A big group of the people we think have high-beams may only have aftermarket replacement LED or other high output bulbs not rated for their vehicles light reflectors. High-beams are not always brighter but are only made to flood more area with the light compared to running lights that are made to be focused on the road.

“LED bulbs make the problem worse. While halogen filaments deliver 360-degree illumination, LED bulbs typically emit light with a pair of back-to-back 180-degree planes. When LED alignment gets skipped, oncoming drivers are blinded, as are drivers ahead of them in traffic. Poorly aimed headlamps are especially bothersome with pickup trucks and SUVs due to the vehicle height.” https://arstechnica.com/cars/2020/03/how-do-we-stop-people-blinding-other-drivers-with-aftermarket-leds/amp/

Alignment of these lights is a major issue too that I think should be addressed at every inspection as that can show if a cars lights are working properly and not just blinding oncoming traffic.

If find that the light is very glaring or hard on your eyes especially during early in the morning or late day you should see your eye doctor about any possible issues. My father (77) realized he had an issue when he kept thinking people had their high-beams on. Turns out he has cataracts.

Also Astigmatism is a possibility for people that feel everyone’s high-beams are on. You should see your eye doctor as it can be corrected. https://my.clevelandclinic.org/health/diseases/8576-astigmatism

I have a astigmatism that is annoying driving at night.
