Because the eyes of a child continue to develop as they grow, children may exhibit particular signs of vision problems that can be corrected if found early enough. Such signs include red eyes, eyes that look different from the usual, more tearing, misaligned eyes, tilting of the head, crossed eyes after six months, development delay, blurry vision at all distances, and different-sized pupils with an unusual color. You should also call your eye doctor if the child complains of eye discomfort, rubs the eyes a lot, seems extremely sensitive to light, and has problems focusing on objects. School-going children may have trouble seeing distant objects, reading, reading the blackboard, and watching TV from a distance. They may also squint or complain of headaches.
