China’s population is large, and young students are a high incidence of myopia. Because opticians optometry and professional ethics vary, certain systems are not yet sound enough and other reasons, looking at the current situation of our youth optometry, there are many irregularities and unscientific aspects, so how to get out of these misconceptions? Myth #1: The child’s poor eyesight is suffering from myopia. Some parents once found that the child’s poor vision (such as can not see the blackboard), it is arbitrarily that the child is suffering from myopia. In fact, there are many eye diseases that affect children’s vision, in addition to myopia, there are congenital eye lesions, hyperopia, astigmatism, amblyopia, etc. Parents should take their children to a professional ophthalmologist first when they find their children’s poor eyesight, and then carry out targeted treatment, otherwise it will not only be time-consuming and costly, but also delay the treatment of children’s eye diseases. Myth #2: Astigmatism is harmful to your child’s eyes. Because astigmatism is the gold standard for distinguishing true myopia from pseudomyopia, and to understand the true refractive state of a child, doctors routinely perform astigmatism on youngsters under 14 years of age. Some parents believe that dilated pupils are harmful to their children’s eyes, so for the sake of convenience, they will fit their children with glasses without dilating their pupils, which makes it easier to treat pseudomyopia and some mild to moderate hyperopia as true myopia. Of course, blurred vision and photophobia will occur for a short time after pupil dilatation, but will gradually improve after a few hours to a few days (the length of time depends on the medication used). However, those with high eye pressure, shallow anterior chamber and a family history of glaucoma should not have their pupils dilated. Myth 3: Don’t wear myopia glasses, myopia deepens faster after wearing glasses. Due to the excessive use of close eyes by teenagers and the refractive development of the human eye, myopia in teenagers is likely to deepen, but this is not directly related to whether or not to wear glasses. On the contrary, reasonable optical correction of myopia can help improve visual acuity, control myopia, improve quality of life, and contribute to normal physical and mental development. For example, some children often squint and squint due to myopia; some children can’t see well until they get glasses, and then they know that they are nearsighted by four or five hundred degrees; some children’s academic performance is affected by myopia. What is the best time to get glasses? It is generally believed that true myopia of 75 to 100 degrees or more, or affect learning, should be with glasses. The first thing you need to do is to get a good idea of what you’re doing. There is a significant difference between pseudomyopia and true myopia. Pseudomyopia is a temporary spasm of the ciliary muscle that can be relieved on its own, without the need for glasses; while true myopia is often accompanied by a lengthening of the eye axis, there is no recognized effective cure, and requires correction with glasses. Myopia is not related to the number of degrees. Some children have pseudomyopia of more than 500 degrees, while others may only have 50 degrees of true myopia. Therefore, students must choose a professional ophthalmologist for a detailed eye examination and receive standardized optometry in order to ensure that their eyes are protected from further damage caused by unqualified glasses.
