Some parents of children in the clinic often ask how to prevent poor vision in children, the following points please pay attention to! 1. Squint a lot when looking at objects People with myopia often squint when looking at things. This is because the eyelids can block part of the pupil when squinting, which reduces the scattering of light and thus can temporarily improve and enhance vision. Therefore, when your child is squinting a lot, you should consider that he or she may be suffering from early myopia. 2. Frequent blinking Frequent blinking can, to some extent, relieve myopia and enhance visual acuity. Therefore, when your child shows symptoms of frequent blinking, you should consider whether he or she has early myopia. 3. Frequent eye rubbing Some children who have difficulty seeing objects because of myopia often rub their eyes with their hands in order to see objects better. Therefore, when you find that your child often rubs his or her eyes, you should take him or her to the hospital to have his or her vision checked promptly. Some children with early myopia often look at objects with their heads tilted. This is because looking at objects with their head tilted reduces the effect of scattered light on their vision. Therefore, when you find that your child often looks at objects with his head tilted, you must take him to the hospital for a vision check and to correct his wrong posture in looking at objects so that he does not develop the habit of tilting his head. 5, often frown Some children with myopia have the habit of frowning. This is a way for them to try to improve their vision. However, frequent frowning can cause the extraocular muscles to press on the eye, which in turn can speed up the development of myopia. Therefore, when you notice your child frowning a lot, take him or her to the hospital for a vision check. And to help it to change the problem of frequent frowning. 6, often pull the corner of the eye A few children with myopia often pull the corner of their eyes with their hands to the outside, because doing so can have the same effect as tilting the head and squinting. Therefore, when you find that your child has the habit of pulling the corners of his or her eyes, take him or her to the hospital to have his or her vision checked in a timely manner. Some children with myopia often have the habit of strabismus (i.e., when one eye looks forward, the other eye looks outward involuntarily). Therefore, when you find your child has the habit of squinting, you should consider whether he or she has myopia. When your child always looks close to objects and complains that the light in the room is too dark when reading and writing, consider that your child may have myopia. When your child often does not greet people he or she knows, trips or bruises when moving in the dark, or cannot see the handwriting on the blackboard, consider whether your child has myopia.
