Wrong prevention methods, “manufacturing” myopia: “There are many myopia prevention methods are simply wrong, not in the ‘treatment’ of myopia, but in the ‘manufacturing ‘ myopia.” Chu Renyuan said, “The lag in scientific knowledge of myopia is an important reason why it is difficult to get timely prevention and correction of myopia in China’s youth.” China’s high incidence of myopia, and the following two factors are inextricably linked: on the one hand, the lack of professional myopia prevention and treatment personnel and myopia prevention and treatment of the unified management body, “optometrists do not know medicine, ophthalmologists do not know optometry, how can do a good job of myopia prevention and treatment”; on the other hand, too much commercial hype, many businessmen wildly speculate myopia The concept of prevention and treatment, only concerned about making money. “The methods they boast of not only do not play a role in the prevention and treatment of myopia, but also delay the ‘golden period’ of myopia prevention and treatment for young people, and even ‘cure’ false myopia into real myopia, low myopia ‘cure’ into high myopia.” Chu Renyuan said. “In some places, some people claim to use tui na, acupuncture and other means can treat adolescent myopia.” Chu Renyuan said, many people who have used these methods will find that its short-term effect is very obvious, vision improve quickly, but a long time vision and then decline, “this is because these methods are actually like to the eyes injected ‘stimulant’, although there are short-term results, but can not fundamentally treat myopia. ” Now many commercial advertising that most of the youth myopia for pseudomyopia, can be treated, but Chu Renyuan said: “pseudomyopia is treatable, but the epidemiological survey found that pseudomyopia in the youth myopia only 2.4%, that is, more than 97% of the youth myopia can not be completely cured with physical therapy”. Improper pencil grip posture, resulting in myopia: in the interview, Chu Renyuan walked to the reporter is buried in front of the record looked at the reporter’s pencil grip posture, and then told the reporter: “Your pencil grip posture is not right, grip the pen should be the right thumb and middle finger touch, and you are now the thumb and index finger straight touch.” Chu Renyuan said, “the biggest cause of myopia does not lie in the traditional perceived eyes too close to the book, but the wrong pencil grip posture.” Chu Renyuan said, not only the onset of myopia and the use of different pencil grip posture, refractive error and deepening of the pencil grip posture is also related. The traditional view is that the key points of the correct pen grip posture is the eyes from the book 1 foot, chest from the edge of the table 1 fist width, grip the pen from the tip of the pen 2cm, but the promotion of this standard posture has not really curbed the growing incidence of myopia. A survey was conducted on the pencil grip of 300 orthoptic and 300 myopic students and found that orthoptic children were more likely to adopt a posture where the thumb and index finger did not touch each other, while myopic students preferred to pinch or cross their thumb and index finger, and the deeper the degree, the higher the rate of adopting the wrong posture The reason is that when a child maintains a standard sitting posture, if the thumb and index finger of the pencil grip are pinched or crossed, the fingers will block the view, making it difficult for him to see the The reason is that when a child maintains a standard sitting posture, if the thumb and index finger are pinched or crossed, the fingers will block the view, making it difficult for the child to see the pen tip and forcing him to lower his head or tilt his head to the left, thus closing the distance between the eyes and the book, increasing the onset of myopia and accelerating its development. On the contrary, if the thumb and forefinger do not touch each other posture, not only writing force more scientific, but also will not block the normal vision of the gaze, so as to ensure that children use the eyes of science. What is the most effective way to prevent myopia in teenagers? There are so many myopia patients, what are the best prevention and treatment methods? There is no cure for myopia in the world, and the main methods to correct myopia are: frames, contact lenses and surgery. The method to control myopia that is now commonly clinically recognized is modern keratoplasty, especially for adolescents under the age of 18 who cannot undergo excimer surgery. “Corneal shaping lenses are so effective in controlling myopia that both the State Food and Drug Administration (SFDA) and the U.S. FDA have approved the clinical use of corneal shaping lenses, and these approvals were made after rigorous clinical trial validation. Research at the Center for Optometric Research at Peking University School of Medicine showed that after three years of wearing keratoplasty lenses, the average annual myopia increased by 8 degrees, while the average annual myopia increased by 67 degrees with frame lenses.” Chu Renyuan said, “This technology, although from the United States, but there are already domestic according to the characteristics of the Chinese eye independent research and development of corneal plastic lens, which is undoubtedly a blessing to our country’s youth myopia patients.” Although the effect of wearing keratoplasty lenses is not age-specific, it is better for adolescents who are adaptable, have soft eyes and are in a period of rapid myopia growth, and can effectively control the deepening of myopia. ”Keratomileusis is a medical technology that requires qualified physicians, optometrists, qualified lenses and qualified users to be both safe and effective. The technology itself is very safe, if you want to wear keratoplasty lenses, you must choose a professional eye hospital or a qualified institution, by a professionally trained ophthalmologist or optometrist for fitting”.
