How myopia is practiced. How to become myopic

The causes of myopia are:

1. Myopia is mainly due to long-term excessive use of the eyes, so that the muscles inside and outside the eyes are in a tense state for a long time and cannot be rested, and over time the eye axis becomes longer, and the objects cannot converge on the retina, and the distant objects cannot be seen clearly.

Second, the adolescent body is still developing, and the eye axis is also constantly developing, so that the anterior and posterior diameter of the eyeball increases, resulting in an increase in myopia.

Third, the causes of myopia have not been avoided, which is also the reason for the increase in myopia.

Fourth, teenagers have a strong ability to adjust their eyes, and if they do not have formal medical optometry, the prescription of the glasses they wear is likely to be higher than the actual one, which will cause visual fatigue and cause myopia to become more and more serious.

5. Bad eye habits can also cause vision loss, especially the use of electronic products, which makes teenagers overuse their eyes.

6. It is recommended that if the prescription is more than 300, it should be worn frequently, which will help correct myopia and relieve eye fatigue. If the myopia is within 300 degrees, you can wear it when needed.

Nowadays, myopia is becoming more and more common, and it is getting younger and younger. Children's myopia not only seriously affects life and learning, but also makes parents worried. Children under the age of 18 are short-sighted, it is recommended to take Leyan Vision Nutrients, two packs a day, you can see significant changes in 7 days, and if you insist on taking it for a period of time, the myopia will be reduced and your vision will be restored.

One blindly follows the trend; Both are self-cultivated.

Fall asleep and read a book, turn off the lights and play with your phone, and watch TV within half a meter.

Causes of myopia.

The causes of myopia are complex, and there are many influencing factors, and the main factors are roughly divided into genetic factors, environmental factors and nutritional factors.

1.Genetic factors: According to a large number of survey data, the consensus conclusion is that high myopia is related to heredity, and there is a large difference between moderate myopia and less than moderate myopia.

The genetic type of high myopia is concluded by most survey data to be autosomal recessive. As a result, parents and offspring may not develop myopia at the same time. Heredity is often influenced by the objective environment, that is, the conditions of life, which makes it mutate, which increases the complexity of heredity.

2.Environmental factors: environmental factors are mainly close operation and poor working environment, which is the oldest theory, although there are still some controversies, but from a large number of domestic and foreign relevant research reports, it has been recognized that heredity and environment are the main reasons for the formation of myopia, and pointed out that environmental conditions are the objective factors that determine the formation of myopia.

1) Adjustment theory: The vast majority of myopia appears in adolescence, because the adjustment power of adolescent eyes is particularly strong, and they have a high degree of adaptability to work and study at close range, so they are not easy to get tired when they see close. However, if the ciliary muscle is over-tensed for a long time, the ciliary muscle will be fatigued or even spasm and accommodative myopia will appear, and if it is not eliminated in time, it can become irreversible true myopia.

or by other means affecting the elongation of the eyeball axis.

2) Divergence theory: When using the adjustment of close work, it is also necessary to strengthen the divergence function of both eyes turning inward at the same time, which can lead to the pressure of the eye muscle on the eyeball, which can cause the extension of the eye axis.

3) Environmental adaptation theory: In early childhood, the eyeballs are small, most of them are farsighted, and with the increase of age, the eyeballs increase to the state of emmetropia. Reading too much near up during this developmental process makes the eye myopic in order to adapt to this need for accommodation.

This theory has been opposed by many people, but it is a consensus that it is very malleable during the developmental period and has an important impact on the development of myopia.

It is worth mentioning that external factors such as lighting, reading posture, contrast, small and blurry characters, too close proximity and long reading time can all affect the role of these factors.

3.Nutritional constitution theory: From some data analysis, the deficiency of trace elements such as cadmium, strontium and zinc and the weakness of physical constitution can also affect the occurrence of myopia, but there are different ways through which these factors affect myopia.

In short, it can be seen from the above that myopia can be caused by many factors, both external factors and internal physical factors, rather than a single factor.

Lying down and reading a book, especially the worse the light, staring at the computer, watching TV.

Just use your eyes up close for a long time!

Hello, myopia is irreversible but its development can be prevented, and here are several ways to introduce you:

1. Wearing orthokeratology lenses, you can wear them every night and take them off during the day, and change the shape of the corneal surface through physical action, so as to control the development of myopia! Normal vision will be maintained during the day. The progression of myopia can be effectively controlled! Our hospital is clinically proven and the results are very good.

