Abstract

A study on distant vision, visual sense and colour vision in 2,218 motor vehicle drivers in Inner Mongolia Region was carried out and the effect of age on vision was analysed. The results showed that vision in drivers diminish with increasing age and the age threshold for visual acuity was 45 years. This paper discusses the normal values of vision in two age groups of pre-and-after the threshold age line, and these results may offer a scientific basis for drawing up occupational examination standards for drivers at their posts or under training.
