Astigmatism and Street Lights
Astigmatism is a common vision disorder that affects between 8 percent and 62 percent of the population, based on various studies. This condition significantly reduces quality of life by lowering visual acuity, increasing glare in 53 percent to 77 percent of cases, creating halo effects around light sources in 28 percent to 80 percent of cases, causing difficulties with nighttime driving in 66 percent of cases, contributing to falls, and leading to dependence on corrective eyewear in 45 percent to 85 percent of cases [1].
Astigmatism reduces visual sharpness and contrast sensitivity, which creates challenges for driving and pedestrian movement during low-light conditions. Street lighting technologies can help address these issues by compensating for the visual distortions, thereby easing the burden on affected individuals and potentially reducing demands on healthcare resources.
