The main manifestations of early myopia are squinting, squinting, blinking, and inability to see for long. The main cause of early myopia is visual fatigue. Visual fatigue is caused by excessive close eye use and over-adjustment of the ciliary muscle, which causes fatigue in the eye, resulting in blurred vision. In addition, eye pain or dry eyes are all signs of early myopia. Therefore, for children with these symptoms, it is recommended that they should go to the eye care department of a regular hospital for a vision checkup, a naked eye vision check, and preferably a dilated eye exam to determine whether they have true myopia or pseudomyopia, so that they can take appropriate treatment and preventive measures.
