When I was four or five years old, the kindergarten teacher found that Xiaoyu could not see the teaching content clearly. So my mother took him to the hospital for examination. The examination results showed that Xiaoyu had myopia of more than 400 degrees and quickly put on glasses. However, after putting on glasses, Xiaoyu still kept his phone all day long.
Last week, Xiaoyu came to Changsha Aier Eye Hospital for treatment again.
After the examination, the doctor told his mother that Xiaoyu's myopia rate was as high as 1300 degrees, and the best vision after wearing glasses could only reach 0.5. For adults with normal vision, the eye axis length is about 22~24mm, while Xiaoyu's eye axis has reached an astonishing 32mm. But even so, Xiaoyu was still immersed in mobile games.
"Simply put, the eye axis is the diameter of the eyeball from front to back." Dr. Li Xiaoning, director of the Department of Optophoresis of Changsha Aier Eye Hospital, , explained, "Generally, a normal eyeball is like a table tennis ball, and the eyeball of a myopic person will become an egg-shaped oval, and the eyeball will protrude forward. Usually, every 1mm increase in the axis of a child, myopia will deepen by 200 degrees."
Dr. Li Xiaoning, director of the Department of Optophoresis of Changsha Aier Eye Hospital, , emphasized that once the eye axis is lengthened, the light imaging entering the eyes is in front of the retina, resulting in unclear viewing. And the lengthening of the eye axis is irreversible.
▲Myopia (left) eyeballs are more prominent
For this reason, Director Li Xiaoning refitted Xiaoyu with glasses and arranged further examinations.
Diet, training classes, eye use habits, etc. are all causes of myopia in children
"Myopia in children and adolescents has long become a serious problem, especially in outpatient clinics, which are more and more young children with high myopia, and many children have myopia degrees as high as 1,000 degrees." Dr. Li Xiaoning, director of the Department of Optometry of Changsha Aier Eye Hospital, introduced that, like Xiaoyu, high myopia at a young age, is caused by birth, in addition to congenital dysplasia, more of it is caused by acquired reasons. , such as long-term indulging in electronic products, consuming too much sweets, excessive training on high attention such as Go, painting, piano, etc., and bad eye-using habits such as doing homework, writing, and reading.
protects children's vision. Parents should be good gatekeepers
Myopia not only affects children's study and life, but also increases the development of visual function, which may cause lifelong vision defects. Adolescents with high myopia will not only have 10 times more likely to have cataracts, , glaucoma, , retinopathy, etc. in adulthood, but may also lead to psychological problems such as social inferiority complex.
Therefore, Dr. Li Xiaoning gave several suggestions:
1. Reduce the use of electronic products. If you have to use electronic products to teach, try to choose a large-screen device terminal and try to use your mobile phone and computer as little as possible;
2. Strictly implement "4 20" -use your eyes for 20 minutes each time, rest for 20 seconds, look into the distance for 20 feet (about 6 meters), blink 20 times to relax;
3. It is recommended to check your vision at least twice a year and establish a vision tracking file;
4. In daily diet, appropriately increase foods containing calcium and vitamin E, eat more coarse grains, and eat less fried and sweets;
5. Try to ensure that your sleep time is 8 hours, and you can exercise outdoors for 2 hours under natural light every day.
