In order to achieve shaky focus, the muscles inside the eye and the muscles of the outer eye contract excessively, which can lead to stable fatigue and even vomiting . This does not mean that your eyesight will deteriorate.
There are rare occasions when you need to exercise your eyes. For example, if the muscles that move the eyeball are paralyzed, it is helpful to exercise in the direction of contracting the paralyzed muscles to strengthen the muscles . Or, if you have strabismus, exercising your muscles in the opposite direction of your strabismus can also help you recover from strabismus. Note. However, eye exercises cannot restore vision.
