There is a tear film on the surface of our eyeballs that is used to lubricate our requirements, especially the cornea, without which our ocular surface will feel dry.
However, because the tear film is a liquid, it is easy to evaporate, so we need to secrete the tear film by blinking so that we can continue to lubricate the eyeball, so we need to blink frequently.
Some people tend to have dry eyes because the tear film breaks up faster, so they blink faster.
-
There are many causes of frequent blinking. For example, the chronic inflammation of the eyelid conjunctiva, the decrease in tear secretion, the stones of the eyelids, the chronic inflammation of the conjunctiva, and the trichiasis can all cause frequent blinking. After the examination, the symptoms are treated according to the situation**.

It's the eyes protecting themselves.

Question 1: Why do my eyes always blink? Blinking is to protect the moisturized eyes.
It turns out that the eye has tear glands, which store tears, and every time you blink, the tear gland opening is pressed, and tears flow out, preventing the eyes from drying out. It can be said that every time you blink, you are "crying". Do you understand now?
Question 2: Why do you blink hard all the time? Recommendations:
Squeezing eyes, also known as blinking, is a normal physiological phenomenon of the human body, and its main role is to ensure the wetness of the cornea and conjunctiva. Under normal circumstances, the interval between two flashes is more than a few seconds, and if there is a paroxysmal rapid instantaneous sail and sudden fainting, it is an abnormal phenomenon. Children blink a lot, and if they squeeze their eyes, it is worth noting.
The main reasons for this are as follows:1Inflammation of the external eye and allergic diseases:
Mainly trachoma, chronic conjunctivitis, spring catarrhal conjunctivitis, etc., the child feels eye discomfort and excessive blinking. 2.Trichiasis:
Some children grow fatter and have thick subcutaneous fat on the eyelids, causing entropion trichiasis, or idiopathic entropion trichiasis. Because the eyelashes touch the cornea or bulbar conjunctiva, it causes a foreign body and stinging sensation in the eye, and children often squeeze their eyes. 3.
Caused by foreign bodies: foreign bodies on the surface of the conjunctiva and cornea accidentally enter the eye, and after the child rubs the eyes, the foreign body on the surface of the bulbar conjunctiva or cornea and fornix remains, or the foreign body abrases the conjunctiva and cornea, causing the child to squeeze the eyes and blink. 4.
Watching TV and playing with the computer causes: TV, video game images change quickly, the picture keeps flickering, and a long time ** can cause super excitement of visual advanced center balance inhibition. Because children's visual function is not yet fully developed, visual hyperexcitement can cause a kind of feedback defensive action multi-moment.
5.Bad habits: Some children do not have any abnormalities in their eyes after examination, but an involuntary habitual blinking, which becomes more serious over time.
Some parents scold their children after discovering that they have the habit of blinking and squeezing their eyes, which will cause their children to be overly nervous, making the phenomenon of blinking and squeezing eyes more serious. When parents find that their children often blink and squeeze their eyes, they should first carefully ask their children what is uncomfortable with their eyes, whether they are itchy and have a foreign body sensation, etc., and then ask an ophthalmologist to check and carry out **, if necessary, the eye can be dripped with antibiotic eye solution, trichiasis, and cornea and conjunctival foreign bodies can be removed. Also stop watching TV and don't play on the computer.
If it is a bad habit of blinking and squeezing eyes, parents should not blindly reprimand their children, but should educate children not to blink and squeeze their eyes consciously as much as possible, and gradually overcome the bad habit of blinking and squeezing their eyes.
Question 3: Why do my eyes keep blinking? Eyes will also be tired, blinking more can prevent overwork of the eyes, moisten the eyeballs, prevent interference, if you work on the computer for a long time, you had better look at the distance for a few minutes every one or two hours, to avoid long-term eye fatigue, resulting in myopia.

Why do people blink, in fact, is a natural physiological phenomenon, just imagine if you don't blink, staring at the eyes all the time, after a while the eyes will be tired, uncomfortable, especially important will appear obvious dry eyes, blurred vision, etc., these conditions will inevitably occur, so normal people will blink. By blinking, a tear film is distributed on the surface of the eye, and the film-like structure produced by tears is called tear film. Tear film has the effect of protecting and lubricating the eyes, and also improves the clarity of the eyes.
Dry eyes can occur if the tear film is incomplete or the tear film is very short, and the tear film breaks for a very short time. After dry eyes, there will be symptoms such as eye astringency, foreign body sensation, fatigue, etc., normal life blinks rationally about 20 times a minute, if there is a situation that does not like to blink and aggravate dry eyes, it is necessary to pay attention to conscious blinking can alleviate the dry condition.

