Night Blindness

Night blindness is a type of vision impairment also known as nyctalopia. People with night blindness experience poor vision at night or in dimly lit environments.

Symptoms of Night Blindness

  • Headaches.
  • Pain in the eye.
  • Nausea.
  • Blurred and cloudy vision.
  • Sensitivity to light.
  • Problem with remote viewing.
  • Walking around the house in the dim light is a challenge.
  • Driving at night seems to be very difficult. It is deceptive to see a face in dim light.

Causes

  • Nearsightedness, blurred vision when looking at faraway objects.
  • Glaucoma.
  • Glaucoma medications that close the pupil.
  • Cataracts, or clouding of the eye’s lens.
  • Diabetes.
  • Retinitis pigmentosa which occurs when dark pigment collects in your retina and creates tunnel vision.
  • Vitamin A deficiency, vitamin A also called retinol, plays a role in transforming nerve impulses into images in the retina. The retina is a light-sensitive area in the back of your eye.

  2. If your vitamin A levels are low, your doctor might recommend vitamin supplements.
