Abstract: living in a narrow space is not conducive to visual development. Animal experiments have proved that small animals living in a narrow environment are prone to myopia. In addition, parsinen et al. Proved that people with myopia participated in less sports activities in adolescence, but there was no significant difference in this regard in adulthood., When the eye is adjusted and relaxed, the parallel light passes through the ocular refractive system and focuses on the retina, which is called myopia. Myopia has increasingly become the focus of research, and its exact pathogenesis is not clear. Only epidemiological investigation shows that it may be related to a variety of environmental factors, so it is particularly important to prevent and reduce its occurrence., Lifestyle leads to myopia: 1. Continuous long-time reading. Wallman et al. Proposed that long-time close reading is a special form deprivation. It is considered that during close operation, the written illumination is worse than that outside the home, the books are mostly in black and white, most retinal cells have less response and are in an inhibitory state, and only macular foveal cells are sensitive. That is, during close operation, only the macular fovea of the retina can obtain sufficient visual stimulation, while most other parts of the retina can not obtain clear images, lack of sufficient stimulation and reduce cell activity. Over time, the ocular axis will grow, resulting in myopia. Peng Guangyuan and others found that the prevalence of myopia among young students is increasing from primary school to junior middle school to senior high school, which is mainly caused by the aggravation of learning tasks and the extension of learning time, especially the extension of close operation time, resulting in special form deprivation., 2. There are too few outdoor sports activities, and living in a narrow space is not conducive to visual development. Animal experiments have proved that small animals living in a narrow environment are prone to myopia. In addition, parsinen et al. Proved that people with myopia participated in less sports activities in adolescence, but there was no significant difference in this regard in adulthood. The specific reason is not clear. Seet et al. Also showed that too little outdoor activity was associated with myopia., 3. Night illumination. When the
eye is in a relaxed state, the parallel light passes through the ocular refractive system and focuses on the retina, which is called myopia. Myopia has increasingly become the focus of research, and its exact pathogenesis is not clear. Only epidemiological investigation shows that it may be related to a variety of environmental factors, so it is particularly important to prevent and reduce its occurrence.
lifestyle leads to myopia:
1. Wallman and others proposed that long-time close reading is a special form deprivation. It is considered that during close operation, the written illumination is worse than that outside the home, the books are mostly in black and white, most retinal cells have less response and are in an inhibitory state, and only macular foveal cells are sensitive. That is, during close operation, only the macular fovea of the retina can obtain sufficient visual stimulation, while most other parts of the retina can not obtain clear images, lack of sufficient stimulation and reduce cell activity. Over time, the ocular axis will grow, resulting in myopia. Peng Guangyuan and others found that the prevalence of myopia among young students is increasing from primary school to junior middle school to senior high school, mainly due to the aggravation of learning tasks and the extension of learning time, especially the extension of close operation time, resulting in special form deprivation.
2. There are too few outdoor sports activities. Living in a narrow space is not conducive to visual development. Animal experiments have proved that small animals living in a narrow environment are prone to myopia. In addition, parsinen et al. Proved that people with myopia participated in less sports activities in adolescence, but there was no significant difference in this regard in adulthood. The specific reason is not clear. Seet and other research results also show that too little outdoor activity is associated with myopia.
3. Night light
Quinn found that night light sleep is closely related to the occurrence of myopia. Animal experiments show that continuous light stimulation can lengthen the eyeball, and its mechanism is not clear. However, saw [18] found that the relevant research results were different and did not draw this conclusion. Whether night continuous light stimulation can cause myopia is still under debate, but it is a consensus that reading in dim light is easy to cause myopia.
4. Lack of sleep
recently, rose and others found that the formation of low-grade myopia has no obvious genetic relationship, but is closely related to sleep time. Studies have shown that the imbalance of the function of local sympathetic nerve and parasympathetic nerve is the pathological basis of myopia. Due to lack of sleep, it can cause systemic autonomic nerve dysfunction, and systemic autonomic nerve dysfunction will inevitably affect the function of local sympathetic nerve and parasympathetic nerve of the eye, resulting in disorder of ciliary muscle regulation and the formation of myopia.
some ways to prevent myopia:
breakfast
eggs 1 ~ 2 milk a cup, break the eggs and mix them well. After the milk (milk powder can also be mixed) is boiled, pour the eggs, roll up and stop the fire. Pay attention not to eat raw eggs, because raw eggs are not easy to be digested and absorbed by the human body. Don’t cook the eggs too old, because eating too much boiled protein food not only tastes bad and is not easy to digest and absorb, but also can cause abnormal calcium metabolism in the body and calcium deficiency. In addition, we should pay attention not to put sugar, because eating too much sugar will also cause imbalance of calcium metabolism and decrease of blood calcium. If you want something sweet, it’s better to put some honey. It shows that eggs and milk are nutritious products, rich in protein, fat, inorganic salts and vitamins. Inorganic salts are rich in calcium and phosphorus, vitamins A, B1, B2, etc. the protein contains all essential amino acids. These substances play a certain role in the nutrition of ocular muscles, sclera, retina, optic nerve and other tissues. Through nutrition, it can enhance the strength of ciliary muscle and the tenacity of sclera.
shredded Chinese wolfberry meat ingredients
100 grams of Chinese wolfberry, 300 grams of lean pig meat, 10 grams of bamboo shoots (or Magnolia slices), 100 grams of lard, and an appropriate amount of cooking seasoning: wash the lean pig meat and cut it into thin filaments of about 6 cm. Make the same for bamboo shoots and wash the Chinese wolfberry. When the oil is 70% hot, stir fry shredded pork and shredded bamboo shoots, add cooking wine, soy sauce, salt and monosodium glutamate, add medlar, stir fry a few times, and pour sesame oil. Description: Lycium barbarum can nourish liver and kidney, moisten lung and brighten eyes. Pork is rich in protein, which can nourish the body and make Qi and blood exuberant
