Recently, many parents have been asking a question: How do teenagers control myopia by controlling their lenses? It has also been found that after equipping their children with green control lenses, people still have some doubts about the principles and methods of children's eyeglasses lenses. Therefore, it is common to see the principles and precautions of controlling lenses for adolescent myopia.

At present, the control of myopia with kids' eyeglasses near me lenses is mainly based on two principles: one is to control the growth rate of the eye axis mentioned in the group before slowing down the degree increase. One way is to relax the tense state of children's eyes when they look up, reduce the fatigue caused by it, and alleviate myopia.

The lens designed based on the first principle is called a peripheral defocus childrens glasses lens, which is currently the most effective lens control method for the vast majority of teenagers.

Firstly, let's take a look at the next little knowledge. When light passes through the lens and refracts through the eyeball and happens to land on our retina, we see things most clearly. However, when light falls before and after the retina, it becomes blurry.

When light falls behind the retina, our brain sends a signal to our eyes to grow forward to see clearly, leading to an increase in the axial length of the eye and the occurrence or development of myopia.

When light falls in front of the retina, our brain, to avoid blurring, will slow down the forward growth signal of our eyes, reduce the speed of axial increase, and myopia can be controlled.
