The Definitive Guide to UK Driving Eyesight Rules for Over 70s (2025 Update)
The brown envelope from the DVLA arrives right on time. It’s your D46P licence renewal form, and you’re staring at the ‘eyesight declaration’ section. For millions of UK drivers turning 70, this now causes serious confusion and anxiety.
For years, this was a simple ‘self-declaration’. You ticked a box to say your vision was fine. But new 2025 rules have officially changed the process. The old “honour system” is being replaced with a requirement for medical or visual evidence.
This guide cuts through the confusion. We will provide a clear, step-by-step plan covering the new 2025 requirements, the exact legal standards, how to renew with confidence, and what really happens when you declare a common eye condition.
Key Takeaways: Your 30-Second Briefing
- 3-Year Renewal: You must renew your driving licence when you turn 70, and every three years after that.
- The 3 Standards: You must meet all three legal standards: the 20-metre number plate test, the 6/12 visual acuity standard, and the minimum visual field standard.
- NEW 2025 RULE: You must now provide a medical or DVLA-approved eye test certificate (dated within two years) to validate your renewal. Pure self-declaration is no longer sufficient.
The 2025 Rule Change: What Over-70s Drivers MUST Know
This is the most significant change to driver licensing for seniors in years. The driving eyesight rules for over 70s in the UK are now stricter and based on evidence, not just trust.
The End of “Honour System” Self-Declaration
Previously, when renewing your licence, you simply self-certified that your eyesight met the legal standard. The DVLA reserved the right to make checks, but the primary responsibility was on you to “tick the box.”
Following a long-term government review and new road safety strategies, this system is being phased out. The House of Commons Library briefing on driver licensing (Source 1.1) highlighted calls for change for years, and as of late 2025, new rules are in effect.
The New Requirement: Medical & Eye Test Certificates Explained
When you now renew your licence at age 70 (and at 73, 76, etc.), you must be able to provide evidence that you meet the standards.
This means you will need a valid, DVLA-approved eye test certificate or a medical report (if you have other notifiable conditions) to support your application. This certificate must typically be dated within the last two years.
Why Have the Rules Changed?
The change is based on two key factors. First, official road safety statistics show that failing eyesight is a significant factor in road accidents involving older drivers. Second, high-profile campaigns, such as the one leading to “Cassie’s Law,” highlighted the dangers of the old system, where drivers who had been told they were unfit could continue driving simply by failing to notify the DVLA.
These new rules are designed to catch vision problems early, protect all road users, and ultimately help older drivers stay on the road safely for longer.
Common Pitfall: “My Optician Will Tell the DVLA for Me”
This is a critical misunderstanding. Your optician’s primary duty of care is to you. They will tell you if your vision is below the legal standard.
However, they can only breach patient confidentiality and report you directly to the DVLA without your consent if they believe you are a high risk to the public and will continue to drive against their medical advice. The legal responsibility to inform the DVLA (Source 1.2) is yours.
The 3 Legal Eyesight Standards You Must Meet
To be legal to drive in the UK, you must meet three distinct standards. Failing even one of them means you do not meet the legal requirement.
Standard 1: The 20-Metre Number Plate Test
This is the most famous test and the one a police officer can ask you to perform at the roadside.
The rule is simple: you must be able to read (with glasses or contact lenses, if you wear them) a new-style number plate from 20 metres.
Expert Tip: How to Test Yourself Correctly
Don’t just guess. 20 metres (or 65 feet) is roughly the length of five average-sized parked cars.
Find a parked car and pace it out. Can you read the plate clearly, first time, without excessive squinting or hesitation? If you struggle, or aren’t 100% sure, it’s a clear sign to book a full eye test with an optician before you send in your renewal form.
Standard 2: Minimum Visual Acuity (The 6/12 Snellen Scale)
This is the clinical standard measured at your optician’s. The legal minimum visual acuity for driving is 6/12 on the Snellen scale, using both eyes together.
- What does 6/12 mean? The Snellen chart is the classic chart with rows of letters. 6/12 (or the decimal equivalent 0.5) means you can see at a distance of 6 metres what a person with ‘normal’ vision can see at 12 metres.
