Causes of (and some solutions to) Night blindness

• One of the main causes for night blindness in impoverished countries is lack of vitamin A
• In America, it is mostly caused by retinis pigmentosa, a disorder involving the rod cells in the retina
  
• Night blindness can also be from birth defects, certain drugs, and other eye-related problems
• Most children in America get vitamin A shots when they are children, but in most countries, people cannot afford them
• Even when a person starts to get night blindness, they could prevent it by getting the shot
• But in impoverished countries, that person usually won't get the shot
  
• That is why a lot of children are blind in some countries
  
• Some foods that have a lot of vitamin A in them are carrots, potatoes, oranges, and more
• These foods won't cure night blindness, though