The eyes are blinking and blinking, cleaning the surface of the eyeballs, and really helping you look forward to it

Each of us blinks non-stop every day, normal people blink 10 to 20 times per minute, each blink time is about seconds, not counting sleep time, a person blinks about 10,000 times a day, the busiest in the human body is the levator muscle. The interval between each blink is only 4 to 5 seconds.
Don't underestimate the simple and short act of blinking, it's not small at all. What exactly does blinking do? To find out what the blink does, I looked up "100,000 Whys".
When blinking, tears are evenly applied to the cornea and conjunctiva, which can be that they are moist and not dry. Blinking also encourages tears to drain, which is why you automatically close your eyes every time they feel dry. In addition, blinking an eye is the same as wiping a "glass window" to keep the eyes clean at all times.
As we all know, when flying insects or other objects suddenly fly towards the eyes, our eyes will react quickly to prevent the flying insects from flying into the eyes, so as to avoid or reduce the damage to the eyeballs.
Closing your eyelids when blinking prevents light from constantly entering your eyes and gives the retina under your eyes a short rest. Don't look at blinking as just an "instant", add it up, it's 1 hour a day. In other words, we have to be "blind" for one hour a day, but we don't feel the "darkness" ourselves.
Some scientists believe that when the retina rests for a short time, it is the brain nerves that transmit the last information from the retinal nerve cell receptors, and there is no time to analyze the next visual impulse that is transmitted to the nerve center, so we can't feel the darkness.
Blinking weakens the intense light that hits the bottom of the eye, much like a curtain blocking sunlight. It can be imagined that if the eyes are always open and the light is constantly shining on the retina, then it will not take long for our eyes to weaken their vision, and it is likely that they will be tired to the point of blindness.
Blinking relaxes the levator palpebrae muscle, and if you leave it motionless, you may feel sore, sore and swollen eyes. Blinking can help the eyes get rid of foreign bodies, such as dust particles.
It turns out that blinking has such a big effect. Students must not swell their eyes in the future, and they must blink often. However, you should not blink too much, that may be a sign of illness. The eyes are the windows of the human soul, and we must protect them well.
Excessive stress is also the cause. But habit should be more important. Try to get used to controlling it yourself.

What's the deal with blinking and what should I do?
1. Drugs**: For keratitis and conjunctivitis, the doctor instructs to rinse the secretions with normal saline or 3% boric acid solution, local antibiotic eye drops such as chloramphenicol or rifampicin eye water, herpes net eye drops or cyclocytidine eye drops for viral infection, and oral antibiotics for severe cases. Symptomatic treatment of trichiasis, stye, or chalazion.
2. Psychology: Frequent blinking has no adverse effect on the eyes themselves, so parents do not need to be too nervous and worried, and can not put pressure on their children in the form of abuse. Once the blink is attacked, parents can ignore it and let it be natural, or they can arrange appropriate entertainment activities to divert their children's attention.
When the cause is unknown, parents should not blindly use drugs. Usually give the child a reasonable diet, limit the time the child watches TV, maintain sufficient sleep time, and ensure a regular life.
3. Health examination: in addition to general items, it can also include stool worm detection (positive ones, deworming can be done**); When conditions permit, dilated eye refraction can be carried out in order to understand the refractive status of the child in time, low vision and refractive error should be corrected in time, individual blinks are serious or long-lasting, or accompanied by systemic abnormalities, should go to pediatrics, neurology for treatment, or consult a psychologist.
4. The symptoms of frequent blinking can be regarded as a kind of feedback defensive action caused by visual hyperexcitement. Secondly, facing the fluorescent screen at close range for a long time, the flickering screen screen screen screen and the dark environment of the room form a strong contrast, which increases the burden of eye adjustment. Studies have confirmed that watching TV for 30 to 50 minutes has no obvious effect on children's vision, but if it lasts for more than 2 hours, it can cause more than 60% of children to have varying degrees of vision loss, and visual fatigue increases significantly, but repeated this can cause damage to vision.
At this time, the child may be able to adapt to his or her eyes**.
Precautions. If the child is found to have frequent blinking, the child should stop watching TV for 2 to 3 months if the diagnosis is clear. After the symptoms disappear, it is advisable to watch TV for no more than half an hour every day for 2 3 years old, no more than 1 hour for 4 6 years old, and no more than 1 and a half hours for 7 10 years old. The distance between the TV and the eyes should be 2 3 meters, and the room should be properly lit.
Don't watch TV for a long time, overcome picky eating habits, and participate in outdoor activities.

From a physiological point of view, the natural state of human eyelids is drooping, that is, when the human brain no longer controls the eyelid (eyelid) muscles, the human eyelids are drooping, that is, the human eyes are closed. When people sleep, the higher nerve centers of the brain are inhibited, so the muscles that control the eyelids must be inhibited and lose control of the eyelid muscles, so people sleep with their eyes closed. >>>More
