The World Health Organization (WHO) estimates that at least 35 million people worldwide require low vision care services for refractive errors. Among the refractive errors, myopia is the most common, and myopia is most common in adolescents. Myopia not only damages vision, leading to low vision, but can also cause blindness.June 6 is the National Eye Care Day, in the 11th “National Eye Care Day” is approaching, a reader’s article attracted our attention. In the article, a wear 44 years of glasses, “old myopia” “blue”, recounted his own early use of magnifying glasses eye experience and thus triggered a lot of associations and appeals. Is there a basis for this method? Prevention of myopia begins with learning to hold a pen In the prevention and treatment of pseudomyopia, there is a “fog vision therapy”. This is under the guidance of a visionary, reading and writing with a pair of glasses of about +1.50, can reduce the regulation of the jiezhuo muscle and the collection of extraocular muscles, so as to read books and newspapers. This method is now applied in some districts among elementary school children. This is the same reason that Comrade Little Blue unconsciously adds a magnifying glass in front of his eyes to read, which can reduce visual fatigue and prolong reading time. For people with low vision, specialty hospitals also use telescope-like vision aids to help improve reading skills. Text workers and people who often use computers, especially those with high myopia, can try Comrade Blue’s method. True myopia can be prevented but not cured The formation of myopia in young people for more reasons, but exclude congenital or hereditary factors, pseudomyopia is mainly in the preschool or elementary school stage to develop bad reading habits including lower pen, reading and writing distance is less than 30 centimeters, reading and writing for a long time caused by. If poor reading and writing postures are not corrected in time and appropriate treatment is provided under the guidance of a doctor, pseudomyopia can be transformed into true myopia over a period of time. True myopia is caused by over-regulation and long-term spasm of the Jejunal muscle, which turns the eyeball from a normal spherical shape to an ovoid shape, and the layers of the eyeball wall are thinned accordingly. Nowadays, there is no effective method, no matter it is an instrument or a drug, which can return the eyeball which has turned into an ovoid shape back to an orthorhombic sphere. Therefore, the myopia treatment instruments and drugs sold on the market are publicized with vague concepts and lack of scientific basis. However, true myopia can be prevented, the key is to actively treat pseudomyopia, blocking its development to true myopia. Surgical treatment should be cautious Excimer laser treatment of true myopia is a high-tech principle of treatment, with many advantages, has been widely known. Discussing from the optical principle, the surgery is accomplished by damaging a part of the normal corneal tissue, just like putting an invisible pair of myopic glasses on the patient, and it has no therapeutic effect on the myopic oval eye and the corresponding deformation changes of the fundus. Caution is needed because of possible complications. Font size, color, one can not be less The publishing industry to protect the eyesight of the nation from the perspective of scientific design layout, including teaching materials, newspapers and magazines, books, etc., the font size should not be too small, the color of the paper and the color of the text should be contrasting, for example, black and white contrast is greater, the eyes are not easy to fatigue. On the contrary, red and blue, gray and white, such as small contrast publications, reading under the light is particularly difficult for the elderly, children, high myopia and low vision people are not suitable. All printed materials, the text as large as possible, the distance between the lines can be reduced to give the reader a clear, relaxed and pleasant feeling.
