Quick answers on NHS sight test intervals and DVLA vision standards, sourced from the current UK rules.
NHS sight test interval checker
Minimum interval
2 years
- Age 16–69: 2 years
Where more than one applies, the shortest (most frequent) interval is shown.
These are minimum intervals — an earlier NHS-funded test is available under the early re-test rules if there's a clinical reason (new symptoms, worsening pathology, or a GOC referral-management reason).

DVLA vision standards checker
Visual acuity
Must read a car number plate (post-September-2001 style) at 20 metres, with glasses or contact lenses if needed. Binocular visual acuity of at least 6/12 (decimal 0.5), with correction if needed.
Visual field
Horizontal field of at least 120°, with at least 50° to the left and right of fixation and at least 20° above and below. No significant defect within the central 20°. Usually assessed with a binocular Esterman test if there is any doubt.
The legal duty to notify the DVLA of a condition that may affect driving sits with the driver. An optometrist who finds a driver doesn't meet the standard should advise them clearly, in writing, and record it.
