The increase in myopia is endangering the healthy growth of young people. In fact, simple low to moderate myopia is not terrible, you can wear frame glasses to correct, if there is a special need, you can wear contact lenses, and even excimer laser surgery can be done if conditions allow in adulthood. The problem is high myopia, that is, when myopia develops to a certain degree, causing the eye axis to become longer and the retina and choroid to degenerate, it may bring macular degeneration, retinal detachment, fundus hemorrhage, vitreous liquefaction after detachment, open angle glaucoma and other consequences. Therefore, the prevention and treatment of myopia has to become a high concern for people and ophthalmologists. The occurrence of myopia in adolescents is partly due to the genetic inheritance of parents with high myopia, but most of them are also caused by improper eye use. Some teachers will also change the child’s seat from the back row to the front row in order for the child to see clearly, and some people wear them when they are not, these actions are wrong and will affect the child’s visual development, in addition to leading to increased myopia, strabismus and amblyopia will occur. 1, completely reduce the burden of learning: At present, the only thing we can change is the learning environment and the time spent with the eyes. Myopia develops at a high rate from the age of 12 to 18, and stabilizes after 18. Because of the education system, this is the period of the heaviest study pressure, the busiest homework and the most homework, so that young people’s outdoor activities are significantly reduced, and they are in a long-term near-sighted state. For this reason, from an ophthalmological point of view, we should completely reduce the burden of study of students, to ensure that they work and rest regularly, sleep enough; return children to a happy childhood, in order to reduce the incidence of myopia to improve the health quality of the nation. 2, increase outdoor activities: modern children’s games are mostly indoor self-entertainment type, such as personal toys, game consoles, novels, computers, television, etc.; rarely see children in outdoor group games, such as hide-and-seek, jumping rubber band, etc., so that children in the little time after school also almost out of the house, every day rarely have the opportunity to get out of the near-sighted environment. For this reason, parents and teachers should encourage children to change the way they play and do more outdoor activities. 3, pay attention to eye health: to educate young people to pay attention to eye health, when reading pay attention to the distance between the eyes and the book, the posture should be correct, not lying down to read or walking while reading; pay attention to reading lighting to adequate light, work time should not be too long, after 45 minutes of continuous reading and writing, should rest for 10 minutes or look into the distance, so that the ciliary muscle to get a proper rest. You can also use eye exercises. Do not lie in bed to read, do not read on the road and in the open carriage, and do not read and write under strong sunlight or dark street lights, and not in close proximity to watch television programs for a long time, so as not to cause visual fatigue. Can not be too much indulged in game consoles, computers, television. 4, pay attention to eye care: regular vision checks, found vision loss should be promptly to the hospital for examination and treatment. The optometrists in regular hospitals will set up a follow-up file on the vision of adolescents: record the results of comprehensive refractive examinations such as bare eye vision and corrected vision, optometry, corneal curvature, eye axis length and intraocular pressure.
