Vsevolod [243]3 years ago
5 0

Answer:

C) vitamin supplements can reverse degenerative changes

Explanation:

Vitamin A is required for the formation of light-sensitive pigments in photoreceptors of the retina. Prolonged vitamin A deficiency causes a much-reduced level of rhodopsin resulting in night blindness. Also called nyctalopia, night blindness is an inability to see well at low light levels. Some of the rich sources of vitamin A are cod liver oil, milk, broccoli, eggs, etc. However, taking supplements and eating vitamin A rich food in the diet can reverse the condition.
