Numerous patients struggle with seeing in the dark; this condition is called night blindness. Night blindness does not mean you are incapable of seeing at night, but that your vision is weaker in the darkness. It also affects how your eyes adapt from going to light to dark or dark to light settings and can take longer than normal to adjust. Patients that have night blindness show symptoms at birth or start to develop due to underlining vision problems such as cataracts, glaucoma, nearsightedness, or a vitamin A deficiency.

If you are not sure whether you have night blindness, consider the following questions:

  • Is driving at night becoming more challenging?
  • Do you avoid going outside at night for fear of hurting yourself such as tripping over an object?
  • Do you have a problem recognizing people’s faces in darkened settings?
  • Does it take your eyes a long time to adjust from light to dark or dark to light settings?
  • Do you struggle seeing anything in a darkened room, such as moving through your home at night even with small lamps on?

If you answer yes to any one of the above questions, schedule a comprehensive eye exam to help identify if you have a vision problem.



Night blindness can be treated, but it will depend on the cause of the condition. Treatment will consist of wearing corrective eyeglasses or contact lenses to provide support to your vision. Also, wearing prescriptive UV sunglasses during the day can give you added protection from the sun’s ultraviolet rays. These lenses will help to reduce further eye damage. Depending on the severity, your Optometrist may recommend that you avoid driving at night.
