Usually in the consultation, many parents will ask about the "farsighted reserve". It is estimated that most parents have heard of this word, but do not understand what exactly the farsighted reserve is? I don't know what it has to do with myopia in children.
So what is a farsighted reserve? When the child is just born, the eyeball development is not yet complete, and most people have a short eye length (that is, the eye axis), which is manifested as "farsightedness", which is what we often call "farsighted reserve".
So what does the reserve of farsightedness have to do with myopia?
Farsighted reserves are like giving everyone a passbook with a sum of money in it, and the money represents the amount of "farsighted reserves." As the child grows older, the eye axis and vision will continue to develop, the eye axis will gradually become longer, and the degree of farsightedness will continue to be consumed until the consumption is 0, reaching the balance of payments (normal eye axis), which is normal vision. If you are under-stockpiled and overdrawn (the eye axis is too long) in the process, you will make your child appear myopia prematurely!
For example, the average "farsighted reserve value" of 5-year-old children is 200 degrees, while the "farsighted reserve value" of some children is only 50 degrees. When the eye axis gradually lengthens with development, he can consume very little "farsighted reserve", and the eye axis may continue to develop in the direction of "myopia" after the face is squarely faced.
Seeing this, some parents will feel that the more farsighted reserves, the better. In fact, no, first of all, the farsighted reserve is innate, and the degree of the eye at birth, it generally can not be increased, parents can do is to reduce the "farsighted reserve" consumption rate.
Secondly, when the degree of farsightedness is too large, beyond the scope of their own ability to regulate, it will also cause children to see far and near are not clear, for children, this condition may affect the normal development of vision, resulting in amblyopia.
So, once the farsighted reserve value is over-consumed, does it mean myopia? Nor is it. This situation can only be said that the child's risk of myopia has increased, but it does not mean that the child is necessarily myopic. Just like each child's height development is early and late, each person's rate of hyperopia reserve consumption at different ages is not the same, which requires comprehensive judgment based on vision, eye axis, corneal curvature and so on.
Normally, 6-year-olds also have a reserve of farsightedness between 75 and 125 degrees. Statistics have found that at age 6, if the eye diopter is still 75 degrees, then the risk of myopia in the future will be reduced, and conversely, if it is below 75 degrees of hyperopia, the risk of myopia is increased. At this time, parents need to pay attention, but there is no need for excessive anxiety. Just pay attention to the child's eye habits and observe them regularly.
So, how can we maintain a good reserve of farsightedness?
In addition to protecting the baby's vision, it is necessary to "spend less money", that is, to reduce the time spent playing mobile phones and watching TV, and more importantly, to "save more money", so how to do it?
For children aged 0-3 years, first of all, some eye diseases that may affect the development of children's vision should be checked, such as congenital cataracts, strabismus, etc.
Establish eye health profiles for children: 3-year-olds can learn to check their eyesight, and then begin to build eye health profiles, and maintain regular check-ups every six months or a year.
The most important thing is to develop good eye habits.
Outdoor activities are a key measure to delay eye myopia, parents should try to ensure that children have 2 hours of outdoor activities every day, at least 10 hours of outdoor activities per week, stay for 1 hour more, the probability of myopia will be reduced by 2%.
For children who have already gone to school, parents can use the time to go to school and after school to let their children walk as much as possible; or choose to take the interest class in the outdoor class, or take advantage of the sun after school to take the child out for a period of time and then go back to eat and learn... Try to choose a day on weekends as a time for the whole family to spend outdoors.
Do not let your child come into contact with electronic products such as mobile phones, tablets, etc. too early. Some experts remind preschoolers to minimize the use of electronic products, watch cartoons for no more than 15 minutes at a time, and accumulate no more than 1 hour per day!
For older children, in addition to looking at mobile phones, watching TV, puzzles, Lego, reading books, reading musical scores and other close-up eye activities, but also be vigilant, pay attention to abide by the "20-20-20" principle, that is, after 20 minutes with the eyes, pay attention to 20 feet (6 meters away) to look at no less than 20 seconds. There is also enough sleep to ensure that the eyes rest more.
Myopia is irreversible once it occurs, compared to correction, treatment, prevention is the most critical, so protecting vision is a long-term battle, which requires parents to pay attention to it from time to time.
