成语“看朱成碧”语源南朝·梁·王僧孺《夜愁示诸宾》:“谁知心眼乱,看朱忽成碧。”语见唐·李白《前有樽酒行》:“摧弦拂柱与君饮,看朱成碧颜始红。”也作“看碧成朱”。大意为由于过分忧愁,所以视觉模糊,把朱红色看成碧绿色。形容心乱目弦,不辨五色。由于过分忧愁、疲劳、恐惧、心乱等生理因素以及噪音、强光、黑暗等环境因素,大脑皮层某些兴奋灶过度兴奋造成整个皮层分析综合功能障碍,会暂时产生视觉错误,看朱成碧。眼科专家研究表明、一个人当中毒或患重病时,由于新陈代谢严重失调,引起大脑皮层功能紊乱,更容易暂时产生视觉模糊,看朱成碧。而更严重的看朱成碧者是红色盲患者。从目前的医学水平分析,色盲尚无满意疗法。它是一种不可救逆的先天性色觉障碍。已知是先天遗传的,并且很有规律,例如父母都是色盲者,所生的儿子是色盲,女儿是带色盲者。带色盲者虽然本身不色盲,但结婚后所生的儿子半数是色盲,女儿半数是带色盲者。 Idioms “Look at Zhuchengbi ” Etymology Southern Dynasty, Liang Wang Monk 孺 “nostalgia Show Zhuobin”: “Who knows the mind chaos, see Zhu 忽 成 碧.” “See Tang Li Bai” Before the bottles of wine “ : ”Destroy string whistle column and Jun drink, see Zhu Chengbi red. “ Also ”to see Bacheng Zhu ".
