A zero reserve of hyperopia does not necessarily mean nearsightedness. Hyperopia reserve generally means that the eyes are not fully developed in early childhood, at this time, the child’s eyes appear to have a certain degree of hyperopia, and the patient will have blurred vision and visual fatigue and other symptoms. Although the reserve of hyperopia is zero, with the gradual development of the eyes, the distance between the axes of the two eyes will gradually become normal, and the vision will be restored gradually. Even if there is no reserve for hyperopia, if there are no symptoms of blurring when looking at things, it indicates that there is no myopia. If there is a lack of clarity of distant objects, vision fatigue and other phenomena, then myopia can be considered, need to go to the hospital to dilate the pupil optometry, under the advice of the doctor to choose the appropriate correction method. Parents are advised to take their children for regular vision checkups and intervene promptly if problems are detected, so as not to affect the vision condition in adulthood.
