Eating carrots gives you night vision
This myth, unlike the others so far, has some truth behind it. Carrots contain vitamin A or ‘retinol’. This is a substance that is required for your body to produce ‘rhodopsin’, the pigment in your eyes that comes into operation in low and poor lighting conditions. Having a deficiency in vitamin A can increase the risk of you developing nyctalopia, also known as night blindness. Eating carrots can help improve your vision in low-light but only up to the level of a regular person and unfortunately it won’t give you night vision. This isn’t exclusive to carrots either as asparagus, nectarines and apricots all also contain vitamin A.
Bonus fact: The origin of this myth is from the Air Ministry during the Second World War. They didn’t want the Germans to know that Britain was using radar when they intercepted bombers. To prevent this, they issued press releases saying that British pilots were eating more carrots giving them superior night vision. The British public fell for this hook line and sinker and as a result, so did the German high command and the myth lives on.
