The California DMV vision test requires you to read the 20/40 line with both eyes open, plus 20/40 in one eye and at least 20/70 in the other. You can wear your glasses or contacts during the screening, and if you need them to pass, your license will carry a corrective lenses restriction. Fall short of 20/40 and you’re not automatically denied. The DMV sends you to an eye specialist, reviews the results, and may still issue you a restricted license.
The Two Vision Thresholds
There are really two numbers to know. The first is the 20/40 screening standard used at the counter.1California Department of Motor Vehicles. Vision Impairment and DMV Requirements In practical terms, 20/40 means you can read from 20 feet what someone with unimpaired vision reads from 40 feet.
The second is a statutory floor. California Vehicle Code Section 12805 provides that if your best corrected acuity is 20/200 or worse in your better eye, the DMV cannot issue you a license. The same statute prohibits using bioptic telescopic lenses to meet that 20/200 threshold.2California Legislative Information. California Code VEH 12805 – Issuance and Renewal of Licenses Anything between 20/40 and 20/200 lands you in the discretionary zone, where a specialist evaluation and possibly a driving test decide the outcome.
When You Have to Take It
You take the vision screening at the counter any time you apply for a new California license, including transfers from another state, and at every in-person renewal.3California Department of Motor Vehicles. California Driver Handbook – The Testing Process Drivers who qualify for online or mail renewal can sometimes skip the in-person screening for that cycle.
One age rule matters most: if you are 70 or older when your license expires, you must renew in person and pass a vision test. Online and mail renewal are not available.4California Department of Motor Vehicles. California Driver Handbook – Seniors and Driving Every renewal after 70 includes a mandatory in-person vision check.
What to Bring to the DMV
If you wear glasses or contacts for distance vision, bring them. Your result with corrective lenses is what counts, and forgetting them means testing with uncorrected vision and risking an unnecessary failure.
You can also see your own eye doctor beforehand. Your optometrist or ophthalmologist can complete a Report of Vision Examination (Form DL 62), which records acuity for each eye and both eyes together.5California Department of Motor Vehicles. Report of Vision Examination – DL 62 The exam must have been conducted within the last six months, and the doctor must sign the form and include their license number. Bringing a completed DL 62 to the counter gives the DMV verified clinical data and can speed things along if you have a known vision condition.
What the Screening Looks Like
The test is quick. A technician directs you to read a row of letters or numbers from a set distance, either on a wall-mounted Snellen chart or through a machine you look into like binoculars. You read first with both eyes open, then cover one eye and read again, then switch.
The technician is checking central acuity in each eye and both together. Hit the 20/40 line with both eyes and at least 20/70 in your weaker eye, and you pass and move on to the rest of your application.1California Department of Motor Vehicles. Vision Impairment and DMV Requirements
Restrictions That May Appear on Your License
If you passed while wearing glasses or contacts, the DMV prints a corrective lenses restriction on your license.3California Department of Motor Vehicles. California Driver Handbook – The Testing Process That restriction means your license is only valid when you’re wearing your corrective lenses, and driving without them is a citable violation.
Depending on your situation, the DMV can impose other vision-related restrictions. These might include limiting you to daytime driving, requiring extra mirrors, or keeping you off freeways.6California Department of Motor Vehicles. California Driver Handbook – Driver Safety Each restriction is tailored to the condition, with the goal of letting you drive within safe boundaries rather than pulling your license.
If You Don’t Pass
Failing the counter screening isn’t the end. The DMV hands you a blank DL 62 and sends you to an eye specialist for a full examination.3California Department of Motor Vehicles. California Driver Handbook – The Testing Process Your optometrist or ophthalmologist examines your acuity, visual fields, and any underlying conditions, then documents everything on the form. If your vision isn’t correctable to 20/40 in each eye, or there’s possible visual field loss, the doctor must also perform a full visual field examination.5California Department of Motor Vehicles. Report of Vision Examination – DL 62 You bring the completed form back, and a DMV analyst reviews the findings.
Based on that review, the DMV may require a Supplemental Driving Performance Evaluation, or SDPE. This is a behind-the-wheel test designed for drivers with vision conditions or other physical or mental conditions that could affect driving safety.7California Department of Motor Vehicles. Preparing for Your Supplemental Driving Performance Evaluation The examiner evaluates how you handle lane changes, follow directions, and maintain concentration in real traffic. The point is to see how you actually compensate for reduced vision, not just whether you can read a chart.
Restricted Licenses and Shorter Terms
If you pass the SDPE, the DMV may issue a restricted license instead of an unrestricted one. Common restrictions include daytime-only driving, which keeps you off the road during low-light hours when reduced acuity is most dangerous. You may also receive a limited-term license that expires sooner than the standard five years, so the DMV can monitor whether your condition is stable.1California Department of Motor Vehicles. Vision Impairment and DMV Requirements Drivers with progressive conditions may be required to submit to more frequent vision screenings on a schedule the DMV sets.8Cornell Law Institute. California Code of Regulations Title 13 Section 20.03 – Vision Screening
If Your Application Is Denied
If the DMV concludes your vision doesn’t allow safe driving even with restrictions, your application will be denied. The hard line applies here: corrected acuity of 20/200 or worse in your better eye is an automatic disqualification under state law, and bioptic telescopic lenses cannot be used to reach that threshold.2California Legislative Information. California Code VEH 12805 – Issuance and Renewal of Licenses Between 20/200 and 20/40, the DMV has discretion, and your specialist’s report, the SDPE results, and the nature of your condition all factor in. If you believe the decision was wrong, you can request an administrative hearing. A second opinion from another eye specialist can strengthen your case, especially if your condition has recently improved or stabilized after treatment.
