Is it good or bad to have myopia?

Let's see if it's good down there!! What everyone must know [eye protection tips] 1. More than 600 degrees is high myopia - lesions will occur - a small number of serious ones will be blind! (Even if you are highly myopia, there is no pressure, as long as you pay attention to protection, there will be no serious consequences) Second, true myopia should wear glasses - squinting desperately without glasses will aggravate eye fatigue and rapid vision decline.

Third, the surgery is to correct vision rather than **, which has certain risks compared to wearing ordinary glasses. Surgery is best done after the adult eyeball has been shaped. If you don't pay attention to protection, you still have close fatigue with your eyes.

It will continue to decline after surgery. There is currently no clinical data on the condition of the eye after 20 years of surgery. Therefore, there is a certain risk of poor prognosis.

There is currently no ideal vision for myopia**. The descent can only be stopped by attention protection. Be cautious about some advertisements, and it is also a misunderstanding that you should not be farsighted after old age!

You see the old professor with 2 glasses, one nearsighted and one farsighted, presbyopia is degenerative in addition to farsightedness, so myopia is as farsighted as old age. Besides, it's normal for old people to have bad eyes, they don't participate much in society, and they don't have much impact, so young people !!

Myopia, not a question of whether it is good or not, but to see whether it is caused by improper use of eyes or pathological, people with myopia will be a little later than people with farsightedness and flat people, but everyone will have presbyopia, this is a physiological phenomenon, anyone is inevitable, but people with myopia just offset in a certain period of time (related to the degree), at that time some people can not wear glasses.

The eye is like a camera, and the entire transparent medium of the eye includes the cornea, lens, vitreous humor equivalent to the lens, and retina equivalent to the negative film. We see a clear image when light rays converge through the transparent medium of the eye and fall on the retina. The axis of the myopic eye is too long, so the distant light cannot reach the retina, so it is blurred and myopia is formed.

So, why do people become short-sighted?

1.Genetic factors: Children with both parents are nearsighted and have more than twice the risk of myopia compared to children with neither parent being myopia.

This is well understood, and the role of genes cannot be ignored. In addition, there are some environmental factors, such as myopic parents tend to read for a long time, and children are more likely to like to read.

2.Looking at the distance between east and west: the nature of the work, the level of education, etc., these are self-evident.

3.The diopter of the eye does not reach metropia: the fact is that the average diopter of the baby's eyes at birth is 200 degrees of hyperopia (there is a wide range, from 600 degrees of myopia to 1100 degrees of hyperopia, but most newborns are concentrated around 200 degrees of hyperopia), and attention is paid to hyperopia rather than myopia.

Then, at 18 months, this huge difference between people basically disappears, and everyone is almost stable at 125 degrees of farsightedness, a process called emmetropia. Emmetropia refers to the state in which the growth and development of the eye reaches emmetropia, and the eye's ability to concentrate light and the length of the eye axis coincide. It is conceivable that if the ancient way of life of hunting and animal husbandry were followed, the degree of human eyes would be fixed until they died of illness and starvation or were eaten by tigers.

There are two causes of myopia.

First, innate factors, second, environmental factors. Congenital myopia is mainly manifested as high myopia, both parents are highly myopic, 100% of children are highly myopic parents, 50% of children are highly myopia, and 50% of children are highly myopia. The main reason for the appearance of myopia in the eyes is that there are certain genetic factors, but at the same time, it is also considered that the eyes are not well fortified, such as frequent staying up late or frequent excessive eye fatigue, which can easily lead to the formation of myopia.

Usually pay more attention to rest, do not overuse your eyes, make your eyes too tired, and you can also do more eye exercises. Bad eye habits only induce myopia, not the root cause of myopia. People who do not have myopia genes will not be myopic no matter how they use their eyes (there are not excluded cases of extreme evil), while people with myopia genes will be myopic as long as they do not pay attention to it, and it is almost impossible to prevent it in the environment where modern life requires high-intensity eye use.

Myopia is not controlled by a single gene, and although there is a correlation between parents and children, non-identical siblings, the correlation coefficient is certainly much lower than that of identical twins.

The external environmental factors for the formation of myopia are mainly to see near for a long time, and the eyes are in a state of adjustment tension for a long time, resulting in excessive convexity of the lens and inability to return to its original shape, which in turn makes the anterior and posterior diameter of the eyeball too long, and the light of distant objects is focused in front of the retina, and distant objects cannot be seen clearly

Many people use their eyes irregularly, such as looking at their mobile phones while sleeping, looking at their mobile phones while lying down, the brightness of their mobile phones is too high, and many children wear glasses because the brightness of their mobile phones is too high.

Develop a good habit as a child and pay attention to visual fatigue.

Because it may be tiring to use it a lot.

