Random eye tests have found that a staggering 1 in 10 drivers can barely read a number plate from the minimum distance required by law. Eyesight charity, the Eyecare Trust, teamed up with the police to carry our spot checks, the results suggest that 3.5 million drivers in Britain cannot see well enough to be safe on the road. With 1 in 9 drivers admitting they had never had their eyes tested and a further 20% of the drivers admitting it was at least 5 years since they had undergone an eye test.
