黄帝问于岐伯曰∶余尝上于清冷之台，中阶而顾，匐匐而前，则惑。余私异之，窃内怪之，独瞑独视，
安心定气，久而不解，独转独眩，披发长跪，俯而视之，后久之不己也，卒然自止，何气使然？岐伯对曰∶
五脏六腑之精气，皆上注于目，而为之精，精之窠为眼，骨之精为瞳子，筋之精为黑眼，血之精为络，其窠
气之精为白眼，肌肉之精为约束，裹撷筋骨血气之精而与脉并为系，上属于脑，后出于项中。故邪中于项，
因逢其身之虚，其入深，则随眼系以入于脑，入于脑则脑转，脑转则引目系急，目系急则目眩以转矣。邪
其精，其精所中不相比也，则精散，精散则视岐，视岐见两物。目者，五脏六腑之精也，营卫魂魄之所常营
也，神气之所生也，故神劳则魂魄散，志
意乱。是故瞳子、黑眼法于阴，白眼、赤脉法于阳也，故阴阳合传而精明也，目者，心使也；心者，神之舍
也。故神精乱而不转，卒然见非常处，精神魂魄，散不相得，故曰惑也。黄帝曰∶余疑其然，余每之东苑，
未曾不惑，去之则复，余唯独为东苑劳神乎，何其异也？岐伯曰∶不然也，心有所喜，神有所恶，卒然相
惑，则精气乱，视误，故惑，神移乃复。是故间者为迷，甚者为惑。

黄帝向岐伯问道：我曾经登上清冷的高台，走到台阶中间回头张望，或者匍匐着向前爬行，就会感到头晕目眩。我私下对此感到奇怪，内心也觉得不可思议。如果独自闭眼或睁眼，安心定气，长时间无法缓解，就会感到独自旋转、独自眩晕；披散头发长跪不起，俯身向下看，过了很久还不能停止，突然之间才自行停止，这是什么气造成的呢？
岐伯回答说：五脏六腑的精气，都向上灌注到眼睛，从而形成眼的视觉功能。精气的汇聚处就是眼球，骨之精构成瞳孔，筋之精构成黑眼珠（虹膜），血之精构成眼络，气之精的汇聚处构成白眼珠（巩膜），肌肉之精构成眼睑（约束）。这些包裹和摄取筋骨血气精微的物质与脉道结合成为目系，向上连接于脑，向后出于项部。所以，邪气侵袭项部，恰逢人体正气虚弱，邪气侵入较深，就会随着目系进入脑部。进入脑部后引起脑转，脑转则牵引目系紧张，目系紧张就会导致目眩和旋转感。邪气干扰精气，使得精气不能相互协调，就会导致精气涣散，精气涣散就会出现视物重影，看到两个物体。眼睛是五脏六腑精气的汇聚处，也是营卫、魂魄经常营守的地方，神气产生的地方。所以精神劳损会导致魂魄涣散，意志混乱。因此，瞳孔和黑眼珠效法阴，白眼珠和红脉效法阳，阴阳协调配合才能目光精明。眼睛是心的使者；心是神志居住的地方。所以神志和精气紊乱就不能正常转动，突然看到不寻常的地方，精神、魂魄分散而不能相得，这就叫做“惑”。
黄帝说：我怀疑这种说法。我每次去东苑，没有不感到头晕目眩的，离开那里就恢复了。难道只有我去东苑才会劳神吗？为什么这么特异呢？
岐伯说：不是这样的。心中有所喜好，神志有所厌恶，突然相互迷惑，导致精气紊乱，视线错误，所以产生迷惑，神志转移后就恢复了。所以，轻微的叫“迷”，严重的叫“惑”。

Huangdi asked Qibo: "I once ascended a high terrace called 'Qingleng' (Cold Terrace). When I was halfway up the stairs and looked back, or when I crawled forward on my hands and knees, I felt dizzy. I privately found this strange and wondered about it internally. If I closed one eye or opened one eye alone, calmed my mind and regulated my breath, yet the dizziness persisted for a long time without resolving, causing me to feel as if I were spinning alone or seeing things rotating alone; if I let my hair down, knelt for a long time, and looked down, only to find that after a long while it did not stop, until suddenly it ceased on its own—what qi causes this?"
Qibo replied: "The essence of the five zang organs and six fu organs all ascend to the eyes, forming the visual essence. The gathering place of this essence is the eyeball. The essence of bone forms the pupil, the essence of sinew forms the iris (black part of the eye), the essence of blood forms the vascular network of the eye, the gathering place of the essence of qi forms the sclera (white part of the eye), and the essence of muscle forms the eyelids (constraints). These substances, which envelop and gather the essences of sinew, bone, blood, and qi, combine with the meridians to form the optic nerve system (Mu Xi), which connects upward to the brain and exits posteriorly at the nape of the neck. Therefore, when pathogenic factors invade the nape, coinciding with a deficiency in the body's righteous qi, and penetrate deeply, they follow the optic nerve system into the brain. Once in the brain, it causes vertigo (brain rotation); this rotation pulls the optic nerve system taut, and tension in the optic nerve system leads to dizziness and rotational sensations. Pathogenic factors disturb the essence, causing the essences to fail to coordinate with each other, leading to the dispersion of essence. When essence disperses, vision becomes double (Shi Qi), resulting in diplopia (seeing two objects). The eyes are the gathering place of the essence of the five zang and six fu organs, the constant dwelling place of Ying and Wei Qi, Hun and Po, and the birthplace of Shen Qi. Thus, mental fatigue causes Hun and Po to scatter and Zhi Yi (will and intention) to become chaotic. Therefore, the pupil and iris emulate Yin, while the sclera and red vessels emulate Yang. When Yin and Yang interact harmoniously, clear vision is achieved. The eyes are the envoys of the Heart; the Heart is the residence of Shen. Thus, when Shen and Jing are disordered and cannot rotate normally, suddenly seeing unusual sights causes Shen, Jing, Hun, and Po to scatter and lose their connection, which is termed 'Huo' (Confusion/Dizziness)."
Huangdi said: "I doubt this explanation. Every time I go to Dongyuan (Eastern Garden), I invariably experience dizziness, which resolves upon leaving. Am I the only one whose spirit is fatigued by going to Dongyuan? Why is it so specific?"
Qibo said: "No. When the Heart has preferences and the Spirit has aversions, sudden mutual confusion leads to disorder of Jing Qi and erroneous vision, resulting in 'Huo'. When the Spirit shifts away, recovery occurs. Therefore, mild cases are called 'Mi' (Lost/Confused), and severe cases are called 'Huo' (Dizzy/Confused)."
