Did British propaganda claim carrots improved eyesight?

Question asked:

“During WWII British propaganda claimed that pilots ate carrots to improve their eyesight enough to see German plans from farther away, in order to conceal the British development of radar.”
True
Confidence: High Checked on October 20, 2026

Summary

During World War II the British Ministry of Information deliberately spread the story that pilots ate large amounts of carrots to enhance night vision, using it to explain the RAF’s success and to conceal the secret development and use of airborne radar. The myth was a propaganda tool, not a claim about actual visual improvement.

  • Did You Know? The Carrot-Vision Myth Was Actually a WWII Spy Operation - Media MICE

    During World War II, the British Royal Air Force (RAF) gained a decisive advantage with airborne radar technology, allowing pilots to detect incoming German aircraft before they became visible and dramatically improving nighttime interceptions.¹ But radar was a closely guarded secret. To conceal the technology from enemy intelligence, British officials promoted a different explanation for the RAF’s success: carrots.¹ The story became attached to RAF fighter ace John Cunningham, nicknamed “Cat’s Eyes,” who was credited with extraordinary nighttime accuracy against German bombers.¹ The government attributed his performance to diet rather than to the radar equipment guiding him.
