Are they just not aimed properly? I don't think replacing headlights is something you should do unless you're a professional.

I don't drive much here in Switzerland but I haven't noticed a problem when I do drive, but in the USA when I drive, especially in rural areas it's a pain.

It's this. They aren't inspected for alignment. It's fairly obvious that you can't be blinded by a light unless it's being sent directly into your face or reflecting off a mirror and directly into your face.
