A 48-year-old member asked:
Can anyone describe what "night blindness" is like? is it just haloes?

Nyctalopia: Standard experience for older folks with night blindness, is trouble distinguishing shapes and objects in the dark, and delayed accomodation to decreased illumination. Haloes may be due to glaucoma, and cataracts can cause light sensitivity at night with a shimmering effect. So, decreasing acuity at night may be a variable experience.
