What is the omen of the left eye jump in geomantic omen?

There are many sayings that the left eyelid jumps for money, and the symptoms between men and women are different. As the old saying goes, eyelid jump is a man's left girlfriend. If a woman's right eyelid jump means disaster, her left eyelid jump is wealth. In fact, these statements have no scientific basis. The reason for this situation is often the eye nerve beating caused by lack of sleep or harassment. The reason why people's eyelids jump is because there are two kinds of muscles in the eyelids, one is called orbicularis oculi muscle, which looks like a wheel and surrounds the left and right eyes. When the eyes contract, the eyelids will close, which is mainly dominated by facial nerves. Another is to lift the eyelid muscles, that is, when it contracts, the eyelids will open, which is caused by the oculomotor nerve. Once stimulated by external factors, at this time, they will not listen to the command of the brain, thus starting to act on their own, causing repeated contraction and even trembling, and clearly feel that the eyelids are constantly beating, which is what everyone calls eyelid jumping.
