During World War II, British intelligence spread the rumor that the Royal Air Force pilots enjoyed superior night vision because they ate copious amounts of carrots. Spoiler: it was a total lie. The truth was the RAF was using their newly invented radar to spot German planes in the dark. It was a massive military secret, and in order to keep German intelligence “in the dark” they made up the carrot fact.
Just to be clear, vitamin A in carrots is good for eye health…it just probably won’t help you detect enemy airplanes in the dark.
