Many people think The consequence of myopia is that you can't see clearly. Just get the right glasses Even if the degree increases Just a new pair of glasses However, when myopia increases Developing into high myopia The damage to the eyes is unbearable When the eyeball is relaxed, if the myopia degree is ≥ 600 degrees , it is considered high myopia. Image source: Photo Network High myopia is the result of the combined effects of genetic and environmental factors. Genetic factors If one of the parents is severely myopic, the child's risk of developing high myopia increases by 2.99 times; if both parents are severely myopic, the child's risk of developing high myopia increases by 10.74 times. Image source: Photo Network But it doesn't mean that if the mother and father are highly myopic, the child will definitely be myopic, but the possibility is higher . During the growth and development of the child, if you pay attention to prevention and protection, you can also maintain normal vision. Environmental factors **Excessive use of the eyes at close range, too little time spent on outdoor activities, incorrect writing posture, too long use of electronic products, unbalanced nutritional diet...** may all cause the degree of myopia to increase rapidly! Image source: Photo Network The axial length of the eye of people with high myopia will grow, the posterior wall of the eyeball will be forced to expand backwards, and the structure of the eyeball wall will become thinner. It can be imagined as blowing up a balloon. The more you blow the balloon, the bigger it becomes, but it also becomes thinner and more fragile. In addition to damaging vision, high myopia may also cause other hazards: Retinal detachment As the axial length of the eye increases, the retina may become thinner and develop areas of degeneration, which are prone to holes and the development of retinal detachment. Image source: Photo Network Macular degeneration High myopia may lead to pathological changes in the retina in the macular area, such as macular hole, epiretinal membrane or macular schisis. In addition, high myopia may cause the growth of new blood vessels under the retina, which are very prone to rupture and bleed, leading to macular hemorrhage and macular degeneration. cataract High myopia may change the metabolism of the lens, causing the lens to gradually become cloudy and increasing the risk of cataracts. glaucoma High myopia can easily cause increased intraocular pressure and increase the risk of glaucoma. Vitreous degeneration The growth of the eye axis may lead to vitreous liquefaction, increased mobility, and the appearance of floaters. In severe cases, it may induce retinal detachment. 1 Regular inspection It is recommended that friends with high myopia have an eye examination every six months, especially a fundus examination , so as to detect and treat retinal problems in a timely manner. Image source: Photo Network If you see dark shadows, flashing lights, or decreased vision in front of your eyes , go to the hospital immediately to check whether you have retinal tears, detachment, or other problems. 2 Avoid strenuous and high-impact activities Friends with severe myopia are advised not to participate in intense and high-impact activities such as skydiving, diving, bungee jumping, and roller coasters. They should also try to avoid eye concussions and reduce heavy physical labor in their daily lives. But not being able to do strenuous exercise does not mean not being able to exercise. You can still do general aerobic exercise such as walking, jogging, yoga, etc. 3 Maintain good eye habits Try not to read or use electronic devices for a long time. It is recommended to take a break every once in a while and look into the distance. You can also do more outdoor activities in your daily life. 4 Proper nutritional supplementation Eat less sugar and high carbohydrates, and supplement vitamins and trace elements in moderation, such as vitamin A, B complex, calcium, chromium, zinc, etc. You who read this article Remember to take a break and look out the window Good for eyes Statement: This article is a medical-related educational popular science article.
