Is there any basis for the usual "left eye jumping for money and right eye jumping for disaster"?

In life, people often use eyelids to predict good or bad luck. There is a saying in the Han nationality that "the left eye jumps for wealth and the right eye jumps for disaster". "Jumping in the left eye is a joy, jumping in the right eye is a curse", "Jumping in the left is a joy, and jumping in the right is a sorrow; Jump left and jump right to kill "and so on. According to the Five Classics, the ancient sun goddess Fuxi and the moon goddess were transformed from Pangu's left eye and right eye respectively, so the custom of "male left and female right" spread among the people. The ancient philosophers in China viewed natural things with the binary opposition theory of Yin and Yang, and regarded the big, long, upper and left as Yang, and the small, short, lower and right as Yin. The saying that "jumping with the left eye is a fortune, jumping with the right eye is a curse" evolved from then on.

Due to the differences between ethnic groups and regions, there is still a concept of "good or bad jumping" with local characteristics among the people. Among them, Ewenki people regard the upper eyelid jump as a good omen, and the lower eyelid jump as a sign of crying. In Xiuwu County, Henan Province, China, there is also a saying that men "jump with their left eyes and jump with their right eyes"; A woman is "the right eye jumps over the treasure, and the left eye jumps over the curse". In addition, in some areas, eyelid jump is described as twelve hours a day and seven days a week, and luck is analyzed according to happiness. If people are unlucky enough to encounter an ominous sign, people often put mats and grass sticks on their eyelids to break the ominous light.

In fact, the ancient people's "jumping eyes for good or ill luck" mainly came from people's worship of gods. The ancients generally believed that eyelid jumping was a sign of God. According to folklore, people have the essence of God in their eyes, and what they see can indicate good or bad luck.

However, there is no scientific basis for the so-called "jumping money with the left eye and jumping disaster with the right eye". Medically speaking, this eyelid jump is caused by abnormal contracture of eyelid muscles, which is mostly caused by factors such as mental tension, fatigue and lack of sleep.
