Problems of Nighttime Visibility and Glare for Older Drivers

This paper examines age-related changes in the visual system that may have a significant effect on the ability to drive at night. It begins with a description of changes in the eyes that occur with age and then explains how these changes reduce the ability to see low-contrast objects and increase the effects of glare. The results of a number of studies are described. The paper concludes with a section describing certain measures that can be taken to reduce these effects.
