glare is a common driving annoyance, whether it comes from the rising sun or setting sun or from headlights at night. A driver’s first instinct in this situation may be to squint or strain his or her eyes to cut the light, but that could make things worse.
Indeed, in 2012, nearly 1,300 fatal auto and motorcycle accidents resulted from glare and other vision-obscuring factors, according to the National Highway Traffic Safety Administration (NHTSA).
