What causes your myopia?

My myopia was due to the overuse of my eyes when I was a child, and then I especially liked to stay up late watching TV and stuff.

My myopia is caused by reading too much at night and looking at my phone too much. It's all due to improper use of the eyes.

Do I think myopia means that I often look at my phone? Then I looked at the mobile phone more, and I just knew how to play the mobile phone every day, and then after playing the mobile phone too much, it would cause myopia.

My myopia is caused by the wrong posture of reading by myself, and after myopia, it is really out of control, and the degree is getting deeper and deeper.

My myopia is because when I was younger, I used to like to play with my phone and stuff, and that's how it is.

Did I watch too much TV because I was nearsighted? When Rong was young, he used to watch TV, which caused me to be short-sighted.

Since I was a child, my eyes have been very close when I read books and play with my mobile phone, and now my myopia is very serious, and I can't go out without my eyes.

Myopia is watching TV, playing with mobile phones and computers must be these things, and there will be some lying on their stomachs to play and read books.

In the third year of high school, I did test papers every day, studied with my head down, and then my eyes were myopic unconsciously, which was actually very bad.

I regret my myopia, which made me regret it when I was a child, and I regretted that I was deliberately myopic when I saw others wearing glasses.

When looking at near objects, the ciliary muscles contract and the ciliary band relaxes, the lens thickens due to its elastic retraction, and the pupil dilation muscle contractions to make the pupil wide, and the refraction is enhanced, so that the image entering the eye can focus on the retina. When looking at distant objects, the ciliary muscles relax, the ciliary band is tightened, the lens is thinned, the pupil is narrowed by the contraction of the pupillary sphincter, and the image of the refractive attenuation remains on the retina.

Myopia: The ciliary muscles are tense and the lens thickens.

Farsightedness: The ciliary muscles relax (or even stretch) and the lens becomes thinner.

If the adjustment function is insufficient and the number of sails cannot be normalized, the object image falls on the retina, it is a refractive error.

Genetic factors.

A large number of surveys have shown that myopia has a certain genetic tendency, and it is often seen that families are clustered, and both parents or one parent are myopic, and the likelihood of myopia in children will increase. Among them, it is clear that the occurrence of high myopia is autosomal recessive.

Environmental factors. The incidence of myopia in patients with long-term near eye use is relatively high, which is also the main reason for the high incidence of myopia among adolescents in China. If you add to the factors such as poor ambient lighting, too small or blurred reading handwriting, too long continuous reading, and lack of outdoor activities, it will further promote the occurrence and development of myopia.

Predisposing factors. Studies suggest that micronutrient deficiencies, nutrient imbalance and air pollution may all be predisposing factors for myopia.

With the popularity of electronic products in recent years, long-term close viewing of electronic screens may also promote the development of myopia.

1. Diet matching.

The influence of unreasonable dietary combination, such as eating too many sweets, and the addition of sugar content will lead to changes in the osmotic pressure of aqueous humor and crystals, resulting in the onset of myopia. Excessive intake of sugar and high carbohydrates will also reduce the elasticity of intraocular tissues, reduce the storage of trace element chromium, and make the eye axis longer.

2. External trauma.

After the impact of uncertain factors such as car accidents on the eyes or brain, affecting the optic nerve or other factors can easily lead to high myopia. The presence of biologically active substances in the retina is directly or indirectly involved in the formation of form-deprivation myopia.

3. Academic pressure.

The main reason for myopia is that children are under too much academic pressure now. The main group of people with myopia now is students, and the pressure on students now is much greater than that of students in the previous era, and with the development of education in the past few decades, it is more difficult for children to learn things than in that era, and the pressure of competition is much greater than that time.

4. The emergence of various electronic products.

Children born in the post-80s and early 90s, their childhood should be spent in playing with their friends, all kinds of games are fun, an eagle can catch chickens to play, but now ipad, only mobile phones and other functional electronic products appeared, most people are playing with mobile phones day by day, which greatly increases the myopia rate of this generation.

Staring at electronic products for a long time is easy to cause visual fatigue, but this kind of visual fatigue is likely to ignore it because of the fun of the mobile phone, which is easy to appear myopia.

5. Hereditary factors.

When the degree of myopia reaches more than 600 degrees, your myopia has a great chance of being passed on to the next generation, and you should be able to meet some classmates who wear glasses in elementary school, and some people even have thick lenses.

If this is explained quietly with excessive use of eyes, it is a bit difficult to explain, because even if you start to play with your mobile phone every day from a very young age, even if you play until dark, you will not wear very thick lenses in elementary school, so most people who are very young and myopic are generally affected by their parents' genetics.

The commonly used correction methods are:

1. Get enough rest.

Don't be tired of using your eyes, use your eyes at close range for 40 minutes in a row, pay attention to looking into the distance and rest for at least 10 minutes; Combine work and rest to ensure adequate sleep!

Second, it is necessary to "pose to burn".

Don't use your eyes up close in too strong or too dark light! Don't lie down and read! Don't read in a non-static state! Such as sitting in a rickety car, walking.

Fourth, it is necessary to be "nutritious".

Pay attention to dietary nutrition, often eat Leyan vision nutrients, supplement the lutein, anthocyanins and zeaxanthin that the eyes have been consuming, and eat less sweets and fatty foods!

Fourth, it is necessary to check on time.

For adolescents with myopia, take the child to the hospital every six months for professional dilated eye refraction and long-term follow-up.

If it is pseudo-myopia, it will gradually recover, and if it is true myopia, then it will gradually control or improve the vision.
