DMV Vision Test in California: Requirements & What to Expect (2026)

1. The 20/40 Standard, Explained in Plain Words

Every guide about this test starts with “20/40,” and almost every guide stops there. That is the first trap in this topic, because 20/40 on its own is not the California rule — it is the shorthand for it. 20/40 means this: what a person with textbook-normal vision can read at 40 feet, you can read at 20 feet. It is a measure of distance sharpness, not a grade for your overall eye health, and it says nothing by itself about colour vision, depth perception, or side vision. The California rule, written in the state regulation that governs vision screening (Title 13, California Code of Regulations, section 20.03) and printed on the DMV’s own vision form, has three legs, and all three must be met:

The standard applies with or without corrective lenses. That sentence matters more than it looks: wearing glasses or contacts is not a workaround, and it is not held against you. It is simply how the test is taken, and the only consequence is the restriction discussed in section 4. The DMV’s public pages often shorten the whole rule to “the vision standard of 20/40,” which is why so many secondary pages repeat a one-leg version — “20/40 in at least one eye” or “20/40 in both eyes.” Both simplifications are wrong as statements of the rule, and the difference is not academic. It decides real cases:

Keep one more distinction in mind from the start, because the rest of this guide depends on it. The screening standard above is a gate, not a verdict. Failing it sends you to a specialist exam and possibly a driving test, where the real decision is made. The verdict — the point at which the DMV will not issue or renew at all — is a different, much lower line, covered in section 8: best-corrected vision of 20/200 or worse in the better eye. Between 20/70-in-the-weaker-eye and 20/200-in-the-better-eye lies a wide band of drivers who keep driving, with restrictions, after following the process. If you remember only one sentence from this guide, make it that one.

2. Who Must Take the Vision Test

The regulation states the scope in one sentence: individuals applying for or renewing a driver’s licence must submit to a screening of their eyesight and meet the department’s vision screening standard. The DMV’s own driving-independence page states it even more bluntly: all new and renewing driver licence applicants must pass a vision test, and applicants should bring their current glasses or contacts. In practice, that breaks down into four groups, and the differences between them explain most of the confusion about “do I have to take it?”

First-time applicants. The vision screening is part of the first licence process, at the same office visit as the knowledge test and the rest of the application. Our first-time licence guide covers that visit end to end; this page covers the vision step inside it. There is no separate appointment for the vision test and no separate fee for it — it rides inside the licence transaction.

Renewing drivers. Every in-person renewal includes the screening. This is the group most people asking about this test belong to, and it is where the renewal-only rules in this guide (the 60-day temporary licence, the DL 62 reuse rule) apply. If you renew online or by mail and your renewal is eligible for that channel, there is no in-office chart test at that renewal — but be careful with that sentence. The regulation still requires a renewal applicant to submit to screening, and it expressly allows the requirement to be met by providing a DL 62 or a specialist’s letter, in person or remotely through the DMV website. “Online renewal” is therefore not the same as “no vision check ever”; it is “no chart test at the counter this time.”

Drivers aged 70 and older. There is no separate senior vision test, and no easier or harder version of the chart for seniors — a myth worth killing outright, because several competitor pages imply a special senior test exists. What is real is the channel: at 70, renewal is in person every five years, so the screening happens at every one of those renewals, without exception. The application can be started online, and where a knowledge component is required the no-fail eLearning course can be taken at home, but the renewal is finished at an office, including the vision test and a new photo. One timing tip from the DMV’s own 70+ roadmap belongs here: allow one business day for your payment to show on your record before visiting for the vision test, or the visit may be wasted.

Drivers ordered into a reexamination. A vision test is one component a reexamination can include, alongside a knowledge test and a behind-the-wheel evaluation. Section 10 covers who can trigger a reexamination and what happens next. Age alone never triggers one: California law states that the age of a licensee, by itself, may not constitute evidence of a condition requiring an examination of driving ability, and the DMV repeats the point on its senior pages — it evaluates all drivers using the same standards.

