In recent years, the age of myopia in mainland China has also begun to show a trend of younger age, and the degree of myopia in patients will become higher year by year. Many parents are also deeply worried: why do children's myopia deepen so quickly?
According to the World Health Organization's 2017 research report, the total number of myopia patients in China has reached 600 million, the myopia rate of high school students and college students has exceeded 70%, and the myopia rate of primary school students is close to 40%, and the degree has shown an upward trend.
Some people say that it is the child sitting incorrectly, the child who is addicted to electronic products, the child who has a heavy schoolwork and excessive use of his eyes... Wait a minute. But in addition to these possibilities, parents may also overlook an important thing - taking their children to optometry regularly.
Now there are many stores free optometry, but it is still not uncommon for doctors to avoid diseases, there are always customers holding "after optometry and then sell me lenses, but also said that children have such and such problems, hate to die, do not participate in not participating in" such a mentality to face optometry, but in the market is more and more standardized today, Xiaoya pro-testing This situation is very rare, therefore, we should also change the attitude towards optometry, with the right mentality to face the optometry problem.
What is the use of optometry?
Prevent myopia!
In real life, most families do not deliberately take their children to optometry, which does not mean that refraction is not important, and refraction is definitely not a trivial matter! It has important and far-reaching significance for preventing myopia problems in children and for identifying the real causes of myopia in children.
What is refraction?
Full refraction is like this!
Before understanding refraction, everyone thought that refraction was to see how many degrees of myopia there were. It was not until I came into contact with the optometry industry later that I learned that refraction is not as simple as imagined. People who have worn glasses have a deep understanding that optometry is probably the longest-consuming project in the process of dispensing glasses. So, every time the refraction is tested for so long, what exactly is the optometrist testing?
Simply put, optometry mainly examines these five items: refraction, image fusion, aggregation and dispersion, adjustment, and eye movement.
Let's take a brief look.
Refractive
We are more familiar with refractive light, and we often say that refractive error is that there is a problem with refractive light. The most direct feeling of refractive error patients is that they can't see things clearly without glasses, which includes myopia, farsightedness and astigmatism.
Fusion
Normal people are two eyes at the same time to see things, respectively, to receive the outside information transmitted to the brain, the brain after receiving two similar and slightly different two images, the two images fused into a larger, finer, and three-dimensional three-dimensional image, this is the fusion image. Healthy fusion is the guarantee of high-quality visual effects, and if there is a problem with the fusion image, it will appear:
See things ghosted, one object becomes two objects;
Only one glance can see the target;
Lack of three-dimensional perception of things, unable to accurately judge the distance of space; such as driving easy rear-end, can not accurately get the cup on the table in front, and even can not engage in carving work, can not wear needles;
Gathering and dispersing
In order to ensure that at the same time, the eyes can quickly gaze at the same target and receive the same image, and the eyes always maintain synchronous movement: synchronous internal rotation (cockfighting eye), synchronous separation. If this synchronization relationship cannot be maintained or destroyed, it may lead to strabismus, amblyopia, inhibition, deepening myopia, eye fatigue, etc.
regulate
The eye is like a camera, and it needs to adjust the length of its own lens (lens contraction) to see clear objects near and far. Sometimes because the lens is too long (the lens becomes convex) due to excessive use of the eyes, it cannot be restored temporarily, which will cause false myopia; sometimes the lens retracts slowly, resulting in a book in the near distance suddenly looking at the blackboard in the distance, and it takes a while to slow down to see clearly.
The better the amplitude and response of the adjustment function, the more the eye can resist the high intensity of the close-up eye load and the occurrence of myopia.
Eye movements
There are three main types of eye movements: gaze, glance, and follow. Normal people's eyeballs can not only rotate freely, but also can always stare at the moving target until they can see it clearly.
These five functions complement each other, involving the whole body, and any problem in any place will lead to eye discomfort. If you take your child to an optometry on a regular basis, you may be able to avoid these eye problems to some extent.
Kids these moves
You have to pay attention!
In addition to taking children to optometry regularly, in order to prevent children from being nearsighted or deepening their myopia, some small details in life also need attention.
Squint frequently
In order to see objects clearly, myopic patients have the habit of habitual squinting, this is because the eyelids can cover part of the pupil when squinting, which can reduce the scattering of light, so that it can temporarily improve and improve vision, if this is the case for a long time, it is bound to affect the child's vision.
Frequent frowns
Frequent frowning is also a habitual manifestation of some myopia patients in order to see things clearly, but frequent frowning will make the extraocular muscles compress the eyeball, which will accelerate the development of myopia.
strabismus
Some children with myopia will also have strabismus. If one eye of the child looks forward, the other eye will involuntarily develop the habit of looking outward, which is also most likely a signal of myopia.
blink
Blinking is to relieve eye stress and enhance vision. But if it is a frequent blink of an eye, it may be a sign of myopia.
In the above situation, parents are best to take their children to an optometry test so as not to cause the child's degree to continue to deepen.
