What does "the left eye jumps over disaster and the right eye jumps over money" mean?

"Left eye jumps for money, right eye jumps for disaster" is a folk saying, which refers to the use of nerve movements of left and right eyes to predict bad luck. Eyelid jump, or chakra vibration (Chinese medicine name), refers to uncontrolled twitching and jumping of upper eyelid or lower eyelid, which is similar to eyelid spasm in western medicine and is more common in adults. Usually no treatment is needed. If the beating is too frequent or too long, you need treatment.