Commercial drivers are the one group this page deliberately does not cover. Commercial licences operate under separate federal medical standards, and the 20/40 Class C screening described here is not the CDL rule. If you hold or are applying for a commercial licence, do not use this page’s numbers for that transaction.

3. At the Office, Step by Step: What Actually Happens

The test is short, and most of the anxiety around it comes from not knowing the sequence. Here it is, exactly as the DMV describes it on its senior drivers page, which is the fullest public description the DMV publishes.

Two things the office test is not, because competitor pages routinely claim otherwise. First, no DMV page read for this guide describes a colour-vision or depth-perception test as part of the office screening; the verified instruments are the wall chart and the Optec 1000. If a guide tells you the DMV tests your colour vision at the counter, it is describing something it has not sourced. Second, this guide states no “how many letters you may miss” allowance for the 20/40 line, because no DMV page publishes one — and any page that quotes one is inventing it. What the DMV does publish is the full second path, which is where a borderline result actually gets decided.

4. Glasses and Contacts: Passing With Them, and What Follows

Wear them. That is the whole advice, and it is the DMV’s advice too: bring your current glasses or contacts, take the test wearing them, and accept the consequence, which is a restriction, not a penalty. If you pass the vision test while wearing glasses or corrective contact lenses, your licence carries a corrective-lens restriction: you must wear corrective lenses while driving. If you pass without glasses or contacts, there is no lens restriction. The restriction follows the test result, not your prescription alone — it is the DMV’s record of how you passed, and driving without the lenses you passed with means driving outside your licence restriction.

The reverse move is real, though it is often described more casually than it should be. If you later have corrective surgery and no longer need lenses, the mechanism for removing the restriction is to return and pass the screening without lenses; the removal follows a passed screening. This guide does not promise automatic removal or a particular form for it, because no DMV page read for this guide publishes a removal procedure beyond that retest logic — but the logic itself is the verified mechanism, and it is worth knowing before you assume a restriction is permanent.

One more practical point, from the DMV’s senior health advice rather than from any rule: get regular eye exams at least every two years, more often if your vision changes rapidly. That is advice, not a requirement, and it is labelled as such here. It is also the cheapest way to avoid the entire DL 62 path: most failed screenings this guide’s sources describe trace back to a stale prescription, not to an eye disease.

5. If You Do Not Meet the Standard: Form DL 62, Section by Section

Form DL 62 is the Report of Vision Examination. It is the DMV’s official vision-evaluation form, and understanding its two sections explains why the specialist visit is not just “go see an eye doctor and come back.” The form is doing two different jobs depending on your result, and the specialist fills in a different amount of it in each case.

The split that matters: if you meet the screening standard, the specialist completes only the Visual Acuity part and the Signature part of Section 2. If you do not meet it, all of Section 2 must be completed. That is why a DL 62 for a driver who missed the standard is a full clinical workup, not a signature on a form — and why it takes a real appointment, not a walk-in stamp. A substitute letter from the specialist is also accepted, but only if it contains everything the regulation requires: the specialist’s address and phone, your full name and birth date, the exam date, your acuity measurement, and the specialist’s signature and California licence number. A note that says only “vision OK” does not meet that list.

Three dating and handling rules decide whether your DL 62 is accepted at all, and all three are easy to get wrong:

• The exam must be within 6 months of your licence application date. An older exam does not count, however good the result was. If you submitted a DL 62 within the previous six months, a new one is not required — except if you had eye surgery within those six months, in which case you must complete and submit a new DL 62 so the specialist can update the DMV on your vision.
• Bring it back; do not mail it unless asked. The form’s own instructions say to bring the completed form and any new corrective lenses when you return to the DMV, and not to mail it back unless a DMV employee asks you to. Mailing it into a void is one of the small, common ways this process stalls.
• Do not rush back in unfamiliar new glasses. The DMV warns this in its own words: if your specialist prescribes new eyeglasses or recommends another correction, wait until you have completed the specialist’s recommendations before returning, because the DMV will retest your vision and you may not pass if you are not used to your new lenses. A driver who fails on Monday, gets new glasses on Tuesday, and retests on Wednesday in lenses their eyes have not adjusted to has manufactured a second failure out of impatience.

