In movies, we usually see pirates wearing eye patches. What usually comes to our mind is that probably they have lost one eye either due to fighting or any other reason.
Or even a style statement peculiar to pirates, probably a fashion or something.
The eye patch, that pirates used to wear, was not a style statement or a cover for a missing eye. But no. It was none of them.
So, what do you think it is?
It was a clever trick of some of the very intelligent pirates.
A recent study says that the human eye adapts to light within seconds when coming out from the dark. But it takes almost 25 minutes to become used to the dark if you’re coming in from bright light.

An example of this is when electricity is being cut off suddenly at night, at first, you wouldn’t be able to see anything, everywhere looks dark but as time goes on you will be able to see some objects around you.
But when you are in the dark and electricity is suddenly restored, your eyes adjust to it immediately.
Pirates had to live among light and dark. One minute they are on deck and the next they have to go below deck. So, some clever ones out of them use to cover one of their eyes.
Whenever they had to go into the dark, they used to shift the eye patch from one eye to the other. That eye already being used to darkness as a result of the patch, helped them to see clearly even in dark.
