Mentioned even in old Egyptian texts, night blindness is a condition that has concerned human beings since centuries. Watch out for night blindness symptoms and get your Vitamin A deficiency checked!

Key Takeaways

  • With night blindness, the quality of your low-light vision decreases
  • Night blindness is not a disease, but a sign of other health conditions
  • Only certain types of night blindness can be treated by doctors
Night blindness is perhaps the first-ever nutrient-deficiency condition to be distinctly identified by ancient Egypt texts from 1500 BCE [1]! It is a condition where an individual experiences a rapid decrease in the quality of vision at night. One may also experience night blindness symptoms in dimly lit places. If you suffer from night blindness or nyctalopia, you may find it difficult to travel at night, be it while walking or by driving. Experts don’t call it a night blindness disease since it is not a disease by itself but rather a sign of other health conditions you may have. As a result, you can treat only a few types of night blindness depending on their sources, while the others are not treatable. In South India, maternal night blindness is a prevalent condition. This is majorly a concern among women pregnant with twins or those with five or more pregnancies that cover 20 or more weeks of gestation [2]. Read on to know the symptoms, causes, treatment options, and preventive measures for this condition.

Night blindness symptoms 

The only major symptom of night blindness is trouble seeing in the dark. If you go to a dimly lit area from a well-illuminated environment, you may find it difficult to see, and that also indicates this condition. Night Blindness

Night blindness causes  

When it comes to night blindness, deficiency of vitamin A, cataracts, usher syndrome, nearsightedness, and retinitis pigmentosa are its prime causes. In case you have pancreatic insufficiency, and you find it difficult to metabolize fats, you are at a higher risk of vitamin A deficiency, which can lead to night blindness. Apart from that, having high sugar also makes you vulnerable to eye diseases like cataracts, which can further cause this condition. Additional Read: Planning a Cataract Surgery?

Night blindness treatment options 

To get started with night blindness treatment, doctors will identify the source of the condition first. To do that, they may test the amount of vitamin A and glucose in your blood, as well as look for cataract and nearsightedness symptoms. To address nearsightedness, you may have to wear corrective lenses. In case a cataract is detected, doctors can remove it surgically. If your blood test shows a vitamin A deficiency, doctors may prescribe supplements that you need to take as directed. In case of high glucose levels, you may be asked to lead a more active life and limit your glucose intake. This helps bring these levels down. Remember that genetic conditions like retinitis pigmentosa are not treatable. In this, you or your loved ones suffer from these rare eye conditions; neither wearing corrective lenses nor getting surgery helps. If you have this condition, it is better not to drive at night.
