Eating carrots will improve your vision, at least that’s what you have probably heard. This concept was popularized via wartime propaganda designed to explain why pilots were able to fly so well at night without revealing the new invention of radar technology to the enemy, but there is some truth to it as well.
The claim was made popular by the Royal Air Force during the 1940 Battle of Britain when a British fighter pilot named John Cunningham became the first person to shoot down an enemy at night with the assistance of radar technology.
Cunningham was given the nickname “Cat’s Eyes” due to his night time accuracy-thanks to his radar more than his eyes-and became the top British pilot during World War II while flying mostly night missions.
With the success of pilots like Cunningham the RAF decided to take his nickname a step further and told the media the success of their pilots at night was due to their heavy diet of carrots.
So is there any merit to the claim that carrots improve vision?
Well, carrots do provide vitamin A. which is essential for good vision, but very little is needed for healthy eyesight and there are many common foods that contain it as well.
Other common sources of Vitamin A include milk, cheese, and eggs. However, it is possible someone with a vitamin A deficiency could develop initial signs of night blindness.
Eating more carrots will not necessarily improve someone’s vision if their eyes are already healthy. If the person has a lack of vitamin A then there is a possibility that eating more carrots will improve their vision.
