*On December 22, 1940, the British Ministry of Agriculture released a statement urging the populace to eat carrots. “If we included a sufficient quantity of carrots in our diet,” the statement read, “we should overcome the fairly prevalent malady of blackout blindness.”

But the government had another motivation in pushing carrots: Great Britain faced food shortages due to wartime rationing, and carrots were plentiful and cheap. This led government agencies to tout them as having eye-strengthening powers as part of widespread campaigns aimed at getting the British public to eat carrots.*
