Why does my three-year-old baby keep blinking?

It is abnormal for a three-year-old baby to blink frequently. This not only affects the appearance and makes people think that the child has eye problems, but in the long run it will also make the child develop bad habits, which is very bad for both the present and the future. More importantly, if a child blinks for a long time, it will be very detrimental to the child’s eye development during the growth period, especially the development of vision. Therefore, as parents, we should pay attention to it.

Squinting is a normal physiological phenomenon of the human body. Its main function is to keep the cornea and conjunctiva moist. Generally, the interval between two blinks is more than a few seconds. If there is a paroxysmal rapid blink, it is an abnormal phenomenon. If children often blink and squint, it is worth noting. The main reasons are as follows:

1. External eye inflammation and allergic diseases: mainly trachoma, chronic conjunctivitis, spring catarrhal conjunctivitis, etc. Children feel discomfort in their eyes and blink excessively.

2. Eyelashes: Some children are fat and have thick subcutaneous fat on their eyelids, which can cause entropion and eyelashes, or idiopathic entropion and eyelashes. Because the eyelashes touch the cornea or conjunctiva, there is a foreign body in the eyes, causing stinging sensation, and the child often squeezes his eyes.

3. Caused by foreign bodies: Foreign bodies on the conjunctiva and cornea accidentally enter the eye, and after the child rubs the eye, the foreign body remains on the surface of the bulbar conjunctiva, cornea, or fornix, or the foreign body scratches the bulbar conjunctiva and cornea, causing the child to squeeze and blink.

4. Caused by watching TV and playing computer: TV and video games change images quickly, and the screen keeps flashing. Long-term viewing can cause hyperexcitement of the visual higher center balance inhibition. Because children's visual function is not yet fully developed, visual hyperexcitement can cause a feedback defense action - multiple blinks.

5. Bad habits: Some children have no abnormalities in their eyes after examination, but they have an involuntary habit of blinking, which becomes more serious over time. Some parents scold their children after discovering that their children have the habit of blinking and squinting, which will cause the children to be overly nervous and make the blinking and squinting phenomenon more serious.

6. When parents find that their children often blink and squint, they should first carefully ask their children if there is any discomfort in their eyes, whether they are itchy or have a foreign body sensation, etc., and then ask an ophthalmologist to check and treat the cause. If necessary, antibiotic eye drops can be given to the eyes, and the inverted eyelashes can be removed, and foreign bodies in the cornea and conjunctiva can be cleared. The children should also stop watching TV and playing on the computer. If blinking and squinting are bad habits, parents should not scold the children blindly, but educate them to try not to blink consciously.

Through the above introduction about the three-year-old baby who always blinks his eyes, we understand that it is a very bad habit for children to always blink their eyes. It not only affects the appearance but also hurts the eyes. Therefore, in daily life, as parents we have the responsibility to urge our children to break this bad habit and not indulge them by doting on them. This is not a sign of love for them, but rather harms them.