2. Wear rigid contact lenses, wear them during the day and take them off at night, which is suitable for people with high astigmatism and can also effectively control the development of myopia.

3. Use Metro eye drops every night, once a day, to relax ciliary muscle tension, relieve visual fatigue, and delay the development of myopia.

4. Use virtual focus glasses, read and write or look at the computer and other near use, wear them several times a day, to reduce the adjustment of near looks, so that children's eyes can be as easy as looking at distant scenery when looking at near places, and avoid aggravating the development of myopia with eyes at close range for a long time.

5. Usually use the goggles regularly to increase the blood of the eye muscles**, and at the same time relax the excessive adjustment function of the ciliary muscles and relieve visual fatigue.

6. Oral Lejing, 1-2 tablets once a day, is used to supplement various vitamins and trace elements necessary for eye development, and at the same time supplement the necessary antioxidants for the eyes to prevent the development of myopia.

Commonly used computers make the background or blank space of the computer light green, just want to know the green of the interface, which is good for the eyes.

After a long time, the computer stands up and moves the cervical spine, stands at the window and looks into the distance, if there is no condition, close your eyes, and the clip of the prairie in your mind can also have the same effect.

General eye exercises can play a certain role, and there is also a way to open the eyes normally, and then open them widely, it is the eyeballs that are forced, not the eyelids, and a group of ten times is repeated. Doing a set of 2 hours also improved.

There should be no problem.

First of all, it is necessary to analyze whether the burden on your eyes is very heavy, such as what you often have to read and study, if the burden is not heavy, then congratulations, life is much better.

First of all, ensure adequate sleep and good work habits, so that the eyes and body can get sufficient rest, and create prerequisites for restoring vision;

Secondly, supplement more necessary nutrients, such as eating more eye-catching foods, such as carrots, wolfberries, etc., and doing more eye exercises to help eyes rest and recover;

Again, it is an auxiliary**, I have used a good vision eye patch before, it is the kind advertised by the radio station, it is said that it is dedicated to the national shooting team, made of pure Chinese medicine, there is nothing ***, it will feel different after using it, there should be a flying pattern after a month, and the sight will be clearer, but if it is more expensive according to the course of treatment, a course of treatment will be more than 500, it will take about a month, and the recovery depends on the situation, generally three courses of treatment, if the situation is good, two can also be.

In addition, I would like to suggest by the way, you have to adapt to exercising more, which will also be good for your eyesight, hehe, I used to play basketball, and I was troubled to wear glasses, but I also took these, and the effect was good.

Of course, you can also go to the hospital for surgery, and you can get it in a thousand, but it is not so reassuring to go for surgery only when you have to do it.

At your current age, the general prescription will not increase much, sometimes you may have eye fatigue before you go to check the prescription, and you may not seriously help you insert the film, but you can go to a regular hospital to check, wear glasses to your naked eye vision does not affect daily life shall prevail, if you usually do not do fine and far operations, you can slowly adapt, if it affects daily life, you need to bring glasses.

Whether it can be recovered depends on whether it is true myopia or pseudomyopia. If it is true myopia, then it cannot be recovered, but can only be corrected, controlled or improved. If it is pseudomyopia, then through correction, it can be gradually recovered.

General suggestions: 1. The time of close eye use should not be too long, and every 40-50 minutes should be a little rest for 3-5 minutes, and looking into the distance will slow down visual fatigue.

2. Read and write, play with the computer, maintain a correct posture, the height of the table and chair should be appropriate, and the distance between the eyes and the reading materials should be about 33 cm.

3. Mix whole grains, meat and vegetables, eat more vegetables and fruits, and don't eat partially. Lack of vitamins in food is prone to night blindness and dry eye disease, and lack of trace elements chromium and calcium in food makes it easy to suffer from myopia. In addition, it is also necessary to pay attention to regular supplementation of eye vision nutrients, not from the nutrients required by the eyes, enhance the anti-fatigue ability of the eyes, and better protect the eyesight.

Fourth, when reading and writing, the light should be moderate, not too strong or too dark, and the light should come from the left front, so as not to obstruct the vision of the hand shadow. The light should be soft, if it is incandescent, it should be between 25 and 40W, and it is not recommended to read in the sun. Because the intensity of light has a direct impact on pupil dilation, too strong light will increase the intensity of eye accommodation, aggravate the intensity of eye labor, and it is easy to cause myopia after a long time.

