Can Carrots Really Improve Night Vision?

During World War II, the British Air Ministry spread a rumor that carrots improve night vision in order to keep the invention of radar a secret from the Germans. But is there any truth to this rumor?

The answer is both yes and no. Carrots contain Vitamin A, also known as Retinol, which is necessary for the synthesis of Rhodopsin, a pigment in the eyes that helps with low-light vision. However, eating carrots will not significantly improve night vision for a person with normal levels of Vitamin A.

What is Retinol?

Retinol is important for the production of Rhodopsin, which helps with vision in low-light environments.

If someone has a Vitamin A deficiency, consuming more carrots could help improve their vision, but only to the point of a normal healthy person. It’s not worth overeating carrots like Bugs Bunny in hopes of having exceptional night vision.

Where Did the Carrot Myth Come From?

The rumor that carrots improve night vision was actually wartime government propaganda. The British Air Ministry spread the rumor during World War II to hide the existence of radar from the Germans. The rumor was so successful that it even fooled the British people and became a popular old wives tale.
