Vision and driving: A look at the research road ahead

Research interest into the role of vision in road safety has greatly increased over recent years. This has been stimulated by the limited understanding of how visual impairment affects driving ability and safety, a lack of strong evidence on which to base visual licensing standards for driving safety, together with a growing reliance on driving for maintaining mobility and independence, particularly in older populations. This special issue on <i>‘Vision and Road Safety’</i> highlights the multidisciplinary nature of research in this area, bringing together researchers from optometry, vision science, ophthalmology, psychology, epidemiology, neurology, neurobiology and engineering, thus demonstrating the breadth of research questions in this area. However, while the research questions associated with this topic area included in this special issue are wide ranging, we identify clusters of papers that address common questions but using different methodological approaches..
