Explanation: In WW2, Britain spread word that carrots improved night-time vision, and that its pilots were eating lots of carrots, in order to ‘explain’ why they were intercepting Nazi planes over Britain so reliably at night.

In reality, they’d figured out how to fit radar on their fighter planes, and wanted to keep that a secret for as long as they could. The hope was that Nazis keeping tabs on civilian British news would fall for the ruse, and buy UK plane radar a little more time undetected.

Carrots may prevent nutritional deficiencies that lead to poor night-time vision, but they aren’t going to make your MK1 eyeballs into NODs.

You know, I’ve heard that story a bunch of times, but nobody ever says the conclusion. How long did it work?

German who grew up in the 21st century here. The myth that eating lots of carrots will improve your eyesight/nightvision significantly is still more or less alive and well here. I sort of believed it until I saw a variation on this meme for the first time.

I’d say it seems to have worked pretty well.

As a millennial American, I was taught it as a child, and I’d estimate most people I know believe it to be true.
