The development of eye vision is a gradual process of improvement, and under normal circumstances, the naked eye vision of a five-year-old child is between 0.6 and 0.8. So if a five-year-old child’s bare eye vision is 0.6, it is still within the normal range and there is no problem with this. In this case, it is generally recommended to take the child for regular vision checkups, usually every six months or so. If the vision is gradually improving as the child grows older, this is not a problem and is normal. If the vision does not improve with age or is declining, consider the possible existence of eye diseases, such as refractive error, amblyopia and other conditions, need to give symptomatic treatment for different conditions. In short, we must pay attention to the development of vision, and regular vision checkups are necessary.
