To pass the California vision test for a driver’s license, you need 20/40 vision or better with both eyes tested together, measured on a standard eye chart at the DMV counter. You can wear your glasses or contacts for the test. If you don’t meet the standard, the DMV refers you to an eye doctor rather than denying you outright, and several paths — including a specialized driving test or a restricted license — can still lead to a license as long as your best corrected vision in your better eye is better than 20/200.
How the Screening Works
The DMV uses a standard Snellen eye chart, the same kind used in doctors’ offices. You stand about 20 feet from the chart and read rows of progressively smaller letters. If the wall chart doesn’t work for you, the DMV may switch you to a vision testing machine where you look into a viewer and identify symbols.
The screening measures central visual acuity, meaning how clearly you can see what’s directly in front of you. Peripheral vision matters too, but it mostly comes into play later, in the detailed report an eye doctor fills out if you get referred.
The Vision Standards You Have to Meet
California’s screening standard has two parts, and both must be satisfied:
- 20/40 or better with both eyes tested together.
- 20/40 or better in one eye, with at least 20/70 in the other.
In plain terms, 20/40 means you can read at 20 feet what a person with textbook vision reads at 40 feet. These thresholds apply whether you take the test with or without corrective lenses.1Cornell Law School. Cal. Code Regs. Tit. 13, 20.03 – Vision Screening
There’s also a hard floor. Your best corrected visual acuity must be better than 20/200 in your better eye. If your vision is 20/200 or worse even with glasses or contacts, the DMV cannot issue or renew your license. Bioptic telescopic lenses and similar magnifying devices do not count toward meeting this 20/200 minimum.1Cornell Law School. Cal. Code Regs. Tit. 13, 20.03 – Vision Screening
If You Wear Glasses or Contacts
Bring your glasses or contact lenses to the DMV and take the test with them on. If you pass with corrective lenses, your license will carry a restriction requiring you to wear them whenever you drive.2California State Department of Motor Vehicles. Section 3: The Testing Process – California DMV The restriction appears as a code on the face of your license, and officers can cite you for driving without the required lenses.
If you later have corrective surgery like LASIK and no longer need lenses, you can go back to the DMV, pass the screening without them, and have the restriction removed.
What Happens If You Don’t Pass
Failing the counter screening doesn’t end your application. The DMV gives you a Report of Vision Examination form, known as the DL 62, and refers you to an ophthalmologist or optometrist for a full evaluation.
One detail catches people off guard: the DMV will not issue a temporary license, permit, or extension while you get this evaluation done. You cannot legally drive on expired credentials until the completed DL 62 has been reviewed and the DMV decides your vision condition doesn’t prevent safe driving.3California State Department of Motor Vehicles. Vision Conditions
If you’re renewing and your current license expires before the process finishes, you could face a gap when you can’t legally drive. The simplest way to avoid this is to schedule an eye appointment before your renewal date, especially if you already know your vision has changed.
The DL 62 Report and What the DMV Does With It
The DL 62 has two sections. You fill out Section 1 with your personal information. Your eye doctor completes Section 2, which records your visual acuity and, if you missed the screening standard, a clinical assessment of your vision condition and how it affects your driving. The form must be signed by a licensed optometrist or ophthalmologist and dated within six months of your license application date.1Cornell Law School. Cal. Code Regs. Tit. 13, 20.03 – Vision Screening
You can submit the completed DL 62 in person at a DMV office or upload it through the DMV’s website. Once it’s reviewed, one of several things can happen:
- You’re cleared for a standard license.
- You’re scheduled for a Supplemental Driving Performance Evaluation.
- You’re issued a license with specific driving restrictions.
- You’re denied if your acuity is 20/200 or worse in your better eye even with correction.
The Supplemental Driving Performance Evaluation
When the DL 62 suggests a vision condition could affect driving but doesn’t automatically disqualify you, the DMV may schedule a Supplemental Driving Performance Evaluation, or SDPE. It’s a behind-the-wheel test, but it goes beyond the standard road exam and is built to see whether you can compensate for a vision limitation in real driving conditions.4California Department of Motor Vehicles. Preparing for Your Supplemental Driving Performance Evaluation
During the SDPE, the examiner tests things a routine road test skips over. You’ll receive two instructions at once to see whether you can process and follow both. You’ll do more lane changes than a typical test, which tests your mirror and blind spot checks. The examiner will talk to you while you drive to see whether conversation causes errors. You’ll merge onto a freeway and drive a short distance; if you’d rather not, your license will carry a no-freeway-driving restriction. Finally, you’ll drive a few blocks from the DMV office and find your way back by the same route without help.
Passing the SDPE with a vision condition is genuinely possible. Drivers with monocular vision and other stable conditions pass it regularly by showing they’ve developed habits that compensate, such as more frequent mirror checks and wider head turns.
Restricted Licenses
The DMV doesn’t have to choose between a full license and no license. It can issue one with restrictions tailored to what you can safely handle. Common vision-related restrictions include daylight driving only or no freeway driving. The DMV can also set a shorter license term so your vision is checked again sooner.3California State Department of Motor Vehicles. Vision Conditions
If the DMV thinks your vision could improve — after cataract surgery, for instance — or that your driving skills could improve with practice, it can issue a restricted license or instruction permit that allows additional training while limiting your exposure.
Renewals and Drivers Over 70
Every in-person license renewal includes a vision screening. If you renew online or by mail, you skip the test for that cycle. This matters especially for older drivers: California requires anyone 70 or older to renew in person, which means a vision test at every renewal.5California State Department of Motor Vehicles. Section 13: Seniors and Driving – California DMV Drivers under 70 who are eligible for remote renewal can go several cycles without a formal screening.
Challenging a Denial or Suspension
If the DMV suspends, revokes, or refuses to issue your license based on a vision condition, you can request an administrative hearing to challenge the decision and see the evidence behind it.3California State Department of Motor Vehicles. Vision Conditions At the hearing you can present your own medical evidence, such as a recent DL 62, surgical records showing improvement, or documentation from a low-vision specialist explaining how you compensate.
The hearing is administrative rather than a courtroom trial, but it’s worth preparing seriously. Bring current medical records that address the DMV’s specific concern. A letter from your ophthalmologist explaining why your condition doesn’t impair your driving carries more weight than arguments that you’ve been driving safely for years. If the examiner made an error or your condition has improved since the denial, the hearing is your best route to reverse the decision without starting the whole application over.