- What if I only have sight in one eye? The rule still applies. You must meet the 6/12 standard in your one good eye.
Standard 3: An Adequate Field of Vision
This is the ‘silent’ risk and, in many ways, the most important standard.
Your field of vision (or visual field) is what you can see out of the ‘corners’ of your eyes without moving your head. Many conditions common in older age, like glaucoma, can cause you to slowly lose this peripheral vision. You often won’t notice it in your day-to-day life, but it’s critically dangerous for driving, as you may not see a cyclist, pedestrian, or car approaching from the side.
The legal standard requires a horizontal field of at least 120 degrees. You cannot test this yourself; it requires a specialist “visual field test” at an optician.
Renewing Your Licence at 70: A Step-by-Step Guide
The new driving eyesight rules for over 70s in the UK make preparation key. Don’t wait for the D46P form to land on your doormat.
Your 3-Month Action Plan (Before Your 70th Birthday)
Follow this simple timeline to ensure a smooth, stress-free renewal.
- Book Your Eye Test: As soon as you are within 6 months of your 70th birthday, book a full eye test. Remember, free NHS eye tests are available for everyone over 60 in the UK.
- Ask the “Driving Question”: At your appointment, don’t just ask for a new prescription. Specifically ask your optician: “Am I legal to drive?” This ensures they will check all three standards—the number plate test, your visual acuity, and your field of vision.
- Get Your Certificate: After your test, ask for a copy of your results or a certificate that confirms you meet the DVLA’s standards for driving. This is the evidence you now need for your renewal.
- Receive Your Renewal Form: The DVLA will automatically send you the D46P form (or an online reminder) about 90 days before your 70th birthday.
- Renew with Confidence: Complete the form (online or by post) and declare that you meet the eyesight standard, secure in the knowledge you have the official certificate to prove it.
How to Confidently Fill Out the Eyesight Section (Online vs. Post)
The D46P form (for postal renewals) or the online renewal service will ask you to declare that you meet the legal eyesight standards.
The wording is very precise. It will ask you to confirm you can read a number plate from 20 metres and that you do not have any notifiable medical condition (or that you have already declared one).
What Ticking “Yes” to the Declaration Now Means (Post-2025)
This is the critical change.
By ticking ‘yes’ or completing the online renewal, you are no longer just making a “good faith” declaration. You are now making a legal declaration that you have the supporting evidence (your eye test certificate) to prove you meet the three standards.
The DVLA will be conducting more rigorous checks and can ask you to provide this certificate. Submitting a false declaration is a serious offence.
Notifiable Eye Conditions: What You MUST Declare to the DVLA
One of the biggest sources of anxiety is “notifiable conditions.” Many drivers fear that telling the DVLA about a condition means an automatic, instant ban.
This is simply not true. In fact, declaring a condition is the best way to protect your licence.
The “Must Tell” List: Glaucoma, Cataracts, Macular Degeneration & More
You are legally required to tell the DVLA about any medical condition that could affect your ability to drive safely. For eyesight, the main conditions are:
- Glaucoma (if it affects both eyes, or one eye if you’re a bus/lorry driver)
- Cataracts (if they affect both eyes, or your one good eye)
- Macular Degeneration (specifically, if it affects both eyes)
- Diabetic Retinopathy
- Retinitis Pigmentosa
- Any other condition that causes a loss of your visual field.
You can check the full A-Z list of conditions on the GOV.UK website (Source 1.2).
What You Don’t Need to Report
You do not need to tell the DVLA if you are simply short-sighted (myopia) or long-sighted (hyperopia) and wear glasses or contact lenses to correct it. You also do not need to report colour blindness.
What Actually Happens When You Declare Glaucoma?
Let’s use glaucoma as the perfect example, as it’s the one people fear most.
- You Declare: You tell the DVLA you have been diagnosed with glaucoma in both eyes.
- The DVLA Responds: They will not immediately revoke your licence. Instead, they will write to you and your specialist (ophthalmologist) to get more information.
- The Test: They will almost certainly require you to take a specific visual field test. This is free of charge and is usually carried out at a local optician contracted by the DVLA (in most of the UK, this is Specsavers).
