How can I prevent myopia? 10

1.Pay attention to eye hygiene.

2.Stick to eye exercises.

3.Combine work and rest, and get enough sleep.

4.Pay attention to nutrition, strengthen exercise, and enhance physical fitness.

5.Regularly go to a professional glasses company to check your vision, and if you find that the decline is found, it should be corrected in time to prevent myopia from progressing and ensure adequate sleep.

Getting enough sleep is an important factor in eliminating fatigue and restoring your ability to work. Because the eyes are in a state of sleep, the muscles are most fully relaxed, and it is most easy to eliminate fatigue, which is also essential to ensure good health. At the same time, endocrine hormones increase during sleep, which is also important for the growth and development of children and adolescents.

Therefore, parents and teachers should pay attention to students' sleep and ensure that students have sufficient rest time.

Eye Exercises Eye exercises are a self-massage method to protect the eyes according to the principles of meridians and massage theory of the motherland's medicine, combined with medical sports. 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. Practice shows that insisting on doing a good job in eye exercises is of certain significance to protect eyesight and prevent myopia.

Do this several times a day, choosing a break between studies.

Eat a reasonable diet.

Studies have found that increasing protein and decreasing carbohydrates** in the diet can reduce or stop the increase in myopia in adolescents with a genetic background who develop myopia. Therefore, to avoid the occurrence of myopia, eat less sweets 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.

Research surfaces, the prevention of myopia can be supplemented with protein, calcium, phosphorus, carrots, bean sprouts, oranges, mandarins, jujubes and other vegetables and fruits are also beneficial to the prevention of myopia.

A simple and troublesome approach, suitable for "lazy people" who are afraid of trouble and want to protect their eyes

1.When reading or working with a desk lamp, turn on the headlights in the room, and don't let the light drop be too large, which will make the eyes tired and cause myopia or myopia. Watching TV is the same with a computer.

2.Reading or working should have proper lighting, preferably from the left. Do not read or write in too dark or too bright light to reduce the burden on your eyes.

3.Eat more vegetables.

4.After playing with the computer for an hour, look at the greenery in the distance for 5 minutes.

5.When going out, try to wear tan anti-polarized sunglasses, which can not only prevent glare, but also protect your eyes from ultraviolet and blue light.

6.Blink more, don't stare at the computer screen and play games, don't even roll your eyes.

7.Tears are also protective for your eyes. (I usually watch soap operas and cry when I watch them).

Watch TV. Be careful when reading books, as well as computers. Don't look too closely. Look at it for a while and let your eyes rest for a while. Eye exercises can also be done.

Myopia is generally divided into pseudomyopia, true myopia and mixed myopia.

Pseudomyopia is relative to true myopia. True myopia is when the refractive system of the emmematic eye is at rest, that is, the far point of the eye is within a limited distance after the adjustment is removed.

In other words, myopia is caused by congenital or acquired factors that cause the anterior and posterior diameter of the eye to become longer, and parallel rays of light enter the eye and form a focal point in front of the retina, causing blurred vision.

In pseudomyopia, there is a partial adjustment when looking at distant objects. It is common in adolescent students when looking at close objects, due to the degree of use of adjustment is too strong and the duration is too long, resulting in continuous contraction of the ciliary muscle, causing adjustment tension or withering spasm, so when turning to distant after a long time of reading and writing, it can not quickly relax the adjustment, resulting in dizziness, eye swelling, vision loss and other visual fatigue symptoms. This condition of myopia due to the increased refractive power of the eye makes the eye myopia, which is called pseudomyopia.

Both pseudomyopia and true myopia have the characteristics of visual fatigue and poor distance vision and good near vision in terms of symptoms. However, pseudomyopia is a functional change, and there is no problem of the anterior and posterior diameter of the eyeball, but only to adjust spasticity, and most of them can be turned into farsightedness or emmetropia after being spotted with cycloplegic drugs. If you wear myopia lenses according to true myopia**, the eyes will feel very uncomfortable because they do not relieve the adjustment spasm, and there is even a risk of myopia development.

True myopia. True myopia: also known as axial myopia, the refractive interstitium of the refractive interstitium is normal, the anteroposterior diameter of the eye axis is extended, and distant light rays are imaged in front of the retina after entering the eye.

