Is 0.6 normal?

The first thing to distinguish is the age of the patient, because the normal range of vision changes during the development of children. If vision of 0.6 is a relatively normal vision for a three-year-old child, and if vision of 0.6 is not considered normal vision for an older child or adult, it is necessary to check whether there is a cause of vision deterioration, if there is a disease affecting vision, treat the relevant disease, and if there is a refractive error, decide whether to wear glasses to correct the refractive error according to the patient's needs. After removing the cause of vision loss, the eye can return to normal vision of 1.0.
