You can keep driving with cataracts as long as your vision, corrected with glasses or contacts if you use them, still meets your state’s licensing standard. A diagnosis by itself changes nothing on your license. What matters is the measured acuity in your better eye and, in some states, your field of vision. Cataracts are progressive, though, so the question is really about when that will stop being true and what to do before it does.
The Vision Threshold You Have to Meet
Every state sets a minimum visual acuity for a standard driver’s license, and 47 of them draw the line at 20/40 in the better eye with or without corrective lenses. Georgia allows 20/60. New Jersey and Wyoming allow 20/50.1American Medical Association. Legal Vision Requirements for Drivers in the United States Twenty-forty means you can read at 20 feet what a person with normal vision reads at 40 feet. If glasses get you there, your license will carry a corrective-lens restriction, and driving without those glasses is a traffic violation.
Most states also require a minimum horizontal field of vision. Of the 34 states that publish a specific number, 15 require 140 degrees, and the rest fall between 105 and 150 degrees.1American Medical Association. Legal Vision Requirements for Drivers in the United States Peripheral vision is what lets you catch a car merging from the side or a cyclist coming into an intersection. Some states also check that you can distinguish red, green, and amber signals.
Signs Your Cataracts Are Affecting Your Driving
The eye chart at the DMV does not capture everything a cataract does to your vision. The National Highway Traffic Safety Administration lists several signs the condition is starting to interfere with driving: trouble seeing at dawn, dusk, or night; sunlight that feels painfully bright; halos or starbursts around oncoming headlights; colors that look washed out; double images in one eye; and frequent changes in your glasses prescription.2NHTSA. DriveWell: Driving When You Have Cataracts
Reduced contrast sensitivity is one of the more dangerous effects because standard acuity tests do not measure it. You can pass a 20/40 screening and still struggle to see a gray car against a gray road on an overcast day, or miss a pedestrian in dark clothes at twilight. Night driving is usually where the trouble shows up first. If you have started avoiding unfamiliar roads after dark, or gripping the wheel harder against headlight glare, that is your vision telling you something the DMV chart will not.
Who Reports Your Condition, and Who Doesn’t
Most states require you to self-report a medical change that affects your ability to drive safely, and failing to do so can be grounds for suspension.3NHTSA. Driver Fitness Medical Guidelines Enforcement, in practice, runs on the honor system. The licensing agency does not know your cataracts have worsened unless you tell them, your doctor tells them, or you fail a vision screening at renewal.
On the physician side, only six states require doctors to report medically impaired drivers to the licensing authority: California, Delaware, Nevada, New Jersey, Oregon, and Pennsylvania. Of those, only Oregon and Pennsylvania specifically mandate reporting vision impairment.4National Library of Medicine. Reporting Requirements, Confidentiality, and Legal Immunity Everywhere else, the call is yours.
Restrictions Instead of Losing Your License
When your vision has slipped but not fallen below the legal floor, your state will often add restrictions rather than pull your license. The most common is a corrective-lens requirement. Others you may see:
- Daylight driving only, when night vision is significantly impaired. This is a common outcome with cataracts.
- Speed restrictions that keep you off highways.
- Area restrictions confining you to a set radius from home or within your county.
- A requirement for additional outside mirrors to compensate for reduced peripheral vision.
Violating a restriction printed on your license is a traffic offense, and in many jurisdictions it is treated the same as driving without a valid license. Restrictions are a middle ground worth taking seriously, because they can keep you driving for the parts of your life that need it while the condition is still manageable.
Renewal Can Be the Real Turning Point
Cataracts develop overwhelmingly in people over 60, which puts them on a collision course with age-based renewal rules. About half the states shorten the renewal cycle for older drivers, require in-person renewal instead of online or mail, or require a vision test at renewal once you reach a certain age.5Insurance Institute for Highway Safety. Older Drivers: License Renewal Procedures Triggers vary. Some kick in at 60 or 65, others at 75 or 85. At least 19 states require a vision test at every renewal after a specified age, ranging from 40 in Maryland to 79 in Texas.
A cataract you have been managing quietly for years can turn into a licensing problem the day your renewal comes due. If yours are worsening, check your state’s renewal requirements well before your license expires. Getting turned away at the counter is a bad way to find out you needed surgery three months ago.
A Note for Commercial Drivers
If you hold a commercial driver’s license, the standard is stricter and federally uniform. Under 49 CFR 391.41, you need at least 20/40 in each eye individually, 20/40 binocular acuity, a field of vision of at least 70 degrees in each eye, and the ability to recognize red, green, and amber signals.6eCFR. 49 CFR 391.41 – Physical Qualifications for Drivers The per-eye rule is the key difference from a standard license, where only your better eye has to clear the bar.
Drivers whose worse eye falls short may still qualify under the alternative vision standard the Federal Motor Carrier Safety Administration established in March 2022, which replaced the older Federal Vision Exemption Program.7Federal Motor Carrier Safety Administration. General Vision Exemption Package A certified medical examiner decides whether a stable visual deficiency is compatible with safe operation, and the resulting certificate is valid for up to a year. For CDL holders, the timeline to address cataracts is tighter, because losing acuity in either eye alone can disqualify you.
Driving After Cataract Surgery
Cataract surgery is one of the most common and successful procedures performed in the United States. In one longitudinal study, only about 1 percent of drivers had acuity worse than 20/40 in their better eye after surgery.8National Library of Medicine. Visual Function and Car Driving: Longitudinal Results 5 Years After Cataract Surgery For most patients, surgery restores enough vision to meet the legal standard comfortably.
You cannot drive on the day of surgery, and you will need a ride home. Daytime driving clearance usually comes within a few days to a week, at the first post-operative visit when your ophthalmologist checks your acuity. Night driving takes longer, since your eyes need time to adjust to low light and halos around lights are common in the early weeks. Two to four weeks is a reasonable expectation before night driving feels normal again.
If you need surgery on both eyes, the procedures are typically scheduled about two weeks apart. During that gap, depth perception can feel off, because one eye has a new artificial lens while the other still has the cataract. Your doctor may suggest removing the lens from your old glasses on the operated side, wearing a contact in the non-operated eye, or going without correction for the interval.9American Academy of Ophthalmology. Cataract Surgery Recovery: Exercising, Driving and Other Activities Not driving at all during those two weeks is the simplest option if your schedule allows it.
Once both eyes have healed and your ophthalmologist confirms your acuity meets the state standard, you can ask the licensing authority to remove any vision-related restriction on your license. That usually means submitting a completed vision examination form from your eye doctor. If new intraocular lenses bring your uncorrected vision to 20/40 or better, the old corrective-lens restriction may come off entirely.
What Happens If You Keep Driving Anyway
Driving when you know your vision does not meet the legal standard is not a gray area. A traffic stop or an accident can bring citations, fines, and suspension or revocation. The larger risk comes if impaired vision contributes to a crash. A driver who knew about a vision problem and kept driving has a hard time arguing they exercised reasonable care, which is the core of a negligence claim. Damages in a civil suit can include medical bills, lost income, property damage, and pain and suffering. On bad enough facts, the same conduct can support a reckless driving charge, which carries criminal penalties including possible jail time in most states.
Insurance adds another layer. Your liability policy will generally still cover the other driver’s damages, because that is what liability insurance does. But if your insurer finds out you were driving in violation of a license restriction or with a condition you did not disclose, expect a sharp premium increase at renewal or a non-renewal notice. The financial cost of a serious crash tied to preventable vision loss reaches well past the crash itself.
