Will myopia cause blindness?

Abstract: Generally speaking, one of the major causes of blindness in high myopia is retinal detachment. When there is an occasional eye shadow accompanied by a certain sense of flash, it is necessary to be alert and go to the ophthalmology for professional examination in time.

myopia is a very common disease nowadays. A survey shows that the number of myopia in China has reached about 450 million, that is, one in three people is myopia! It may also be because it is too common. Many people don’t pay much attention to myopia. They feel that they are myopic around them. Wearing glasses doesn’t affect their life, so there’s no big problem. The harm of

and

myopia is much greater than people think, especially high myopia. If it is not corrected scientifically, it may even cause blindness!

myopia can also cause blindness? Scared me into wearing my eyes. So is there any basis for this statement? From the principle of myopia,

and

healthy vision is called emmetropia, which means that when the eye is in a relaxed state, the external parallel light is refracted through the refractive system of the eye, and the focus just falls on the retina, which can form a clear image; Myopia is that after the parallel light is refracted by the refractive system of the eye, the focus falls in front of the retina and can not form a clear image on the retina.

why can’t myopia make light fall on the retina? This is because in the process of myopia, the eyeball will be elongated to form an irregular sphere like “football”, which will lead to the lengthening of the ocular axis and the atrophy of the fundus retina and choroid.

for high myopia (more than 600 degrees), the degree of vitreous stretching is longer, and the degree of fundus disease and macular disease is higher. A variety of complications, such as retinal detachment and fundus hemorrhage, may lead to blindness.

When there is a serious visual impairment, people think of going to the ophthalmology for examination, but it is often too late at this time, which may have produced serious symptoms such as retinal detachment, hole and macular disease. When there are irreversible visual problems, even manual surgery can hardly achieve the ideal correction effect.

generally speaking, one of the major causes of blindness in high myopia is retinal detachment. When there is an occasional eye shadow accompanied by a certain sense of flash, it is necessary to be alert and go to the ophthalmology for professional examination in time.

at ordinary times, we can also prevent retinal detachment by the following methods:

1 Pay attention to eye hygiene. Do not rub your eyes with your hands. Rubbing congested eyes with unclean hands is easy to cause eye inflammation and further induce retinal detachment.

  2. Avoid lifting heavy objects. High myopia should try to avoid lifting heavy objects, because when lifting heavy objects, it will aggravate the blood circulation of the body, so as to affect the blood circulation in the eyes and induce retinal detachment.

  3. Avoid strenuous exercise. Due to the aging of the eye structure of people with high myopia and the spread of the retina, retinal detachment may occur when they perform violent sports such as bungee jumping, roller coaster and football.

  4. Pay attention to “eye care”. If you use your eyes too much, you should pay attention to the maintenance of your eyes, eat more fruits and vegetables rich in vitamin ABC, carry out more outdoor activities, do eye exercises and hot compress after work, which can

and

5 Check your eyesight regularly. Because retinal detachment is not obvious in the early stage, people with myopia had better keep the habit of checking their eyesight regularly, once every six months, find the changes of eyesight in time and take preventive measures.

and

experts remind that the blindness caused by myopia has increased year by year in recent years, but few can recover. If you have cataract, you can change a lens, but each cell in the retina corresponds to a nerve. Once it falls off, there is almost no possibility of transplantation. Therefore, we must take good care of our eyesight, especially children. If parents do not pay enough attention to children’s myopia in childhood, the damage will be lifelong.
