What is the symptom of pseudomyopia?

summary

With the development of society, the number of myopia patients in China is on the rise, especially the number of teenagers suffering from myopia is the most. However, there are two kinds of myopia, one is true myopia, the other is false myopia. So what is pseudomyopia? Here is an introduction. Pseudomyopia is caused by excessive use of eyes, resulting in continuous contraction of ciliary muscle spasm, increased lens thickness, blurred vision. Pseudomyopia is actually functional myopia. Pseudomyopia in the treatment of time is also very good treatment.

What is the symptom of pseudomyopia?

The formation of myopia is caused by various factors, which can make the anterior and posterior diameter of the eyeball longer. After parallel light enters the eye, it forms a focus in front of the retina, causing blurred vision. On the surface, pseudomyopia is also blurred in the distance and clear in the near, but there is no corresponding change in diopter during mydriasis optometry.

So why can't pseudomyopia see things far away? This is because often incorrect use of the eye, making the ciliary muscle continuous contraction, spasm, can not get the rest, the lens is also in a state of thickening. In this way, the parallel light enters the eye, and after the lens is thickened and bent, the focus falls in front of the retina, so it is not clear to see things in the distance.

In this period of time of pseudomyopia, because the eyeball has not become long, if we can have treatment and proper rest during this period of time, we should also pay attention to eye hygiene, reasonable use of eyes, there is still hope to return to normal vision, so it is called pseudomyopia. If not corrected and treated in time, it will become true myopia.

matters needing attention

Because teenagers have strong adjustment ability, they are prone to pseudomyopia, but a small number of adults engaged in near work can also have pseudomyopia. With the increase of age, the adjustment reaction time is gradually extended, and the elderly with emmetropia may have temporary myopia when they suddenly look far after looking near, which is also called physiological pseudomyopia.
