Nowadays, of child myopia increasing, not long ago, beijing health bureau releases ” Beijing 2010 year sanitation and report of crowd health state ” show, the child that wears glasses already exceeded most probably. So ” small glasses ” exceed most probably besides the child undesirable have a few reasons of strange stage with the habit such as the eye? The expert points out, this may want ” date from ” on the food when be pregnant to mom. Contemporary diet structure decides pregnant woman absorbed overmuch beverage and flour and rice, bring about the candy inside body cent is exorbitant, fetal crystal is premature development, bring about myopia more easily.
No matter you are much old age, the likelihood has such impression: Opposite now more and more ” small glasses ” , ten years ago even the myopia a few years ago should be gotten less much. Photograph adjacent the difference of myopia of two acting people is such big. Contemporary diet structure decides pregnant woman absorbed overmuch beverage and flour and rice, bring about the candy inside body cent is exorbitant, fetal crystal is premature development, bring about myopia more easily.
Candy cent brings about fetal crystal too much overgrown
Nowadays, because standard of living rises ceaselessly, the dietary structure of people is more and more elaborate, absorbed flour and rice is increasing, among them candy cent is increasing. Well-known, the development that much candy cross-eye eyeball has absorbed inside body is adverse.
From the analysis on nutrient composition, normal to person will tell, absorb overmuch candy to divide, may cause the candy inside body to divide accumulation, and when candy cent is metabolic inside body, need many vitamin, because because use up,this vitamin is met,pass big and insufficient. And eye ministry inspects cellular growth to also need many vitamin to participate in likewise.
More such to pregnant woman, if absorb candy cent is overmuch, can bring about crystal development environment unusual, eye axis growth is too rapid, accelerate myopia happening. Animal experiment makes clear, let experimental animal had absorbed polysaccharide to divide, influential to their eyesight.
The infant has unripe rational and far-sighted process
The expert expresses, children is born to be able to have certain long sight, this is the normal procedure of eye development, call physiology sex long sight.
Because infantile eyeball is smaller than growing up, the infantile eyeball size of 6 months is equivalent to adult 2/3 only, its eye wheelbase leaves more full-fledged normal eye short still, so video meeting figuration is after retina, form physiology sex long sight. Be born from the child, children eyeball growth is most rapid, eye diopter also moves to myopic direction gradually, far-sighted rate falls slowly subsequently. Exceed normal range, it is unusual or pathology sex is far-sighted. And the growth as children age, focal reach, presbyopic transfer to face up to an eye gradually.
Candy is divided but ” eat off ” fetal and far-sighted time
The sweetmeat effect to myopia cannot be ignored.
Children can divide for the process of myopia from presbyopic development for the following measure: Physiology sex long sight, face up to, myopic. Normal value is in about 3~4 year old far-sighted 200 degrees of less than, 4~5 year old far-sighted 150 degrees of less than, 6~8 year old far-sighted 100 degrees of less than, and present children myopia is overmuch, overmuch candy is absorbed to divide when likelihood and matrix are pregnant, bring about children crystal development to be concerned prematurely. Circumstance of children eye eyesight is close to an adult prematurely to change, the likelihood makes them direct ” jump over ” physiology sex is far-sighted, be born to face up to an eye namely, so shortened the time that grows myopia, myopic children also began to increase.
Sugar is contained in flour and rice, beverage component is high
Why the myopia of parental generation is less, expert analysis says, this is not coincidence. The age is in the likelihood 40~50 year old the person has such memory, bend over in by Lilliputian book reads with flashlight in the nest, but the person of that time is rare however and myopic. Can be now below the protection of the lamp that shield an eye, radiation-proof screen, myopic child is added only however many. This may be concerned with dietary structure.
As standard of living rise, our food is in more and more careful the rate that change, coarse food grain is being replaced by place of flour and rice gradually, food of a few high in syrup is walking into our table insensibly. Wait like face of rice of beverage, essence, choice. Although mouthfeel is pretty good, but it is with rice of essence of life exemple, in the process of treatment, one layer upon layer exuviate also can cause the prediction of a person’s luck in a given year of the vitamin. When treatment is rice of essence of life, beneficial to eye development vitamin already place remnant very few.
