Question 1

Do I have to tell the DVLA I have glaucoma?

Accepted Answer

You must notify the DVLA if you have glaucoma in both eyes, or if you drive a group 2 vehicle (lorry or bus) and have glaucoma in either eye. If only one eye is affected and the other has a normal visual field, notification is not usually required — but you should still tell your insurer.

Question 2

How does the DVLA decide if I can keep driving?

Accepted Answer

The DVLA arranges an Esterman binocular visual field test at an approved centre. This measures your combined field of vision with both eyes open. The result is reviewed by DVLA medical advisors, who decide whether you meet the legal standard for driving.

Question 3

What are the visual standards for driving?

Accepted Answer

For a group 1 licence (car, motorcycle) you need an adequate binocular visual field and the ability to read a number plate at 20 metres (with glasses if needed). Group 2 licences (lorry, bus) have stricter standards including a higher visual acuity and a fuller field in each eye.

Question 4

What happens if I fail the DVLA field test?

Accepted Answer

If you do not meet the standard, the DVLA will revoke your licence. You must stop driving immediately. You can reapply if your condition improves or stabilises, and the DVLA will retest you.

Question 5

Can I drive with sight in only one eye?

Accepted Answer

Yes, monocular drivers can hold a group 1 licence provided the remaining eye has normal vision and an adequate field. You must notify the DVLA. Group 2 licences are not usually permitted for monocular drivers.

Question 6

Do I need to tell my insurance company?

Accepted Answer

Yes. You should inform your motor insurer of any diagnosed medical condition that could affect driving, including glaucoma. Failing to disclose may invalidate your policy.

Question 7

Will eye drops or laser treatment affect my driving?

Accepted Answer

Eye drops can cause temporary blurring after use — wait until vision settles before driving. After laser treatment (such as SLT or iridotomy) vision may be blurred for a few hours, so arrange transport home and avoid driving until your specialist confirms it is safe.

Question 8

How often will I need to be reassessed?

Accepted Answer

If the DVLA issues a licence based on medical review, it is usually granted for a limited period (often 1–3 years) and reassessment is required at renewal. Your consultant will continue to monitor your fields at regular clinic visits.
