论曰内经曰肝主目，又曰在脏为肝，在窍为目，难经曰，肝气通于目。目和则知五色矣
，内经又曰，心者、五脏专精也，目者其窍也，夫目既为肝之窍矣，又为心之窍何也。曰目
者、五脏之精华，固不专于肝也，所谓骨之精为瞳仁，筋之精为黑睛，血之精为络，窠气之
精为白睛，肉之精为约束是也。析而言之；则通乎五脏，合而言之，则主于肝，夫惟通乎五
脏，故曰精明五色者，气之华于此乎，观五脏有余不足，六腑强弱，形之盛衰，以此参伍，
决死生之分，夫惟主于肝，故肝虚寒，则目 视物生花；肝实热，则目痛如刺；肝中寒，
则目昏而瞳子痛；肝热冲睛，则目 赤痛；生息肉，不特如此。神志俱悲而泣下，则以水火
相感故也，一水不胜五火而目盲，则以阴阳各并故也。夫五脏阴阳，其变动俱感于目，又况
摄养失宜，动过生疾者耶，或多热食，或嗜五辛，或喜怒不时，或房室不节，以至凌寒冒暑
，处湿当风，哭泣不寐，凡过用目力，皆致疾病，其候不一，养生者不可不知也。
论曰：诸阳经的脉气都汇聚于头部，若风热之邪侵袭，则阳邪炽盛，发作于头皮与脑络之间，出现细密的小疮，颜色红赤且有汁液渗出，瘙痒疼痛并逐渐蔓延，甚至导致头发脱落，因此命名为“赤秃”。

论曰：《内经》说肝主司眼睛，又说在脏腑中属肝，在孔窍中为目；《难经》说，肝气通于目。目功能调和就能辨别五色了。《内经》又说，心是五脏精气之所聚，目是其外窍。既然目既是肝之窍，又是心之窍，这是为什么呢？回答说：目是五脏精华的汇聚之处，并不专门归属于肝。所谓骨的精华表现为瞳仁，筋的精华表现为黑睛，血的精华表现为血络，气的精华表现为白睛，肉的精华表现为眼睑（约束）。分析而言，目与五脏相通；综合而言，则主要归属于肝。正因为与五脏相通，所以说精明和辨别五色的功能，是气血荣华在此处的体现。观察五脏的有余和不足，六腑的强弱，形体盛衰，以此相互参验，可以决断生死界限。正因为主要归属于肝，所以肝虚寒时，视物会出现眼花；肝实热时，目痛如针刺；肝中寒时，目昏且瞳仁痛；肝热上冲于目，则目赤痛；生息肉等。不仅如此，神志悲伤而流泪，是因为水火相感所致；一水不胜五火而导致目盲，是因为阴阳偏盛所致。五脏阴阳的变化都会感应于目，何况调养失当、过度活动而生疾病呢？如多吃热性食物，嗜好五种辛辣之物，喜怒无常，房事不节，以至冒犯寒冷或酷暑，处于潮湿环境或迎风而坐，哭泣失眠，凡是用眼过度，都会导致疾病，其症状表现不一，养生者不可不知道这些道理。

It is said that the meridians of all Yang channels converge on the head. When wind-heat pathogenic factors invade, Yang pathogens become excessive and erupt between the scalp and brain collaterals, presenting as numerous small sores with a red color and exudate, accompanied by itching, pain, and spreading infiltration, eventually leading to hair loss. Hence, it is named "Chi Tu" (Red Baldness).

The *Neijing* (Classic of Internal Medicine) states that the Liver governs the eyes, saying that among the Zang organs it corresponds to the Liver, and among the orifices it opens into the Eyes. The *Nanjing* (Classic of Difficult Issues) states that Liver Qi connects to the Eyes. When the Eyes are harmonious, one can distinguish the five colors. The *Neijing* also states that the Heart is the concentration of the essence of the five Zang organs, and the Eyes are its orifice. Since the Eyes are the orifice of both the Liver and the Heart, why is this? The answer is: The Eyes are the gathering place of the essence of the five Zang organs and are not exclusively governed by the Liver. Specifically, the essence of Bone manifests as the pupil (Tong Ren), the essence of Sinew manifests as the iris (Hei Jing), the essence of Blood manifests as the blood vessels (Luo), the essence of Qi manifests as the sclera (Bai Jing), and the essence of Flesh manifests as the eyelids (Yue Shu). Analytically speaking, the Eyes connect with all five Zang organs; synthetically speaking, they are primarily governed by the Liver. Because they connect with the five Zang organs, it is said that clarity of vision and discrimination of five colors represent the brilliance of Qi and Blood at this location. By observing the excess and deficiency of the five Zang organs, the strength and weakness of the six Fu organs, and the flourishing and declining state of the body, through mutual verification, one can determine the division between life and death. Because they are primarily governed by the Liver, when Liver deficiency and cold occur, vision becomes blurred with visual hallucinations (seeing flowers); when Liver excess and heat occur, eye pain feels like needle pricking; when Cold resides in the Liver, vision is dim and the pupil hurts; when Liver Heat rushes upward to the eyes, the eyes become red and painful; polyps may grow, and other conditions arise. Furthermore, if the Spirit and Will are sorrowful and tears flow, it is due to the interaction between Water and Fire. Blindness resulting from one Water failing to overcome five Fires is due to the simultaneous accumulation of Yin and Yang. The changes of Yin and Yang in the five Zang organs all affect the Eyes. How much more so when improper nourishment, excessive activity, and disease generation occur? Such as consuming too many hot-natured foods, craving the five pungent spices, irregular emotions of anger and joy, immoderate sexual activity, exposure to cold or summer heat, dwelling in dampness or facing the wind, weeping, insomnia, and any overuse of visual effort—all can lead to disease. The manifestations vary, and those who practice health preservation must know these principles.
