With the accelerated pace of modern study, work and life, the popular application of television and electronic computers, the increasing time of human eye use and the relative shortening of the distance of seeing things, as well as the influence of the deteriorating natural ecological environment, visual fatigue has become one of the common clinical symptoms in ophthalmology nowadays. As visual fatigue brings many inconveniences to patients’ work, study and life, how to prevent, treat and recuperate visual fatigue has become a common concern of the ophthalmology industry and modern people. This paper discusses the prevention and recuperation rules of visual fatigue based on the theory of Chinese medicine health care and clinical practice. I. Chinese medicine’s understanding of visual function and visual fatigue Chinese medicine believes that the reason why the eye can see everything and recognize the five colors must depend on the upward infusion of the essence of the five viscera and the six internal organs, the heart is the master of blood, the liver collects blood, the heart blood is sufficient, the liver blood is flourishing, the liver qi is well organized, the essence of the five viscera and the six internal organs stored in the kidney can be transferred and transported by the qi of the spleen and the lung, and injected into the eye along the meridians, and under the support of the heart and the mind, the normal physiological function is performed. As the book “Ling Shu? Dazhong Lun says: “The essence of the five viscera and six internal organs are all injected into the eyes as the essence”. The “essence” refers to the visual function of the eyes. It can be seen that the normal visual function cannot be separated from the internal organs by the collection and transformation of the essence, qi, blood, fluid moistening and the mastery of God. If the internal organs are dysfunctional, the essence cannot be adequately and smoothly injected into the eyes, it will affect the visual function. Visual fatigue belongs to the category of “liver strain” in Chinese ophthalmology, “Introduction to Medicine? Miscellaneous disease classification? Eye” pointed out: “reading stitches excessive and pain, called liver labor. The eye is the orifice of the liver, born in the kidney and used in the heart, and its pathogenesis is mainly related to the liver, heart and kidney. In addition, “Huang Di Nei Jing Su Wen Jie Zhi Fa Wei” believes that “those who look at the eyes for a long time will strain the heart and therefore hurt the blood”. The review of Yaohuan? The two internal and external obstacle theory” a more comprehensive discussion of the cause of the disease: “the heart is hidden in the gods, transporting light in the eyes, where reading and writing, and couples of women tracing thorns, craftsmen carved calluses, all of which are to the eyes without turning and see, but also must stay in the heart of the internal camp. The heart is the main fire, the internal camp does not rest, then the heart fire moved. When the heart fire is moving, the eyes will be faintly painful”, that “kidney water deficiency is weak since the person, it is difficult to regulate”. Western medicine believes that the occurrence of visual fatigue is related to the improper use or excessive tension of the eye muscles, which are dominated by the spleen. It can be seen that visual fatigue is mostly caused by long-viewing strain on the heart and mind, damage to the spleen and depletion of qi, or labor and vision, liver and kidney essence and blood deficiency, unable to moisten the eye orifice. The main symptoms are dry eyes and discomfort, swelling and pain in the eyes and forehead, and even dizziness and headache, as well as irritability and vomiting after prolonged close work or study. After rest, the symptoms are relieved; at the same time, it is closely related to the patient’s tolerance, age, general health, mental state, nature of work, work tolerance time, working environment and living conditions; patients with myopia, farsightedness, astigmatism and old vision are more likely to have visual fatigue symptoms. The basic principles of TCM health care are to coordinate the internal organs, smooth the meridians and channels, purify and nourish the mind, abstain from desire and keep the essence, regulate the rest and nourish the qi, comprehensive conditioning and perseverance. Therefore, the adjustment and rehabilitation of visual fatigue mostly use traditional eye care, massage, eyes closed, diet and medicine, and so on, and apply modern scientific and technological achievements, so that they can be constantly improved. (a) Correction of refractive error Refractive error includes myopia, hyperopia, astigmatism and presbyopia; it is the most common cause of visual fatigue, and many patients with visual fatigue do not know they have refractive error or do not realize that the prescription of the glasses they previously wore has changed, while patients aged 40-50 think they do not need to wear fancy glasses yet. Therefore, they are resistant to refractive examinations proposed by ophthalmologists. Patience and psychological counseling should be done for patients with visual fatigue who may or may not have myopia, hyperopia, astigmatism, and presbyopia, so that they can have a timely optometric examination to understand their refractive status. If they have refractive error, presbyopia or unsuitable lens prescription, they should be guided to wear glasses with suitable prescription and high quality lens material, and be introduced to the correct method of wearing and maintaining glasses. Most patients with visual fatigue can eliminate it in a short time by wearing glasses to correct their vision. (B) close the eyes to nourish the mind. Historic health scholars have advocated that “the eyes should not see” and “the eyes should not see delusionally”. It is believed that “long vision hurts the blood” (“Su Wen”), “the eye, the house of the gods, the eye should always close, close is not faint” (“Health Four”), the eye of the gods should be kept inside, only beneficial to the coordination of form and spirit, long vision delusion is easy to consume blood and hurt the gods. “The heart wants to seek quiet, must first control the eyes, suppress the eyes, so that the return to the heart, then the heart is quiet and God is also quiet” (“Laozi”). As you can see, the eye and nourish the gods are closely related, in daily life, study, work, should not use the eyes for too long, especially not excessive close reading and work. Close the eyes and nourish the mind is a simple and effective way to prevent and relieve visual fatigue, especially for those who have refractive error, prolonged close use of vision, if persistent, daily morning, noon and evening meditation with eyes closed once, 5-10 minutes each time, the eyes must be closed when the whole body natural relaxation, excluding distractions, the effect is quite good. (3) Drugs for eye care Visual fatigue is closely related to the spleen, liver, kidney, qi and blood, and is commonly used in clinical practice to benefit the qi, strengthen the spleen, soothe the liver, tonify the kidney and nourish the blood. However, the prevention and treatment of visual fatigue need a long process, and the method of administration should be adapted to and conducive to the study and work of patients. We mostly use Chinese medicine pills, capsules and oral liquids, which are characterized by easy administration and long duration of effect and are mostly acceptable to patients.

