Good eye hygiene and upright posture are the first steps to protect eyes, relieve eye fatigue and reduce the influence of monitoring radiation. Let's see what to do:
1, don't use the computer for a long time. Generally, every hour of computer operation requires a rest 10 minute. Taking a rest or doing eye exercises and watching green vegetation are conducive to relaxing eye muscles. Use eye drops to prevent dry eyes and keep them moist to a certain extent.
2. Keep your eyes at a distance of more than 50 cm from the screen, preferably at a viewing angle of 20 degrees. The distance between the presentation input personnel, the document and the computer monitor screen should be reduced, thus reducing the fatigue caused by the changing targets in the eyes. 3. Blink more when using the computer to increase the secretion of eye lubricants and enzymes and keep your eyes moist.
Washing your face often can reduce the harm of radiation to human body.
5. Drink green tea every day. Tea lipopolysaccharide can improve human hematopoietic function, enhance human immunity and reduce the influence of radiation. 6. Eating more fresh vegetables and fruits can prevent eye diseases such as dry cornea, dry eyes, decreased vision and even night blindness. If the eyes are uncomfortable and the symptoms are not relieved after a long rest, you need to go to the hospital for a physical examination immediately. With a good environment for using computers, eye protection is very important. 1, machine room, regularly ventilated. For air-conditioned rooms, attention should be paid to ventilation. A lot of carbon dioxide can cause dizziness, headache and other symptoms. 2, the computer should be placed on the side or rear window, the ambient light should be soft, and the brightness of the computer monitor should be adjusted appropriately. Rooms using computers can be equipped with blinds and curtains. 3. The indoor temperature of the computer is 2 1 degree and the humidity is 60 degrees. You can put some plants indoors, which can not only keep the room temperature, but also supplement oxygen.
The eye injuries that computer users of computer monitors often face mainly come from it, so it is very important to choose a good display effect for eye protection. The radiation of the monitor is the killer of human health, so the monitor with lower radiation should be selected. In the computer display industry, there are many certification standards, such as MPR, TCO92, TCO99 TCO99 certification, which are very strict. TCO99 certified monitors are less harmful to the body. In addition, some show that big manufacturers have better quality and ergonomic design, which may be smaller and more expensive, but they are still very cost-effective, and spend money on health. If there is no problem with funds, you can also consider using LCD (liquid crystal display), which has low radiation and almost no flicker, which is very good for people's health. The brightness of the display screen should not be set too high, because too high brightness will cause greater irritation to the eyes and make them tired quickly. In Windows, you should also pay attention to the settings on the desktop. The RGB primary colors of wallpaper are balanced, so the color of wallpaper is softer to reduce the stimulation to human eyes. Articles with high refresh rate and low refresh rate have a lot of contact with healthy people's eyes. Low refresh rate will make eyes tired and unable to work for a long time. Generally speaking, 85 Hz is only harmful to human eyes. Set the refresh rate in Windows. Generally, some brand names are displayed. After installing the driver, you can click the "Advanced" button and click the "Settings" tab of "Display Properties". Then set the refresh rate of the monitor. The higher the monitor can bear, the better.
Of course, the most important thing is to combine work and rest. After all, health is the capital of revolution. Finally, teach you how to protect your eyes. You stand by the window and look at the distant scene, then slowly turn to recycling, and finally look at the four corners of the window, and then stick to the four corners of the window clockwise and do it counterclockwise for five times. Finally, close your eyes and take a deep breath. All right, it's done. Following your eyes will make you feel more comfortable and your body will be very comfortable. We can try. I hope everyone's eyes are protected like me. My eyes are now 5.2.

After a long time, it is easy to cause dry eye, serious corneal damage, and even.
In addition, a small fluorescent spot on the computer screen, eyes must constantly adjust the focal length to ensure clear vision, eye muscles will be too tired for too long.

Such patients, the early test results often can't find anything wrong, but in the long run, they may lose healthy eyes. For young people, turning off the computer for a long time may lead to spasm, hyperopia and true myopia.
