          Abstract

          Periodic renewal of driver licenses is an integral part of the driver licensing procedures for most states. Renewal of driver licenses is usually required every 4 years, and many states conduct vision tests before granting renewal. A few states require additional testing, whereas several states have no vision testing or any other examinations at renewal. Still fewer have additional requirements for older drivers. The increasing percentage of older drivers and the visual changes due to aging or disease are also additional concerns. Thus, it was considered important to systematically review current practices regarding license renewal and retesting and identify potential changes in these procedures. For older drivers, a more frequent renewal period is proposed, accompanied by a vision screening and a medical questionnaire to determine physical and mental status of older drivers.

          Incidence of visual field loss in 20,000 eyes and its relationship to driving performance.

          Automated visual field screening of 10,000 volunteers (20,000 eyes) showed the incidence of visual field loss was 3.0% to 3.5% for persons aged 16 to 60 years but was approximately 13.0% for those older than 65 years. Approximately half of the persons with abnormal visual fields were previously unaware of any problem with peripheral vision. Follow-up results suggested that the most common causes of visual field loss were glaucoma, retinal disorders, and cataracts. Drivers with binocular visual field loss had accident and conviction rates twice as high as those with normal visual fields. Drivers with monocular visual field loss had accident and conviction rates equivalent to those of a control group. Our results have important implications for mass visual field screening to detect eye diseases and for vision-related factors in traffic safety.

            Vision, Aging, and Driving: The Problems of Older Drivers

            Although there are well-recognized declines in visual functioning with age, their contribution to the problems of older persons on tasks in the natural environment, including driving, are largely unknown. Adults ranging in age from 22-92 years were surveyed in regard to their visual difficulties when driving and performing everyday tasks. The visual problems of drivers increased with age along five different visual dimensions: unexpected vehicles, vehicle speed, dim displays, windshield problems, and sign reading. Several of the age-related visual problems that were reported appear to be related to the types of automobile accidents more common among older drivers. The study also replicated the findings from an earlier investigation of non-driving tasks that showed visual declines with age on five dimensions: visual processing speed, light sensitivity, dynamic vision, near vision and visual search. These findings indicate promising areas of research regarding the effects of visual aging on tasks in the natural environment.
