why do pirates wear eye patches joke

The fact that some pirates wore eye patches most likely had nothing to do with a missing eye, and everything to do with being able to seeвspecifically, above decks and below them. Jim Sheedy, a doctor of vision science and director of the Vision Performance Institute at Oregon's Pacific University,
Wall Street Journal that while the eyes adapt quickly when going from darkness to light, studies have shown that it can take up to 25 minutes for them to adapt when going from bright light to darkness, which " requires the regeneration of photo pigments. " Pirates frequently had to move above and below decks, from daylight to near darkness, and Sheedy says the smart ones "wore a patch over one eye to keep it dark-adapted outside. " When the pirate went below decks, he could switch the patch to the outdoor eye and see in the darkness easily (potentially to fight while boarding and plundering another vessel).

Arrrr We Sure? Though there are from history that state this as fact, there's no question that keeping one eye dark-adapted works.

В MythBusters tested this hypothesis in their pirate special in 2007 and (only the lack of historical sources kept it from being confirmed). At least one military manual for pilots "Even though a bright light may shine in one eye, the other will retain its dark adaptation, if it is protected from the light. This is a useful bit of information, because a flyer can preserve dark adaptation in one eye by simply closing it. " Even the a pilot should close one eye when using a light to preserve some degree of night vision. " Long ago, when sailing ships ruled the waves, a captain and his crew were in danger of being boarded by a pirate ship.

As the crew became frantic, the captain bellowed to his First Mate, Bring me my red shirt!. The First Mate quickly retrieved the captain's red shirt, which the captain put on and lead the crew to battle the pirate boarding party. Although some casualties occurred among the crew, the pirates were repelled. Later that day, the lookout screamed that there were two pirate vessels sending boarding parties.

The crew cowered in fear, but the captain calm as ever bellowed, Bring me my red shirt!. The battle was on, and once again the Captain and his crew repelled both boarding parties, although this time more casualties occurred. Weary from the battles, the men sat around on deck that night recounting the day's occurrences when an ensign looked to the Captain and asked, Sir, why did you call for your red shirt before the battle?. The Captain, giving the ensign a look that only a captain can give, exhorted, If I am wounded in battle, the red shirt does not show the wound and thus, you men will continue to fight unafraid.

The men sat in silence marveling at the courage of such a man. As dawn came the next morning, the lookout screamed that there were pirate ships, 10 of them, all with boarding parties on their way. The men became silent and looked to their Captain for his usual command. The Captain, calm as ever, bellowed, Bring me my brown pants!!
