Bright vehicle headlights can
create even more glare for drivers than previous lighting due to their brightness
and positioning. A couple of hints provided by researchers might help with this
issue. Simple suggestions such as keeping the windshield clean while using anti-glare
products, and using anti-glare devices commonly built into the rear-view mirror,
will provide some relief for nighttime road glare while driving. New and
emerging patents for nighttime glare are portable anti-glare screens, advanced
driver assistance systems, anti-reflective coatings for lenses, and anti-glare
panels with LED light panels that are positioned above the driver’s seat. With
headlamp heights reaching as high as 54 inches and as low as 24 inches, and the
intensity of light regulated be bright enough to reveal vehicles and persons at a
distance of 200 feet, road glare at nighttime will continue to be an issue.
