Peripheral vision: Night blindness - usually means deficiency of vision in low light situations, like finding a seat in a dark movie theater, bumping into things in the dark. There is an effect on the rods, or light and dark sensing cells in the retina. A specialized test can be done to make sure these cells are working well, it's called a (dark adapted) electro-retinogram.
