Night Blindness


Symptoms are difficulty or inability to see in low light or darkness. While driving, this may also occur a few seconds after the bright headlights of an oncoming car have passed.

Tests to diagnose: 
  • Refraction test to measure your prescription for eye glasses orcontact lenses
  • Slit lamp examination to examine the structures in the front of the eye, including conjunctiva, cornea, eyelids, iris, lens, and sclera
  • Retinal examination to look for any damage to the structures in the back of the eye ‒ the vitreous, retina, and choroid

Treatments generally include:

  • Taking vitamin A supplements
  • Having cataracts removed
  • Low-vision aids
