Most people do not understand "pseudomyopia". Pseudomyopia is generally easy to appear in childhood, and parents simply think that pseudomyopia does not need to be dealt with, and the child's vision will automatically recover after a period of rest. Most parents still take a fluke and think that their children are still young, which must be pseudo-myopia, and there is no need to specifically check them, but in fact, this practice actually delays the children.
1. What is pseudomyopia?
"Pseudo-myopia" does not belong to the true sense of myopia. It is actually a type of ciliary muscle that is continuously contracted and spasm due to excessive adjustment, and the thickness of the lens increases, so that the image of the object is in front of the retina, because its symptoms are the same as myopia. But it is essentially different from myopia, so it is called "pseudo-myopia". Pseudo-myopia is a functional abnormality and is reversible!
2. Once a child has "pseudo-myopia", it may be accompanied by the following symptoms:
(1)Â Blurred vision and unstable vision;
(2) Eye swelling and headache after close work;
(3) Sensitive to light and photophobia;
(4) It is not clear to see far, it will be relieved after a while, and it is difficult to focus when changing from near vision to far vision.
3. The concept of myopia:
The myopia we often say is due to the growth of the axis of the eye or (and) the steepening of the corneal curvature, which changes the overall refractive state of the eye, so that the object cannot be clearly imaged on the retina, showing that it is not clear to see far. It is irreversible!
4. The difference between "pseudo-myopia" and myopia:
The reasons for the two are different: "Pseudo-myopia" is an abnormal visual function. Due to excessive adjustment, the lens becomes convex and the object is imaged in front of the retina. And myopia is a change in the overall refractive state of the eye, causing the object to be imaged in front of the retina. The symptoms of the two are similar but slightly different: myopia is manifested as unclear vision, while "pseudo-myopia" is not only manifested as unclear vision but also accompanied by symptoms of photophobia, visual fatigue and over-regulation. The biggest difference between "pseudo-myopia" and myopia is that "pseudo-myopia" can be relieved or eliminated by relaxing the adjustment, but the degree of myopia will not decrease or eliminate.
5. How to find out if the child is "pseudo-myopia"?
We can distinguish "pseudo-myopia" and myopia by dilating pupils. Mydriasis is the use of drugs to paralyze the ciliary muscles, relax the multi-purpose adjustment, and obtain true refractive power to eliminate "false myopia".
6. When the child has pseudomyopia.
Children and adolescents who overuse their eyes for a long time cause excessive eye fatigue, long-term ciliary muscle spasm, and symptoms of myopia are called pseudomyopia. Pseudo-myopia can be gradually cured by correcting bad eye habits. In this case, massage can relax the ciliary muscles to relieve symptoms and even restore vision.
How to prevent "Pseudomyopia"
1. Pay attention to use your eyes, combine work and rest
Normally studying, working, watching TV or playing with electronic products hurt your eyes. You must always remember to give your eyes a proper rest or do eye exercises. It is best to look at the windows when you are resting, and look at distant objects and green ones. Objects, adjust the eye muscles to relax, so that the eyes can get a proper rest.
2. Pay attention to the surrounding light environment
Too dark or too strong light will affect vision, too strong light stimulates the eyes to be highly strained, and the damage of strong light to the eyes is very direct. If the light is too weak, it will affect the eye's ability to adjust the light over time. Therefore, when using the eyes, try to ensure that the light is appropriate.
3. Participate in outdoor activities
When the outdoor light is strong, the pupils shrink naturally. After the pupils shrink, the depth of field will become deeper, and the effect of blur will be reduced. Defocus blur is also reduced. Retina imaging is clearer, reducing the myopia induction of blur to the retina, and reducing the use of eyes to the greatest extent Fatigue, at the same time, outdoor activities help children's physical exercise and physical enhancement, and it is also very good for the eyes.
4. Maintain adequate sleep
Sleep is also a critical moment for the recovery of eye metabolism and physiological function. Often staying up late, the eyes are red and swollen, or dark circles under the eyes, this will undoubtedly be very harmful to the eyes, let alone the restoration and adjustment of vision. Therefore, maintaining a good and adequate sleep is also a prerequisite and basic guarantee for the restoration of vision.
