It’s no surprise, then, that yellow-tinted “night driving glasses” are so widely advertised, promising less glare and sharper vision after dark. But do night driving glasses work? Here’s what the evidence says, and what can make driving at night easier.

What Are Night Driving Glasses?

Night driving glasses usually have yellow- or amber-tinted lenses. They’re sold on the idea that the tint filters out some blue light, reduces the dazzle from headlights, and makes the road ahead look brighter and sharper.

They’re often sold online and in shops without a prescription, and some come as clip-on lenses that fit over your normal glasses.

Do Yellow Night Driving Glasses Work?

The short answer is no. Any tint, however light, reduces the amount of light reaching your eyes. In daylight, that can make things feel more comfortable. At night, when there’s already very little light, it makes dark parts of the road look even darker.

The yellow tint can make the view look brighter, but that’s an effect of the colour, not more light reaching your eyes. It doesn’t help you see more.

The research backs this up. In 2019 a study published in JAMA Ophthalmology, researchers at Harvard Medical School’s Schepens Eye Research Institute tested three makes of yellow-lens night driving glasses in a driving simulator. Drivers spotted pedestrians no sooner with yellow lenses than with clear ones, and the yellow lenses did nothing to reduce the effect of glare from oncoming headlights. The researchers also warned that the glasses could make drivers feel more confident in their night driving than they should.

The College of Optometrists, the professional body for optometrists in the UK, advises drivers to avoid yellow-tinted lenses for night driving, because they’re not proven to help and can make it harder to see dark areas of the road.

What Does the Highway Code Say?

Rule 94 of the Highway Code is clear: “At night or in poor visibility, do not use tinted glasses, lenses, or visors if they restrict your vision.”

Optometrists use a technical measure for this. The College of Optometrists recommends that lenses letting through less than 75% of light aren’t suitable for driving at twilight or at night. Sunglasses, including polarised lenses, fall well below that, so they should only ever be worn for driving in daylight.

Why Does Glare Feel Worse at Night?

When it’s dark, your pupils widen to let in as much light as possible. That helps you see in low light, but it also means bright lights, like headlights, scatter more inside the eye and dazzle you for longer.

Glare can also be a sign of an eye condition, especially if it’s new or getting worse:

• Cataracts: Clouding of the lens inside the eye scatters light, causing glare and haloes around headlights and streetlights.
• Astigmatism: An uncorrected or out-of-date prescription can make lights look streaky or smeared.
• Dry Eye: An uneven tear film on the surface of the eye can blur vision and make glare worse, particularly with the car heater blowing.

Age plays a part too. As we get older, our eyes let in less light and take longer to recover from glare. In the 2019 study, glare slowed older drivers’ reactions to pedestrians by 1.5 seconds, compared with 0.3 seconds for younger drivers.

What Actually Helps When Driving at Night?

Keep Your Prescription Up to Date

Even a small change in your prescription can make a noticeable difference after dark. If you need glasses to drive, you must wear them every time you drive. Yet the same College of Optometrists survey found that 24% of drivers who’d been told to wear glasses for driving admit that they don’t always do so. If it’s been more than two years since your last eye test, or you’ve noticed night driving getting harder, book an eye test.

Ask About an Anti-Reflection Coating

Rather than a tint, an anti-reflection coating on clear prescription lenses reduces the reflections bouncing around your lenses from headlights and streetlights, without darkening your view of the road.

Don’t Look Straight at Oncoming Headlights

If you’re dazzled, look towards the left edge of your lane rather than into the lights, and slow down if you need to until your vision recovers.

Keep a Spare Pair in the Car

If you only need glasses for driving, keeping a spare pair in the glove box means you’re never caught without them.

Night Driving Glasses FAQs

Are Night Driving Glasses Legal?

They’re legal to sell, but the Highway Code says not to use tinted glasses at night or in poor visibility if they restrict your vision. Because any tint reduces the light reaching your eyes, they’re best avoided after dark.

Can I Wear Polarised Sunglasses to Drive at Night?

No. Polarised sunglasses are excellent for cutting glare in bright daylight, but they let through far too little light for driving at dusk or in the dark.

Do I Need to Tell the DVLA if I Struggle to See at Night?

Not just because night driving feels harder. But you must meet the eyesight standard for driving, and you must tell the DVLA about certain eye conditions. Our guide to whether you need to tell the DVLA you wear glasses explains the rules.

When Should I See an Optometrist About Night Driving?

If glare is new, getting worse, or you’re seeing haloes or starbursts around lights, book an eye test. Your optometrist can check for cataracts, astigmatism, and dry eye, and make sure your prescription is right for driving.

See Clearly After Dark

Yellow night driving glasses might look like a quick fix, but the evidence shows they don’t help you see better at night, and they can make the darkest parts of the road harder to see. Clear, up-to-date prescription lenses with an anti-reflection coating, clean glasses, and a regular eye test do far more to keep you safe on the road this winter.

If night driving is getting harder, book an eye test at your nearest D.I. Blow Opticians branch.

