This is a really big problem in Australia as well. I know many people (myself included) that find it far more dangerous driving at night due to being blinded by bright headlights than they were 10-15 years ago.
I thought it was a problem with my eyes and went to an ophthalmologist who told me there's nothing wrong with them - but that she hears this from people all the time these days and believe headlights to be dangerously bright.
Normal headlights seem to be gradually closing the gap to the equivalent of high beams. I wonder if high beams have also increased their intensity? Would potentially cause sight damage if so.
I've got to admit occasionally I think they are high beams and end up flicking my lights at them, maybe if enough people do that they might think something is wrong.
