What causes dry eyes in children?

Children's eyesight must be protected, but recently my child has been crying frequently, so I have no choice but to let him watch some TV programs. However, I found that there were certain problems with his eyes. So what is the reason for dry eyes in children? Facts have proved that many children have problems with their eyesight, but parents do not deliberately protect their children's eyesight. This is wrong. So it is best not to let children watch electronic products frequently. Let us take a closer look below.

Dry eye syndrome is a general term for a variety of diseases caused by abnormal tear quality or quantity or abnormal dynamics due to any reason, which leads to decreased stability of the tear film and is accompanied by eye discomfort and/or ocular surface tissue lesions. Also known as keratoconjunctivitis sicca. Common symptoms include dry eyes, easy fatigue, itchy eyes, foreign body sensation, burning pain, sticky secretions, fear of wind, fear of light, and sensitivity to external stimuli. Sometimes the eyes are too dry and the basic tears are insufficient, which stimulates reflex tear secretion and causes frequent tears. In more serious cases, the eyes will be red, swollen, congested, keratinized, and the corneal epithelium will be broken with filaments attached. This damage can cause corneal and conjunctival lesions over time and affect vision.

What causes dry eyes in children? Normally, the tear points are immersed in the tear lake and touch the bulbar conjunctiva. Even if the patient looks up, the lower tear points will not be seen without opening the lower eyelid. This close contact is a prerequisite for maintaining normal tear absorption function. The location of the lacrimal puncta can be observed through visual examination. Even though the tear ducts are well flushed, it is difficult to divert tears, which causes tearing in the wind. There are many causes of lower lacrimal punctum ectropion, such as congenital abnormalities, scar ectropion, senile eyelid skin relaxation, and facial nerve paralysis. Especially very mild facial nerve paralysis is often overlooked, and it can be discovered by asking the patient to smile.

So this is the reason why children have dry eyes. There are congenital and acquired causes. The congenital ones are some genetic diseases, and the acquired ones are due to not protecting their eyes and often seeing irritating objects. Therefore, it is recommended that parents should urge their babies not to watch TV too often, but to read more books.
