Standards of vision for driving

UK

  • 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 be able to read (with glasses or contact lenses, if necessary) a car number plate made after September 2001 from 20 metres away.
  • You must also meet the minimum eyesight standard for driving by having a visual acuity of at least 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 which can be tested by an Optician
  • You must pass the eyesight test before your driving exam begins.
  • 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.
  • This doesn’t include being short or long sighted or colour blind. You also don’t need to say if you’ve had surgery to correct short sightedness and can meet the eyesight standards.
