Six misunderstandings to be vigilant in the prevention and treatment of myopia

Abstract: 12-year-old and 13-year-old children are at the peak of growth, with great learning pressure and an increasing trend of eyeballs. Myopia deepens and increases by 100 degrees every year. Parents should actively prevent it in early childhood. It is recommended that children over 3 years old should have an eye health examination every year.

nowadays, myopia prevention and treatment has become a topic of comprehensive concern, and there are many statements about myopia prevention and treatment on the Internet. Most of these statements deviate from the track of rational and scientific prevention and treatment, and seriously mislead netizens. Experts summed up six misunderstandings about the prevention and treatment of myopia to remind netizens to correctly prevent and treat myopia and take care of eye health. Misunderstanding 1 of

and

: vision loss must be myopia. Doctors of

and

pointed out that vision loss is not necessarily caused by myopia. Vision loss is mainly related to two problems: on the one hand, eye diseases may lead to vision loss, such as macular disease, glaucoma and eye inflammation; On the other hand, ametropia can also cause vision loss, such as myopia, astigmatism and hyperopia. Therefore, experts remind parents that if they find their children’s abnormal vision, squint and always rub their eyes, they’d better go to a regular hospital for ophthalmic examination, and the doctor will judge whether the vision loss caused by myopia, and then treat them symptomatically.

misunderstanding 2: once myopia occurs, it is irreversible.

myopia is mainly divided into true myopia and false myopia, in which true myopia is irreversible and false myopia is reversible.

according to the principle of myopia, true myopia is mainly due to the increase of the axis of the eye, while false myopia is to regulate the tension of the ciliary muscle of the eye. Huang Yuanzhou optometrist said: “pseudomyopia can be relieved by eye drops (low concentration atropine) to relieve the tense ciliary muscles, or by eye relaxation or eye health training for a period of time, so as to restore vision.” Pseudomyopia generally occurs in front of true myopia, which is a signal of myopia. If you don’t pay attention, it will soon become true myopia. In particular, children aged 12 and 13 of

and

are at the peak of growth, with great learning pressure. Their eyeballs also tend to grow, and myopia deepens, with an annual increase of 100 degrees. It is common. Parents should actively prevent it in early childhood. It is recommended that children over 3 years old should have an eye health examination every year. Misunderstanding 3 of

and

: myopia is not terrible, and it can be completely cured. True myopia of

and

cannot be cured. Pseudomyopia can be cured by drug treatment and paying more attention to outdoor activities. True myopia is caused by the lengthening of the length of the eye. Once the eye axis grows, it can not be shortened. On the contrary, it will grow longer and longer. Therefore, true myopia is incurable.

although true myopia can not be completely cured, it can be controlled. First of all, it is best to pay attention to controlling the degree of myopia in adolescence. Research shows that the most effective way to control myopia is to increase outdoor activities, increase the outdoor activity time by 40 minutes per day, and reduce the incidence rate of myopia in 3 years. Secondly, use your eyes reasonably, reduce close eye use, keep the distance between your eyes and the desktop when reading and writing, don’t use your eyes too long, and rest for 10 minutes every 40 minutes. Finally, do regular eye health examination to understand the child’s eye refractive status in time. Misunderstanding 4 of

and

: children had better not dilate their pupils during optometry, Because mydriasis has side effects,

and

mydriasis (ciliary muscle paralysis) optometry is one of the important optometry methods to check the refractive state of children’s eyes, but many parents are worried about side effects. According to Huang Yuanzhou optometrist, mydriatic optometry is to drop the special eyedrops of ciliary muscle paralysis into the eyes to completely paralyze the ciliary muscle of the eyes and achieve the most relaxed state, and then optometry, because the eye with mydriatic agent is difficult To make the optometry more accurate; If there is no mydriasis, children with myopia will have optometry with adjustment, which often leads to higher diopter than the actual diopter; Children with mild hyperopia will also be misdiagnosed as myopia.

misunderstanding 5: wearing glasses after myopia will cause eye protrusion

many people are afraid to wear glasses because they are worried that wearing glasses after myopia will cause eye protrusion. In fact, this practice is wrong. Not wearing glasses because of myopia will cause unclear distant objects, which will inevitably lead to eye fatigue. The result can only promote the degree to deepen day by day. Because the eyeball of teenagers is still in the development stage, regulatory myopia is very easy to develop into axial myopia. In particular, compound myopia astigmatism is often easy to cause ametropic amblyopia if you don’t wear glasses in time. Therefore, experts suggest that if myopia occurs, you must go to the hospital ophthalmology or professional institutions for examination, and choose to wear appropriate frame glasses or contact lenses. Misunderstanding 6 of

and

: it doesn’t matter if the eyes have astigmatism. There is no need to correct it. Doctors of

and

said that most astigmatism needs to be corrected. Like myopia, astigmatism is also divided into low, medium and high. Low astigmatism is within 100 degrees, moderate astigmatism is within 125 degrees – 225 degrees, and high astigmatism is above 250 degrees. If low-grade and physiological astigmatism does not affect your vision, you can not wear glasses, but if your eyes have adverse symptoms, such as always rubbing your eyes or tilting your head, you can consider wearing glasses as appropriate; Moderate and high astigmatism need to be corrected with glasses. If it is not corrected, it is prone to visual fatigue and visual acuity will be affected. Usually, when matching frame glasses, if astigmatism is detected, the doctor will generally give an appropriate degree of correction.
