Currently, the entire nation's number of glasses wearers has already exceeded 300 million, with 33% of China's nearsighted patients already accounting for the world total, which is on average 10% higher than the world level. Regarding the causes of myopia among adolescents in today's China, former director of Beijing Hospital's Ophthalmology Department, colleague, associate researcher, and member of the Ophthalmology Branch Committee of China, Professor Zheng Yuanyuan, believes: Genetic factors, nutritional constitution factors, and environmental factors are the three major inducements causing teenage myopia, and among them, the environmental factor is the main reason leading to a significant increase in the incidence of teenage myopia in China. Adolescents are in a vigorous growth period; the physiological functions of their eyes and structural composition have characteristics that differ from other periods, with strong adjustment capabilities and greater elasticity of the eyeball wall. Poor environmental conditions easily affect and form myopia due to long hours of watching TV, playing computer games, incorrect reading postures, and writing incorrectly. These create an undesirable environment that leads to teenage myopia. Among these, watching TV is one of the main reasons causing children's myopia. Staring at the TV for extended periods can produce eye fatigue, and excessive eye strain is a primary factor in the rising incidence of teenage myopia. According to U.S. statistics from 1988, children who watch color television continuously for more than an hour can experience a 30% drop in vision. Therefore, preventing teenage myopia requires action from every family. Parents should bear the main supervisory responsibility in building a conducive environment at home. Experts suggest that family protection plans can start from the following aspects: First, change gaming methods: Modern city children’s gaming methods mostly prioritize indoor activities such as TV, individual sports, replica Gucci sunglasses, computers, etc. For this, parents should encourage children to change their gaming methods and engage in outdoor activities more. Second, pay attention to eye hygiene: Teach teenagers to pay attention to eye hygiene. Notice the distance between the eye and the book when reading, maintain proper posture, do not lie down or walk while reading (Cartier glasses). Ensure sufficient lighting when reading, take breaks after reading or writing for 40 minutes, look far away, and avoid indulging too much in sports or watching TV. Third, pay attention to eye care: Insist on doing daily eye exercises (those with fast rhythms alternate looking far and near), massage acupoints (eyeball bright, sky waist bamboo assembly, fish, traditional stringed and woodwind instruments, bear sobbing, waiting in vain), and conduct mist inspections (wear +1.50D glasses for distant inspection). Fourth, if vision drops, seek medical examination and treatment promptly. Additionally, dietary habits and nutrition should be considered to prevent deficiencies in trace elements such as chromium and calcium. What makes experts anxious is that it is indeed very difficult to make adolescents completely break away from TVs and computers. From a social perspective, he suggests that parents would rather choose a few pairs of protective TVs or computers designed specifically for teenagers' eyes. This way, the harm to adolescents' eyes can be minimized. The expert mentioned that if we want to protect children's eyes, televisions must meet the following requirements: First, brightness must achieve a level suitable for the human eye, namely a color temperature of 5500-6500K, with average brightness ranging from 100-200 (Cd/m²). It cannot be too dark or too bright, which helps with children's eye development. Second, colors must be pure, and the combination of three base colors should be smooth and consistent with natural colors, protecting children's eyesight and allowing them to differentiate colors correctly. Third, when watching TV, the screen appearance should not flicker. Trends should be mixed accordingly, keeping consistent with the incomplete shadow cycle of the eye, ensuring good eye focusing and preventing fatigue.
