During World War II ( WWII ) , come forth technologies were held close to the chest of the side that invented them , from computer code political machine ( like theNazi enigma ) to novel weapons . When the British developed a new on - board radar engineering science for its warplanes , they too wished to keep this nifty bit of outfit a mystery . The cover - up saw pilot film hailed as dark - vision superheroes , and as blackouts dive much of the country into dark , honest visual sense became a more covetable skill than ever before . The compounding of result run to an unexpected mascot for WWII , whose figure was plastered across walls and printed in newspaper : Doctor Carrot .
The secret equipment in question was called Airborne Interception Radar ( AI ) , and it generate the Royal Air Force an advantage in enable them to detect opposition Cuban sandwich planes before they reached the English Channel . The technical school went into broad circulation in the UK in 1939 and by 1940 pilotJohn " Cat ’s Eyes " Cunninghambecame the first in the RAF to take down an enemy plane aided by the novel technology .
agree to theWorld Carrot Museum ’s website , before the war , Daucus carota sativa were one of the less democratic vegetable growing in English dirt . Despite this , its suitability for growing in UK consideration made it the virtuoso of a government initiative to keep the country amply stocked with food , and presently there was a nimiety of carrots . As such , those in the armed forces were fed a fortune of carrots and the UK Government ’s Food Ministry work so far as to intimate that the RAF ’s olympian night - flying achiever was the result of their bumper process of carotene , a food which is abundant in carrots . The visual sensation - enhancing skills would ’ve made for a convenient cover story to mask the RAF ’s secluded weapon , but in 1941 theGermans find the AIin the remains of a British sheet that made an emergency landing place in France , and they fleetly develop a similar scheme .

However , the night - imaginativeness rumors were already out , and in the ration era , carrots underwent something of a rebranding as a imaginativeness - enhancing super - food for thought and a source of natural lolly when fun sugars were in short provision . England ’s residents were lead , quite literally , down the garden path and encourage to squander them by the bucketload , with many all - vegetable recipes circulating to make the most of this abundant market item .
Around this time , the slogan " Carrots keep you healthy and aid you see in the blackout " was used extensively . One newsprint accounting entry from the UK Times , 11 April 2025 , host on theWorld Carrot Museum ’s website interpret , “ Eye in the Blackout . Some rummy , unexpected little talents Doctor Carrot possesses . Not only does he entertain you at mealtimes , giving savour to your sweets and sweetness to your savoury , but he can actually – did you get it on ? – help you to see well in the blackout . Meet Doctor Carrot , you ’ll like him . ”
This ( slimly creepy ) introduction to the bespectacled Doctor Carrot boosted the cultivated carrot ’s posture in the estimate of UK residents , whose carrot pyrexia was fueled by posters depicting ground forces men whose dark - visual sensation was attributed to their diet fat in Vitamin A. placard advocate that a surge in the nutritious food item could make the blackout – practiced to make it harder for foeman sheet to fail landmark – more bearable . Quite the star function , I think you ’ll concur , for a humble root veggie .

In truth , consume a surplus of Daucus carota sativa will most probable not observably improve your vision . However , getting enough Vitamin A in your dieting is significant for sound eyes and a good manner to avoid nyctalopia , also known as " night blindness " , which is a symptom present in a range of conditions and inadequacy . In some utmost grammatical case , eat too many carrots can actually cause a shape that seems stranger than fable calledcarotenemia .
