1. Keep your eyes at a distance of 50-70cm from the screen, and look down at 20 degrees.
2. Don't use the computer continuously for a long time. You usually need to rest every 1 hour 10 minute. You can overlook or do eye exercises during the break.
3. Looking at green plants is good for relaxing eye muscles, and eye drops can also prevent dry eyes and keep eyes moist to some extent.
4. Blink more when using the computer, increase the secretion of eye lubricants and enzymes, and keep your eyes moist.
Washing your face often can reduce the harm of computer radiation.
2. Drink more chrysanthemum tea
Chrysanthemum tea is a good drink to protect your eyes! Chrysanthemum tea can eliminate eye edema and fatigue. If you drink too much water before going to bed, your eyes will swell like pandas when you get up the next morning. There is a folk method that can effectively relieve it, that is, apply the tea juice of cotton dipped in chrysanthemum tea around the eyes, which will soon eliminate this edema. Chrysanthemum has a good effect on treating eye fatigue and blurred vision. Drinking a cup of chrysanthemum tea can eliminate the symptoms of eye fatigue. If you drink three or four cups of chrysanthemum tea every day, it will also help to restore your vision. Lycium barbarum is added to chrysanthemum tea, both of which are Chinese herbal medicines for eye protection. The brewed tea is the famous "Chrysanthemum Qi Tea". In particular, students often get tired after reviewing their lessons on sunny nights. People with myopia often feel dry eyes. Drinking chrysanthemum tea often can improve their eye discomfort.
Put a cup of hot water next to the computer.
Do friends also have dry eyes and blurred vision? This is a common problem of many "computer families"! Internet addicts who like to stay up all night surfing the Internet do more harm to their eyes. Doctors suggest that people who often use computers should investigate the screen until their eyes are lower than the eye level 10 to 20 cm, which can reduce the chance of eyelid lifting. In addition to giving your eyes more rest, you should also blink frequently to moisten your eyes, because the average computer worker blinks 22 to 7 times a minute when focusing on the screen, which will make the tears on the surface of the eyeball unconsciously evaporate too much, so dry eye will be aggravated. Put a cup of hot water next to the computer to increase the surrounding humidity to relieve eye discomfort. One more maintenance is one more health!
4. Cactus, the bane of computer radiation
Cactus can attack bad people, and there is another advantage! I heard that putting a cactus in front of the computer desk can help reduce radiation; Because the cactus is in the strong sunlight.
Local growth, so the ability to absorb radiation is particularly good, those sedentary computer students quickly find a cactus to protect their eyes. As for how big you want, it depends on your needs!
The brighter the computer environment, the better.
The doctor pointed out that when using the computer, the surrounding environment should not be too bright, and do not rely on the window to hit the computer, otherwise glare and reflection problems will easily occur, causing eye fatigue and soreness. This kind of "computer vision syndrome" and wrist and back injuries caused by long-term use of computers have jumped to the first place among occupational diseases in the United States and must be paid attention to.
Eye protection is an important life project that runs through our work and life. Let's protect the windows of our hearts from now on and make them clear and bright forever!
Let the light outside the window and the indoor light reflect the light on the screen, which will reduce the contrast and affect the visual effect. It is best to install a special micro filter or goggles in front of the screen, which can reduce the electromagnetic radiation of the computer screen (CRT display) and protect the eyes, especially for users who wear glasses. According to research, when users' glasses with metal frames are irradiated by computer screens, the glasses' frames will produce secondary radiation, which is far more harmful than the direct radiation of the display. When there is dust on the screen, it must be wiped with computer-specific wiping paper to increase visibility.
When inputting documents, the data and words to be input should be as close as possible to the fluorescent screen to reduce the rotation of the neck and eyes and the change of attention. Enlarge the font size and line spacing displayed on the big screen to facilitate reading and reduce the burden on the eyes. At the same time, the display ratio can be increased. For example, in Word, the display ratio can be adjusted to 150% or 200%, so that the text displayed on the screen is larger, which can reduce the fatigue of eyes.
Blinking more can moisturize your eyes (don't stare at your eyes all the time when using the computer, it will hurt your eyes too much) and prevent your eyes from being dry. If your eyes are uncomfortable, you'd better see an ophthalmologist. Don't order eye drops yourself, especially those with antibiotics. Long-term use is more harmful to glasses.
Give your eyes a rest. Rest every 2 hours when using the computer 10 ~ 15 minutes. At this time, you can look out of the window from a distance. As long as you don't focus on using your eyes at close range, you will have a rest effect. Hot compress eyes or massage around eyes. Cover your eyes with a hot towel or handkerchief (and close your eyes at the same time), 1 ~ 2 times a day, and each hot compress lasts about 10 ~ 15 minutes. You can also gently press the bones around the eye socket with your thumb, start from the inner side above the eye socket, massage along the bones to the outer side of the eye, and then move in the direction from the fundus to the nose, which is also conducive to the rest of the glasses and reduces eye fatigue.
Finally, you need to pay attention to the distance between your eyes and the computer screen. Keep the distance between eyes and 14 inch screen at least 60 cm, and 15 inch should have a buffer of 70 cm. 17 inch should have a buffer distance of 70 cm. In addition, it is best to keep a low viewing angle 15 to 20 degrees when watching the computer, which is helpful to reduce the exposed area of the eyeball. Office workers who stare at the computer every day, if they don't pay attention to the self-protection of their eyes, will not only make their eyes tired, but also seriously affect their whole body, resulting in "computer fatigue syndrome." In addition to improving the quality of computer screens and adopting various self-care methods, we should also pay attention to the placement of computers, the adjustment of desks and chairs, and the adjustment of sitting posture.
The best distance to operate the computer should be kept at 50 cm -60 cm. If the screen size is large, the distance can be extended to 70 cm as appropriate. If the distance is too close, it is easy to be damaged by radiation, and it is also easy to cause myopia or deepen myopia; And the distance is too far, you need to stretch your shoulder arm to hold the mouse, which will cause shoulder muscle pain for a long time.
It is best to put the computer at a height of 30 degrees below the horizontal line of sight, and the screen is slightly tilted upwards 10 degrees. On the one hand, it can reduce the exposed area of cornea and relieve dry eye; On the other hand, it can relieve the tension of neck muscles and reduce the occurrence of cervical spondylosis.
The height of the seat is best to bend the knees 90 degrees or lean forward slightly, and the feet should be flat on the ground. The seat is too high and the legs are suspended, which will oppress the blood circulation; But if the seat is too low, the legs will curl up, pressing the internal organs and affecting the gastrointestinal function. The backrest should lean forward to make the spine straight, otherwise bending for a long time will not only oppress the internal organs, but also make people hunch back prematurely.
I suggest you sit facing the screen and don't tilt the computer to one side, otherwise your eyes will be unbalanced for a long time. Not only that, the neck, waist, shoulders and wrists are also excessively bent and strained. The working environment should also pay attention to good ventilation, reasonable light and moderate humidity. There should be a certain space behind the computer, so that when you look at the computer, there is room for expansion.
