Can't you avoid it?

With the progress of society and the development of science and technology, people's life rhythm is getting faster and faster, and the strength of the eyes is getting greater, especially the popularity of electronic products such as smartphones and computers, which increases the burden on the eyes. Many " "In office workers" have dry eyes such as dry eyes and visual fatigue. How exactly does dry eyes come from? Why are "office workers" prone to dry eyes? How to prevent it?

There is a tear film on the surface of the eyeball

Under normal circumstances, the surface of our eyeball cornea will cover a layer of tear film. This layer of tear membrane is mainly divided into three layers of structure, from the outside to the inside in the lipid layer, water liquid layer and adhesive protein layer. They jointly ensure the stability of the tear membrane on the eye surface and play a moist and protective role in the eye surface.

An abnormalities in any layer of structure will affect the stability of the tear membrane. Therefore, when this layer of tear membrane cannot be stable on the eye meter, the eye meter cells that lose the protection of the tear membrane will be damaged, and the eye drying, foreign body sensation, burning sensation, and lighting are appeared. Symptoms and other symptoms, at this time, it was developed.

Common causes of dry eyes

1. Look at the screen for a long time

For "office workers", electronic products such as mobile phones and computers have long become a must -have tool for work, and most of the day face the electronic screen. When looking at the mobile phone and the computer, the attention is highly concentrated, often the number of blinks decreases, and the exposure of the eye surface increases, and the tears evaporate too quickly. For a long time, the eye dysfunction can also be caused, which reduces the outermost lipid of the "tear film" and further accelerates the evaporation of tears. The light from the screen terminals such as the computer will stimulate the eyes and the eye meter cells will be damaged, which will further decrease the stability of the tear membrane. Looking at the electronic screen for a long time, the eye muscles continue to shrink, which can cause visual fatigue symptoms.

2. Wear contact lenses

It is inconvenient to wear frame glasses. Wearing contact lenses has become a major choice for myopia. In addition, many beautiful girls like to wear "beautiful pupils" make their eyes look bigger and more powerful. Long -term unreasonable wearing contact lenses will reduce corneal sensitivity and reduce the number of blinks. The decrease in the number of blinks will cause disorders of meibomian gland glandular lipids. Tears evaporate too fast because it loses the protection of fat. The unqualified contact lenses will also aggravate the mechanical friction of the eye meter and damage the eye meter structure.

3. Dry working environment

Most of the offices will turn on air conditioners, large airflows, low air humidity, which will accelerate the evaporation of the eyes and tears and increase the symptoms of dry eye.

4. mental stress, anxiety

Due to the high work pressure, many "office workers" are prone to tension and anxiety, which can be adjusted in the short term, but the long -term abnormal psychological state can easily lead to abnormal nerve function, and the reduction of the pain threshold will increase the discomfort of the eye. Even if the eye meters are not severe, they still feel strong, further aggravate anxiety, and a vicious circle occurs.

5. Bad habits and behaviors

Poor eating habits, lack of outdoor sports, lack of sleep for a long time, long -term driving, abuse of eye drops, etc. are all risk factors that "office workers" are prone to dry eyes.

What to do if there is dry eyes

Dry eyes is a chronic eye meter disease caused by multiple factors. If you have dry eyes, you must first correct the risk factors that cause dry eyes as much as possible. Secondly, regular treatment is performed under the guidance of a doctor.

1. Reduce the use of electronic products such as mobile phones and computers. Generally, take a break for about 1 hour with your eyes for 15 minutes. You can close your eyes. You can practice blinking, or you can overlook the window. When using the computer, keep the correct posture. It is recommended that the distance from the screen is 50 ~ 70 cm, and the display position is 15-20 degrees at the level of sight. Avoid watching your phone while walking or lying down.

2. Reduce the use of contact lenses and wear frame glasses as much as possible.

3. Develop good living habits. Ensure sufficient sleep and avoid staying up late. Exercise appropriately. Keep a relaxed and happy mood. Light diet, eat less spicy, fried, irritating foods, drink less alcohol, eat more vegetables and fruits rich in vitamin A.

4. Practice more blink. Blink can make tears evenly on the corneal and conjunctival surface, keeping the eyes moist. In order to facilitate the discharge of meibomian glands, you can usually do blinking training, and you should blink 10 to 20 times per minute.

5. Try to improve the working environment, avoid direct air -conditioning air outlets, increase environmental humidity, and use humidifiers reasonably.

6. Appropriate heat compress. Hot compresses can improve the meibomian glands. It is recommended to apply hot compresses 1 or 2 times a day, 10-15 minutes each time, and the temperature is controlled at about 40 ° C.

7. If the symptoms of dry eye after trying the above methods still cannot be relieved, do not use eye drops at will. Please go to the eye department of the regular hospital in time to receive professional diagnosis and treatment.

The error operation aggravates dry eyes

Error operation: abuse of eye drops.

As soon as many young people have eye discomfort, they will buy some eye drops, especially some "net red" eye drops. Although these eye drops can alleviate the dry eyes in a short period of time, if it is abused for a long time, it is tantamount to drinking and quenching thirst. Because most drops of eye fluid contain preservatives, if long -term use will damage eye meter cells, which will affect the formation of tear membranes, which will increase dry eye.

Error operation: Incorrect hot compress.

First of all, we should know what the main purpose of hot compress is. The hot compress is to melt the clogging meibomian glands through heat, improve the meibomian glands, and make the outer layer of the outer layer of the eyes of the eye surface have a healthy "oil" to reduce the evaporation of the tears. Some patients listened to the doctor's advice and felt that hot compresses were good, and they always insisted on everything. As everyone knows, it is too late, and some cases cannot be applied. For example, acute inflammation such as redness and swelling and secretions in the eyes, you must not apply hot compresses. In addition, it is not advisable to compress when wearing contact lenses. Moreover, those with sensitive skin and skin injury around the eyes should not be applied. The steam eye mask that young people like to use to alleviate the dry eyes are clear. Many people think that the higher the temperature, the longer the duration, the better the effect, and even wearing an eye mask to sleep. This is wrong. In order to avoid epidermal damage, the doctor suggested that the suitable hot compress temperature is 40 ° C, not exceeding 45 ° C, and the hot compress time is best not to exceed 15 minutes.
