”Nearsightedness is a sensitive topic for many parents, but there is no way to stop the low age of myopia. Especially with the popularity of cell phones, tablets and other electronic devices in life, the age of children wearing glasses is getting younger and younger. The trend of low age of myopia in children is becoming more and more obvious, and there are few children who suffer from true myopia at the age of 8 or 9 and need glasses. Preventing myopia is not only about watching less TV, but also about having a certain amount of outdoor activities. It is recommended that parents establish a refractive profile for their children, which will allow for timely targeted intervention for children at risk for myopia. ”iPad early education”, early brewing true myopia Recently, a news story will be myopia low age problem again turned out. A 5-year-old girl was tested for myopia – 100 degrees in her left eye and 50 degrees in her right eye. The father blamed the mother for always showing the iPad to the child, while the mother complained, “I just used it to show her early education films, how could I have known this would happen!” . There are many similar cases in clinical practice. Whether for educational purposes or as a “coaxing tool”, children’s misuse of computers, cell phones, TV and other electronic devices, the ophthalmologists “abhor”! Tablet computers and cell phones and other electronic products, not only the screen is small, bright, its rich content and information is also easy to prompt children to use a long time, close. This is likely to cause a decline in children’s eye regulation ability, too much use will also lead to children’s eyes dry, eye fatigue and other problems. When these bad eye habits cause the child’s eye axis to develop too quickly, it will begin to consume the child’s “farsightedness reserve”, once the farsightedness reserve is consumed in advance, it will cause myopia, and even the possibility of high myopia will also increase. “The youngest patient with dry eye seen in the hospital clinic is only 3 years old, and when parents are asked, they have been playing with their children’s cell phones since they were one year old. Nowadays, young parents themselves play with cell phones without restraint, and save time with their children, so it is difficult not to be myopic! The decline in farsightedness reserve is an early sign of myopia in children. Instead of mending the fold, it is better to prevent and detect it early. The decline in farsightedness reserve is an early sign of myopia in children. What is this “farsighted reserve”? In general, the eyes of infants, toddlers, and preschoolers are in a hyperopic state, which gradually normalizes with growth and development and basically reaches normal at the age of 7-10. The length of the eye axis is the main cause of vision, and the eye axis of preschool children is normally short, so there is no problem of “myopia”. However, when poor eye habits cause the eye axis to develop too quickly, and the eye axis “crosses the line” early and continues to grow, “myopia” will occur. For preschoolers who are not nearsighted, examining the farsightedness reserve can help prevent myopia by detecting the presence of myopia and intervening in a timely manner. This is usually done by “dilating” the pupil to help the child’s ciliary muscle relax completely, and then detecting the exact refractive error of the child and evaluating the child’s refractive status. The normal hyperopic reserve at different ages is +2.10 to +2.50 for 4 to 5 year olds, +1.75 to +2.00 for 6 to 7 year olds, and +1.50 for 8 year olds. 3 hours of outdoor activities can prevent and stop the progression of myopia. myopia is a concern, what should parents do?. The best way to help your child’s vision is to get more exercise outdoors. Some foreign research experiments have shown that children who spend three hours a day outdoors develop myopia or myopia progresses at a much lower rate than children who spend one hour outdoors. “Nowadays, children stay indoors more often, either playing or doing homework, which is undoubtedly one of the reasons for the low age of myopia.” . The theory that outdoor activity is good for vision health has long been in textbooks, but as the number of myopia has climbed worldwide in recent years, more and more studies and experimental observations have corroborated this theory Outdoor activity not only provides more exposure to sunlight, which promotes the secretion of dopamine, which blocks the growth of the eye axis and reduces the risk of excessive eye axis development; in addition, ultraviolet light also increases the synthesis of vitamin D in the body that hardens the sclera, which is equally helpful in slowing down the growth of the eye axis. In addition, a wider field of vision is also beneficial for the development of the eye. When your child is 3 years old, get a refraction profile. A child’s eye health, visual development, and vision are closely related to the health of the mother during pregnancy, at birth, and the growth and development of the individual after birth. The onset and development of myopia is not only related to eye habits and family genetics, but also closely linked to their growth and development rate, so caring for your child’s eye health issues should start at an early age. It is recommended that children over the age of 3 can visit our myopia center to establish a refractive development file to record the refractive development process of children in a planned and dynamic manner. This is mainly for children mainly 3 to 12 years old and adolescents under 18 years old. By performing 1 refractive examination every 6 months. By archiving the results of each eye screening and hospital visit, not only can refractive abnormalities such as myopia, hyperopia, astigmatism and other eye diseases be detected early, but also those children at high risk who have not yet developed myopia but are prone to develop myopia, and targeted interventions can be made for these groups. Children with true myopia can receive timely and appropriate refractive correction; children with “pseudomyopia” can recover normal vision through appropriate treatment; and children who are not yet myopic but are prone to develop myopia can be urged to pay attention to eye hygiene, have their vision checked regularly, and control the occurrence of myopia.
