If we are nearsighted when our eyes are in a relaxed state and parallel light enters the eye, it will focus in front of the retina, so clear images cannot be formed on the retina. At this point, it is necessary to wear a concave lens for correction, so that the light can be focused on the retina.

For children, as their eyeballs are still developing, once myopia occurs, the degree will continue to progress. Many parents may feel like they can't take off their glasses anymore, so they think we should not wear glasses for now.

In fact, this is just a pot on the back of glasses, because the progression of myopia is related to the eyes themselves and their usage habits. Wearing childrens glasses correctly not only helps to see things clearly, but also slows down the development of myopia. Long term blurring of the eyes can accelerate the development of the degree.

If one eye sees things clearly and the other eye is blurry, it may affect the brain's binocular fusion function for a long time. Not only may it make the visually impaired eye see things worse, leading to amblyopia, but it may also affect the establishment of binocular stereo vision.

If the images obtained on the retina of both eyes are blurry, it not only affects children's learning and life, but also affects the visual development of the brain and may lead to amblyopia.

Moreover, wearing childrens glasses or not may also affect the eye position, that is, the position of the eyes. This is because, with normal eyes without degree, when looking far, they can see clearly in a relaxed state. When looking close, they need to use adjustment to see clearly, and at the same time, their eyes will converge inward.
