When I learned to drive my instructor taught us a trick for when you're on a narrow road and are being blinded by oncoming headlights. In the US, most interstate highways, and often roads, will have a white line painted down the right side of the lane. Or you'll have barriers, or some other consistent delineator between road and not-road. You can often focus on that line when headlights approach and not lose your bearing even while being blinded. I've never forgotten that tip because it does work, and I use it almost every time I need to drive at night.