Mixed myopia.

Often a person's myopia is due to pseudomyopia caused by eye fatigue, resulting in the slow synchronization of part of true myopia and pseudomyopia, so to speak, in people with deepening myopia, they all belong to mixed myopia, at present, myopia is the most effective, you go to try [high dynamic glass, it can fundamentally myopia amblyopia, restore the concave lens, and eliminate the myopia caused by ciliary muscle spasm from the source! I think restoring your vision should be something you do on your own initiative, and it should be very proactive. "Opportunities will only be reserved for those who are ready", this classic success adage is believed to be known to many people.

However, we in China still have a saying called "God helps those who help themselves".

It can't be prevented. Resign yourself to the sand sculpture.

Myopia prevention refers to a method to prevent myopia by correcting posture and shortening the time. The incidence of myopia in China is still increasing day by day, and medical experts believe that the visual environment is the main cause of myopia, rather than eye habits.

The essence of myopia is that the regulatory function of the eye muscles declines, resulting in distant light passing through the refractive of the eye, and the focus falls in front of the retina, and a clear image cannot be formed on the retina. It can be seen that in order to prevent myopia, it is necessary to avoid excessive tension of the eye muscles, which leads to the decline of their regulatory function.

In junior high school, a candle was placed with a convex lens about half a meter apart, the distance was adjusted appropriately, and the image was clear, corresponding to the lens (convex lens) and retina (cardboard) of the eye.

Now, if you replace this convex lens with two convex lenses with half the original refractive power, what do you think will happen?

Okay, now this device is equivalent to the eye wearing farsighted glasses, whether it is the lens or the farsighted glasses, the ability to "refract light" is lower than that of the single convex lens, so at the same distance, the lens wearing the farsighted glasses must relax to see the object clearly, distracting the work of refracted light, thus preventing myopia.

Therefore, wearing farsighted glasses can prevent myopia.

I really wish I could get rid of unnecessary myopia.

In order to prevent the occurrence of myopia, adolescents should pay attention to the following:

Pay attention to eye hygiene. Develop good reading and writing habits: read books and write in a correct posture; Don't read when you walk in a car; After reading for a long time, pay attention to rest and relax your eyes; Look at distant objects as much as possible; Don't watch TV or use a computer for long periods of time.

Insist on doing eye exercises, etc.

Be mindful of exercise. Rational nutrition, strengthening the system, and formulating a reasonable living system. Pay attention to the intake of foods rich in vitamins A, B2, C and E, eat more liver, milk, egg yolks, green leafy vegetables, carrots and other foods, eat more coarse grains, eat less candy, limit the intake of high animal fat, and prevent the occurrence and development of myopia.

Have your vision checked regularly. Establish a vision file, find out the cause of vision loss in time, and prevent the vision from continuing to decline and form myopia.

Prevention method 1: Keep your eyes away from the book. How long?

20cm is about the same. That is, the length of a ruler. Or spread your hands apart, the distance from your little finger to your big thumb.

When reading books, I deliberately develop such a distance, and after a period of time, the habit is formed, and I unconsciously maintain this distance. And it will also prevent hunched backs.

Prevention method 2: Close your eyes. When the book is very dry and astringent, I will habitually rub my eyes or eye drops with my hands.

None of this is a good habit. At the end of a class or after reading a book for 50 minutes (or so), close your eyes and take a break. When you close your eyes, tears moisturize your eyes and play a protective role.

For eye drops, I personally think that it is a three-point poison and it is not good to rely on. Therefore, many times when you close your eyes for a few minutes after being tired, you will feel brighter when you open your eyes, because of the effect of moisturizing tears.

Prevention method 3: Look from afar. Students should not sit in the classroom all the time after class. Go out and stand for a while and look out into the distance. Looking from afar can keep your eyes relaxed and easily relieve eye strain.

Prevention method 4: Look green.

Is it true that taking more physical education classes can prevent myopia?

How can myopia be prevented? Star Awareness Project

The professor at Harvard University tells you: to prevent myopia in children, you only need to do one thing. It's that simple, can you stick to it?

Pay more attention to overuse your eyes, rest for a few minutes after using your eyes for more than half an hour each time, participate in more outdoor activities, and eat more foods rich in vitamin A.

