Pirates EYE

According to a vision scientist's theory, pirates did not wear blindfolds to cover their defective eyes, since they had to go up and down the ship's deck so often and quickly lead both groups of people up and down. Have good vision.

On deck, the scene was very bright under the glare of sunlight, and below deck, it was pitch dark. When a person enters a bright environment from a dark environment, his eyes quickly adjust to the bright light, but when the opposite happens, it takes a long time for the eyes to get used to the dark. These few minutes of time needed to adapt to the dark were sometimes a matter of life and death for pirates, but closing one eye would allow them to see much faster in the dark as soon as they went into the dark environment by removing the blindfold.

During their greatness and authority, the kings or rulers of Hormuz always controlled the area of ​​Muscat and an area in the Oman Sea and even a part of the southern shores of the Persian Gulf, which was later called the Pirate Coast, and in any order in this The enclosed areas and the southern banks of Iran prevented the operations of sailors and suppressed them when necessary, so it can be said that in the 15th century, sailors' activities remained more or less barren due to the existence of the rulers of Hormuz. After the end of the period of glory and power of Hormuz, the Portuguese and then the Safavid dynasty did not allow seafaring to mature in the Persian Gulf.
