We often see children who blink involuntarily and frequently, and some doctors prescribe eye drops that have no effect. First of all, you should ask your child if he or she has been watching a lot of TV or playing with a cell phone lately. If the blinking is caused by eye use, you should consider video terminal syndrome and use medications such as artificial tears, and if you find that there is epithelial damage to the cornea, you can use medications that promote epithelial repair. This type of child is often associated with partial eating habits, so it is also necessary to correct the bad habits of partial eating and to supplement vitamin A and other trace elements.
