Every time I have a physical fitness test, my eyesight gets worse, so I don't increase the prescription for my glasses. If you don't know this, it's really frustrating and maddening. I'll be honest with you. Especially for parents of students with poor eyesight, this is something you must know. Hello, I'm optician Choi Byeong-moo. Are there anyone who has heard that their eyesight gets worse every time they get new glasses? Among those watching this video, there are probably people who are continuously stressed because their eyesight keeps deteriorating. If I weren't an optician, I would have been so frustrated and worried because I wouldn't have known about this aspect. But due to misunderstandings, many people end up completely ruining their eyes instead. Today, I will accurately explain this issue. I will talk about the reasons why nearsightedness continues to worsen and how to deal with it. This applies to almost 100% of students whose eyesight deteriorates every time they have an eye exam.

As this is important, parents, please pay attention. First, let me start with the conclusion. Elementary and middle school students with myopia will inevitably experience a continuous decline in vision. It is very normal for myopia to worsen continuously because myopia can develop not only due to issues with the cornea or crystalline lens but also simply because of the size of the eyeball. It may sound a bit complicated, but to put it simply, the more transparent the eyeball, the worse the myopia becomes. It has nothing to do with the size of the eyeball that is visible from the outside, so do not misunderstand it as the size of the eye. It refers to the size of the eyeball inside the face. Elementary and middle school students grow taller, and their heads also grow larger, which means their eyeballs also grow larger. However, as the size of the eyeball increases, the myopia worsens. Therefore, during the growth period, as height increases,

As the head grows, the eyes grow larger, so it's natural that nearsightedness increases and vision deteriorates. Sometimes people ask if continuous worsening eyesight might lead to blindness in the future, which can be a bit puzzling to hear, but I understand. However, the possibility of nearsightedness progressing to blindness is 0%, so you don't need to worry about that at all. Also, there are occasional misconceptions that wearing glasses and increasing the prescription to correct vision will further worsen eyesight, but that's incorrect. As I mentioned earlier, nearsightedness is mainly caused by the size of the eye, so it's unrelated to the prescription of glasses. After hearing what I've said, you might have some doubts. Well, then, the difference between worsening eyesight with or without wearing glasses is completely

It's okay, but do I have to keep getting glasses that match my deteriorating eyesight? If my eyes get bigger and my vision keeps getting worse, the prescription for glasses will increase anyway. Should glasses lenses be replaced every six months or a year to match that? For those who have doubts like this, I would like to explain why glasses should be replaced to match the prescription each time your eyesight changes. There are two very important reasons for this. First, especially for glasses during the growth period, it is necessary to accurately adjust the prescription to prevent amblyopia. Amblyopia occurs when the eyes are left in a state of poor vision for a long time. For example, if you spend a long time with a vision of 0.3, your eyes will just get used to that level of clarity. So, even if you later increase the prescription for glasses to see well, it is difficult to correct.

If the vision does not increase above 0.5, a very low level of limitation occurs. We call that condition myopia. In a way, it can be seen as a slightly damaged state. However, whether you increase or not the degree of glasses, the vision keeps decreasing, and myopia progresses. So, do you really need to replace them every time according to that? I think if you just leave it, even if you wear glasses, the corrected vision could be 0.3, and you may end up neglecting your eyes. By raising the degree to maintain around 0.9 to 1.0, you can keep your eyesight sharp and prevent myopia. Even if you undergo Lasik or Lasek surgery later on, the vision after the surgery mostly comes out to the level of corrected vision with glasses. So, even if you have myopia, the results of the surgery are not that good. Therefore, since the vision keeps decreasing anyway.

Even if it seems obvious to change your eyeglass lenses every 6 months to a year, you must change them correctly. The level of intelligence development and learning ability are closely related to how well you see. When nearsighted, squinting can make things appear much clearer than just looking at them big, so if your vision correction is not done properly, you might unknowingly start squinting. Even though it may not look good to others when they see it, squinting even a little can cause eye strain for yourself. If this continues to accumulate, how will it affect your concentration? Basically, humans receive a considerable amount of information through their eyes into the brain. If you just think about it a little, this is really basic, and depending on how well you see, it can make a big difference. I think everyone knows this. But anyway, your vision will eventually deteriorate.

So, even if you can only watch about 0.5, skipping the replacement of glasses lenses is really unreasonable. Today's content may have been a bit difficult, but it's really important. Have you understood the reasons for the continuous decline in vision and how to deal with it? Next time, I will upload a video with better content.
