Eating more carrots is indeed very helpful to human eyes, which has been proven by modern medicine. This is mainly because it contains a large amount of beta-carotene, which is converted into vitamin A after being ingested and digested by the human body. A long-term lack of vitamin A can lead to eye-related diseases.
Eating more carrots is indeed very helpful to human eyes, because the beta-carotene contained in carrots is very helpful in preventing night blindness, but this does not mean that eating more carrots can give you a pair of sharp eyes like a night owl. After all, night blindness and night vision are two different things.
Little bunny, white and white, loves to eat carrots and vegetables, hopping and jumping so cute. Er, in fact, not only little bunnies love carrots, carrots are also the favorite of the British Royal Air Force. Yo, where does this come from?
It turns out that during World War II, the British Royal Air Force once publicly promoted such a "secret recipe": their pilot John Cunningham, known as "cat's eye", had his outstanding night vision ability entirely because he ate a lot of carrots. It's against the heavens, so the secret to success is so simple! After this news was released, many British people began to grow and eat carrots in large quantities, because power outages were common during wartime, and good night vision ability would undoubtedly be much more convenient. So, the question is, can eating more carrots really enhance night vision?
Eating more carrots is indeed very helpful to human eyes, which has been proven by modern medicine. This is mainly because it contains a large amount of beta-carotene, which is converted into vitamin A after being ingested and digested by the human body. A long-term lack of vitamin A can lead to eye-related diseases, such as night blindness, which still plagues developing countries. Sufficient intake of vitamin A can also prevent eye diseases such as cataracts and macular degeneration. Beta-carotene is widely found in orange vegetables and fruits. In addition to carrots, sweet potatoes, mangoes, pumpkins, apricots, and cantaloupes are also rich in it. Milk, cheese, and egg yolks in daily food also contain a certain amount of beta-carotene. In addition to beta-carotene, the lutein in carrots also helps prevent macular degeneration.
Although carrots rich in beta-carotene are indeed very helpful to our eyes, especially in preventing night blindness, this does not mean that eating more carrots can give you a pair of sharp eyes like a night owl. After all, night blindness and night vision are two different things. Similarly, don't expect eating more carrots to improve your vision from 4.8 to 5.3. Moreover, it is best to eat carrots in moderation, because beta-carotene itself is actually a biological pigment. If you eat too much, it will turn your skin orange. Although this will not affect your health, I guess no one wants to turn themselves into a carrot color, right? If this really happens, just reduce the intake of beta-carotene, and it will recover naturally after a period of time.
Going back to the story mentioned at the beginning, since eating more carrots cannot enhance night vision, did the British Royal Air Force make a mistake? In fact, this was all a publicity strategy at the time. During World War II, the German Air Force often launched attacks under the cover of night. The British government protected its own important targets by implementing a blackout on cities and surrounding areas; at the same time, the British Royal Air Force used secretly developed and equipped radar technology to accurately locate German bombers in advance, winning the initiative in air combat. In order to cover up this fact and maintain their technical advantage for as long as possible, the British Propaganda Department staged this "scam that eating more carrots can enhance night vision" to confuse the enemy.
Think about it, if "eating more carrots can enhance night vision", everyone would have a pair of bright night vision eyes like a night owl, how terrifying that would be. However, according to the latest scientific research data, scientists in California, USA, have successfully developed night-vision eye drops, but this kind of eye drops is still in the small-scale testing stage and has not been promoted to the market. Think about it, it's really curious!
