The health of adolescents' eyesight requires the joint protection of families, schools, and society. In recent years, the popularity of electronic products has also led to a trend of low age myopia. The increase in the rate of myopia among children and adolescents has caused more and more anxiety among parents of students. Faced with nearsightedness, parents sometimes try to be anxious, but they seek help from nothing and are unable to follow suit. The editor will give you some examples of misconceptions, please be careful! Myth 1: After children go to school, they only need to have their eyesight checked. Many parents believe that after children go to primary school, they need to have their eyesight checked because they use more eyes. In fact, after the age of 3, most children can cooperate with a visual acuity test after learning to recognize a visual acuity chart, and can undergo preliminary visual acuity testing. It is recommended to conduct visual acuity screening every three months to six months. Schools or parents can purchase a standard visual acuity chart and hang it on the wall at a distance of 5 meters for the child to recognize. In daily life, parents should be vigilant if they find their children squinting, squinting, rubbing their eyes, or watching TV and books very closely. There may be a problem with their eyesight. Parents should promptly bring their children to a regular medical institution to establish refractive development records for their children. The starting time of the examination should preferably be no later than 3 years old, which is helpful for early detection of eye diseases and refractive abnormalities such as myopia, astigmatism, high hyperopia, strabismus, amblyopia, etc., screening out "dangerous molecules" of myopia, timely preventing and controlling the progress of myopia, and early intervention. Myth 2: Low degree=Pseudomyopia Many parents often blurt out when they hear about a child's myopia: "Is it fake or true?" Many people believe that a small child with low degree is pseudomyopia and is reversible. In fact, pseudomyopia refers to a temporary decrease in visual acuity caused by excessive use of the eye at close range and tight adjustment of the ciliary muscles of the eye. After rest or application of ciliary muscle paralysis agent eye drops, visual acuity can return to normal. However, in routine hospital examinations, if the degree of myopia is detected, it is no longer pseudomyopia. Even if the child is young and the degree is small, it is no longer pseudomyopia that regulates tension. Therefore, when a child has decreased vision, it is very necessary to go to a regular hospital for mydriasis and optometry in a timely manner. Pseudomyopia can be ruled out through mydriasis. For most nearsighted children, choosing a fast mydriasis optometry that can recover automatically within 4-6 hours is sufficient. Myth 3: Wearing glasses for viewing from afar, whether wearing glasses for viewing near or not, and wearing glasses (with appropriate degrees) for nearsighted eyes need to be adjusted when viewing close. By adjusting and changing the focal length of the eyes, the focus of light can be shifted from a distance to the close object we are looking at, in order to see clearly. In myopia, without wearing glasses, the focal length of the eye is at close range, and the eye can be lazy without adjustment. However, if the eye is lazy for a long time, its adjustment function will decrease, and it will also affect the ability of the eye to converge. Under normal conditions, when viewed closely, the eyes will align inwardly to a certain extent, which is called the cohesive function. Except that doctors may not wear glasses if they have special instructions, it is recommended that children with myopia wear glasses when looking far and near. Myth 4: The more you wear glasses, the faster your myopia deepens. True myopia detected after mydriasis is irreversible. Most nearsightedness is caused by the growth of the ocular axis, which refers to the distance between the anterior surface of the cornea and the fundus retina, which enters the light path of the eye
