If you need to wear glasses or contact lenses to meet the ‘standards of vision for driving’ you must wear them every time you drive.
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.
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.
The practical driving test eyesight test
At the start of your practical driving test you have an eyesight test. You’ll have to correctly read a number plate on a parked vehicle.
If you can’t pass the eyesight test you’ll fail your driving test and the test won’t 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 the Driving Standards Agency (DSA). This will be at a driving test centre. If you’re successful, you’ll still have to pass the DSA standard eyesight test at your next practical driving test.
