Night blindness is caused by a disorder of the cells in the retina that are responsible for vision in dim light (cones). There may be several common causes:

  • Lack of vitamin A, which can cause a disorder of the retina
  • Cataracts, which are cloudy areas in the lens of the eye
  • Some forms of retinal degeneration, such as retinitis pigmentosa
  • Certain medications
  • Birth defects