It is generally believed that there are two major causes of myopia:

1. Hereditary myopia, hereditary myopia mainly includes high myopia, high astigmatism, and family history.

2. Environmental myopia is caused by environmental factors, which are related to people's living habits, living environment, and excessive eye use.

The living environment is manifested in the fact that modern people spend more and more time in the house, and the time outdoors is getting less and less, and the eyes do not have the opportunity to relax and look into the distance.

The habit of life is because modern people spend more time sitting and reading, sleep for a shorter time, and rest irregularly.

The problem of eye hygiene, from books to computers, has increased the load on the eyes, increased myopia, from the computer to the mobile phone, now everyone is looking at the mobile phone all the time, which is equivalent to using the eyes all the time, and in the case of excessive eye use, myopia is gradually deepening.

If you don't have high myopia at home, it may be caused by overuse of your eyes.

After the formation of myopia, it is necessary to go to the hospital to pass the eye examination, which can clarify the degree of myopia, wear appropriate glasses in time, avoid eye fatigue, and prevent the power from continuing to grow.

In the case of high myopia, it is also necessary to pay attention to the problem of fundus comorbidities. For moderate and low myopia, the rate of progression of myopia can be alleviated if the eye is properly controlled, the living environment is improved, and outdoor activities are more.

Because I don't take good care of it, I often look at my mobile phone and computer, and I don't pay attention to the distance when I write, and I will definitely be short-sighted.

Long-term overuse of the eyes can lead to myopia. It is recommended that you use your eyes for about half an hour, close your eyes and rest for a while, or look into the distance for 10 minutes to relieve eye fatigue. Eat more vegetables and fruits, pay attention to maintaining good eye habits, and avoid looking at mobile phones and computers at close range for a long time.

Anti-fatigue eye drops can be used to relieve symptoms, or vitamin A and lutein can be taken orally. Children are prone to myopia, teenagers usually use their eyes too much and are also prone to myopia, all in the adolescent period, the body is still growing, myopia occurs during puberty, there is nothing to worry about, but it is rare to hear that adults will have myopia, because the eyes of adults have been fully developed, and the possibility of myopia is still relatively small, but as an adult, you also need to pay attention to the fact that excessive use of eyes will also cause myopia.

It is precisely because many adults feel that when they are older, there is nothing to worry about, and there will be myopia problems, so everyone begins to care about protecting the health of their eyes, and as a result, over time they find that they have problems with their eyes, and now our lives are inseparable from computers and mobile phones, and the most important thing is television.

Many young people are also prone to cataracts, this is because excessive use of the eyes for a long time will lead to eye compression, intraocular pressure rises to produce lenses, and the lens forms an obstruction behind the cornea, which will cause people to blur when looking at things, double vision when looking at people, and further aggravation may lead to glaucoma, or even blindness.

Don't think that adult myopia is not ordinary myopia, in fact, adult myopia is still more serious, although adult myopia has escaped the dangerous period, but it is usually recommended that minors read books for too long, because the fatigue of work plus a long time, need to face electronic products, on the contrary, such a result will lead to serious eye problems.

Here it is recommended that adults must pay attention to eye health is very important, so do not use your eyes too much, excessive eye use is not good for the eyes at all, and may even lead to various problems in the eyes, we must make various preparations and actively respond to prevent myopia from affecting our health.

Overuse of the eyes should be possible, but not in other areas.

Dangers of myopia:

1.Vulnerable to injury: After children with myopia and wearing glasses, due to their liveliness and activity, if they are accidentally hit and broken, the eyes will be punctured in the light, and the blindness will be caused in the worst cases.

2.Decline in academic performance: If you have myopia, you can't see words clearly without glasses, and it is easy to cause visual fatigue and lack of concentration after wearing glasses, which will reduce your academic performance.

3.Complications: If myopia is not timed, not only will the degree continue to deepen, and eventually become high myopia, but also lead to complications such as retinal detachment, macular hemorrhage, glaucoma and cataract, and even blindness in severe cases.

The impact is very great, some majors can not be reported, so it also affects learning, but also affects learning, so try not to be myopia, but this is not very easy to achieve, but it is better to try to keep good eyes.

Myopia has an impact.

Myopia can see clearly near and far, which will affect learning and life.

When the prescription increases to a certain extent, there is also a risk of fundus lesions.

It will also be passed on to the next generation.

Myopia needs to be protected from progressing to higher heights. In the future, the examination will also be affected. That's more than worth the loss.

Myopia is not as simple as a pair of glasses, especially for teenagers, the body is in the development period, plus the current excessive use of eyes, myopia will continue to increase after the degree, if it increases to high myopia, then the later stage will affect the fundus, the risk of fundus lesions increases, and even blindness, so once myopia, we must pay attention to prevention and control, to avoid high myopia;
