The harm of juvenile myopia
The eye is the window for human beings to perceive the world. However, in recent years, the problem of juvenile myopia has become increasingly serious. According to Dr. Sun Yi, ophthalmologist of the Third Hospital of Zhongshan, Guangzhou, the harm of juvenile myopia cannot be underestimated. Myopia not only affects vision, but also may lead to eye fatigue, asthenopia syndrome, dry eyes and other eye diseases. Therefore, it is very important to prevent and control juvenile myopia.
Correct eye posture
First, teenagers should use their eyes correctly. Keep a certain eye distance to avoid excessive eye use for a long time. Take a 5-10 minute long view every 60 minutes to relieve eye muscle fatigue. In addition, the reading posture should be correct, and you should avoid reading with your head down for a long time or using electronic equipment. Avoid overloading the eyes with excessive eye use.
Secondly, keep the reading distance wide and far. When reading, keep 30-40 cm away from the book. At the same time, avoid reading in a dark environment and maintain sufficient light to help alleviate eye fatigue.
Finally, when using electronic equipment, you should maintain correct eye posture and avoid staring at the screen for a long time. At the same time, appropriate screen brightness and contrast should be set to reduce eye fatigue. Regular eye exercises can effectively relieve eye muscle fatigue and protect eye health.
Scientific control of eye use time
Another important factor of juvenile myopia is excessive eye use for too long. Scientifically control the time of eye use, and arrange appropriate rest time every day. According to Dr. Sun Yi's suggestion, after every 40-50 minutes of continuous eye use, you should take a 5-10 minute rest to fully relax your eyes. It can carry out simple eye exercises, outdoor overlooking, etc. to promote the blood circulation of the eyes and alleviate eye fatigue.
In addition, the time spent using mobile phones, tablets and televisions should be limited. Try to avoid using these electronic devices continuously for a long time, take regular breaks, and try to reduce the use of these devices at night.
Scientific control of eye use time is an important aspect of prevention and control of juvenile myopia. Parents and schools should pay attention to and actively cooperate.
Keep a good indoor environment
Adolescent myopia is also related to environmental factors. Good indoor environment can reduce the occurrence of myopia. Keep proper humidity and temperature in the room to avoid excessive drying or humidity. Proper lighting is also important. Avoid using too bright or too dark lights.
In addition, pay attention to indoor ventilation and keep the air fresh. Frequent opening of windows for air exchange helps to reduce the irritation of indoor harmful substances to eyes.
Parents and schools can work together to provide a good indoor environment for teenagers and protect their eyesight.
Wear glasses correctly
It is also very important to wear glasses correctly for teenagers who are nearsighted. The degree of glasses should be determined according to personal conditions. Too high or too low degree will have adverse effects on the eyes. Therefore, Dr. Sun Yi suggested that teenagers should check their eyesight regularly and adjust their glasses in time.
In addition, proper glasses wearing also requires attention. The glasses should be selected in a style and size suitable for personal use to avoid wearing too tight or too loose. Clean the glasses regularly to keep the lenses clear and avoid dust or oil stains affecting the visual quality.
By wearing glasses correctly, vision can be effectively corrected and the process of myopia can be reduced.
To sum up, the prevention and control of juvenile myopia can start with correct eye posture, scientific control of eye time, maintaining a good indoor environment, and correct glasses. These methods have certain effects and play a positive role in the prevention and control of juvenile myopia. The problem of juvenile myopia needs to be attached great importance by parents and schools to jointly protect the eyesight health of adolescents.
