1, the liver opens the orifice in the eyes “Su Wen – Jin Kui Zhen Shu” in the discussion of the five organs in the four seasons, the same qi, each has its own return: “the green color of the east, into the liver, open the orifice in the eyes, hide essence in the liver.” It is pointed out that the eyes are the orifice for the liver to communicate with the outside world. Therefore, the essence stored in the liver can be continuously transported to the eyes to nourish them, thus maintaining their visual function. The liver receives blood and is able to see. The liver is the main reservoir of blood and has the function of storing blood and regulating the amount of blood. Although the essence of the five viscera and six internal organs are all injected into the eyes, the eyes are the orifices of the liver, and the moisturizing of liver blood is especially important. Therefore, Su Wen – The Five Viscera Generation Chapter says: “The liver receives blood and can see”. The “Review of the Yaohuan – Eye as the most precious theory” further elaborates that “the liver in the ascending transport in the eye, light clear blood, is also nourishing the blood of the eye meridians.” It is also pointed out that blood is closely related to the sacred water in the eye, the sacred paste, the pupil god, etc. Blood nourishes water, water nourishes paste, paste protects the pupil god, in order to maintain the vision of the eye. 3, liver qi through the eyes The liver is the main drainage, has an important function of regulating the body qi. Qi can produce blood and fluid, and can move blood and fluid. All the blood and fluids that supply the eyes depend on Qi, and whether the Qi of the body is regulated is closely related to the main ascending and active characteristics reflected in the draining function of the liver. Therefore, the “Spiritual Pivot” says: “Liver qi is connected to the eyes, the liver and the eyes can distinguish the five colors”. This emphasizes that only when the liver qi is smooth and well-developed, the eye can distinguish colors and see things. 4, the relationship between the eye and the gall bladder The liver and gall bladder are in harmony with each other. The residual energy of the liver overflows into the bile, and is gathered into the essence, which is bile. Bile and the eye, very important. The secretion and excretion of bile are influenced by the drainage function of the liver. For example, the “Ling Shu” says: “When a person is fifty years old, the liver lobe begins to thin, the bile begins to decrease, and the eyes become unclear.” On the basis of the discussion of the “Ling Shu”, the “Review of the Yaohuan – Eye as the most precious” says more clearly: “The sacred ointment, the ointment contained in the eye. The bile in the infiltration of the essence of the juice, rise in the upper, the accumulation and become, only to be able to cover the pupil god. This cream a decline, then the pupil God has damage.” From the above, we can see that the bile is reduced, then the divine ointment decay, the pupil god then lose maintenance.
