Test: Diseases - Question 19

Night blindness is caused due to the deficiencies of_______.

Detailed Solution for Test: Diseases - Question 19
Causes of Night Blindness:

  • Vitamin A Deficiency: Night blindness is often caused by a deficiency in vitamin A, which is essential for healthy vision. Vitamin A helps the eye convert light into a signal that can be interpreted by the brain, allowing us to see in low light conditions. Without enough vitamin A, this process is impaired, leading to difficulty seeing in the dark.


Role of Vitamin A in Vision:

  • Rhodopsin Production: Vitamin A is a key component of rhodopsin, a pigment in the eye's rod cells that helps with night vision. Without enough vitamin A, the production of rhodopsin is reduced, making it harder for the eyes to adjust to low light conditions.

  • Protection of the Cornea: Vitamin A also plays a role in maintaining the health of the cornea, the outermost layer of the eye. A deficiency in vitamin A can lead to dry eyes, corneal damage, and other vision problems.


Prevention and Treatment:

  • Dietary Sources: To prevent night blindness and maintain healthy vision, it is important to include vitamin A-rich foods in your diet, such as carrots, sweet potatoes, spinach, and liver.

  • Supplements: In cases of severe vitamin A deficiency, supplements may be recommended by a healthcare provider to restore adequate levels of this essential nutrient.


By addressing the underlying vitamin A deficiency, night blindness can often be reversed, and overall eye health can be improved. It is important to consult with a healthcare professional if you are experiencing symptoms of night blindness to determine the best course of action for your specific situation.
