It's not on purpose, believe me, it's more like a sharp stick in the eye. Not funny at all.

A yellowish filter on the lamp to remove the near UV would take care of the problem with no effect on lighting for the vast majority of people.

Note that dark window tint also prevents you seeing anything along with eliminating glare.
