Elementary school students with 100 degrees of myopia, if it is false myopia, can be restored by adjusting the use of the eyes, if it is true myopia, can be corrected by prescription lenses. Myopia refers to refractive error, mainly due to the growth of the eye axis, resulting in imaging falls in front of the retina. Nearsightedness of 100 degrees belongs to mild myopia, and it is necessary to distinguish between true myopia and pseudomyopia. Pseudomyopia can be restored to the normal state of vision by adjusting the use of the eyes, relaxing the eyes and relieving fatigue. True myopia can be corrected by prescription glasses. Pay attention to your eyes in daily life, avoid reading for a long time, looking at electronic products and other bad eye behavior, and pay attention to resting after using your eyes for a period of time. If you experience vision loss or blurred vision, you should consult a doctor as soon as possible.
