With the progress of science and technology, the development of electronic information technology and the accelerated pace of urban construction, while changing our lives, it also brings some negative effects. For example, people are now concerned about air pollution, water pollution, noise pollution, these pollution directly endanger our human health. However, there is a kind of pollution, we may rarely know or concern about it, in fact, it also has an impact on our health, especially on children’s eye development, which is light pollution. So, what is light pollution, light pollution mainly from the human living environment of daylight, light and a variety of reflective, refractive light sources caused by a variety of excessive and uncoordinated light radiation. The human body in the light pollution is the first victim of direct contact with the light source of the eyes and skin, the impact on infants and children is greater, stronger light will affect the development of children’s vision. 1, light pollution to bring the baby those injuries (1) retinal macular damage: the most sensitive part of the retina of our eyes is the macula. Once the macula becomes diseased, vision will be significantly reduced, and may even lead to blindness. Many light sources in life contain blue light, such as sunlight, lights, computer monitors, iPads, large-screen cell phones, etc., which can cause damage to babies’ eyes if they look at them for a long time. The younger the baby, the poorer the ability of the eyes to filter blue light, prolonged gaze at strong light sources can easily cause light damage, thus affecting the child’s eyesight. (2) Lens damage: Our human lens can filter external light, if the eyes are exposed to ultraviolet light for a long time, it will accelerate the pace of crystal clouding, leading to the early appearance of acquired cataracts. (3) Damage to the cornea and conjunctiva: The cornea is a transparent membrane located on the most surface of the black eye of the human eye, and the bulbar conjunctiva is a membrane covering the surface of the sclera, which plays the role of protecting the eye. Strong strong sunlight, light, laser can cause damage to the cornea and conjunctiva, eye redness, eye pain, thus causing vision loss. 2.Where does light pollution hide? In our daily life, strong lights, electronic products screen reflection, bath light, fireworks light, welding light and other such light can cause light pollution to children’s eyes. Common light pollution are the following: (1) strong lights: babies often like to stare at the lights without turning their eyes, if the lighting at home, decorative lights, spotlights are too bright, his eyes will cause damage. Nowadays, buildings and landscape lighting are often also very harsh, which is more attractive to babies, and the damage is more serious. In addition, nighttime headlights and neon lights also need to be careful not to stare. When taking pictures of your baby, use as little or no flash as possible. When your baby needs lighting for reading, it is best to use an eye protection lamp. (2) TV, computer, iPad, cell phone: these commonly used electronic products screen itself emits light, if a long time to look at will be harmful to the baby’s eyes, and constantly flashing, fast-changing images are also easy to cause eye fatigue, baby should not be used for a long time, it is recommended that a use time of no more than 20 minutes, and to maintain a certain distance, do not get too close. (3) toys and pens with laser rays: there are many toys on the market with laser rays, and laser pens, very popular with children. If the laser rays directly irradiate the eyes, the damage to the eyes, especially the macula, is great. Therefore, parents do not tease the baby with a laser pointer, especially do not let him hold the laser pointer to play with himself, once the laser directly into the baby’s eyes, may cause damage to the eyes. (4) bath bombs: autumn and winter, in the bath, mothers usually have to use the bath bombs for heating, because of the bath bombs strong light, parents in the use of the same time, must not ignore the bath bombs strong light on the baby’s eyes, should avoid the baby’s eyes directly to the light of the bath bombs. (5) welding light: the strong light generated by welding, ultraviolet light intensity is very high, if the baby stares at the welding light, can cause electro-optic uveitis. Therefore, in daily life, when encountering welding work, the mother take the baby away. (6) fireworks: the light emitted during the close burning of fireworks is very strong, the baby can not look for a long time, it is recommended that when watching, it is best to watch indoors through the glass, not too long. 3, how to keep the baby from light pollution from the above account we have learned that those who may cause light pollution, we should do in our daily lives: (1) avoid contact with strong light sources: home decoration is best not to use very smooth marble or glass floor, furniture also try not to choose the more reflective materials. Try not to paint the walls of your baby’s bedroom and playroom pure white, don’t stay in the snow for too long on sunny days in winter, and bring a sun hat and sunglasses when playing on a beach vacation. Do not let your baby gaze at neon lights and underground spotlights for a long time. (2) Don’t turn on the lights when your child is sleeping. Studies have found that any artificial light source produces a subtle light stress. The long-term existence of this light pressure will have an impact on the human nervous system, which can make people, especially infants and young children behave restlessly, emotional restlessness, so that it is difficult to sleep. At the same time, let the baby sleep under the light for a long time, and then affect the brain reticular activation system, resulting in shorter sleep time, shallow sleep depth and easy to wake up. In addition, the baby sleeps under the light for a long time, causing the eyes and ciliary muscles can not get sufficient rest, and it is easy to cause myopia. (3) Do not let children watch electronic products for a long time. Long time looking at the screen of electronic products, the child’s eyes and brain may be affected. It is recommended that infants within 1 year of age do not watch television, watch television after 30 minutes to rest for a period of time, more take the baby to play outdoors, can effectively avoid light damage, and can effectively prevent myopia. Therefore, for those young fathers and mothers, do not let your baby contact with electronic products too early, take your baby to outdoor activities more often, sleep at night without lights, to avoid those light pollution in life to cause damage to the baby’s eyes.
