What is the child's farsightedness reserve?
Does insufficient reserves mean myopia?
Can the child's depleted farsightedness reserve be replenished?
What is the Farsightedness Reserve?
In general, newborns have small eyeballs, immature eyes, short eye length (eye axis), and are in a state of farsightedness!Then, with the growth and development, the diameter length of the anterior and posterior eyeballs will gradually become longer, the farsightedness reserve will gradually disappear, and the vision will slowly transition from farsightedness to emmetropia, and generally reach the state of emmetropia around the age of 12.
The child's vision will go through the stage of [farsightedness-normal-myopia], and what is consumed in the process of development is [farsightedness reserve]!
The farsightedness reserve is like a "piggy bank" for the eye, which protects the eye from myopia. But if we don't pay attention to protection, there will be less and less of this "piggy bank".
The amount of farsightedness reserve is an important indicator to determine whether a child has myopia. With the advancement of science and technology, people's lifestyles have changed dramatically. Children and adolescents use their eyes for a long time, have a heavy load, rely excessively on various electronic products, and have fewer and fewer outdoor activities, which leads to the premature depletion of children's farsightedness reserves in the long run, and ultimately leads to the high incidence of myopia in children at a young age.
The misconception of farsighted reserves.
The more farsightedness reserves the better
If there is too much farsightedness reserve and the eyes are overly self-regulated, there will be a situation where it is not clear to see near and far, or even amblyopia.
Insufficient reserve of farsightedness ≠ myopia
The rapid depletion of farsightedness reserves only increases the risk of myopia, not that it is already myopia!At this time, it is necessary to pay attention to the child's vision problem, delay the depletion rate of farsightedness reserves, and do not need to rush to the fire!
The child's farsightedness reserve is reduced, can it be replaced?
The decrease in the reserve of hyperopia is marked by the growth of the eye axis.
Theoretically, the eyeball has become longer and cannot be retracted. The farsightedness reserve that has been reduced may not be easy to get back.
However, it is not too late to make amends, adjust the child's lifestyle and state in time, conform to the characteristics of the child's visual function development, and do not let the child's visual burden overwhelm his immature visual system. Parents should pay attention to:
Increase your child's time outdoors
Outdoor exercise is the best way to prevent excessive depletion of hyperopia reserves, and more than two hours of outdoor activities a day can effectively delay the depletion of hyperopia reserves.
Cultivate good eye habits in children
Parents should always check the indoor light to provide children with a well-lit eye environment, which can also delay children's visual fatigue when doing homework.
Supervise the child's reasonable use of eyes, no more than 30 minutes of reading and homework at a time, and rest for 10 minutes every 30 minutes, looking away or closing his eyes to rest.
Do not let your child lie down or read on his stomach, sit in a correct posture and follow it"One inch, one foot, one punch"of the original".
Guide your child to develop good eating habits
Ensure that the nutrition is balanced and not picky eaters. Eat more fruits and vegetables and reduce sugar intake.
Establish a profile of your child's refractive development
Based on this, we can understand the development trend of children's refractive status, achieve early warning and early detection, and then use effective myopia prevention and control measures.
