Does myopia really cause blindness? Experts say: There is really a possibility!
Let's first understand why we are short-sighted. The main reason for myopia is actually the increase in the distance between the eye axis, resulting in visual imaging can not accurately fall on the retina, and things will be blurred. The higher the degree of myopia, the longer the eyeball, the thinner the inner wall of the eyeball, which can lead to a series of eye diseases. For example, the retina will become thinner and thinner, and if the retina is not strong enough, it will fall off and lead to blindness.
Whether it will cause blindness, there is a threshold. 600 degrees is a watershed, myopia below 600 degrees is not easy to get fundus diseases, and there will be no blindness. If it exceeds 600 degrees, the eyes are prone to fundus diseases, such as glaucoma, cataracts, etc. Once pathological myopia becomes pathological, the likelihood of blindness increases dramatically.
Ophthalmology believes that 100 degrees - 300 degrees is mild myopia; 300 degrees - 600 degrees is moderate myopia; above 600 degrees is high myopia. The higher the degree of myopia, the easier it is to get fundus diseases and the easier it is to become blind.
What diseases caused by myopia can cause blindness?
1. Retinal detachment
Patients with high myopia are about 30 times more likely to have retinal detachment than ordinary people, and there will be signals before retinal detachment, such as a "flashing sensation" in front of the eyes.
2, Cataract
Cataracts are currently the number one blinding eye disease in the world, and people with high myopia are 3 times more likely to develop the disease than the average person. Many people think that the eyes will turn white with cataracts, but they are not. The eyes of cataract patients will look cloudy and yellow, and there will always be a layer of white fog in front of the eyes when looking at things, and things will change color and deform. In the late stage, it is even more miserable, and you can only see a little light in front of your eyes, so you must take good care of your eyes.
Friends with myopia should pay more attention and be careful to develop into high myopia. Myopia is irreversible, especially in myopic children who are in the growth and development stage, it is necessary to delay myopia in place. Scientific prevention and control of myopia, we must grasp the fundamentals. Mastering these four tricks can help parents scientifically guide their children to prevent and control myopia.
1. Reduce the use of eyes at close range
Make a reasonable learning plan for your child, reduce the close reading and writing, and for every 40 minutes of continuous close reading, you should rest for 10 minutes.
2. Sufficient outdoor activities
A growing body of research and evidence suggests that outdoor activities can effectively control the occurrence and development of myopia, and the mechanism lies in the fact that outdoor sunlight can promote the secretion of dopamine, and dopamin can inhibit the growth of the eye axis. Therefore, it is recommended that children do outdoor activities for 2 hours a day, go outdoors during recess, and do not stay in the classroom.
3. Pay attention to adjusting diet and living habits
An irrational diet leads to insufficient nutrition for the eyes and can also cause vision problems. "The spleen and stomach are the foundation of the day after tomorrow, the source of the ascension of qi and blood, and the weakness of the spleen and stomach is the dereliction of duty, the eyes cannot be bloody, and the divine light cannot be far-sighted." Poor spleen and stomach transport, or nutritional deficiencies caused by the child's picky eating, are also the causes of myopia in children. Therefore, the eyes should be supplemented with nutrients such as lutein in time and adjusted their living habits. Eye care can also be used to care for the eyes.
4. Scientific prevention and control plan
Before the child goes to school, around the age of 7, he needs to go to the optometry institution to establish a vision file, and if the child has myopia symptoms after school, he will take the child to the optometry institution in time to correct it, in order to control the development of myopia and block the harm of myopia.
