The California DMV vision test checks whether you can read 20/40 or better with both eyes open, using a standard eye chart or a viewing machine at the counter. You take it every time you renew or apply in person, and you can wear your glasses or contacts while doing it. If you fall short of the standard, the DMV doesn’t deny you on the spot; it sends you to an eye doctor for a formal report, and from there your case can go several different ways.
The Vision Standard You Have To Meet
California’s screening standard has two parts, and both must be satisfied. You need 20/40 or better with both eyes tested together, and you need 20/40 or better in one eye with at least 20/70 in the other. Twenty-forty 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 is also an absolute floor. Your best corrected 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 cannot be used to meet the 20/200 minimum.1Cornell Law School. Cal. Code Regs. Tit. 13, 20.03 – Vision Screening
How the Screening Works at the Counter
The examiner uses a standard Snellen eye chart, the same kind used in most doctor’s offices. You stand roughly 20 feet away and read rows of progressively smaller letters. If reading the wall chart is difficult, the DMV can switch you to a vision testing machine, where you look into a device and identify symbols or letters instead. Either way, the DMV is measuring your central visual acuity: how clearly you can see straight ahead at a distance.
Peripheral vision matters too, but it factors in mainly when a driver is referred for further evaluation rather than during the counter screening itself.
Wearing Glasses or Contacts to the Test
Bring your corrective lenses and take the test wearing them if you normally do. Passing while wearing them means your license will carry a restriction requiring you to wear them behind the wheel.2California State Department of Motor Vehicles. Section 3: The Testing Process – California DMV The restriction appears as a printed code on the face of your license, and law enforcement can cite you for driving without your corrective lenses.
If you later have corrective surgery like LASIK and no longer need lenses, you can return 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 hands you a Report of Vision Examination form, known as the DL 62, and refers you to an ophthalmologist or optometrist for a thorough evaluation. One detail catches many drivers off guard: the DMV does not issue a temporary license, permit, or extension while you get the exam done. Nothing is issued until the completed DL 62 has been reviewed and the DMV decides your vision doesn’t prevent safe driving.3California State Department of Motor Vehicles. Vision Conditions
That gap matters at renewal. If your current license expires before you finish the process, you can be stuck without legal driving privileges for however long it takes. Scheduling an eye appointment ahead of your renewal date is the simplest way to avoid the problem, especially if you already know your vision has changed.
The DL 62 Report of Vision Examination
The DL 62 has two sections. You complete Section 1 with your personal information. Your eye doctor completes Section 2 with your acuity measurements and, if you missed the screening standard, a clinical assessment of your condition and how it affects driving. A licensed optometrist or ophthalmologist must sign and date the form within six months of your license application.1Cornell Law School. Cal. Code Regs. Tit. 13, 20.03 – Vision Screening
You can submit the completed form in person or upload it through the DMV’s website. Once it’s reviewed, a few outcomes are possible. You may be cleared for a standard license. You may be scheduled for a Supplemental Driving Performance Evaluation. You may be issued a license with specific restrictions. If your acuity is 20/200 or worse, you’ll be denied.
The Supplemental Driving Performance Evaluation
When your DL 62 suggests a vision condition could affect driving but doesn’t rule it out, the DMV may schedule a Supplemental Driving Performance Evaluation, or SDPE. This is a behind-the-wheel test built to see whether you can compensate for a vision limitation in real driving conditions, and it goes beyond a standard road test.4California Department of Motor Vehicles. Preparing for Your Supplemental Driving Performance Evaluation
The examiner will test several abilities a normal road test doesn’t emphasize:
- Following two instructions given at the same time.
- Extra lane changes, so the examiner can watch how you check mirrors and blind spots.
- Driving while the examiner talks to you, to see whether distraction produces errors.
- Merging onto a freeway and driving a short distance. If you’d rather skip this portion, your license will carry a no-freeway-driving restriction.
- A short destination trip a few blocks from the DMV, with you finding 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 do it regularly by demonstrating the habits they’ve built to compensate, like frequent mirror checks and wider head turns.
Licenses With Restrictions
The DMV doesn’t have to choose between a full license and no license. It can issue a license with restrictions matched to what you can safely handle. Common vision-related restrictions include daylight-driving-only and no-freeway-driving. The DMV can also shorten your license term so your vision is checked again sooner.3California State Department of Motor Vehicles. Vision Conditions
Vision Testing at Renewal and for Drivers 70 and Older
Every in-person renewal includes a vision screening. Online and mail renewals skip it for that cycle. That distinction matters most 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 qualify for online or mail renewal can go several cycles without a formal DMV vision check. If your eyesight has slipped in the meantime, you may not notice until something happens on the road. A routine eye exam with your own doctor every year or two is worth doing regardless of your renewal method.
Challenging a Denial, Suspension, or Revocation
If the DMV suspends, revokes, or refuses to issue your license because of 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: 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 preparation matters. Bring current medical records that speak directly to the DMV’s stated concern. A letter from your ophthalmologist explaining why your condition doesn’t impair driving carries more weight than an argument that you’ve been driving safely for years. If the examiner made an error or your vision has improved since the denial, the hearing is the fastest route to a reversal without starting the whole application over.
