The worst part is when the other headlights are so bright you have to make yours brighter to compensate. I have astigmatism and am literally blinded by these headlights while driving at night. I had to upgrade my own headlights to LED (still dimmer than these others) just so that I could still make out the road when they drive by. Because the way my eyes work the more my eyes adjust for darkness the more blinding a light is.
