Have you watched “Hurricane” recently? Gao Qiqiang, played by Zhang Songwen, has grown from a kind-hearted fishmonger to a ruthless underworld boss. The cp between him and his sister-in-law Chen Shuting also makes people feel dizzy.
In the latest episode, Gao Qiqiang claimed that he was terminally ill in order to see Chen Shuting for the last time.
What terminal illness? Dry eye … Gao Qiqiang: “At present, there is no medicine that can cure it. Eye drops should be used all the time.”
If you have swollen eyes, dry eyes, tears when you see wind, or even long-term dry eyes, you may also have the same “terminal disease” mentioned by Gao Qiqiang. In recent years, the incidence of dry eye syndrome is on the rise, and the number of ophthalmologists is also increasing. According to statistics, about 17% of people in China suffer from dry eye syndrome.
So many people have dry eye syndrome? I shouted the same question from Chen Shuting in my heart:
The surface of the eye, which has a protective layer of liquid
On the surface of the human eye, there is a layer of liquid called the tear film . The tear film has three layers, which are lipid layer, water layer, and mucus layer from outside to inside. They cover the surface of the eye, lubricate and moisturize, and provide nutrition for the ocular surface tissue.
Every time we blink, a new layer of fluid forms on the surface of the eye to keep the tear film intact. If you don’t blink and let the fluid in the tear film evaporate, the ocular surface will lose its protective layer and we will feel sore eyes .

Normally, the integrity of the tear film can be maintained for 15-45 seconds , which is higher than our relaxed blink rate of 10-15 times per minute. But the newly formed tear film in patients with dry eye tends to be unstable and breaks down quickly , so they need more blinks to maintain the integrity of the tear film.
Many reasons will reduce the secretion of tear film fluid or increase evaporation. If the tear film stability is reduced, it is likely to cause dry eye syndrome.
Do you have these symptoms too?
People with dry eye syndrome often have a range of other symptoms in addition to dry eyes:
-
Sensitivity to light , I can hardly open my eyes when I wake up in the morning;
-
Often feel that the eyelids are heavy or there is something in the eye;
-
Redness or burning of the eyes;
-
Eyes are easily fatigued and blurred, making it difficult to concentrate on study and work;
-
Face the wind and shed tears easily .

Dry eye disease generally does not cause blindness, but it can significantly reduce the quality of life. Long-term dry eyes can easily develop into dry eye disease , so it needs to be taken seriously.
These factors increase the risk of dry eye disease
The etiology of dry eye is complex, and the relevant pathogenesis has not yet been fully clarified, but population studies have confirmed that the following factors will increase the risk of dry eye.
increase in age
Dry eye syndrome is more common in people over the age of 40, because the tear secretion function will gradually weaken with age. In recent years, with the popularization of electronic products and contact lenses, there are more and more young patients.
female
Women are more likely to suffer from dry eye. In women who are pregnant, on birth control pills, and in menopause, dry eye symptoms can be exacerbated by hormonal changes.
Poor ventilation or frequent computer use
Long-term stay in places with poor air circulation or dusty environment, and frequent work with high concentration, such as frequent use of computers, can accelerate the evaporation of tears and cause dry eyes.

long-term medication
Dry eye is an adverse reaction of certain medications, such as blood pressure medications and antidepressants . In addition, some eye drops containing preservatives can reduce tear secretion. If you do not follow the instructions, increase the dosage or prolong the medication time, not only will not relieve dry eye symptoms, but will make the condition worse.
Sequelae of other eye diseases
For example, diseases such as trachoma and infectious conjunctivitis may cause atresia of the lacrimal gland and cause dry eyes.
Ways to Relieve Dry Eyes
Mild dry eye can be relieved by improving lifestyle and using artificial tears. Patients with moderate to severe dry eye need to seek the help of a professional doctor and treat it with drugs or surgery.
improve lifestyle
Contact lenses such as color contact lenses and contact lenses are aesthetically pleasing, but they can aggravate dry eye symptoms. It is recommended that people with related symptoms reduce their use .
Eyeliner and mascara can block the glands in the eyes, causing inflammation in the area around the eyes, and it is recommended to reduce the use of eye cosmetics .
Reduce screen time , close your eyes and rest for a few minutes after using your eyes for 1 to 2 hours, or blink repeatedly for a few seconds, and avoid staying up late.
Air humidifiers can be used in dry rooms.

Dietary Supplementation with Vitamin A
Add foods rich in vitamin A, such as carrots and milk. Lack of vitamin A, the epithelium of the lacrimal gland is prone to keratinization, which will affect the secretion of tears and make the eyes dry.
artificial tears
Dry eye can be relieved with artificial tears. Artificial tears improve ocular surface lubrication and increase moisture . Currently commercially available artificial tears contain no preservatives and are packaged in the smallest package for one-time use, which can not only reduce the damage to the cornea caused by preservatives, but also prevent the contamination of eye drops. It is an ideal artificial tear preparation.
If the dry eye syndrome reaches moderate to severe levels and cannot be relieved by the above methods, it is necessary to use anti-inflammatory drugs under the guidance of a doctor, or undergo surgery .
Eyes are the windows to the soul, I hope everyone can protect their eyes.
