What should twitching children do if they often blink?

There are many reasons why children blink. The most common causes are keratitis, conjunctivitis, dry eye, inverted eyelashes, ametropia, asthenopia, bad habits, eyelid spasm, hyperactivity, TIC disorder, and trace element deficiency.

So when you go to the ophthalmology department, you should first look at the slit lamp to see if the child has conjunctivitis, allergic conjunctivitis, itchy eyes and secretions from the gums, and then check whether the eyes are dry and whether the eyelashes grow back. Because eyelashes grow in the opposite direction, they can be tied to the black eyeball and cornea, which will cause damage to the cornea, leading to photophobia and crowded eyes.
