《诸病源候论》说：所谓清盲，是指眼睛原本没有异常，瞳仁黑白分明，只是看不见物体罢了。如果脏腑虚弱，风邪、痰饮乘虚而入，就称为清盲。
《眼论》说：有人眼睛突然感到昏暗模糊，没有明显原因，不痛不痒，逐渐视力下降，经过多年岁月，最终导致失明。
又有人说：清盲这种病，发病根源在于内部。有障翳形状像凝固的油脂，大小如楮树果实，漂浮在眼球内部，在水中游动，正好遮挡住瞳孔。那些虚妄的言论，荒谬的说法，即使花费千万钱财，最终也治不好一个病人。即使是扁鹊起死回生，华佗能解剖筋骨，这些人都只是偏执于某一方面的学问，各自擅长一种技术。至于治疗清盲内障，他们就束手无策了。
《治眼方》中治疗眼睛清盲、视物不见、斑翳浮动的“斑浮鸠散”方：
斑浮鸠（一只，按照食用方法处理，烤熟） 决明子（半升） 细辛（二两） 防风（二两）
以上四味药，切碎，密封存放十五天，然后晒干，研磨过筛，用酒送服一方寸匕的药量，每天三次，夜间两次。
又说：治疗清盲、三十年视物不见的方子：
细辛（一分） 萤火（十二枚） 芜菁子（一升） 鲤鱼胆（三枚）
以上四味药，将芜菁子、细辛、萤火研磨过筛，用鱼胆汁调和，如果不够稠，加入人乳增加粘度，制成梧桐子大小的丸药，每次服用三丸。
另一个方子：猪胆（一枚）
仅这一味药，用微火煎煮，使其能够制成黍米大小的丸药，放入眼中，片刻时间即可见效。如果是刚开始生成的翳膜，宜少量敷用，不可过多。
The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Manifestations of All Diseases) states: Qingmang (clear blindness) refers to a condition where the eyes originally appear normal, with clear distinction between the pupil and the sclera, yet the patient cannot see objects. If the internal organs are deficient and wind-pathogens, phlegm, or fluid retention take advantage of this deficiency, it is termed Qingmang.
The *Yanlun* (Treatise on Eyes) states: Some people suddenly experience dimness and obscurity in their vision without an apparent cause; there is no pain or itching, but vision gradually deteriorates. After many years, this leads to total blindness.
It is also said: The onset of Qingmang originates internally. There may be an opacity resembling solidified fat, as large as a paper mulberry fruit, floating within the eye and moving in the aqueous humor, directly obstructing the pupil. Empty talk and absurd theories, even if thousands of coins are spent, will ultimately fail to cure a single patient. Even if Bian Que could revive the dead or Hua Tuo could dissect sinews and bones, these practitioners merely specialize in one aspect and excel in only one technique. Regarding the treatment of internal cataracts (Qingmang), they are left helpless.
The *Zhiyan Fang* (Formulas for Treating Eyes) provides the Banfu Jiu San (Spotted Floating Dove Powder) for treating eye Qingmang, loss of vision, and floating opacities:
Banfu Jiu (one dove, processed according to culinary methods, roasted until cooked) Shuomingzi (Cassiae Semen, half sheng) Xixin (Asari Radix et Rhizoma, two liang) Fangfeng (Saposhnikoviae Radix, two liang)
These four ingredients are cut into small pieces, sealed, and stored for fifteen days, then dried, ground, and sifted. Take one fangcunbi (a square-inch measure) with wine, three times daily and twice at night.
It further states: A formula for treating Qingmang with thirty years of blindness:
Xixin (Asari Radix et Rhizoma, one fen) Yinghuo (Lampyris/Cantbrides, twelve specimens) Wuqingsi (Brassicae Semis, one sheng) Liyu dan (Cyprini Carassii Bile, three specimens)
These four ingredients are used. Grind Wuqingsi, Xixin, and Yinghuo together and sift. Mix with fish bile. If the consistency is insufficient, add human milk to thicken it. Form pills the size of wutong seeds (Catalpa fruits). Take three pills per dose.
Another formula: Zhu dan (Sus Scrofa Domesticus Bile, one specimen)
This single ingredient is gently heated over a low fire until it can be formed into pills the size of millet grains. Insert into the eye; efficacy is observed after a short while. For newly formed nebulae, apply sparingly; do not use excessively.
The *Qipo Fang* (Qibo's Formulas) treats human eye Qingmang where objects cannot be seen day or night:
Qinpi (Fraxini Cortex), Shengma (Cimicifugae Rhizoma), Huangqin (Scutellariae Radix) in equal parts. Boil in three sheng of water until reduced to one and a half sheng. Soak cotton in the decoction and apply/wash the eyes.
The *Duanju Fang* (Short Drama Formulas) treats eye Qingmang with loss of vision:
Use the bile and brain of a red carp, mix with Zhenzhu (Pearl), and apply using cotton inserted into the eye.
