The damage to the eyes to play with the air conditioner is a double crit doctor telling you to prevent eye prevention.

On the hot summer, playing with mobile phones and computers while blowing air conditioners. It is very pleasant to think about it. But be careful, blowing air -conditioning to play mobile phones for a long time, damage to the eyes is double crit, or it may cause the eyes to suffer from "air conditioning disease" -the dry eye disease. According to Professor Wang Jianming, the dry eye special disease clinic team of the Second Affiliated Eye of Xi'an Jiaotong University, the air -conditioned room is generally relatively dry, and the screen radiation can accelerate the evaporation of tears. It will cause some eye discomfort, such as dry eyes, burning sensation, sore eye, itching, fear of light, and blurred vision, etc., can also be accompanied by emotional irritability, fatigue, and difficult attention.

In normal state, people's eyes blink 15 ~ 20 every minute, that is, every 3 seconds, the eyes have an unsteady blink of an eye. This process is called "instant eyes". At each complete instant eye, the upper and lower eyelids are completely covered with the surface of the eyeball, allowing the tears to be evenly distributed on the cornea and conjunctiva, keeping them moist, helping the tear circulation and cleaning the cornea, and allowing the eyeball to rest at least 0.2 seconds. The electronic screen design itself is a kind of stimulus to the eyes, which causes an effective instant eye when staring at the screen. The number of blinks per minute is reduced by half or even reduced to 1/3. Moreover, the screen will continue to jump out of new stimuli points, and the eyeball will be attracted to the past. From one stimulus point one after another to another stimulus point, during the movement, the eyes continue to be tense, these on the screen are on the screen Design causes uneven distribution of endometrial tears and increases the evaporation of tears. And the latest research found that excessive use of the screen will eventually affect the secretion of lacrimal glands and the amount of tears will be damaged.

In the summer, the temperature is high, the air in the air -conditioned house is relatively dry, and the air flow is poor. The water in the tear film on the surface of the eyes is easy to evaporate. Originally high temperature, it was easy to dry, plus the air conditioner and wetting effect, and the use of computers and televisions for a long time, the instant decrease was undoubtedly worse. Eye. At the same time, because the air -conditioning filter is easy to accumulate dust mites, it is easy to cause allergic conjunctivitis and bondingitis, and aggravate dry eye symptoms.

So what should I do if I want to blow the air conditioner and want to play mobile phones? In this regard, the doctor tells you to prevent eye prevention:

1. Regularly clean the air conditioner to prevent the filter from accumulating dust mites.

2. The temperature of the air conditioner should not be set too low. Generally, the appropriate temperature is 25-26 ° C, and the temperature difference between indoor and outdoor temperature is best not exceeding 8 ° C.

3. Cold air generally sinks. When using the air conditioner, the air outlet is as much as possible to avoid the cold air blowing straight.

4. You can put a pot of water or humidifier in the room to increase the air humidity, and pay attention to opening the window.

5. In the air -conditioned room, you have to rest for 5 to 10 minutes every 1 hour of working in the air conditioner, and often blink to reduce the time when the eyeball is exposed to the air, avoid the evaporation of tears, and avoid "eye -catching."

6. Reduce wearing contact lenses.

7. Drink plenty of water, replenish water, eat more vegetables and fruits. Vitamin A can prevent and relieve corneal dryness. Vitamin C can effectively antagonize cell oxidation. Vitamin E can reduce cholesterol. Therefore, daily diet should be diversified and rich in varieties, and irritating foods and fried foods should be avoided.
