Good vision is essential for safe driving and motorcycling. The law sets minimum eyesight standards that drivers and motorcyclists must meet. Eyesight problems become more prevalent with age, and the driving of older people is more likely to be impaired by eyesight problems.

There are no official estimates of the number of drivers and motorcyclists on the road with eyesight that fails to meet the minimum legal standards. However, some studies suggest 2% to 3% of drivers have vision below the minimum legal standards. Poor vision is only recorded as a contributory factor in less than 1% of reported road deaths and injuries, although this may be an under-estimate due to the difficulties in assessing whether poor eyesight played a role in accidents.
