The most common reason children have difficulty seeing clearly is refractive error. Refractive errors are divided into myopia, hyperopia, and astigmatism. Parents often believe that only myopia and astigmatism affect children's vision; however, moderate to high hyperopia is a major cause of amblyopia in children.
In hyperopia, the optical focal point is behind the retina, resulting in a blurred image on the retina. In this case, children see both near and distant objects unclearly. If a child experiences blurred vision, a comprehensive eye examination should be performed first to determine if further treatment is needed.
Does wearing glasses too early cause nearsightedness to worsen?
Once a child is diagnosed with nearsightedness through a cycloplegic refraction test, they should wear glasses promptly. Without glasses, a child must adjust their eyelids to focus on the retina to see a distant object clearly. Prolonged self-adjustment can lead to ciliary muscle spasm, increasing nearsightedness.
In conclusion, it is only by not wearing glasses that nearsightedness will the degree of nearsightedness worsen. Wearing glasses will not cause the eyeballs to bulge or become "fish-eye"; this is due to the elongation of the eye axis caused by nearsightedness.
Is myopia curable once diagnosed?
Myopia is irreversible once it occurs.
Myopia causes the axial length of our eyes to increase. Once the axial length has increased, it cannot be restored to a healthy state through treatment or massage. What we can do with myopia is try to prevent pathological changes in the eyes, such as macular degeneration, macular hemorrhage, or even retinal detachment. These conditions can seriously affect a child's eye health.
Does that mean children of parents who are not nearsighted will not develop nearsightedness?
The fact that parents are not nearsighted does not guarantee that their children will also have vision problems.
There are two main causes of nearsightedness:
First, genetic factors.
Children whose parents have high myopia (over 600 degrees) have a significantly higher risk of developing nearsightedness than children whose parents are not nearsighted.
Second, environmental factors.
Prolonged close-range use of the eyes and poor eye habits can both lead to nearsightedness in children. Nearsightedness is a lifelong process and does not stop developing with age.
How to prevent myopia?
The most effective and economical way to prevent myopia is to engage in plenty of outdoor activities. Studies have shown that two hours of outdoor activity daily can effectively prevent myopia.
Secondly, parents should control the amount of time children spend using electronic devices. It is not recommended for children under two years old to use electronic devices. If school-aged children do need to use electronic devices, parents should break up the time allotted for each use, ensuring that each session does not exceed half an hour.
