The principle of visual negative afterimage supplementary color balance was introduced.The applications of visual negative afterimage in the artistic design were analyzed. 摘要通過對視覺負后像補色平衡原理的論述，著重分析了視覺負后像在藝術設計中的運用。
Flickering light increased the duration of the afterimage.Central fixation was stimulated by projecting the afterimage on detailed near work such as reading or sewing. 閃爍光背景增加后像持續時間，利用后像對準閱讀材料或精細作業，激發中心凹注視能力，改善注視功能，提高中心凹視力。
