Refractive errors in children may heal on their own. Children’s eyes are not fully developed when they are small and such a condition occurs, and some children will have their symptoms gradually alleviated as they grow older. Refractive error is actually a collective term for myopia, hyperopia and astigmatism. Nowadays, cell phones and computers are very common, and very young children will play with cell phones and computers, so children will have astigmatism, myopia or hyperopia at a very young age, and there is no need to worry too much about this situation, as some children’s symptoms will gradually ease as they grow older. But the prerequisite is to let the child change the bad habits of using the eyes, reduce the time to look at the phone, look at the computer, if necessary, you can also give the child glasses to correct. When the child is younger, the effect of correction is also more ideal. You can let children eat more carrots and blueberries, and also pay attention to let children maintain a correct sitting posture, do not use the eyes for a long time, you can do eye exercises or use eye drops to relieve eye fatigue.
