[0002] Vision rehabilitation training is a method of improving vision or visual function through various special activities, exercises and tools. This training usually targets some vision problems, such as amblyopia, strabismus, eye fatigue or visual processing difficulties. The goal of vision rehabilitation training is to enhance the coordination, flexibility and adaptability of the eyes. Traditional eye training devices have a single training mode, usually providing a single target installed on a predetermined trajectory to move back and forth, and adjusting the distance between the target and the eye to stimulate the lens to focus and adjust to achieve the training purpose. Long-term training on the same target will make the eyes adapt to this specific mode, resulting in a weakened training effect.
