Night blindness is caused by a lack of Vitamin A in the foods they eat because they eat basically rice. The reason they can't see has to do with the rod cells in their eyes without vitamin A these cells cannot produce a light-sensitive chemical called rhodopsin.
Night blindness is caused by a lack of vitamin A, often due to malnutrition. The rod cells (photoreceptor cells in the retina of the eye that can function in lower light better than the other type of visual photoreceptor) in these children’s eyes can’t produce rhodopsin, a light-sensitive chemical that helps us see in low-light.
The cause of night blindness is the lack of the vitamin A. Many children in pour, developing countries don't have access to a rich diet, which results in a a constant lack of vitamins. In this case, the lack of the vitamin A, that produces the appearance of night blindness.
The illness is caused by the impossibility of the body to create rhodopsin because of the vitamin A deficiency. Without this substance rod eye cells aren't able to see in low-light.
The cause of night blindness is a lack of vitamin A in the diet (this explains why this disease is very common in developing countries in Asia, where the children's diets consist almost entirely on white rice, which has no vitamin A).
The reason why the night blind people can’t see has to do with the rod cells in their eyes. Without vitamin A, these cells can’t produce a light-sensitive chemical (rhodopsin), that helps us see in low-light.
Night blindness is caused by a deficit in vitamin A, and it´s very common in developing countries because their main food is white rice (that has no Vitamin A). Without this vitamin the rod cells can´t produce rhodopsin that helps seeing in low light, causing night blindness.

the deficience of vitamin A in food provokes night blindness in children.

Night blindness is caused by a lack of vitamin A on many child's diets.
The rod cells from our eyes need vitamin A to produce rhodopsin, a low-light sensitive chemical.

Night blindness is caused by a lack of Vitamin A in children who live in developing countries.
