A Review of Disability and Discomfort Glare Research and Future Direction
Disability and discomfort in the nighttime driving environment have long been a topic of research. Disability glare has been fairly well defined based on the physiology of the human eye and the behavior of light as it enters the ocular media. However, discomfort glare has been less defined. Discomfort glare is not based on a physical response but rather a psychological response. Some research has shown that a person’s response to a glare source is based more on his or her emotional state than on the light source itself. Several organizations and researchers have tried to establish a requirement which must be adhered to in order to reduce the influence of glare from opposing headlamps and overhead roadway lighting on the drivers. This remains an ongoing issue with both the Commision Internationale d’Eclairage and the Illuminating Engineering Society of North America. This paper is a summary of these research attempts and a discussion of the potential of achieving this goal with future investigations.
