LED Streetlamp Glare

Caption

To investigate the effect of LED streetlights on the discomfort glare perceived by drivers, researchers from China and the Netherlands devised a laboratory set-up to mimic visual conditions on the road. The volunteers were asked to rate their level of discomfort with the glare on a standard deBoer 9-point rating scale, ranging from unnoticeable to unbearable. This photo shows a road with LED streetlamp glare where the researchers validated their laboratory findings.
