Prevention and control of myopia in young children.
Do parents need to pay attention too early?
Children start primary school at the age of 6-7, and the intensity of eye use gradually increases, and 6-12 years old is the age group with a high incidence of myopia, and it is also a critical period.
So young children under the age of 6, since there is no academic pressure, do they not need to worry about myopia?
Let's take a look at a thought-provoking set of statistics:
As of 2020, the myopia rate of children and adolescents in China has reached 527%。
Among them, the myopia rate of 6-year-old children is 143% and 35 for elementary school students6%, and junior high school students soared to 711%, and high school students reach a staggering 805%。The total number of myopic people has exceeded 600 million, and the inflection point of myopia has dropped sharply from the original 11 years old to 6 years old, showing an obvious trend of younger age.
In the face of this grim situation, we can't help but ask: has the prevention and control of myopia in young children reached the point where it is urgent?
The answer is clearly yes.
Macro data aside, we've already mentioned that young children develop their axes faster. Under normal circumstances, physiological axial growth is balanced by changes in corneal curvature and lens. However, if myopia prevention and control is neglected during this period, causing the eye axis to exceed physiological growth, then the hyperopia reserve will be depleted prematurely.
What are the consequences of this?
Many very young children, prematurely deplete the farsightedness reserve, or even develop myopia prematurely, then the likelihood of them becoming highly myopic in the future will be greatly increased, and the possibility of an eye axis of more than 26mm in adulthood will also be greatly increased.
The harm of the long eye axis caused by high myopia is not unfamiliar to many parents, and we will not repeat it here. I just want to emphasize that the purpose of our myopia prevention and control is to enable children to control the power and eye axis within a safe range in adulthood, so as to reduce the risk of fundus lesions in their old age.
Therefore, early control and early intervention for young children are still very necessary.
