Yep i have it ! My night blindness is associated with eye disease. I have had to have a sensor put outside my bedroom door so when i walk out the light comes one so i can find my way to the toilet. I also have other lights fitted through out the house, my office at home i had a downlight installed so i could see at night if i was typing, and one in the kitchen above my sink.
My eyes also Do not adjust straight away if i am going from being outside into work, or outside at home and coming inside. They take longer to adjust to the light / dark environments. I also have huge problems seeing different colours on different backgrounds.
