Keeping your vision roadworthy is your responsibility and is essential for your safety and everyone else’s. In this guide we'll cover what the rules and legal eyesight standards are in the UK.
What are the legal eyesight standards for driving?
In the UK, you need to read a number plate from 20 metres away. That’s about five car lengths. If you wear glasses or contacts, make sure you’re using them while driving.
How much you can see around you without moving your head is also important. This is often referred to as your field vision. Legally, you need a minimum horizontal field of 120 degrees to pick up movement and hazards to your sides. For example, being able to spot cyclists, pedestrians, or cars.
You can stay up to date on the latest driving eyesight rules by following government guidance.
Lorry and bus drivers eyesight rules
Lorry and bus drivers have tougher rules, and for good reason. The size and weight of these vehicles mean sharper vision is needed to operate them safely.
You’ll need to achieve at least 6/7.5 on the Snellen scale. Regular medical check-ups are also required, including vision tests to ensure you're meeting the stricter standards.
Can an optician do the tests I need for driving?
Absolutely! Opticians are equipped to check your eyesight for driving. This includes reading a number plate from 20 metres and assessing your field of vision.
These tests are usually part of a standard eye check-up. They’ll also let you know if your glasses or contacts need updating.
Do I need to tell the DVLA if I need glasses or have poor eyesight?
If you wear glasses or contacts to meet the legal standard, there’s no need to tell the DVLA.
However, if you’re diagnosed with an eye condition or if your eyesight worsens a lot you'll need to inform them. It’s relatively quick and easy to do online via the DVLA reporting service.
Failing to report changes could result in fines or worse an accident, especially if your condition affects your driving.
Medical causes for poor eyesight
Certain medical conditions can impact your vision and your ability to drive. These include cataracts, glaucoma, macular degeneration, and diabetic retinopathy.
Each of these conditions can reduce clarity, create blind spots, or affect your peripheral vision.
Regular check-ups and timely treatment can often manage symptoms effectively. Just remember to let the DVLA know if your condition affects your ability to drive safely.
Are my eyes tested on a driving test?
Yes, they are. Your driving test begins with a quick vision check. The examiner will ask you to read a number plate from 20 metres away.
Fail this, and your test won’t continue – so it’s worth making sure your eyesight is up to scratch before booking.
After your driving test it's worth keeping on top of regular optician appointments in case there are any changes with your eyesight.
Drivers over 60 and 70
Eyesight naturally changes as we age, often without us noticing. Drivers over 60 are advised to have their eyes tested every two years, and over 70s must renew their licence every three years.
During renewal, you’ll need to confirm that your vision still meets the legal standard.
It’s a good idea to schedule regular eye tests as you get older – it’s not just about staying legal; it’s about staying safe.
What's the punishment for not following the eyesight laws?
There are consequences if you’re caught driving with poor eyesight that's unchecked and that has not been reported to the DVLA.
You could face a £1,000 fine, three penalty points, or even lose your licence.
Worse still, if your poor vision causes an accident, you could face more serious consequences, including being held liable.
Regular eye tests could save you from a world of trouble – and from putting others at risk.
Does needing glasses affect my car insurance price?
No, wearing glasses or contacts won’t impact your car insurance quotes.
However, if you’re involved in an accident and it turns out your eyesight didn’t meet the legal standard, your insurer might refuse to pay out. Keeping your prescription up to date is a simple way to avoid this.
Are there any rules for people with colour blindness?
Yes, if you’re colour blind, you can still drive, but you’ll need to rely on recognising traffic lights and signs based on their position and shape rather than their colour.
It’s a good idea to familiarise yourself with the system before getting behind the wheel.
Tips to stay safe on the road if you wear glasses or contacts
- Always carry a spare pair of glasses in your car – you never know when you might need them.
- Make sure your prescription is up to date. Don’t wait until things get blurry to book an eye test.
- Consider anti-glare lenses or prescription sunglasses for driving in bright or low-light conditions.
- Keep your glasses or contacts clean. Dust and smudges can reduce visibility and increase glare.
Keeping your eyesight in check is part of being a safe and responsible driver. Got questions? Speak to an optician if you have any concerns about your eyesight.
