the 20/40 line or smaller, you are likely to pass the DMV vision test.
Home tests are not official, but they are useful for early awareness.
Schedule an Eye Exam If Youāre Unsure
If you struggle to read the chart, schedule an eye exam with an optometrist.
A doctor can:
- Measure your vision accurately
- Update your prescription if needed
- Recommend glasses or contact lenses
Wear Your Prescription Glasses or Contacts
If you normally drive with corrective lenses, wear them during the DMV vision test.
Passing with glasses or contacts is acceptable and common.
Can You Wear Glasses or Contacts During the DMV Vision Test?
Yes, you may wear glasses or contact lenses during the test.
However, if you pass only while wearing corrective lenses, your license will include a restriction requiring you to always drive with glasses or contacts.
You should only wear corrective lenses at the DMV if you also use them while driving.
What Happens If You Fail the DMV Vision Test?
Failing the DMV vision test does not automatically mean you lose your license.
The DMV will review several factors before deciding the next steps.
Possible outcomes after failing include:
Factors the DMV May Consider
- Severity of your visual impairment
- Impact on central and peripheral vision
- Whether the condition affects one or both eyes
- Whether the issue is correctable with lenses or treatment
- Whether the condition may worsen over time
Possible Outcomes After Failing
- Requirement to wear corrective lenses
- Driving restrictions (time, distance, or location)
- Temporary or restricted license
- Referral for a full eye examination
- Vision retest after correction
You may be given a form that must be completed by your eye doctor before returning to the DMV.