- The Result: The optician sends the test result directly to the DVLA’s medical team, who will assess if your field of vision is safe and wide enough for driving.
Here is the crucial, reassuring fact, confirmed by specialist charity Glaucoma UK (Source 8.1): Over 90% of drivers with glaucoma who take this test are found to be safe and keep their licence.
Declaring your condition and taking the test is the process that proves you are safe to drive.
What About Cataracts?
This is even more straightforward. If you tell the DVLA you have cataracts, they will note it. If your vision is below the standard, they may issue a temporary (e.g., 1-year) licence or advise you to stop driving until you have had surgery.
Once you have successful cataract surgery (which has a very high success rate), you simply update the DVLA with your new, improved vision, and your licence status is restored.
What Happens If You Don’t Meet the Standard?
Ignoring a problem with your vision is the fastest way to lose your licence and face serious penalties. The driving eyesight rules for over 70s in the UK are enforced for a reason.
The Police Roadside Test (“Cassie’s Law”)
If a police officer pulls you over (for any reason) and suspects your vision is poor, they can ask you to read a number plate from 20 metres.
- If you fail this test, they can revoke your licence on the spot.
- This power, known as “Cassie’s Law,” means your licence can be cancelled within hours, long before any court appearance.
Fines (£1,000) and Invalidating Your Car Insurance
If you are found to be driving with vision below the legal standard, you can be prosecuted and face a fine of up to £1,000.
Even more critically, if you have an accident and it’s found that your vision is sub-standard (or you failed to declare a notifiable condition), your car insurance will almost certainly be invalidated. This means you would be personally liable for all costs, which could run into millions of pounds.
When Your Optician Might Advise You to Stop Driving
If you have an eye test and your optician tells you that you are no longer legal to drive, you must stop. Continuing to drive against direct medical advice is indefensible, both legally and ethically.
Final Worlds
Renewing your licence at 70 (and every three years after) is straightforward if you are prepared. The driving eyesight rules for over 70s in the UK are not designed to take licences away, but to ensure everyone on the road is safe.
You must meet the three legal standards: the 20m number plate test, 6/12 visual acuity, and a full field of vision. The key 2025 change means you must now back this declaration with a recent, approved eye test certificate.
An eye test isn’t a threat to your licence; it’s the single best way to protect it. Early detection of conditions like glaucoma or cataracts is the key to managing them and staying on the road safely, and independently, for many more years.

FAQs
Do drivers over 70 have to take an eye test in the UK?
Yes. As of the new 2025 rules, you must provide a medical certificate or an eye test certificate (no more than 2 years old) when you renew your licence at 70 and every three years after. The old “self-declaration” system is no longer sufficient.
Can you self-certify eyesight at 70?
No, not anymore. This was the old rule. The 2025 regulations now require you to provide evidence from an optician or doctor to prove your eyesight meets the legal standard when you renew.
How far do you have to read a number plate for the DVLA test?
You must be able to read a new-style number plate (made after September 1, 2001) from a distance of 20 metres (about 65 feet).
What is the 6/12 vision test for driving?
This is the minimum visual acuity standard, measured on a Snellen chart (the letter chart) at an optician. It means you can see at 6 metres what a person with “normal” vision can see at 12 metres.
Do I need to tell the DVLA if I have cataracts?
Yes, you must tell the DVLA if you have cataracts in both eyes. You must also tell them if you have it in one eye and it affects your vision. Your optician will advise you, and you can update the DVLA again after successful surgery.
Do opticians have to report unfit drivers to the DVLA?
Only in specific circumstances. An optician’s primary duty is to you, the patient. They will advise you if you are not legal to drive. They only have an ethical duty to report you to the DVLA without your consent if they believe you are a risk to public safety and will continue to drive against their medical advice.
What happens if you fail the DVLA visual field test?
If you fail the DVLA-appointed test (e.g., for glaucoma), the DVLA will review your case. They may revoke your licence. However, you have the right to appeal this decision, which often involves taking another, more detailed test with an optician of your choice.
Will I lose my licence if I declare glaucoma?
This is the biggest fear, but for most people, the answer is no. According to Glaucoma UK, over 90% of drivers who declare their condition and take the required visual field test are found to be safe and keep their licence.
