Four methods can delay the progression of myopia

Abstract: in recent years, the myopia rate of students after the age of eight or nine has increased rapidly, and the development of diopter also has obvious regularity. According to this situation, it is suggested to strengthen visual acuity monitoring when children are eight or nine years old, and timely and scientifically wear low-intensity convex lenses for intervention before the symptoms of pseudomyopia appear, which can effectively prevent myopia., True myopia cannot be cured. We can only try to control the progress of myopia. Because teenagers are in the stage of growth and development, which is the period when they read more books, have more homework and are busy with homework. If they spend a long time watching TV, computers and playing games, have less outdoor activities, incorrect reading and writing posture and insufficient indoor lighting, the degree of myopia becomes difficult to control and easy to deepen rapidly. Statistics also show that myopia develops at a high speed between the ages of 12 and 18. Over the years, how to effectively prevent and control the progress of juvenile myopia has been a subject that international optometry experts have been trying to study. Although no breakthrough has been made, some methods have also been found to control some myopia., In addition to establishing scientific eye habits, the first prevention and control measures that have been clear at present is the prevention and treatment of myopia with low convex lens, which is commonly known as “reading glasses” can prevent myopia. China’s myopia prevention and treatment expert group began to advocate this method in 1998, but it has not been popularized in a large area because most people do not know when to wear it and it is easy to cause visual fatigue, affect the development of visual function and cause exophoria. In recent years, the myopia rate of students after the age of eight or nine has increased rapidly, and the development of diopter also has obvious regularity. According to this situation, it is suggested to strengthen visual acuity monitoring when children are eight or nine years old, and timely and scientifically wear low-intensity convex lenses for intervention before the symptoms of pseudomyopia appear, which can effectively prevent myopia., Second, wearing progressive multifocal glasses can slow down the rapid development of myopia by reducing or interfering with eye adjustment. This technology is a new progress in myopia control in the world, and it has just started in China. This method is only effective for simple myopia. Strict indication screening must be carried out before wearing. The initial age of myopia is 10 years old or above, and the diopter of both eyes is more than 175 degrees. At the same time, it should be worn scientifically under the guidance of ophthalmologists, and a comprehensive reexamination must be done once every three months., Third, rigid breathable contact lenses (RGP) customized according to individual corneal morphology can control the progression of myopia. RGP is close to the cornea, and its corrected visual acuity is closer to that of normal eyes. Because the lens is hard, it can exert a certain compressive effect on the cornea, flatten the cornea, reduce the corneal diopter and corneal astigmatism, control the growth of ocular axis, and slow down the progress of diopter. This method is especially suitable for teenagers with rapid progress of keratoconus and myopia, but the disadvantages are that they need daily cleaning and nursing, and there is a sense of foreign body in their eyes., The fourth is the day throwing soft contact lens, which is the latest research based on RGP. After scanning the patient’s corneal morphology, the manufacturer will make contact lenses completely consistent with the patient’s cornea to ensure the best visual quality of the patient, which is also the biggest difference from ordinary soft contact lenses. The participating adolescent patients were rechecked every three months, during which they still had to scan the corneal morphology for many times to ensure that the glasses fully conformed to the growth and development of the cornea., In addition, experts remind parents that due to the side effects of drugs, they usually do not advocate drug treatment of true myopia. At present, various eye care and health products sold on the market may alleviate visual fatigue, but they cannot be determined to have the effect of myopia treatment because of the lack of authoritative clinical evidence.,

true myopia can not be cured. We can only try to control the progression of myopia. Because teenagers are in the stage of growth and development, which is the period when they read more books, have more homework and are busy with homework.
