Night Driving Glasses: Do They Work, and Are They Safe?
By Laura Pemberton · Updated on 7 October 2026
Short answer: night driving glasses with yellow or amber lenses are not proven to improve what you can see at night, and the College of Optometrists advises against yellow filters because a tint can make dark parts of the road look darker. Some drivers find a light amber lens makes oncoming headlights feel less harsh, but no lens removes glare. If headlights are bothering you, start with an eye test and a clean windscreen. If you then want to try night driving glasses, choose a light tint, and stop wearing them if they restrict your vision in any way.
We sell night driving glasses, HaloBlock™, so we have an interest here. That is exactly why this guide sets out what UK rules and eye experts say first.
Why does headlight glare feel worse than it used to?
It is not just you. The RAC's research from February 2026 found that a quarter of drivers affected by headlight glare are either driving less at night or have given up altogether. A TRL study cited by the RAC notes that many modern headlights are brighter and whiter than the old halogen bulbs, and taller vehicles such as SUVs put their lights closer to the eye level of drivers in lower cars. One Mumsnet member described it simply: "my car seat is quite low so all those SUVs bright lights are right at my eye level".
What do UK rules and eye experts say about night driving glasses?
| Source | What it says |
|---|---|
| The Highway Code, rule 94 | "At night or in poor visibility, do not use tinted glasses, lenses or visors if they restrict your vision." |
| The Highway Code, rule 115 | Drivers should "slow down, and if necessary stop, if you are dazzled by oncoming headlights." |
| College of Optometrists (public advice) | "Avoid lenses with yellow-coloured filters, as these are not proven to help and may even be dangerous, as the tint makes dark parts of the road appear even darker." |
| College of Optometrists (clinical guidance) | "Sunglass filters with a luminous transmittance of less than 75% are not suitable for road use in twilight or at night." |
| Which? | Reports a 2019 study in which yellow-lens night driving glasses neither reduced glare nor helped drivers see pedestrians more easily. |
So the honest position is this: the Highway Code doesn't ban tinted lenses at night outright, but it makes you responsible for making sure they don't restrict your vision, and the eye experts are sceptical that yellow lenses help.
What should you do first about headlight glare?
- Book an eye test. An optometrist can check whether your prescription has changed, or whether something else, such as a cataract, is making glare worse. If you need glasses to drive, the Highway Code says you must wear them.
- Ask about an anti-reflection coating. The College of Optometrists recommends it on your prescription glasses for night driving.
- Clean your windscreen inside and out. A film of grime or condensation scatters light and makes glare worse. Our guide on removing smudges, streaks and fog from car glass shows how.
- Keep your own glasses clean. The same applies to any lens you look through.
- Slow down when you are dazzled. And if you need to, stop, as rule 115 says.
If you do try night driving glasses, what should you look for?
- A light tint, not a dark one. Sunglasses are for daytime. The College's guidance is that filters letting through less than 75% of light are not suitable at night, so ask for the transmission figure of any lens you are considering.
- A fit over your own glasses. If you wear prescription glasses, the night lenses must go over them, not replace them.
- Side protection. Light from the side and from your mirrors adds to glare.
- An easy way to stop. If the road looks darker, if you struggle to see pedestrians or unlit lanes, take them off.
Our HaloBlock™ anti-glare night driving glasses have light amber, polarised lenses with high light transmission (we don't quote a percentage), side lenses and an anti-fog coating. They sit over most standard prescription glasses or can be worn on their own, and come with a hard-shell case and a microfibre cloth. They soften the harsh white of LED headlights for some drivers; they won't make headlights disappear, they don't correct your sight and they don't replace your prescription glasses.
Who are night driving glasses not for?
- Drivers with astigmatism or cataracts looking for a cure. As a Mumsnet member put it: "They help a bit, but they don't get rid of the astigmatism halo." A Gransnet member was blunter: "Anti glare glasses make no difference if the problem is a cataract." See your optometrist.
- Driving on dark, unlit roads. One driver on Mumsnet said they would not use them "on lanes with no streetlights and not much traffic as they do make things seem dark."
- Anyone who finds they see less with them on. That is your answer: don't wear them.
FAQ
Are night driving glasses legal in the UK?
There is no specific ban, but rule 94 of the Highway Code says not to use tinted glasses, lenses or visors at night or in poor visibility if they restrict your vision. You are responsible for making sure they don't.
Do yellow lenses help you see better at night?
The evidence says no. The College of Optometrists says they are not proven to help, and a 2019 study reported by Which? found no improvement in glare or in seeing pedestrians.
Can I wear them over my glasses?
HaloBlock™ fits over most standard prescription glasses. Very large or chunky frames may be a tight fit. More detail is in the FAQ on the HaloBlock™ page.
What if they don't suit me?
You have 90 days to return them, and they are covered by our Lifetime Warranty with free replacement.
