If a child is found to have refractive error after a dilated eye exam, treatment will be required to take into account the degree and specific circumstances. Refractive errors are classified as myopia, hyperopia and astigmatism. The goal of correction is to bring light into normal focus on the retina at the base of the eye through scientific methods. Children’s vision is primarily corrected by wearing appropriate frame glasses. Usually, children with pseudomyopia can return to normal after the eye exam and pupil dilatation. These children usually do not need to wear glasses for treatment, ensure good eye habits and eye hygiene, and get enough rest, and may be relieved on their own. Children under 6 years of age with mild hyperopia may be relieved or cured due to normal physiological development of the eye. These two types of children can be temporarily observed and not treated for the time being. Children with true myopia and moderate to high hyperopia, on the other hand, are usually recommended to be treated promptly to prevent their prescription from continuing to rise. In addition, after wearing glasses, parents need to take their children for regular vision review to prevent the treatment effect from being affected by the inappropriate prescription of glasses.
