I will do this
First of all, this instrument is useless
Secondly, you should go to the hospital for dilated myopia first, if it is indeed 100 degrees myopia. And there are no other problems. You can temporarily stop wearing glasses for regular testing (2-3 times a month). If the prescription increases quickly, wear glasses immediately
Finally, before I talk about the principle, let me tell you what it is. The three-linked movement of the eyes together means that when the human eyes move from far to near, the eyeballs will turn downward and inward (linked movement). The amount of accommodation your eyes need to use during this process also increases. Due to long-term near vision, accommodation spasm will cause temporary blurring of distance vision, which is called pseudomyopia
Principle: These instruments use the internal light source to move far and near, so that the eye adjustment muscles can be exercised. , pseudomyopia can be restored. But it is useless for true myopia (of course it can be used to relax the eyes, so the naked eye vision will be slightly better after use, which is the main way these devices are used to cheat money). In fact, by relaxing your eyes, you can simply look far away or close your eyes to rest. No equipment is needed at all.
Summary: If myopia could be cured, we would have won the Nobel Prize long ago
