Recently, two “Apple classes” were opened in Shanghai Jiading Experimental Primary School, where students brought their own Apple tablet computers (iPads) to class to experience the “digital learning style”. It is understood that the two “Apple classes” are opened in the first grade, with a total of 90 students. According to the plan, students in the “Apple class” will use Apple tablets for about one hour a day for language and mathematics lessons and after-school homework. The school has also developed some software. This turns the tablet into an aid for classes and enhances teacher-student interaction, which can improve children’s learning efficiency, but at the same time some parents are worried that their children’s eyesight will be affected? Myopia is a condition in which the eyes cannot see distant objects and can only see near objects. The reason for this condition is the excessive elongation of the anterior and posterior diameters of the eye, which causes distant objects to fail to focus on the retina and form a focal point before the retina, forming a diffuse circle on the retina, thus leading to blurred imaging of distant objects. With the continuous progress of modern civilization, myopia has become one of the most prevalent eye diseases among children in China, and the disease is gradually developing at a younger age. Since myopia can cause a lot of inconvenience to patients and may increase the chance of blindness such as retinal detachment and macular degeneration, many parents attach great importance to it. Many children’s eyesight decreases very quickly after the summer and winter vacations, and one important reason for this is the unscientific use of eyes. Many children now like to play iPad, because the tablet computer iPad has the function of playing games, which is very attractive to children, and children often stare at the screen for more than an hour without turning their eyes and do not know how to get tired, long time to look close to make the eye has been in a state of regulation, responsible for the eye zoom ciliary muscle will remain tense, until the spasm can not relax, so that the eye loses the ability to zoom. This causes regulatory myopia, or pseudomyopia. In addition, although the tablet iPad screen resolution is very high, but because the electronic screen is still in a constant state of flicker, look at a long time can aggravate the visual fatigue. Long-term visual fatigue and adjustment spasm will make the pseudomyopia slowly evolve into irreversible true myopia. When children spend too much time with their eyes, their eyes blink incessantly. In fact, frequent blinking is a sign of excessive eye strain. And staring at the screen for a long time will also reduce the number of blinks, resulting in dry eyes and discomfort, which can easily lead to dry eye syndrome and, in serious cases, keratitis or conjunctivitis. It is recommended that children should not use the iPad for more than half an hour continuously, and it is best not to choose those games with strong blinking images. When in the text reading interface when the backlight at 50% or less will be softer, too bright on the eye stimulation is more obvious. Myopia prevention tips: children’s eye development to the age of twelve or thirteen years old will be approximated to adults, if the final development of stable, it will take until after 18-20 years old. It is recommended that parents do not give younger children access to iPads. parents of older children should control the time and only play for half an hour. Although the iPad can temporarily meet the blind spot in parental education, but by no means all, in the company of parents to play a greater educational function of technology products. In the end, it is only an auxiliary tool. It is best to control the time when using the iPad, taking a 10-minute break every 20 minutes, which is also cultivating the child’s self-control. The best way to relax your child’s eye muscles after using the iPad is to look at it from a distance during the break plus eye exercises. Proper sitting posture, head should be put straight, back should be straight, try not to hang your arm when playing iPad games or interacting with educational functions, it is better to put a support at the elbow to reduce the force on the wrist, and keep a distance of 50 cm from the iPad. Children in the formative years should interact more with people and exercise their language skills. Long-term exposure to electronic products can easily make children become silent and lonely inside. Parents should make good use of iPads to help their children learn and develop intellectually, guide them properly, strictly control playtime, and cultivate a wide range of interests. They should increase the amount of time children spend outdoors every day and encourage them to look farther away. If they can spend 2~3 hours outdoors every day, they can effectively control the occurrence and progress of myopia. ? Parents should pay attention to the nutrition of their children’s eyes while paying attention to the nutrition of their children’s whole body, with a mix of grains and cereals, meat and vegetables, more green vegetables, and not partial food.
