Blink

Introduction Under normal circumstances, the interval between two blinks is more than a few seconds, and if there is a paroxysmal fast blink, it is an abnormal phenomenon. Frequent blinking of the child is common in clinical ophthalmology, and there are several situations in which the child blinks frequently. One is when the child's eye conjunctiva has inflammation, the child is uncomfortable, the eye has a foreign body sensation, and the secretion of foreign body through the blink of an eye and tears can temporarily relieve the foreign body sensation of the eye. This is the main reason. Another is that when the child has fatigue, the refractive error may also occur. There is also a child's nervous blinking.

Cause

1. External eye inflammation and allergic diseases: mainly trachoma, chronic conjunctivitis, spring catarrhal conjunctivitis, etc., children with conscious eye discomfort and excessive blinking.

2. Trichiasis: Some children grow fatter, and the eyelids are thick under the skin, causing palpebral palpebral palpebral or idiopathic palpebral palpebral palpebral. Because the eyelashes touch the cornea or the bulbar conjunctiva, it causes foreign bodies and tingling in the eyes, which makes the children often squeeze their eyes.

3. Foreign body causes: foreign matter in the conjunctiva and cornea surface inadvertently enters the eye. After the child rubs the eye, it causes the conjunctiva or cornea of the ball, the foreign body on the crotch surface remains, or the foreign body will bruise the conjunctiva and cornea, causing the child to squeeze. Blinking phenomenon.

4. Watching TV and playing with the computer cause: TV, video images change quickly, the picture keeps flashing, and long-time viewing can cause super-excitement of visual high-level balance suppression. Because children's visual function development is still not perfect, visual hyper-excitation can cause a kind of feedback defense action - multiple moments.

5. Bad habits: Some children have no abnormalities in the eyes after examination, but an involuntary habitual blinking, which is getting worse for a long time. Some parents find that their children have blinks and squeezing their habits and then scolding their children. This will cause the child to be overly nervous, causing blinking and eye-catching.
