Same here, but when I do have my high-beams on, it's usually because I'm on a very dark and desolate road where I'm driving kind of fast and want to be able to see as far ahead as possible ... which means I want my night-vision to be at its best. And when I have something bright shining in my eyes, it kills my peripheral vision at the edges of a dark road. Think of what you see walking into a room when you first turn out the lights versus the much improved view that you have once your eyes adjust to the darkness and your pupils dilate accordingly. That's the reason I usually dim my interior lights very low and it really helps me identify potential hazards just off the road much faster (thinking of animals and such that may dart out in front of me).
