Anyone with personal experience or info about night blindness or nyctalopia?

Hello. I have it, and i can't drive after it gets dark, because i can't see well enough. Most people do not go completely blind at night. You just can't see well enough to function. My vision is ok during the day, but when it gets dark, i can't see good at all. Like if i were to drive at night, i can't see the lines in the road, where the road curves, or ends, can't read any signs, and the only thing i do see, is headlights of other cars ( which really blinds me ), and the traffic lights ( but they are really blurry ). So i just stopped driving after dark because i don't trust myself anymore. That's really the only way it has affected my life so far.

My mother has this problem. She went to an eye doctor and he told her to start taking vitamin A and carrying around a flashlight.
