人的两只眼睛，就像天空中的太阳和月亮。日月有光明，照耀四面八方。如果烟雾遮蔽了天空，那么明亮的事物也会变得昏暗。人的双眼也是如此。只有当七情（喜、怒、忧、思、悲、恐、惊）在内部攻伐，六气（风、寒、暑、湿、燥、火）被外邪感应侵袭，再加上饮酒和房事过度，迎风远望，或者顶着热气奔跑，用生水洗脸，不知道自我爱惜，因此导致眼部疾病。
分而言之，上下眼睑都属于脾。眼皮发红、湿润、溃烂，是脾火上蒸所致。左右眼眦（眼角）都属于心。眼角肌肉绽裂、发红，是心火上炎所致。四周白色的巩膜部分都属于肺。白色部分出现红色血丝，是肺火上腾所致。黑眼球（乌轮）圆大肿胀疼痛，属于肝。两眼球肿痛，是肝火上冲所致。瞳孔内部昏痛，属于肾。两瞳仁昏花疼痛，是肾火上升所致。总而言之，都以肝为主宰。肝相火（寄居于肝胆的命门之火），一旦肝火发动，其他经络的火都会随之而动，疼痛于是发作。
然而又有眼泪多、流泪不止、瘙痒难忍的情况，这是风邪所致。风动摇了肝木，吹嘘鼓舞，所以眼泪不止。之所以流泪多，是因为泪为肝之液，风气流行则水流不止。之所以瘙痒难忍，是因为纯乎风邪而无火邪，所以只痒而不痛。
又有瞳孔散大、没有光泽的，是肾虚所致。肾水不足，无法滋养肝木；肝木无力，不能收敛精华，所以瞳孔散大且无光。又有视物昏花模糊的，是气虚所致。眼睛干枯少润泽的，是血虚所致。怕光亮喜欢暗处的，是虚损到了极点。眩晕不定的，是风痰壅盛所致。眼眶胀痛的是肝气旺盛所致。医生应当仔细审查并治疗：有火则泻火，有风则散风，气虚则补气，血虚则补血，虚极则补虚，风痰壅盛则消风去痰，肝气旺盛则抑制肝气、顺调气机。而凡是目疾，又以养血为关键。
然而古人说，五脏的精血，都禀受于脾，而上贯注于眼睛。所以调养脾胃是治疗眼病的上策。心的神志发露于眼睛，宜静而安养。劳累则会挟带相火妄行，扰乱君火之令，邪气并搏，自然失去光明。这是调养心脏以治疗眼病的根本。凡是大夫，应当以调理脾胃、以及养血安神，作为治疗眼病的根本。应当仔细审察。
The human eyes are like the sun and moon in the sky. The sun and moon possess brightness, illuminating all directions. If smoke obscures the sky, then what was bright becomes dark. Similarly, the two eyes can be affected. It is only when the Seven Emotions (Joy, Anger, Worry, Thought, Sorrow, Fear, Fright) attack internally, and the Six Qi (Wind, Cold, Summer-heat, Dampness, Dryness, Fire) are induced by external pathogens, compounded by excessive indulgence in alcohol and sexual activity, gazing into the wind, running while exposed to heat, washing the face with cold water, and failing to cherish oneself, that eye diseases arise.
Speaking specifically, the upper and lower eyelids belong to the Spleen. Redness, wetness, and ulceration of the eyelids indicate Spleen Fire steaming upward. The inner and outer canthi (eye corners) belong to the Heart. Cracking and redness of the canthal tissues indicate Heart Fire flaming upward. The white sclera surrounding the eyes belongs to the Lung. Red veins appearing on the white surface indicate Lung Fire rising upward. The large, round black eyeballs (Wulun) belong to the Liver. Swelling and pain of the eyeballs indicate Liver Fire rushing upward. The interior of the pupils belongs to the Kidney. Dimness and pain of the pupils indicate Kidney Fire ascending. In summary, the Liver takes the primary role. The Ministerial Fire residing in the Liver and Gallbladder, once activated by Liver Fire, causes fire from other meridians to follow suit, resulting in pain.
However, there are cases of excessive tearing, uncontrollable weeping, and unbearable itching, which are caused by Wind pathogen. Wind agitates the Liver Wood, blowing and stirring it, thus causing continuous tearing. The reason for excessive tearing is that tears are the fluid of the Liver; when Wind moves, water flows. The reason for unbearable itching is that it is purely Wind without Fire, hence causing itching but not pain.
There are also cases where the pupil is dilated and lacks luster, indicating Kidney Deficiency. Insufficient Kidney Water fails to nourish Liver Wood; consequently, Liver Wood lacks strength to converge its essence, leading to dilation and lack of luster. Cases of blurred vision indicate Qi Deficiency. Dryness and lack of moisture in the eyes indicate Blood Deficiency. Photophobia with a preference for darkness indicates extreme Deficiency. Vertigo and instability indicate Phlegm-Wind obstruction. Distending pain in the eye sockets indicates Exuberant Liver Qi. The physician must examine carefully and treat accordingly: if there is Fire, purge the Fire; if there is Wind, disperse the Wind; if Qi is deficient, tonify Qi; if Blood is deficient, nourish Blood; if Deficiency is extreme, tonify Deficiency; if obstructed by Phlegm-Wind, eliminate Wind and resolve Phlegm; if Liver Qi is exuberant, suppress the Liver and regulate Qi. For all eye diseases, nourishing Blood is essential.
As the ancients said, the essence and blood of the Five Zang organs are derived from the Spleen and ascend to the eyes. Therefore, regulating the Spleen and Stomach is the supreme strategy for treating eye diseases. The Spirit of the Heart manifests in the eyes and should be kept calm and nurtured. Fatigue will carry the Ministerial Fire to act recklessly, disrupting the command of the Sovereign Fire, allowing pathogenic factors to clash, thereby causing loss of clarity. This is the root of nurturing the Heart to treat eye diseases. Physicians should regard regulating the Spleen and Stomach, as well as nourishing Blood and calming the Spirit, as the foundation of treating eye diseases. They should examine this carefully.
