Subjective Refraction Test Using a Smartphone for Vision Screening

Suggested vision standards for drivers in the United States with vision ranging from 20/175 (6/52) to 20/50 (6/15)
Abstract:
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.
