It is normal for a 10 year old to have vision of 1.2 in both eyes, while it is abnormal if the vision in one eye is 1.2 and the other is below 1.0.
Under normal circumstances, the vision of a 10-year-old child should be maintained between 1.0 and 1.5, which means that if the child’s vision is 1.2 in both eyes, it is within the normal range and there is no need to worry too much.
However, if only one eye has a visual acuity of 1.2 and the other eye has a visual acuity of less than 1.0, this is not normal, and myopia is likely to exist, and a dilated optometry should be performed promptly. If myopia is confirmed, you need to take reasonable eye use and wear glasses according to the situation, so as not to cause myopia to continue to aggravate.
Vision is still very important to the future of children, need to pay enough attention to regular checkups in the hospital, in order to timely detection of problems and timely intervention.
