Medical research generally believes that myopia is related to genetic factors, improper use of eyes and dietary preferences. In recent years, some researchers have found that myopia is also related to the lack of zinc, calcium, phosphorus and other elements and amino acids in the patient's body. According to traditional Chinese medicine, the occurrence of myopia is due to insufficient liver and kidney function and deficiency of blood and qi. Therefore, for myopia, besides paying attention to hygiene and overcoming picky eating habits, it can also be adjusted through diet, by tonifying liver and kidney qi and blood to prevent and treat myopia. Excessive consumption of sweets can lead to a large amount of alkaline substances and vitamin B1 being consumed, which may cause a decrease in children's vision or even lead to poor vision development. Excessive sugar can also reduce the storage of trace element chromium in the body, leading to a decline in vision. Vitamin A can maintain the integrity of human cells and participate in the synthesis of substances that enhance night vision ability. Vitamin A mainly comes from various animal livers, milk and egg products. Plant-based foods such as spinach, carrots, peas, sweet potatoes, and peppers contain large amounts of beta-carotene, which can be converted into vitamin A in the body. Regularly eating these foods is beneficial for eye health. If you have myopia, 1. Wearing corrective glasses is currently recognized worldwide as the most appropriate, effective, and safe treatment method. Before getting glasses, pupil dilation examination should be conducted to rule out pseudo-myopia and determine the actual degree of refractive error. Because teenagers usually use their eyes a lot, it is especially important to pay attention to eye hygiene and improve the learning environment. 2. For teenage myopia, if there is no special need, it is best to wear ordinary framed glasses, which are both economical and practical. If necessary for work, contact lenses can also be worn. After long-term observation, alternating use of contact lenses and framed glasses is good. When wearing contact lenses, it is important to select them reasonably, wear and remove them correctly, strictly clean and disinfect them, and replace the contact lens in time. Do not wait until the lens is damaged before replacing it, otherwise it may cause damage to the eyes.
