title: Three South African studies on the relation between road accidents and drivers' vision.
abstract: This report describes three studies of drivers' vision which have recently been carried out in South Africa. In the first, it was found that younger myopes constituted a substantial fraction of those drivers who failed to reach the acuity standards required for a South African driving licence: the acuity of almost all these drivers could be raised to an adequate standard by a proper refractive correction. In the second study, a comparison of the visual characteristics of a group of drivers who had been involved in accidents with those of a control group of accident-free drivers suggested that the former had mean acuities and depth perception which were worse than those of the accident-free group by small but statistically significant amounts. A third study, comparing the visual acuities of a group of randomly selected drivers with those of a group who had been involved in road accidents, showed that a higher proportion of the accident group had acuities which were below that required by the licensing authority.