In case of treatment, a course of treatment should be taken for 3 months, stopping for 15 days, and then a second course of treatment.

Moderate stimulation, no needle retention. 2, ear acupuncture: (e) eye electric control Chinese medicine ion introduction method eye electric control Chinese medicine ion introduction, through the dual action of direct current and drugs, increase the blood circulation of the eye, improve the oxygen supply and nutrient metabolism of the regulating muscle, accelerate the relaxation of the ciliary muscle, is conducive to the prevention and relief of visual fatigue, and has a fast action, less drug dosage, no damage, no pain, no side effects, can eliminate the patient’s psychological barriers, the effect is accurate, etc. The effect is precise. Danshen liquid, Chuanxiongzin liquid, Astragalus liquid and Dangxian liquid can be used as the introduction drugs according to the symptoms. Danshen, Chuanxiongzin, Radix et Rhizoma and Astragalus ions have the effect of relieving muscle spasm and improving blood circulation in the eyes. (E) Life conditioning Exercise to enhance physical fitness. Pay attention to the combination of work and rest, avoid long hours of close reading and work to prevent excessive room labor, depletion of essence and injury.

(F) diet and conditioning Pay attention to maintaining a balanced nutrition and a healthy body, which can reduce the chance of visual fatigue. Appropriate dietary therapy can help prevent and treat visual fatigue. (vii) Mental health care Excessive fatigue, lack of sleep, anxiety and mental tension can easily cause visual fatigue. Patients should be instructed to maintain a normal psychological state and to be contented and happy. (H) Adjustment of the environment 1. Reasonable design of the working environment, especially the design of lighting conditions. Lighting intensity is directly related to visual fatigue, too strong or too weak lighting will cause eye discomfort, resulting in eye pain and headache. But reasonable lighting intensity and vary from person to person, for example, in the same lighting intensity, some people can get good vision and no eye discomfort, but sensitive people may not work, eye discomfort or eye pain, etc.. Therefore, close work and reading should be good lighting, do not read and work in the direct sunlight or inadequate lighting. Desk lamp should be selected to adjust the brightness, and placed on the left front of the desk to avoid the right hand blocking the light source, and advocate the use of soft light bulbs. 2, with the development of modern society, but environmental protection has not attracted sufficient attention to human beings, the natural ecological environment is deteriorating, especially in large cities, urban construction planning is not reasonable, tall buildings, narrow roads, too small green areas, serious atmospheric pollution, living and working in such an environment, it is easy to visual fatigue phenomenon. Therefore, in addition to appealing to society to pay attention to environmental protection and protect the ecological environment, on weekends or holidays, you should go to the countryside in the green hills and water, climb up to the top and breathe fresh air, which is beneficial to the prevention of visual fatigue.
