Do carrots really improve your eyesight?

Claim: eating carrots improves your vision.

Status: false.

Turns out that in World War II, Britain's air ministry spread the word that a diet of carrots helped pilots see Nazi bombers attacking at night. That was a lie intended to cover the real thing responsible for their successes: Radar. British Intelligence didn't want the Germans to find out about the new technology, so they created a somewhat plausible-sounding explanation for the sudden increase in bombers being shot down. Further stories claimed RAF pilots were being fed lots of carrots to foster good eyesight.
