Abstract: there is no strict correlation between the degree of myopia and true and false myopia. High degree may also be false myopia. Similarly, low degree may also be true myopia. After myopia, it is necessary to distinguish “true and false”.
nowadays, more and more children suffer from myopia, and some babies even wear glasses before they go to primary school. The incidence rate of primary school myopia in China is 22.78%, according to ancient Chinese literature search. There are too many reasons. Today, let’s catch the seven “sins” of our parents. In addition to allowing our baby to use less electronic products, it’s more important that we don’t do anything that damages our eyes.
1. Take a nap to eliminate eye fatigue
some parents think that it doesn’t matter if the baby uses his eyes longer at ordinary times. If his eyes are tired, he can eliminate visual fatigue as long as he sleeps at night. In fact, sleeping can not completely relieve eye fatigue. To reduce the pressure of using eyes, children should be taught to relax their eyes during long-term intervals. They can focus on distant objects, look up, turn their eyes left and right, etc. Here to remind parents that although looking at a distance can alleviate eye fatigue, the key is not to look at how far, but to shorten the time of using eyes at close distance each time.
2. False myopia does not need to be corrected. There is no strict correlation between the degree of
myopia and true and false myopia. High degree may also be false myopia. Similarly, low degree may also be true myopia. After myopia, it is necessary to distinguish “true and false”. If false myopia is mistaken for true, wearing myopia glasses directly will “make it true”; However, if it is determined to be true myopia after diagnosis by a doctor, it must be corrected in time.
pseudomyopia refers to the ciliary muscle around the lens of the eye, which is specially responsible for the adjustment of focal length, such as looking far or near. When the eyeball is overused, it produces spasm and can not relax, resulting in the phenomenon of “myopia”, but if it is rested, the vision will return to normal. Pseudomyopia is functional, caused by accommodation spasm, and the ocular axis is normal. It is more common in children and adolescents with younger age, shorter onset time and lower diopter. Pseudomyopia should not wear myopia glasses. It can return to normal after rest and appropriate treatment.
true myopia is due to the lack of eye hygiene, which makes the eye axis longer, so that after the parallel light enters the eye, the focus falls in front of the retina and can not image clearly. True myopia is organic, which is determined by axial elongation and corneal curvature, and has no obvious relationship with adjustment. It is more common in adolescents with older age, longer onset time and higher diopter. True myopia should be corrected by wearing myopia glasses.
3. Do not wear glasses for children with myopia
some parents insist on not wearing glasses for children, thinking that once children are used to wearing glasses, they can’t take them off, or that wearing glasses too early will lead to the deepening of children’s degree. This idea is wrong. There are two main reasons for the deepening of
: one is pathological myopia. This is an internal lesion of the eye, which is hereditary. It shows that myopia continues to deepen and increases rapidly. If the degree of myopia increases by more than 100 degrees or even more than 200 degrees within a year, or the accumulated high myopia reaches 2000 degrees, it is likely to be pathological myopia. Another reason is not paying attention to eye hygiene and incorrect eye habits. This reason is more common. Therefore, the deepening of eye degree is not due to wearing glasses. Generally speaking, after optometry by ophthalmologists and wearing glasses with appropriate degrees, the continuous deepening of degrees can be avoided.
some parents take a compromise approach to let their children wear glasses occasionally. For example, they don’t wear glasses in daily activities. They only wear glasses when they can’t see the blackboard clearly in class, when they do their homework and read books. This approach is easy to cause children’s learning disabilities, and develop the bad habit of squinting because they can’t see clearly. On the contrary, it is easy to lead to the increase of myopia.
4. Turn the table lamp light to the brightest
many parents know that too dark light will affect their children’s vision, so when purchasing table lamps, they often unilaterally pursue the brightness of the light. They think that the brighter the light is, the better their children’s vision will be. They will also turn the light to the brightest when using table lamps at ordinary times, In fact, dim light and too bright light are bad for children’s eyes. Too bright light is also one of the sources of visual fatigue. Long term use will affect the normal development of children’s vision. When reading closely, just keep the light bulb brightness of 60-100 watts. When reading and using the computer, you should avoid dazzling desk lamps directly into your eyes and maintain soft light.
5. Choose “eye protection lamp”
to protect eyesight. Some parents choose “eye protection lamp” to protect eyesight when buying desk lamps for their children. Eye protection lamps are also called “high-frequency eye protection lamps”, which can protect the eyes better than ordinary fluorescent lamps. However, the eye protection lamps sold on the market are not without stroboscopic, but the frequency of stroboscopic is very high, which can not be distinguished by human eyes, so it feels like there is no stroboscopic. The light from the eye protection lamp is still discontinuous, with one on and one off. Reading under this eye protection lamp for a long time will also be tired. The light of some eye protection lamps is too bright, but it will damage the eyes and deepen myopia. It is suggested that parents choose traditional incandescent lamps for their babies. Incandescent lamps have yellow light, which is relatively soft. Because there is no interference of AC, the light is relatively stable.
6. Turn on the night light when the baby is sleeping
many mothers turn on a night light when the baby is sleeping to take care of the baby at night. In fact, turning on the light to sleep is equal to giving children artificial light, which will inhibit the secretion of melatonin and affect children’s growth and development. According to the research of some scientists, people disturbed by artificial light have a higher probability of cancer than normal people. Because the reduced secretion of melatonin can not protect normal cells from damage, cell variation or cancer cell proliferation may occur. Therefore, children can’t turn on the lights when they sleep at night.
but children may be afraid of the dark when they are 1-2 years old. Therefore, when they want to go to sleep at night, they can use the dark night light and turn off the light when they fall asleep. They must form a good habit of turning off the light and sleeping.
7. Supplement children with excessive vitamin a
appropriate vitamin A supplementation can make people say goodbye to the trouble of eye fatigue, but eating more is not beneficial. In particular, infants and young children are particularly sensitive to excessive vitamin A. taking a large amount of vitamin A in a short time is very prone to acute poisoning, which is manifested as increased intracranial pressure, hydrocephalus or pseudobrain tumor, irritability, convulsion and vomiting, and severe cases can die. In children with long-term over limited intake of vitamin A, the epiphysis will close in advance, resulting in low growth, fever, headache, vomiting, abdominal pain, loss of appetite, hemolysis, anemia and other symptoms.
it is a safe and effective way to take nutrients from food to protect eyes. For example, animal foods such as liver, carrot, milk, egg yolk, spinach and other foods are good choices.
8. Let children use mobile phones and iPads a lot.
parents love to play with mobile phones. With them, children will learn to play. Sometimes the most effective way for parents to deal with their children’s crying is to play with mobile phones and iPads.
mobile phone screens emit two kinds of harmful light – high-energy short wave blue ray and ultraviolet ray. Long term exposure to these two kinds of light can cause eye problems such as myopia, amblyopia and astigmatism, as well as glaucoma, cataract and even blindness. 0-8 years old is the peak of children’s development, and during this period, the retina is also the weakest, and the harm caused is irreversible.
