Why do children sometimes blink?

Blinking is a very normal thing for everyone, no matter if you are young or old, because blinking is a physiological need to keep the eyes moist. However, there is a limit to this. It is not normal to blink all the time. It may be that there is a problem in that part of the body. This is especially true for children, because they often cannot describe it very clearly. So let's talk about the reasons why children sometimes blink.

1. Inflammatory stimulation: This is the most common cause and may be bacteria. Caused by viruses, chlamydia and other infections, such as conjunctivitis, keratitis, etc. In addition to increased blinking, there are also symptoms such as redness and itching of the eyes, increased secretions, and tearing.

2. Congenital entropion and trichiasis: Some children are born with congenital entropion of eyelids (medically known as eyelids), which causes the eyelashes to fall on the surface of the eyeball, irritating the cornea (the surface of the black eyeball) and causing tears. In this case, entropion is the most common, and careful parents can find it.

3. ADHD in children: refers to the sudden, involuntary contraction and movement of a part of the child's body, such as blinking, frowning, twisting the mouth, shrugging, etc., as well as inattention and hyperactive behavior changes. Some children also make strange noises, or even swear and use bad words. This condition is medically called Attention Deficit Hyperactivity Disorder (ADHD) and Foul Words Syndrome.

4. Blinking due to eye fatigue: including visual fatigue such as refractive errors, especially uncorrected hyperopia, myopia, and astigmatism, which cause visual fatigue of the eyes. This is a protective reflex that adjusts the curvature of the eyeball through continuous blinking, allowing for clear vision.

5. Neurogenic blinking: It is caused by the frequent contraction of the nerve fibers that control the orbicularis oculi muscle after being stimulated.

6. Habitual blinking: Some children have a history of frequent blinking due to one of the above-mentioned causes. After treatment and the cause is eliminated, they still retain the habit of frequent blinking.

Above we have told you the reasons why children sometimes blink. Of course, it has also been mentioned that appropriate blinking is normal. What we want to talk about here is that children blink frequently. These things require parents to observe their children carefully and discover them early. Bad blinking habits should be corrected in time, and other diseases require early treatment.
