What is a farsighted reserve? Children with insufficient reserves of farsightedness may be short-sighted
We all know that children with insufficient hyperopia are prone to myopia. So what exactly is a farsighted reserve?
When we are born, our eyes are small and short in diameter before and after. At this time, the parallel light coming from 5 meters away enters the eye and focuses on the back of the retina. This is the case with farsightedness.
Our eye axis grows with growth and development, with each millimeter of degrees. The degree is increased by 300 degrees. At that time, the eye axis grows when the body grows rapidly. What is consumed is the farsighted reserve of our eyes.
When our farsighted reserve value decreases too quickly, it is easy to develop myopia. Because the early farsighted reserve is consumed too much, the reserve supply is also insufficient for later growth and development.
For the farsighted reserve, we must maintain it in time, like the usual reading habits, living habits should pay attention to protect our farsighted reserves. Outdoor activities for more than two hours can also reduce the risk of myopia, outdoor activities through the eyes to receive enough natural light, promote the secretion of dopamine in the eye, inhibit abnormal growth around the eyes.
