scientists believe that children and adolescents have poor eating habits, and the lack of some nutritional elements in the body is easy to induce myopia. These nutritional elements include protein, vitamin A, vitamin B, vitamin D, calcium, chromium, etc. Taurine is the highest content amino acid in the retina. It plays an important role in maintaining the structure and function of the retina. It helps to promote eye nutrition, alleviate eye fatigue and enhance eye resistance. Vitamin B6 participates in the synthesis and metabolism of taurine in vivo, helps to eliminate eye fatigue, enhance the activities of corneal and retinal cells, and promote the repair of inflammatory injury. Calcium and chromium can directly affect the body’s regulation of intraocular fluid pressure. Abnormal intraocular pressure is a factor in the formation of myopia. Vitamin A and vitamin D deficiency can affect the body’s absorption of calcium and chromium.
