Night Blindness Symptoms & Diagnosis

Symptoms

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.

Diagnosis

A doctor will give you a medical examination to determine the cause of your night blindness. Some of the things a doctor might do are:

• Ask detailed questions about your experience of night blindness
• Test the levels of vitamin A in your blood
• Give you an eye exam
• Ask about your medical history, including:
  • Diet
  • Medications
  • Use of corrective lenses
  • Family history of diabetes
