The following two methods can be used: 1, cloud method: first let the patient wear a higher degree convex lens, preferably with 300 degrees of presbyopia, so that the patient can not see clearly, especially in the cloud, for 20 to 30 minutes, the purpose is to relieve the tension of the ciliary muscle. 2, dilated pupil method: Use ciliary muscle anesthetics, such as atropine or tropicamide ophthalmic solution to dot the eyes to anesthetize the ciliary muscle and release the regulatory spasm. Before testing with the above methods, you should find out the distance vision and optometry, if the child’s vision has progressed or returned to normal before the test, for example, the visual acuity of both eyes before the test is 0,5, after the test is 1,0, then it can be diagnosed as pseudomyopia. Or the optometry reveals a significant reduction or disappearance of myopia.
