Every driver stopped this month by one of three police forces in England will have their vision checked. During this time, drivers in Thames Valley, Hampshire and the West Midlands who are unable to read a number plate from 20 metres away will automatically lose their licence.
Police hope that this basic test will find people who continue to drive despite being unable to see well enough to react to a hazard in good time. The data collected during September 2018 will also give them a better idea of how many people are driving dangerously across the UK.
Although eye tests are recommended for most people every two years, Vision Express estimates that four in five drivers are overdue.
Our Sight Matters kit includes a voucher for a free eye test.
Having a macular condition does not automatically mean you have to stop driving, but you must tell the DVLA if macular disease affects both your eyes.
