Night Blindness

Night Blindness: What Is It?

Also referred to as nyctalopia, night blindness is a condition that makes it difficult to see well in poor light or at night. While it is not a disease, night blindness is a symptom of another eye problem like nearsightedness that has been left untreated.

What Causes Night Blindness?

The issue comes from a retina cell disorder that allows you to be able to see dim light. There are many causes of night blindness, including the following:

  • Vitamin A Deficiency
  • Diabetes
  • Nearsightedness
  • Cataracts
  • Glaucoma
  • Glaucoma medications which close the pupil
  • Keratoconus
  • Retinitis pigmentosa

An eye doctor will perform a full examination to pinpoint the exact cause. In some cases, specialized tests may be ordered.

How Is Night Blindness Treated?

The treatment for night blindness will vary depending on the exact cause of the condition. Treatment may be simple, such as a new medication or a new prescription for eyeglasses. However, treatment may be more complex, such as surgery, especially in the event that the culprit is cataracts.
