This article creates two categories for individuals with vision ranging from 20/175 (6/52) to 20/50 (6/15). Statistically, there are approximately 532,000 drivers with vision ranging from 20/175 (6/52) to 20/100 (6/30) and 56,000 drivers with vision ranging from 20/80 (6/24) to 20/50 (6/15). The author contends that the plan to test the vision of a number of drivers over the next four years will turn up a large number of failures. This will result in the loss of licenses and conceivably cause many people to lose their jobs. One way to avoid this is to issue limited licenses. It is important for the Department of Motor Vehicles to consider this step.
本文将视力在20/175（6/52）至20/50（6/15）之间的个体分为两类。据统计，约有53.2万名驾驶员的视力在20/175（6/52）至20/100（6/30）之间，以及5.6万名驾驶员的视力在20/80（6/24）至20/50（6/15）之间。作者认为，在未来四年对一些驾驶员进行视力测试的计划将会发现大量不合格者。这将导致驾照被吊销，并可能使许多人失去工作。避免这种情况的一种方法是发放有限制的驾照。机动车管理部门考虑这一步骤很重要。
