The effect of the extent of visual field upon driving performance has recently received a great deal of interest. With such a volume of traffic on the roads today, peripheral vision would seem to be essential for safe driving and yet past literature is inconclusive as to the relationship between the extent of visual field and driving performance. This paper reviews the research work and gives possible reasons for the lack of relationship reported in most of the studies. Until further research work does determine the minimum visual field required for safe driving, the role of the medical practitioner in advising patients when they are considered unsafe to drive is in question. The provision of a period of adaptation after complete loss of vision in a previously normal eye should also be considered, during which time the motorist is temporarily banned from driving.
近期，视野范围对驾驶性能的影响备受关注。如今道路上交通流量如此之大，周边视觉对于安全驾驶似乎至关重要，然而过去的文献对于视野范围与驾驶性能之间的关系尚无定论。本文回顾了相关研究工作，并给出了多数研究中所报告的缺乏这种关系的可能原因。在进一步的研究工作确定安全驾驶所需的最小视野之前，当认为患者驾车不安全时，医生向患者提供建议的作用受到质疑。对于先前正常眼睛完全失明后给予一段适应期的做法也应予以考虑，在此期间驾车者应被暂时禁止驾驶。
