The most common in the summer and winter is refractive error or amblyopia of children, now on myopia briefly: 1, look too close is currently the main reason for the number of myopic patients. Some research statistics show that the percentage of myopia in Europe and the United States is about 40%, while the East Asian population is much higher than this, about 50%, mainly related to the cultural background of the East Asian population, the task of learning is relatively heavy, see too much. Therefore, for myopic patients, look less near, cell phone TV computer as little as possible, do homework no way, then write 40 minutes of homework, put on glasses to look away for 5 minutes to rest. 2. For patients whose astigmatism suggests the presence of myopia, the doctor recommends glasses must be worn. The indicator of wearing glasses: bare eye vision is less than 0.8. wearing glasses is the first method of myopia treatment. For myopic patients, seeing near is clear, but seeing far is not. Only when the patient can see far clearly with glasses can the therapeutic effect of glasses be achieved and the ciliary muscle of the eye be relaxed, slowing down the development of myopia. From my own point of view, it is recommended that patients wear glasses all the time, in addition to sleep not wear, other than wear. 3, you can also give your child some eye drops to delay myopia, such as: compound elimination of scopolamine eye solution, compound urinary vitamin eye solution, nearsightedness music eye solution, etc. 4, for children who wear glasses every six months in the regular hospital review. Because myopia grows with age, it is important to replace glasses in a timely manner. Indicators for wearing glasses with vision lower than 0.8, or wearing glasses for a long time with discomfort, it is necessary to re-dilate the pupil for optometry.
