Abstract: empirical results show that outdoor activities can prevent the occurrence of myopia and delay the deepening of degree. Its protective effect may come from the fact that sunlight will increase the secretion of dopamine in retina, and then inhibit the elongation of ocular axis; Moreover, outdoor long-distance vision can also reduce eye muscle tension and delay eye growth., During the summer vacation, many children are happy to get rid of the pressure of schoolwork and stay at home to play video games and watch TV. However, experts remind that regular contact with 3C screens can easily cause damage to the lens and retina. They call on parents to pay attention to their children’s vision every day, avoid staring at the screen for a long time, and arrange outdoor activities for at least 2 hours every day, which can prevent myopia or deterioration of vision., Vision loss try this method “width =” 400 “height =” 300 “SRC =” / / img jianke. com/article/201509/20150913194101277. Jpg “/ >, 3C product blue light stimulation is easy to cause damage to the retina. Blue light is easy to penetrate the lens to reach the retina, and the lens of infants and young children is completely transparent, resulting in macular lesions; The older the age, the higher the ratio of blue light absorbed by the lens, and the faster the cataract is produced. Other effects on eyes include dry eye, visual fatigue, glaucoma, retinopathy, optic neuropathy, blindness and so on., The empirical results show that outdoor activities can prevent the occurrence of myopia and delay the deepening of the degree. Its protective effect may come from the fact that sunlight will increase the secretion of dopamine in the retina, and then inhibit the elongation of the ocular axis; Moreover, outdoor long-distance vision can also reduce eye muscle tension and delay eye growth., During the summer vacation, try to arrange children to walk outdoors for at least 2 to 3 hours a day, avoid sticking to the screen, use their eyes for 30 minutes and rest for 10 minutes, which can reduce the occurrence and deterioration of myopia, improve their physical fitness, learning ability and reduce obesity., During the summer vacation of
, many children are happy to get rid of the pressure of school work and stay at home to play electric games and watch TV. However, experts remind that blue light is easy to cause damage to the lens and retina when they are often exposed to 3C screens. They call on parents to pay attention to their children’s vision every day, avoid staring at the screen for a long time, and arrange outdoor activities for at least 2 hours every day, which can prevent myopia or deterioration of vision.
