Abstract: Visual acuity and visual field is a necessary condition for safe driving. The current licensing authority's visual acuity and visual field standards are different in different country. The current licensing authority's visual acuity and visual field standards are met when a person demonstrates visual acuity better than 05 and an intact visual field extending horizontally at least 120 degrees in many countries. In the past two decades, a lot of researches have focused on the effects of vision on driving, the link between impaired vision and driving accident. These results concur with previous literature that driving accidents for drivers with impaired vision more than those with good vision and there was obvious significant correlation between visual acuity and the accidents. Recent studies have shown that there’re no difference in driving accidents between drivers with impaired vision and those with good vision. Therefore someone believes the driving accident was no significant correlation with visual function. These two contradictory findings may be due to safe driving is integration of a variety of factors such as people, vehicles and environmental factors. Future research for safe driving should involve not only the visual function, but other factors. (Int Rev Ophthalmol, 2014, 38: 145-149)
