The eyes are the windows to our hearts. A normal person uses his eyes all the time, and it is hard to imagine life, work and study without them! For those of us who often face computers, computer screens do more harm to human eyes. If you don't pay attention to protection, the injury will be more serious. Everyone will say to protect their eyes, but not many people actually do it, and more people don't even know how to protect their eyes. Now there are more and more products about eye care in advertisements, but it is better to take preventive measures. So how to protect your eyes? Let's take a look at this eye protection manual for IT people! Good eye habits can make the use of eyes healthy, and correct posture is the first step to protect eyes, which plays a very important role in relieving eye fatigue and reducing the radiation influence of monitors. Let's see what to do: 1, don't use the computer for long. Usually, every time the computer operates 1 hour, it needs to rest 10 minute. When resting, you can overlook or do eye exercises, and watching green vegetation is conducive to relaxing eye muscles. Eye drops can also prevent dry eyes and keep them moist to some extent. 2. Keep your eyes at a distance of more than 50 cm from the screen, and it is best to look down at 20 degrees. For those who need to input the manuscript, the distance between the manuscript and the computer monitor screen should be reduced to reduce the fatigue caused by eyes constantly changing targets. 3. Blink more when using the computer, increase the secretion of eye lubricants and enzymes, and keep your eyes moist. 4, wash your face often, can reduce the harm of radiation to the human body. 5. Drink green tea every day. Lipopolysaccharide in tea can improve the hematopoietic function of human body, enhance the immune ability of human body 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. 7. If there is eye discomfort, the symptoms can't be alleviated after a long rest, and you need to go to the hospital for a doctor's examination immediately. A good computer environment is also essential for eye protection. 1, the computer room should be ventilated frequently. For air-conditioned computer rooms, attention should be paid to ventilation. A lot of carbon dioxide can cause dizziness, headache and other symptoms. 2. Don't put the computer opposite or behind the window. The light in the surrounding environment 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 optimal temperature of the computer room is 2 1 degree, and the humidity is 60 degrees. Some plants can be placed indoors, which can not only keep room temperature, but also supplement oxygen. Computer monitor is often faced by computer users, and most of the damage to eyes comes from it, so it is very important to choose a good monitor to protect eyes. The radiation of the monitor is the killer of human health, so you should try to buy a monitor with low radiation. In the computer monitor industry, there are many certification standards, such as MPR, TCO92, TCO99 and so on. Among them, TCO99 certification is very strict, and the display certified by TCO99 is less harmful to human body. In addition, the monitors produced by some big factories are of better quality and more ergonomic design, which may be more expensive, but it is still cost-effective to spend money on health. If money is not a problem, you can also consider using LCD (liquid crystal display), which has lower radiation and almost no flicker, which is very good for people's health. Don't set the brightness of the display too high, because high brightness will cause great irritation to the eyes and make them tired quickly. In Windows, you should also pay attention to the desktop settings. The color of wallpaper should be the balance of RGB primary colors, which can make the color of wallpaper softer and reduce the stimulation to human eyes. Fourthly, the refresh rate of the display is also closely related to the health of human eyes. Low refresh rate will make eyes tired quickly and can't work for a long time. Generally speaking, 85 Hz is less harmful to human eyes. Set the refresh rate in Windows. Generally, after installing drivers for some well-known monitors, you can click the "Advanced" button in the "Settings" tab of "Monitor Properties". Then set the refresh rate in the monitor. If the monitor can bear it, set it as high as possible. Of course, the most important thing is to combine work and rest. After all, health is the capital of revolution. Finally, I'll teach you a way to protect your eyes, that is, stand by the window and watch the scenery for half a minute, then slowly take back your sight, finally look at one of the four corners of the window with your eyes, then look at the four corners of the window clockwise one by one, and do it counterclockwise five times after five times. Finally close your eyes and take a deep breath. All right, it's done. Soon you will feel much more comfortable with your eyes and your body. You can try. I hope you can protect your eyes like me. My eyes are 5.2 now, hehe ~ ~ ~ References:
My computer teacher gives me advice on how to protect your eyes every day. People who use computers for a long time generally suffer from dry eye, that is, they are prone to dry eye, jealousy and fatigue. Experts believe that this is closely related to not blinking when using a computer. When people stare at the fluorescent screen, the number of blinks will decrease invisibly, from 20-25 blinks per minute to 5- 10 blinks, thus reducing the secretion of tears, the lubricant of the eyes. At the same time, the eyeball is exposed to the air for a long time, which makes the water evaporate too fast, causing dry eyes and discomfort. It is easy to cause dry eye for a long time, and even seriously damage the cornea. In addition, the computer screen consists of small fluorescent spots, and the eyes must constantly adjust the focal length to ensure a clear field of vision. Over time, the eye muscles will be too tired. Electromagnetic waves, ultraviolet rays, radiation, dazzling colors and infrared rays on the computer screen can also irritate the eyes, causing dryness, fatigue, ghosting, blurred vision and even head and neck pain. Because artificial tears can properly replenish and store tears, artificial tears products can be used appropriately to alleviate and eliminate eye discomfort caused by dry eye. The most important thing to prevent dry eye is to pay attention to healthy eyes: 1. Blink more when using the computer and rest every 1 ~ 2 hours 15 minutes; 2. The fluorescent screen should be under the line of sight; 3. In order to avoid reflection and unclear, don't put the computer on the opposite or back of the window; Don't watch the computer in the dark, because black and white contrast is harmful to your eyes.
