Driving eyesight rules

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

This guide is also available in Welsh (Cymraeg).

You must tell 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 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.

Check if you need to tell DVLA about your eyesight problem by searching the A to Z of medical conditions that could affect your driving.

If you need an eye test

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

DVLA then considers all medical evidence provided as part of a driving licence application, including the result of the eyesight test. 

If you choose to get your eyesight test from somewhere else

You can submit the results of an eyesight test done by another optician as long as it includes an ‘Esterman visual test’. DVLA do not guarantee they will accept an eyesight test done by other opticians.

You’ll need to pay for the test yourself.

You could be prosecuted if you drive without meeting the standards of vision for driving.

Standards of vision for driving

You must be able to read a number plate from 20 meters away (about the length of 5 parked cars). You can wear your glasses or contact lenses if you use them for driving.

You must also meet the minimum eyesight standard for driving by having a visual acuity of at least 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 only, in that eye.

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

Lorry and bus drivers

You must have a visual acuity 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.

You must tell DVLA if you’ve got any problem with your eyesight that affects either eye.

You may still be able to renew your lorry or bus licence if you cannot meet these standards but held your licence before 1 January 1997.

The practical driving test eyesight test

At the start of your practical driving test you have to correctly read a number plate on a parked vehicle.

If you cannot, you’ll fail your driving test and the test will not continue. DVLA will be told and your licence will be revoked.

When you reapply for your driving licence, DVLA will ask you to have an eyesight test with DVSA. This will be at a driving test centre. If you’re successful, you’ll still have to pass the DVSA standard eyesight test at your next practical driving test.