Generally, desktop lamps should be less than 40 watts.

5. Avoid reading while walking or reading in a walking car. Because the carriage is shaking, the body is shaking, and the distance between the eyes and the book cannot be fixed, the burden on the glasses will increase. Often, this is likely to lead to myopia.

6. Actively participate in physical exercise to enhance physical fitness. As the eyeball follows the target, the ciliary muscles continue to relax and contract, and the synergistic effect of the extraocular muscles can increase the blood perfusion of the eye, promote the metabolism of the eye, and thus reduce eye fatigue. Moreover, the quality of physical fitness is also closely related to the occurrence of myopia in children.

Malnourished and weak children are prone to myopia.

7. Insist on doing proper eye exercises. By massaging the acupuncture points around the eyes to enhance the blood circulation of the eye socket, improve neuronutrition, eliminate the excessive congestion in the eye, and achieve the purpose of relieving eye fatigue, it is conducive to the prevention and treatment of pseudomyopia in adolescents, and is a good way for adolescents to self-care their eyes.

8. Eat less candy and high-sugar foods. Too much sugar will produce a large amount of acidic substances in the blood, and the acid will combine with the salt in the body, especially calcium, resulting in a decrease in blood calcium, which will affect the toughness of the eye wall, make the eye axis easy to elongate, and promote the occurrence and development of myopia.

Commonly used methods to correct myopia are:

1. The eyes should not be overworked to maintain sufficient sleep, and it is best to wear glasses and do correction to prevent further deterioration.

2. Insist on doing eye exercises every day and massaging relevant acupuncture points to relieve eye fatigue.

3. When looking at the computer, often blink actively, because people's eyes will not blink automatically in front of the computer screen, resulting in dry eyes.

4. Take a 10-minute break every time you use the computer or work in close proximity for 1 hour to relieve visual fatigue.

5. Rest more, sleep also has an impact.

Those under the age of age should take vision nutrients in a timely manner. It is recommended to take two packets of Joyeye Vision Nutrients every day, and insist on taking it for a period of time, the degree of myopia will be reduced, and the vision will be improved.

Once you have true myopia, it is unlikely that your vision will be restored. The only way to do so is to slow down the progression of myopia, or to stop it. For example, 200 degrees of myopia, whether you can remove 200 degrees is unlikely, you can only let 200 degrees of myopia not develop deeply, or the child after many years of 200 degrees of myopia do not change, can not be deepened, can only play these roles.

There are currently two approaches that can be taken, especially for teenagers:

1. Reduce the time of working in close proximity, learning at close distance, and looking at electronic products;

2. Be sure to participate in more sports outdoors and exercise more in nature;

3. You can try to let your child wear orthokeratology lenses to reduce the further development of myopia.

Ways to recover your eyes after myopia surgery:

1. Don't"Keep your eyes peeled"Blinking frequently can reduce the amount of time your eyes are exposed to air and prevent tears from evaporating.

2. Don't blow the air conditioner for too long, avoid air flow blowing through the seat, and place tea near the seat to increase the humidity around the seat.

3. Eat more fruits, especially citrus fruits, and also eat more green vegetables, grains, fish and eggs. Drinking plenty of water can also help reduce dry eyes.

4. Maintain good living habits, get enough sleep, and don't stay up late.

5. Avoid continuous operation of the computer for a long time, pay attention to the rest in the middle, usually 1 hour of continuous operation, 5-10 minutes of rest. When resting, you can look into the distance or do eye exercises.

6. Maintain a good working posture. Maintaining an optimal posture with both eyes at eye level or slightly downward at the phosphor screen will ease the neck muscles and minimize the area of the eyeball exposed to air.

7. Adjust the distance of the phosphor screen. The recommended distance is 50-70 cm, while the phosphor screen should be slightly 10-20 cm below the eye level, with a downward viewing angle of 15-20 degrees. Because the angle and distance can reduce the need for refraction, the chance of eye fatigue is reduced.

It is recommended to reduce the time of playing with mobile phones after myopia surgery, myopia surgery is not a real ** myopia eye, just correction, if you do not pay attention to the eyes after surgery, the myopia degree will still increase, and finally the consequences of myopia can not be avoided.
