Question

Night-blindness is due to the deficiency of ____________.

• A. True
• B. False
• C. Vitamin A
• D. Carbohydrates

Answer 1

The correct option is C

Vitamin A

One of the first signs of vitamin A deficiency is night blindness. Lack of vitamin A causes the cornea to become very dry, leading to clouding of the front of the eye, corneal ulcers and vision loss. Vitamin A deficiency also causes damage to the retina, which also contributes to blindness.
