Effect of Discomfort Glare on Speed Discrimination in a Simulated Driving Scenario

Good and stable driving skills, which highly rely on visual performance, are very important for traffic safety. Glare has been shown to have certain impacts on driving safety issues, such as driving in a low-sun condition or gazing into the headlamp of an oncoming vehicle. While disability glare causes reduced visibility of objects on the road which increases risky driving events, discomfort glare irritates visual perception and distracts visual attention which affects visual performance as well. In the present study, the authors investigate the potential effects of discomfort glare on motion perception. Participants performed speed discrimination tasks of a front vehicle with different speed set up in a simulated driving scenario under low-level luminance glare and no-glare conditions. Results showed that discomfort glare interfered in visual perception of motion and caused reduced detectability in speed discrimination. One should be aware of the misestimation of speed caused by discomfort glare when performing a driving task.
