This article discusses defective eye sight and accident frequency. In 75 per cent of accidents at intersections at least one driver had a visual defect in one eye, and in 97 per cent of these cases the crash occurred on the side of the bad eye. Studies conducted at the University of Palermo have shown that in the case of a considerable difference between the two eyes, the binocular vision can sometimes be lower than the monocular vision of the better eye. Separate paragraphs briefly discuss, visual acuity, accommodation and convergence, estimation of speed and distance, adaptation to darkness, resistance to glare, colour vision, lateral dominance, and factors such as fatigue, alcohol, drugs and age. It is suggested that in addition to normal sight testing, drivers should be tested for binocular vision, near vision, and phoria. /TRRL/
