Abstract: after myopia, the parallel light passes through the refraction of the human eye, and the imaging can only reach the retina, and the imaging of the retina becomes a fuzzy spot. However, the ability of photoreceptor cells in each person’s retina to analyze this blurred spot is different. There will be the same degree of myopia, but different naked vision.
parents have two misunderstandings about children’s myopia
the more they wear glasses, the deeper they wear
many people insist on not wearing glasses after myopia, and think that once they wear them, they can’t live without them, and will aggravate myopia. However, the opposite is true.
long time close eye use is an important factor leading to myopia. Wearing appropriate corrective glasses can alleviate over adjustment and prevent the deepening of myopia to a certain extent. If the degree of myopia is high but do not wear glasses, it will habitually squint and frown, which is more likely to cause visual fatigue and accelerate the development of myopia.
teenagers and children in the stage of eye growth and development, if they are short-sighted, then the degree is likely to increase year by year; It has nothing to do with wearing glasses. On the contrary, some glasses can both correct vision and delay the deepening of degree.
after wearing glasses, the naked eye vision is getting worse and worse.
first of all, we should understand that the naked eye vision cannot be equated with the degree of myopia. Even if two children with the same degree of myopia may have different naked eye vision. After
myopia, the parallel light passes through the refraction of the human eye, and the imaging can only reach the retina, and the imaging of the retina becomes a fuzzy spot. However, the ability of photoreceptor cells in each person’s retina to analyze this blurred spot is different. There will be the same degree of myopia, but different naked vision.
the reason why naked eye vision is getting worse and worse after wearing glasses is that naked eye vision has not decreased, but the brain is unwilling to adapt. Because before wearing frame glasses, the child’s brain will be forced to deal with the blurred image caused by myopia. When the child wears frame glasses for vision correction, the brain is “unwilling” to recognize the blurred image after taking off the glasses, which is the reason for the “deterioration” of naked eye vision. The vision of
children is affected by many factors, such as diopter, retinal analysis ability, brain recognition ability and so on. After myopia, the naked vision will not get worse and worse because of wearing glasses. On the contrary, if the child is not checked in time and corrected scientifically after myopia, it will also increase the child’s visual fatigue and may further deepen the degree of myopia.
many parents go astray because they don’t want to match their children with glasses. They are attracted by the “secret recipe” and “massage instrument” on the Internet, which are completely inconsistent with scientific common sense, but this love is in the wrong direction. If the child has vision problems, please take the child for optometry in a regular hospital. If glasses are needed, they should be matched in time.
