The DVLA vision standard is woefully low. The average person (average, not "normal healthy") has 6/6 vision but the basic standard is half that, at 6/12.

Many people with 6/6 vision say they have perfect eyesight, they don't - their vision is as poor as an average person.

SWMBO has major eye problems for which we spend an inordinate amount of time at our regional specialist eye hospital - she hasn't driven for some years because of deteriorating eyesight which is now down to 6/6 but still twice as good as the legally required minimum!
