What is hyperopic reserve?

Generally speaking, the eyeballs of newborns are small, the eyes are not yet fully developed, the length of the eyeballs (eye axis) is short, and they are in a state of hyperopia! Then, as they grow and develop, the front-to-back diameter of the eyeballs will gradually increase, the hyperopia reserve will gradually disappear, and the vision will slowly transition from hyperopia to emmetropia, and generally reach full emmetropia around the age of 12.

A child's vision will go through the stages of [hyperopia-normal-myopia], and what is consumed during the development process is the [hyperopia reserve]!

Hyperopia reserve is like a "piggy bank" for the eyes, protecting them from myopia. However, if we don't pay attention to protecting it, the "piggy bank" will become less and less.

The amount of hyperopia reserve is an important indicator to determine whether a child will develop myopia. With the advancement of science and technology, people's lifestyles have changed dramatically. Children and adolescents use their eyes for a long time at close range, with heavy loads, are overly dependent on various electronic products, and have fewer and fewer outdoor activities. In the long run, this will lead to the premature consumption of children's hyperopia reserve, and ultimately lead to the high incidence of myopia among children at a young age.

Misconceptions about hyperopia reserve

① The more hyperopia reserve, the better

If the hyperopia reserve is too large and the eyes over-adjust themselves, it will be difficult to see clearly near or far, or even amblyopia.

② Insufficient hyperopia reserve ≠ myopia

The rapid consumption of hyperopia reserves only increases the risk of myopia, not myopia! At this time, it is necessary to pay attention to the child's vision problems and slow down the consumption of hyperopia reserves. There is no need to worry!

If a child’s hyperopia reserve decreases, can it be restored?

The reduction of hyperopic reserve is marked by the growth of axial length.

Theoretically, the eyeball has become longer and cannot be retracted. It may not be easy to restore the reduced hyperopia reserve.

However, it is not too late to make up for the loss. Parents should adjust their children's lifestyle and state in time to adapt to the characteristics of their visual function development and not let their visual burden overwhelm their underdeveloped visual system. Parents should pay attention to:

① Increase children’s outdoor exercise time

Outdoor exercise is the best way to prevent excessive consumption of hyperopia reserves. More than two hours of outdoor activities a day can effectively delay the consumption of hyperopia reserves.

② Cultivate good eye habits in children

Parents should always check the indoor lighting and provide their children with a well-lit eye environment, which can also delay their children's visual fatigue when doing homework.

Supervise your children to use their eyes properly. The time for reading or doing homework should not exceed 30 minutes at a time. Take a ten-minute break every 30 minutes to look into the distance or close their eyes to rest.

Never let your children read while lying down or lying on their stomachs. They should sit upright and follow the principle of "one inch, one foot, one fist".

③Guide children to develop good eating habits

Ensure balanced nutrition and do not be picky about food. Eat more fruits and vegetables and reduce sugar intake.

④ Establish a refractive development file for your child

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.
