High myopia, also known as pathological, progressive and malignant myopia, has refractive error equal to or exceeding C6.00D and progressive prolongation of the eye axis. The fundus lesions include choroidal and retinal pigment epithelial atrophy, macula crack-like changes, hemorrhage, neovascularization, and can be complicated by cataract, glaucoma, retinal detachment, etc., so that the retinal function is obviously impaired, which is one of the important causes of blindness. Therefore, the following aspects should be noted in daily life: 1. Be sure to wear appropriate glasses. You must undergo a comprehensive examination by an ophthalmologist at a regular hospital before making a formal optometry, so as not to cause a vicious circle and aggravate the development of myopia. 2, avoid strenuous, impact head sports, eye trauma, etc. to prevent retinal detachment. 3, less spicy food, avoid smoking and alcohol to prevent repeated bleeding in the macula of the eye. 4.Carefully choose your job, avoid heavy physical labor and work that uses too much eye. If you do close reading, writing or fine work for a long time, the muscles inside and outside the eye need to be adjusted constantly, which not only makes the wall of the eye compressed, making the eye longer and myopia aggravated, but also makes the small blood vessels of the macula choroid stretched and cause rupture, resulting in macular hemorrhage, which makes the vision more reduced. 5, regular eye examination. Pay attention to the length of the eye axis, vitreous, retina and macula, and pay attention to whether there are dry fissures and retinal detachment signs around the retina. 6, myopia patients generally lack chromium and zinc, myopia patients should eat more food containing more zinc. Foods such as soybeans, almonds, nori, kelp, mutton, yellow fish, milk powder, tea, meat, beef and liver contain more zinc and chromium and can be increased in moderation.