Studies have shown that in addition to the heavy workload of schoolwork, poor classroom lighting is one of the main causes of students' vision loss, so it is important to choose a high-quality lighting environment in the classroom!! Improve the lighting environment of primary and secondary school classrooms and effectively prevent myopia!!

1. When reading and writing, do not lie on the table and tilt your head to study, let alone lie down or sit in the car to read, and the posture of reading and writing must be correct.

Don't lie on the table when reading and writing, and don't lie down to read and write. When writing, the distance between the body and the body should be about 30 cm, and do not use the eyes for a long time. Especially when watching TV on the computer, don't watch TV for more than 40 minutes.

Take timely rest. Do eye exercises for 10 minutes, look at the green scenery in the distance or close your eyes to rest.

The posture of the word should be correct, and the myopic eye should pay more attention to the time of reading and writing not too long, generally about 40 minutes, should stop and rest for 10 minutes, look into the distance or move to look again, and at the same time pay attention to the posture of writing to be correct, so that reading must sit, writing must be correct.

2. Limit the use of computers and mobile phones, and watch electricity every day.

Hello, prevention of myopia first, wear the right glasses. It is wrong to wear glasses to get deeper and deeper, and wearing the right glasses so that children can see objects clearly is an important way to effectively prevent the development of myopia. Second, do more outdoor sports.

Thirdly, people with conditions can wear orthokeratology lenses under the guidance of a doctor.

Hello experts pointed out that two hours of outdoor exercise every day can reduce the incidence of myopia and further deepen it to a limited extent. Of course, table tennis and badminton will improve children's eye adjustment ability, and to a certain extent, it will also slow down the progression of myopia. Therefore, it is okay to exercise more, pay attention to reading and writing posture, pay attention to eye habits, do eye exercises and play less with electronic products.

Try not to look at the computer, mobile phone, look at the distance more, and do eye exercises often.

Improving the lighting environment in primary and secondary classrooms... Effective prevention of myopia...

1. Pay attention to eye habits, use eyes scientifically, use eyes reasonably, 2. Check and do glasses health exercises.

3. Combine work and rest, and get enough sleep.

4. Supplement nutrition and strengthen exercise.

5. Regularly go to a professional hospital for vision testing.

Change bad habits, spend about 4 hours a day outdoors, try not to use electronic products too much or in a dark environment, and eat less sweets.

How can myopia be prevented? Star Awareness Project

1 in 3 children is nearsighted, don't let your child be that one!

There are two types of prevention and control of myopia:

Clause. 1. People without myopia should prevent the formation of myopia, and after having myopia, it is necessary to prevent myopia from progressing too quickly and forming pathological myopia with eye lesions. For people who are not myopic and have myopia, the prevention at this time requires the child to pay attention to eye hygiene, try to have regular work and rest time, and control the time of looking close, such as the time of watching electronic products, taking a break of 10-20 minutes for half an hour, and controlling the time of looking at nearness.

It is necessary to carry out regular physical exercise and outdoor activities, especially physical exercise and outdoor activities are the best means for children and adolescents to prevent myopia.

Clause. 2. If myopia has occurred, it is necessary to prevent myopia from becoming pathological myopia, and to be cautious or myopia progresses too quickly.

1. Sports and outdoor activities. Clause.

2. Wearing orthokeratology lenses can also delay the occurrence of myopia by wearing orthokeratology lenses. If you don't wear orthokeratology lenses, you can also wear progressive multifocal glasses, which can also prevent socks from progressing too quickly.

Acts of life. 1. Plenty of light.

The light should be sufficient and comfortable (if the light is too weak and the font is not clear, the more you look at it, the more you will become short-sighted).

2. Reflections should be avoided.

Desks should have side light fixtures designed to reduce reflections and reduce damage to the eyes.

3. Don't read for too long.

Whether you're doing homework or watching TV, don't spend too much time and take a break every hour or so.

4. Sit in a correct posture.

Do not hunch over, lean very close or lie on your stomach to do homework, which is easy to cause excessive tension of the ciliary muscles and cause fatigue, and then cause myopia.

5. The reading distance should be moderate.

The standard distance between books and eyes should be 30 cm, and the height of tables and chairs should also be suitable for the body.