A final scope note for this section: only an ophthalmologist or optometrist may sign the DL 62. “Vision specialist” is a broad phrase in everyday speech, and the DMV’s own regulatory materials stress the narrower signer list. When this guide says “specialist,” it means one of those two licensed professions, every time.

6. The 60-Day Temporary Licence, the Retest, and the Driving Test

Return to the DMV with your completed DL 62 and you are retested. There are two branches, and the DMV states both in full on its senior page, so there is no need to paraphrase them loosely.

Branch one: you pass the retest. The DMV renews or issues your licence and adds (or retains) a corrective-lens restriction if you passed wearing glasses or contacts. No restriction if you passed without them. For most drivers on this path, the story ends here — a delay and an eye appointment, not a lost licence.

The paper temporary licence that bridges a renewal — the same 60-day document issued after a driving test — is covered in full in our paper temporary licence guide: its validity, what it allows, and what to do if the card never arrives.

Branch two: you still do not meet the standard. The DMV schedules a Supplemental Driving Performance Evaluation (SDPE) — a behind-the-wheel driving test — to see whether you can compensate for the vision condition in real traffic, wearing the glasses or contacts your specialist prescribed. Pass the SDPE and the licence is renewed with (or retaining) the corrective-lens restriction. The SDPE is the point where the process stops being about chart lines and starts being about demonstrated safe driving: scanning, mirror use, judgement at intersections, and the compensations a driver with reduced vision actually uses. In some situations — where you live in an area where the driving environment is less demanding than the area around your local DMV office — you may have the option of an Area Driving Performance Evaluation (ADPE) instead: an examiner comes to your home area and tests you there, and passing restricts your licence to that geographical area and the specific roads and routes you were tested on, possibly plus no-freeway and/or daylight-only restrictions.

If the SDPE does not go your way, or if the specialist’s findings point to a condition that cannot be compensated for, the outcomes narrow to the restriction, limited-term, suspension, or revocation range described in section 8, with the hearing rights in section 10. That is the honest endpoint of the chain, and it is why the earlier steps matter so much: every driver who fixes a prescription, waits until they are used to new lenses, and returns with a complete, in-date DL 62 has already removed the three most common reasons for reaching that endpoint unnecessarily.

7. One Eye, Monovision, Bioptic Lenses, and the 20/200 Floor

These four cases are searched as if they were four separate rules. They are not: they are four applications of the same two thresholds — the screening standard and the hard floor — and keeping them separate in your mind is what stops a frightening search result from becoming a wrong conclusion.

Driving with vision in only one eye. There is no separate one-eye ban in the rules cited in this guide. What matters is the better eye. If the functioning eye reaches 20/40 (with or without correction) and the better-eye acuity is better than 20/200, the acuity legs of the screening can be met; the driver should still expect the DL 62 path, a possible SDPE, and restrictions, because a one-eye history is exactly the kind of case the specialist exam and the driving test exist to judge. If the better eye is 20/200 or worse even with correction, the floor below bars issuance or renewal outright. This guide does not promise any individual one-eyed driver a licence — it lays out the test that driver will actually face, which is the honest version of the answer.

Monovision. Monovision means one eye corrected for distance vision and the other for close-up vision, whether by contact lenses or by refractive surgery. If the DMV has no record of your monovision, the path is DL 62, specialist, and SDPE on return, to determine whether you can drive safely. But there is an exemption worth knowing: under the regulation, a person with a long-standing, static vision condition — monovision is named expressly — is not required to obtain a DL 62 for subsequent renewals, provided they meet the screening standard in the better eye and the DMV already has the relevant documentation on record (or it is submitted with the application). First time through, expect the full path; on later renewals with the condition documented and the better eye passing, expect it to be simpler.

