Question

Night blindness is caused due to deficiency of vitamin A
vitamin B
vitamin C
vitamin D​

Answer 1

Answer:

Vitamin A

Explanation:

1. Night blindness, also known as nyctalopia, is a condition which means your eyes are unable to adapt to low-light conditions.
2. This means that simple everyday activities, such as driving in the dark or popping to the bathroom during the night, become a lot more difficult.
3. The back of your eye – the retina – has different types of photoreceptor cells to help you see.
4. These are called rods and cones: rods are responsible for facilitating your night vision, while cones help your vision in bright light.
5. Night blindness usually occurs as a result of issues with your rod cells, although there are actually a number of causes of night blindness.

• People with vitamin A deficiency often suffer with night blindness.
• Vitamin A is needed for eye health and is essential for helping you process images.
