Is the folk saying "the left eye jumps over wealth and the right eye jumps over disaster" true? Why is there such a statement?

I think the left eye jumps for money and the right eye jumps for disaster, which is incorrect. This is just a rumor circulated by the ancients. Eyelid flutter doesn't represent what you expect. Eyelid pulsation is only caused by nerves. Medically speaking, there are two main reasons for beating eyelids. The first reason is that the eyes are too tired, and the second reason is mainly caused by illness. It has nothing to do with wealth or disaster.

Generally speaking, staying up late often leads to eye fatigue, which may cause eyelid pulsation, but under normal circumstances, eyelid pulsation is only a matter of several seconds. If the eyelid pulsation lasts for a long time, it may cause some eye diseases.

But there is an ancient saying that jumping with the left eye is wealth and jumping with the right eye is disaster. In fact, it has nothing to do with luck, but is based on the conclusions drawn by many people's experiments. However, these experiments are necessarily accidental, and not all of them are accurate. In other words, this sentence is unscientific.

But you can use this sentence to strengthen your psychological comfort in your daily life. Maybe you won't be so nervous when you meet some things, but some people may say that the beating of your eyelids is really related to your own good or bad luck. In view of this situation, I think it should be accidental

Maybe he really took this sentence as his psychological comfort, and compared it with everything he met, which led to this phenomenon. But this sentence is unscientific after all, and it is impossible to find theoretical support, so I don't think it holds water.