Bioptic telescopic lenses. If your specialist has prescribed a bioptic telescopic lens, you may not wear it to pass the vision test. That sentence is routinely flattened online into “you cannot drive with bioptic lenses,” which is the opposite of the actual rule. The actual rule: you take a DL 62, see your specialist, and on return you take an SDPE wearing the bioptic lens, to determine whether you can drive safely with it. Pass, and your licence is restricted to wearing the bioptic lens when driving — plus a daylight-only restriction if you passed the driving test during the day, and no daylight restriction if you passed it at night. The lens is not a way to pass the chart; it is a way to pass the driving test.

The 20/200 floor. The DMV will not issue or renew a licence to a person whose best-corrected visual acuity is 20/200 or worse in the better eye, as verified by an optometrist or ophthalmologist. A bioptic telescopic or similar lens may not be used to meet this floor. Note the three qualifiers, because each one is doing work: best-corrected (with your best lenses, not without them), better eye (the stronger eye decides), and verified by a specialist (the office chart does not set this floor — the DL 62 exam does). A driver at 20/200 in the better eye even with correction is not on the DL 62-and-SDPE path; that driver is past the point where the regulation permits a licence. Everyone better than that line is, by contrast, inside a process with options — which is why the screening standard and the floor must never be quoted as if they were the same number.

8. Licence Restrictions That Can Follow a Vision Evaluation

Restrictions are the DMV’s middle ground between a full licence and no licence, and they are far more common than refusals. They may be discretionary (imposed by the DMV on the examiner’s findings and your circumstances) or mandatory (required by law), under Vehicle Code sections 12812, 12813, and 13800. The vision-relevant subset, from the DMV’s own published lists and the vision sections of its pages, is:

This is the vision-relevant subset, not a complete catalogue of California licence restrictions, and it should not be quoted as one. Driving outside a restriction on your licence — for example, driving at night on a daylight-only licence, or without the lenses your licence requires — means driving outside the terms of the licence itself, which is a different and more serious matter than merely having poor vision. If a restriction no longer fits your vision, the route back is the same mechanism as the route in: a new screening or specialist exam that supports changing it.

9. Seniors: No Separate Test, but a Test at Every Renewal

Repeat the correction, because it is the most searched senior myth in this topic: there is no separate senior vision test. The chart is the same, the machine is the same, and the standard is the same. What changes at 70 is the renewal channel, and the channel is what guarantees the test: in-person renewal every five years, vision screening at each one, new photo at each one. The DMV evaluates all drivers using the same standards, including senior drivers, and says so in terms.

What does change with age, and what the DMV’s senior pages describe at length, is the background against which the test happens: eyes need more light, glare from sun and oncoming headlights bothers more, night vision and contrast fade, side vision narrows, and conditions such as cataracts, macular degeneration, and diabetic retinopathy become more common. The DMV’s own advice for drivers noticing these changes is practical rather than medical, and it is worth repeating with attribution because it comes from the DMV, not from this guide: get regular eye exams at least every two years (more often if vision changes rapidly); limit yourself to daytime driving if night vision or glare recovery is a problem; turn your head frequently to compensate for reduced side vision; consider a larger rearview mirror; look at least one block ahead in the city and 12 to 15 seconds ahead on the highway; and avoid wide-frame glasses whose temples block side vision. None of that is a rule, and none of it substitutes for the screening — but all of it is how drivers stay on the passing side of the screening for longer.

For the full senior renewal process — the application, eLearning where a knowledge component is required, REAL ID at renewal, and the payment-timing tip — see our seniors guides, linked below. This page deliberately keeps the senior-renewal summary to the vision slice, so the two guides do not drift out of sync with each other.

10. Reported or Referred? The Reexamination Path

A large share of vision-test searchers are not applicants at all. They are adult children, spouses, or drivers who have just received a reexamination notice, and their question is different: “who started this, and what happens now?” The verified chain is short and worth stating whole.

