Blowing in the wind will make you cry. What's going on here?

Core Tip: After entering the winter, many elderly people react, blowing in the wind, and their eyes will cry. What's going on here? Is it a sudden eye disease? The doctor pointed out that dry winter is prone to eye diseases such as dry eye, conjunctivitis and tears in the wind, so people must take good protection.

It is understood that under normal circumstances, the lacrimal gland, meibomian gland and conjunctiva secrete a proper amount of tears to form a tear film. By blinking, tears are evenly applied to the surface of cornea and conjunctiva, so as to supplement nutrition, moisten eyes and enhance eye resistance. Due to the cold winter, the external climate becomes dry and evaporation is accelerated, not only the skin will be dry, but also the eyes will be dry, which is easy to cause dry eye.

As for "tears in the wind", it is because of the strong cold wind in winter. People who are sensitive to cold air have their eyes affected by cold air, and their lacrimal gland secretion ability is enhanced. When it is cold, the muscles around the lacrimal canaliculus contract, and some elderly people are more susceptible to this disease.

Prevent 5 kinds of eye diseases in winter:

1. Tears in the wind

Some people with trachoma, chronic conjunctivitis and lacrimal duct inflammation have obstacles in the discharge of tears due to inflammation, narrow or blocked lacrimal duct. Tears will not stop when you meet the cold wind. This situation needs attention. If not treated in time, it will lead to eye infection and cause eye diseases such as keratitis and cataract.

2. Allergic conjunctivitis

In the season of alternating hot and cold, the temperature changes rapidly, which is easy to cause allergic conjunctivitis. Usually patients themselves have allergies. When the weather turns cold, their eyes become sensitive, prone to redness and itching, and there will be slight secretions. Giving patients antihistamines can improve their condition and make them rest more.

3. dry eye

Dry and cold winter is the high incidence season of dry eye, especially for people and students who wear contact lenses. Because of excessive eye use, dry eye is more likely to occur. Therefore, people who have been engaged in computer work for a long time should blink frequently to promote blood circulation in the eyes and moisturize the eyes; When using the computer every 40 minutes, take your eyes off the screen and look far away; People who wear contact lenses should reduce their wearing time, usually apply hot towels to their eyes, don't stay up late, and develop regular living habits; In winter, humidifiers should be used in air-conditioned rooms to increase the humidity in the air and help keep eyes moist.
