With the change of modern lifestyle and learning style, the incidence of myopia in children is surging, and there is a clear trend of low age, many kindergarten children have already put on myopia glasses. Many parents feel unbelievable about their children’s premature myopia, in the face of society, such as acupuncture, massage, ear patches, training, drugs and other methods of treatment of myopia, some parents simply try all kinds of myopia therapy for their children, the result is not less money, but myopia is not effectively controlled and improved. So, how can we achieve scientific prevention and treatment of myopia? To prevent myopia, eye habits and outdoor activities are the key The main factors of myopia are genetics and environment. However, genetic factors only increase the probability of myopia in the next generation. Many children who are nearsighted have parents who are not nearsighted, and this has to do with the environment in which they use their eyes. The habit of prolonged close eye use is a major cause of myopia. We know that myopia is mainly due to the growth of the eye axis (diameter of the eye) or the increased refractive power of the eye. Excessive eye use requires excessive regulation, resulting in a continuous state of regulatory tension, which causes a momentary reduction in vision and the formation of pseudomyopia, which can be improved or completely restored after rest or the use of ciliary muscle paralyzing agents; too close to the eye, the extraocular muscles also exert pressure on the eye, and the scleral tissue of the eye wall gradually extends under the long-term mechanical pressure of the extraocular muscles, and the eye axis (anterior and posterior diameter) elongates, forming true myopia. Studies have shown that reading time of 2 hours and reading distance of 825px are important points for myopia to occur. Children’s eyes are in the developmental stage and are easily changed by the external environment. Excessive eye use and poor eye habits can very easily contribute to the occurrence and development of myopia, and myopia is important to prevent, so parents should help their children to develop good eye habits. More and more studies show that too little time outdoors is also a cause of myopia. Outdoor activities not only relax and rest the eyes, but sunlight increases the secretion of dopamine, which limits the rapid growth of the eye axis and the progression of myopia, so parents should increase their children’s time outdoors. Myopia diagnosis for children and adolescents requires dilated eye examinations. Once a child’s vision is found to be declining, parents should promptly take the child to a regular medical institution for a professional diagnosis. Because the muscles that focus the eyes of children (ciliary muscles) tend to be tense, they need to go to the hospital and use dilating medication (ciliary muscle paralyzing agent) to make the ciliary muscles completely relaxed before they can be diagnosed with myopia. There are both long-acting and short-acting dilating medications, which are often referred to as slow-acting and fast-acting dilating agents, generally long-acting dilating agents (atropine) for younger children and fast-acting dilating agents (tropicamide, cycloplegia) for older ones. Some parents report that their children’s eyesight has improved through “vision training, acupuncture, and massage therapy,” but some parents report that their children’s eyesight has improved through “vision training, acupuncture, and massage therapy.
Some parents have reported that their children’s vision has improved through “vision training, acupuncture, and massage therapy”, but their myopia has increased instead of decreasing at the hospital. First of all, naked eye vision is a very one-sided indicator, the examination method, environment, different examiners, the examination results may not be the same, the examination of vision requires the child not to frown, not to squint, not to tilt the head, and these requirements are often ignored by the examiner, so the naked eye vision can not accurately reflect the true situation of myopia. Secondly, through some training, children repeatedly identify the visual markers without glasses, which temporarily improves the brain’s ability to recognize blurred images, and during the vision check, although the eyes still see things blurred, the brain can recognize them, creating the illusion that the eyes have become better. If you want to identify whether your child’s myopia has improved, you can confirm the diagnosis by going to the hospital for an optometry and an eye axis examination. Since the increase in myopia in children is essentially due to the growth of the eye axis, and this “organ growth” is irreversible in normal people, it is the same as a taller person does not become shorter, so true myopia is essentially incurable. The actual myopia will not be deepened by wearing glasses Many parents believe that wearing glasses will deepen myopia and make the eyes distorted. This is one of the misconceptions parents have about myopia prescription glasses. In fact, myopic people wear the right glasses, eye adjustment and convergence function to restore the normal coordination of the relationship, so myopia will be relatively stable. Therefore, wearing a suitable pair of glasses and paying attention to eye hygiene can slow down and control the deepening of myopia to a greater extent. If you don’t wear glasses, your eyes are in a state of frequent adjustment, which can easily produce fatigue and further myopia, and squinting for a long time without glasses can easily lead to astigmatism. Therefore, after the child is diagnosed with true myopia, he or she should go to a regular medical dispensing facility to have high-quality myopia glasses to correct it. After the prescription, low-degree (200 degrees or less) myopia need to be far-sighted, above 200 degrees need to wear glasses for a long time. Keratomileusis can effectively control myopia Keratomileusis is a new myopia correction and myopia control technology that has been clinically recognized as having better results. It is a special rigid corneal contact lens designed according to the myopic user’s corneal geometry and refractive error. The lenses are made of highly breathable materials and are worn by the user for 8 to 10 hours a day, with the rest of the day when the eyes are not myopic or in a reduced myopic state, and no glasses are needed during the day if the lenses are worn at night. Corneal shaping is suitable for people with low to moderate myopia within 600 degrees, and can effectively curb the rapid deepening of myopia in youth. It is important to note that keratoplasty is a strictly medical practice, as it is in direct contact with the cornea and there is a risk of corneal infection if not properly fitted or cared for, and must be performed in a standardized eye care facility with strict care procedures and follow-up visits under the guidance of a physician to ensure healthy and safe fitting.
For some people who are not suitable for corneal wear, it is important to follow up with the doctor. For some patients who are not suitable for wearing keratoplasty lenses (such as high myopia, high astigmatism, etc.) can choose RGP to slow down the process of myopia, RGP is also a hard contact lens made of highly breathable material, which is worn during the day. The key is for schools, families and doctors to work closely together to improve children’s eye environment and help them develop good eye habits. If your child is nearsighted, he or she should go to the hospital in time and choose a reasonable means of correction according to the doctor’s advice to achieve the best control effect.