A reexamination can be requested by your doctor (physicians are required by law to report conditions involving loss of consciousness or control, and other conditions that may affect safe driving), by emergency personnel who treated you, by a family member, friend, or neighbour, by a peace officer who observed your driving, by your own renewal application (answering “Yes” to a disease, disorder, or disability question), or by your driving record itself. Anyone may also report a possibly unsafe driver with a Request for Driver Reexamination (form DS 699) or a signed letter to the local Driver Safety office; reporters may request confidentiality, and reports related to medical conditions are confidential under Vehicle Code section 1808.5. The Driver Safety Branch phone published on the DMV’s driving-independence page is (833) 543-7703.

The urgent variant is the priority reexamination: if a peace officer observes unsafe driving and issues a priority reexamination notice, you must contact the local Driver Safety office within five days or your licence will be suspended. That five-day clock is the deadline that matters most in this section, and it is not a vision-specific deadline — it is the priority-notice deadline, whatever triggered the notice.

A reexamination itself can include a vision test, a knowledge test, and a driving evaluation, plus requests for medical information and, where needed, a hearing. If the DMV then acts against your privilege, you may request a DMV administrative hearing: within 10 days if the notice was personally given to you, or 14 days if it was mailed. At the hearing, the officer may dismiss the action, restrict the licence or place you on probation, or uphold the suspension or revocation. Present those clocks as the notice-of-action hearing window, not as a separate “vision appeal deadline” — no such separate deadline was verified. Our medical-suspension and reexamination guides cover hearing procedure in full; this section is the map, not the territory.

11. Mistakes That Cost People a Second Trip

Almost every failed or stalled vision transaction in the sources for this guide traces back to one of six avoidable errors. They are worth a section of their own because each one is cheap to prevent and expensive to repeat.

• Leaving your glasses or contacts at home. The test is taken with the correction you drive with. Without it, a driver who would have passed fails the chart and starts the DL 62 clock for nothing.
• Testing with a stale prescription. If your last eye exam was years ago and your vision has changed, the chart will tell you before your eye doctor does. An exam before the DMV visit, when you know your vision has changed, is the simplest prevention in this guide.
• Rushing back in brand-new lenses. The DMV’s own warning, repeated here because it is so often ignored: wait until you are used to new glasses before returning for a retest, or you may fail a test you would have passed a week later.
• Bringing an out-of-date DL 62. The exam must be within six months of the application. An older form, however favourable, does not count — and eye surgery inside the last six months means a new form is required even if you already submitted one.
• Mailing the DL 62 instead of bringing it. Bring the completed form and any new lenses to the office. Mail it only if a DMV employee asks you to.
• Driving on an expired licence while waiting. The 60-day temporary licence is for renewals at the 20/70-both-eyes threshold. It is not a general permission to keep driving while a vision case is open, and no page should present it as one. If your licence is close to expiry and the process is still open, the safe move is to complete the steps, not to assume the bridge covers you.

12. Four Myths, Corrected

Myth 1: “Failing the eye test means losing your licence.” No. Failing the screening starts the DL 62 path. Losing the licence is the endpoint of a chain — failed retest, failed SDPE, or a condition past the 20/200 floor — and most drivers on the chain never reach it.

Myth 2: “Seniors take a different, harder eye test.” No. Same chart, same machine, same standard. What seniors get is a guaranteed test at every five-year in-person renewal, because their channel is always in person.

Myth 3: “Bioptic lenses are banned for driving.” No. They cannot be worn to pass the chart. They can be worn to pass the SDPE, and then the licence is restricted to wearing them — with a daylight-only restriction added if that driving test was passed during the day.

Myth 4: “One bad eye means no licence.” No. The better eye decides the floor, and the full standard decides the screening. A driver with one weak eye and one strong eye may pass outright (if the weak eye is at least 20/70), may go through DL 62 and SDPE, or may be restricted — but the weak eye alone is not a refusal.

One last honesty note, because this guide has been careful with numbers throughout: this page states no visual-field degree figure, no colour-vision or depth-perception office test, no DL 62 processing time, no immediate-retake promise, and no commercial-licence vision numbers. Each of those figures circulates online; none of them was verified on a DMV page read for this guide, and a guide that invents precision where the official source is silent is less trustworthy, not more. Where the DMV is silent, this page says so and points you to the process that decides your case instead.
