As part of the eyesight driving rules, you must wear glasses or contact lenses every time you drive if you need them to meet the ‘standards of vision for driving’.
You must tell DVLA if you have 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 have 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.
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 (with glasses or contact lenses, if necessary) a car number plate made after 1 September 2001 from 20 metres.
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 of 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 is 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 have 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 will 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 are successful, you will still have to pass the DVSA standard eyesight test at your next practical driving test.
Eyesight Test
Eyesight checks for drivers should be carried out at least every 6 months. A series of number plates can be used by hanging them to a wall area 20 metres from a designated (and marked) point. These number plates should be removable and if testing a number of drivers should be rotated throughout the test.
An eyesight test confirmation record should also be used whereby the driver signs to say he/she has undertaken the test and these records should then be retained on file.
Fields that should be completed on the form should include;
Driver Medicals
If you have to re-apply for your vocational licence due to age, the form D4 must be completed.
Most GPs no longer undertake these medical tests and where a GP will, it is unlikely that he/she will complete the Visual Assessment part on page 2. If this is the case, you will have to make an appointment at an Optician to have this part completed before attending your GP for the medical assessment to be completed.
There is an alternative to having to go to your GP for the D4 to be completed and that is via a regional network of Doctors who will usually complete the whole D4 form, including the eyesight check.
