How does the child's eyesight drop from 5.0 to 4.6 in half a year

The child's vision dropped from 5.0 to 4.6 in half a year, which may be caused by refractive errors such as myopia, hyperopia, astigmatism, or other eye diseases. The specific cause needs to be determined by detailed eye examination.

If the child has refractive errors such as myopia, hyperopia, astigmatism, etc., glasses can be considered for correction. For teenagers, wearing orthokeratology lenses (OK lenses) can help control the progression of myopia.

If your child's vision loss is due to other eye conditions, such as cataracts or glaucoma, treatment is needed. For example, cataracts require surgery, and glaucoma requires medication or surgery. At

ordinary times, parents should pay attention to their children's eye hygiene, encourage their children to participate in outdoor activities, control the use of electronic products, to prevent the occurrence and progress of myopia. At the same time, you can also appropriately supplement some foods that are beneficial to the eyes, such as foods rich in vitamins A, C, E and zinc, such as carrots, squash, spinach, fruits, etc.