Driving Eyesight Rules

According to the GOV UK website, you must wear glasses or contact lenses every time you drive if you need them to meet the ‘standards of vision for driving’.

You must tell the DVLA if you’ve got any problem with your eyesight that affects both of your eyes, or the remaining eye if you only have one eye.

This does not include being short-sighted or long-sighted or colour-blind. You also do not need to say if you’ve had surgery to correct short-sightedness and can meet the eyesight standards.

When you apply for a driving licence, you must state whether you wear glasses when driving; your licence is usually endorsed with code 01.

If You Need an Eye Test

If you report a medical condition that affects your vision, the DVLA may refer you for an eyesight test with their contracted optician. You do not have to pay for the test.

The DVLA then considers all medical evidence provided with a driving licence application, including the eyesight test result.

If you choose to get your eyesight test from somewhere else, you can submit the results done by another optician as long as it includes an ‘Esterman visual test’. The DVLA does not guarantee that they will accept an eyesight test conducted by other opticians. You will need to pay for the test yourself.

Eye Conditions and Driving

You must tell the DVLA if you have certain eye conditions. These conditions are:

• Blepharospasm
• Diabetic retinopathy (with laser treatment)
• Diplopia (double vision)
• Glaucoma
• Nyctalopia (night blindness)
• Retinitis pigmentosa

You must also tell the DVLA if any of the following apply:

• Your eye condition affects both eyes
• Your eye condition affects one eye, but you only have vision in that eye
• You have retinitis pigmentosa that affects one or both eyes
• A GP, optician, or eye specialist has said you should not drive
• You do not meet the visual standards for driving

Be aware that you can be fined up to £1,000 if you do not tell the DVLA about a medical condition that affects your driving.

If a Health Condition Affects Your Driving

You can voluntarily give up your licence. You might choose to do this if, for example:

• Your doctor tells you to stop driving for 3 months or more
• Your medical condition affects your ability to drive safely and lasts for 3 months or more
• You do not meet the required standards for driving because of your medical condition

You’ll need to tell the DVLA and send them your licence.

How Reporting Works

If you do need to inform the DVLA about a vision condition:

• Report Online or By Form: Most people can report a condition online through the GOV.UK service. In special cases, you may need to fill in a paper form (Form V1).
• DVLA Assessment: The DVLA may require further evidence or refer you for an eyesight test arranged by them, at no cost to you.
• Licence Decision: The DVLA will review medical evidence before deciding whether your licence remains valid, needs conditions, or needs to be revoked.

Standard of Vision for Driving

You must be able to read a car number plate made after 1 September 2001 from 20 metres away (about the length of 5 parked cars), wearing your glasses or contact lenses if you need them to drive.

You must also meet the minimum eyesight standard for driving by having a visual acuity of at least a decimal 0.5 (6/12) measured on the Snellen scale (with glasses or contact lenses, if necessary) using both eyes together or, if you have sight in one eye, in that eye.

You must also have an adequate field of vision; your optician can tell you about this and do a test.

Lorry & Bus Drivers

You must have a visual acuity of at least 0.8 (6/7.5) measured on the Snellen scale in your best eye and at least 0.1 (6/60) on the Snellen scale in the other eye.

You can reach this standard using glasses with a corrective power not more than +8 dioptres, or with contact lenses. There’s no specific limit for the corrective power of contact lenses.

You must have an uninterrupted horizontal visual field of at least 160 degrees with an extension of at least 70 degrees left and right, and 30 degrees up and down. No defects should be present within a radius of the central 30 degrees.

Can You Rely on the Number Plate Test?

No. The number plate check is only a quick roadside guide, and it doesn’t prove you meet the legal standard. The College of Optometrists’ position is that reading a number plate at 20 metres doesn’t correspond to the 6/12 acuity standard, and it tells you nothing about your field of vision, which you also need to meet. Only an eye test measures both. If you haven’t had one in the last two years, or you’ve noticed any changes in your sight, book one before your next drive.

Is 6/7.5 Vision Okay for Driving?

For a car or motorbike, the minimum is 6/12 using both eyes together, and 6/7.5 is sharper than that, so it meets the acuity part of the standard. The stricter 6/7.5 figure applies to lorry and bus drivers. Your field of vision has to meet the standard too.

Do Opticians Tell the DVLA?

Usually not. It’s your responsibility as the driver to tell the DVLA about a condition that affects your driving. If your optometrist finds that your sight doesn’t meet the standard, they’ll tell you, and they’ll advise you not to drive. If a patient keeps driving against that advice, professional guidance allows an optometrist to inform the DVLA as a last resort.

Are Eye Tests Changing for Drivers Over 70?

In January 2026, the government proposed compulsory eyesight tests for drivers aged 70 and over, every three years when they renew their licence. The consultation closed in May 2026. Until a decision is announced, drivers over 70 still declare their own eyesight when they renew.

In summary, you don’t have to tell the DVLA simply because you wear glasses. What matters is whether your vision meets the legal requirements for safe, consistent driving. However, if you have a condition that affects your sight significantly, or you cannot meet vision standards even with glasses, then you must notify the DVLA.
