For community or pediatric health checkups that are available, children may be screened for refractive error and other eye diseases at a few months of age; for children four years old or older, vision screening will be added. Why do we emphasize the importance of vision screening for infants and children, because prevention is definitely the most important. Community screening is usually a machine screening, if the child’s refractive power does not match his age, astigmatism is too large, hyperopia is too high, tend to myopia or directly found that his vision does not match his age, this part of the child should come to the optometrist for further precision examination; at this time, we will also check the child’s refractive power of the farsighted reserve, his eye length, corneal curvature, and so on. At this time, we will also check the child’s refractive reserve, the length of the eye, the corneal curvature, and evaluate whether the child’s refractive status requires treatment or close follow-up. If you find out that your child’s vision is lower than this value, you must go to the hospital to see if your child’s vision is too far ahead or too good. So don’t wait for your child to have a real problem before you come for a checkup, but a little earlier, in which case we will have a better control of your child’s vision and development.
