How long will it take for a child to have insufficient hyperopia?

Before the age of 3 is the formation of visual development, if at this stage, the child's visual function is not well developed, the child is prone to myopia. It is particularly prone to monocular myopia, refractive error, rapid growth of myopia, eye fatigue and other vision problems. 3-6 years old is a critical period for children to cooperate with the examination, which needs to be checked regularly, and problems are found and corrected in time. Prevention and control of adolescents is a must pay attention to the role of farsighted reserves.

What is a farsighted reserve? What is the relationship between hyperopia reserve and myopia? What exactly do ophthalmologists mean by farsighted reserves? Before understanding the reserve of farsightedness, let's first cover these three concepts: farsightedness, orthopedic, and nearsightedness.

● Hyperopia, where objects seen by the eye fall behind the retina after passing through the refractive system of the eye;

● Facing, the object seen by the eye falls on the retina after passing through the refractive system of the eye, and the object can be seen very clearly;

● Myopia, where objects seen by the eye fall in front of the retina after passing through the eye's refractive system.

That is to say, the length of the eye axis determines the imaging position of the object in the retina, and the child's vision is directly related to the development of the eye axis. Newborns and preschool children because of the small eyeballs, short eye axis, before the development of adult level, the objects seen by the eyes through the refractive system of the eyes fall behind the retina, forming hyperopia, which is a normal physiological phenomenon, this physiological hyperopia is what ophthalmologists call "hyperopia reserve".

How much should there be in the farsighted reserve?

Generally speaking, children have a degree of farsightedness between 3 and before school, and the degree of hyperopia is about 100 to 300 degrees, and as they grow older, the degree becomes lower and lower. The reserve of farsightedness in each age group is not refined to specific standards, because there are certain differences in the development of each child.

As the child grows and develops, physiological farsightedness will gradually disappear, this process is irreversible, about 12 years old from farsighted development to positive vision, this process is also known as the process of orthodonization.

What is the relationship between hyperopia reserve and myopia?

Farsighted reserve is equivalent to a "buffer zone", if children have bad eye habits such as looking at electronic products for a long time, incorrect reading and writing posture, it is possible to consume farsighted reserves too quickly, and the development of face-up is accelerated. If the habit of excessive use of eyes is still present in the case of rapid consumption of farsighted reserves, it is possible that the car may not be able to brake and develop to myopia. Therefore, there will be a saying that "the reserve of farsightedness is almost gone, and we must pay attention to the formation of myopia". However, low hyperopia does not necessarily mean that it is fast myopia. The reserve of farsightedness is generally decreasing, but usually not plummeting, and each child declines at a different rate.

What should I do if I have insufficient farsighted reserves?

● More outdoor "eye bath sunshine" outdoor activities during the day can avoid premature consumption of hyperopia reserves, and effectively reduce the incidence of myopia. However, be careful not to let the harsh sunlight directly hit the eyes, so as not to cause damage to vision.

● Correct bad eye habits, adhere to the scientific use of eyes Parents and teachers should pay attention to children's reading and writing posture, develop good habits in peacetime, and strictly control the use of electronic screens. Parents and teachers should pay attention to children's reading and writing postures, develop good habits in normal times, and strictly control the length of use of electronic screens.

In fact, it is not difficult to do a good job in the prevention and control of myopia in children, and doing the following points will greatly avoid the premature occurrence of myopia in children:

1, adhere to good eye habits and healthy lifestyle,

2. Use electronic products as little as possible in front of your child.

3. Urge children to maintain correct posture when reading and writing,

4, do a good job in daily maintenance, increase nutrient supply,

5. Conduct regular vision examinations to prevent myopia from worsening.
