The farsightedness reserve of a 6-year-old child is between 100~150 degrees, and a farsightedness reserve of 75 indicates that the farsightedness reserve is insufficient, which may be caused by the child’s usual bad eye habits, resulting in the early development of the refractive state of the eyes. Insufficient farsightedness reserve is mainly caused by bad eye habits, such as watching electronic products, watching cell phones or computer screens for a long time, so that the eyes are in a state of long-term fatigue, so that the eyesight is damaged, which can easily lead to myopia, and can be corrected by wearing glasses. Maintaining good eye habits in life, avoiding reading and writing in poorly lit environments, maintaining good sitting posture; and looking at more green plants can protect the eyes very well. 6-year-old children with hyperopic reserve deficiency, timely to the hospital, take to take reasonable treatment methods, so as not to lead to myopia and so on.
