Abstract: for the eyes that have been myopia, if the degree of glasses does not match, or habitually squint, you have unconsciously made the degree of myopia become higher and higher. This is why many children have been equipped with glasses, but the degree is still deepening.
when we can’t see clearly, we often squint because we can see more clearly. Why can you see more clearly by narrowing your eyes? For a long time, it has been believed that squinting will change the shape of the eye, but the real answer is not so.
squint at things. From the optical principle, it is to narrow the aperture, just like looking at the scene through a small hole. It seems that they will see more clearly. The problem is that if you squint at things for a long time, it will be a pressure on the eyeball. Over time, the eye axis will also elongate, which will virtually aggravate the degree of myopia.
myopia without glasses,
squinting what are the hazards?
1. Eyes are more likely to be tired.
always like to squint at things. Although they can see more clearly, they are actually more laborious. If they look like this for a long time, their eyes are more likely to be tired, especially the students in school. Their learning pressure is relatively high. If they always squint at things, their eyesight will decline faster and faster.
2. Deepen myopia
originally myopia eyes. If the degree of glasses is inconsistent, or habitually squint, then you have unconsciously made the degree of myopia become higher and higher. This is why many children have been equipped with glasses, but the degree is still deepening.
3. It may be that the eyes have astigmatism.
squinting can improve vision to a certain extent through the pinhole effect and fissure effect in physics. Therefore, astigmatism patients often squint when looking far away, and can correct this bad habit after wearing glasses. It should be noted that squinting is not an inherent manifestation of astigmatism, and it can also occur in patients with myopia.
of course, if the baby squints at things, the parents should also leave snacks, which may be a phenomenon of amblyopia. Parents and friends always pay attention!
children’s low vision is not necessarily irreversible. The key lies in how to prevent and treat it. Careful parents should always pay attention to their children’s eye use in order to avoid eye health problems.
