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(guò)對視覺(jué)負后像補色平衡原理的論述，著(zhù)重分析了視覺(jué)負后像在藝術(shù)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(shí)間，利用后像對準閱讀材料或精細作業(yè)，激發(fā)中心凹注視能力，改善注視功能，提高中心凹視力。
