Trusting your eyesight to carrots

If you think these vegetables will improve your vision, think again. While carrots do contain vitamin A, which is a major player in keeping your eyes working properly, you really only need a small amount of it—and no matter how much vitamin A you consume, it’s not going to magically eliminate your need for glasses. In fact, if you eat too much vitamin A, you can end up with a toxic—although not usually fatal—reaction. The idea that more carrots means better vision might actually be a relic of a World War II-era military disinformation campaign. According to the online World Carrot Museum, British intelligence began spreading the myth during the blitz as a plausible explanation for why their fighter pilots were suddenly able to spot Nazi planes at night. In reality, the British had simply developed a better radar system and didn’t want the enemy to find out about it.
