How to protect your eyes with a computer at night? Nowadays, people rely more and more on computers and spend more and more time sitting in front of them. So, for people who often use computers, how to protect their eyes when using computers? Let's share how to protect your eyes with a computer at night.
How to protect your eyes with a computer at night 1 1, avoid "staring" and pay attention to frequent and complete blinking. Frequent blinking can reduce the time that eyes are exposed to the air and prevent tears from evaporating.
2. Don't blow the air conditioner for too long, avoid airflow blowing on the seat, and place tea leaves near the seat to increase the surrounding humidity.
3. Eat more fruits, especially citrus fruits, and eat more green vegetables, grains, fish and eggs. Drinking more water also helps to relieve dry eye.
4. Maintain good living habits, get enough sleep and don't stay up late.
5. Avoid operating the computer continuously for a long time, and pay attention to rest in the middle. Usually continuous operation 1 hour, rest for 5- 10 minutes. You can look at the distance or do eye exercises during the break.
6. Maintain a good working posture. Keeping a proper posture and letting your eyes look down at the fluorescent screen can relax the neck muscles and minimize the area of the eyeball exposed to the air.
7. Adjust the screen distance position. It is suggested that the distance is 50-70cm, and the fluorescent screen is slightly lower than the eye horizontal position of 10-20cm, showing a downward viewing angle of 15-20 degrees. Because angle and distance can reduce the demand for refraction and reduce the probability of eyeball fatigue.
How to protect your eyes with a computer at night? Two common ways to protect eyes with computer.
1. Eating more nutritious food can effectively protect your eyes.
1. 1, vitamin a and carotene
Without vitamin A, the human body's adaptability to light and darkness will decline, in addition, it will also lead to dry eyes, poor rotation, and even white spots, corneal softening or ulcers in severe cases.
Supplementary sources: liver, egg yolk and whole milk. Carotene in plant food can be converted into vitamin A in the body, so it is also a good supplementary source. All kinds of dark green leafy vegetables, orange vegetables and fruits contain carotene. The darker their color, the higher their carotene content.
1.2, vitamin b group
Vitamin B2 is called "cosmetic vitamin". Without it, eyes are prone to fatigue, fear of light and tears. In addition, vitamin B6, pantothenic acid and other B vitamins can also help the eyes to eliminate fatigue.
Supplementary sources: egg yolk, milk, animal offal, lean meat, beans, all kinds of coarse grains, whole wheat food, etc.
2. Exercising eyeballs can effectively relieve eye fatigue.
If you have been staring at the computer screen for an hour, you need to do some eye movements to relieve eye fatigue. For example, look up and take a deep breath at the same time, then move your eyes back to the middle, take a deep breath, repeat this for three times, and finally continue the same action on the lower side, left side and right side.
Blinking after work can protect your eyes.
Blinking can promote the eyes to secrete tears, and apply the tears containing various components evenly on the surface of the eyeball to keep the eyes moist. Many people are too focused on their work and stare at the computer screen for a long time without blinking, which leads to dry eyes and discomfort. Taking time out from busy work and blinking a few times will help clean the surface of the eyes, which is equivalent to giving them a massage.
4. Taking breaks at work can relieve eye fatigue.
Professional women who use the computer continuously for 6~8 hours should take a rest every 1~2 hours and keep their eyes away from the computer 10~ 15 minutes; After working 1 hour, it is best to leave the computer screen and stare at the distant target until you can see it clearly, and then keep 10 second.
Diseases prone to long-term use of computers
Long-term use of computer is prone to tendon sheath cyst, which is more common in women and adolescents and occurs near joints or tendon sheaths. The incidence of wrist dorsum, wrist flexor tendon and instep is the highest. Chronic injury increases synovial fluid in synovial cavity, leading to cystic hernia or mucinous degeneration of connective tissue, which is an important cause of the disease. People who have been dealing with computers for a long time, holding the mouse for too long, or holding the mouse incorrectly, will cause damage to the synovial cavity of hand joints and cause diseases.
Remind everyone not to use computers for a long time. If you need to surf the Internet for a long time, you should also rest for 5 to 10 minutes every hour. During the break, do indoor sports, do soft exercises or local massage, exercise the neck, upper limbs and wrists to enhance flexibility and muscle strength.
Dietary norms for people who often use computers.
1, to ensure the rich nutrition of dinner, fish and bean products have the function of nourishing the brain and should be included in the dinner menu. It is not advisable to eat instant noodles to fill your stomach in the middle of the night, so as not to get too angry. It is best to fill your hunger with fruits, bread and porridge.
2. Pay attention to hydration during staying up late. You can drink medlar jujube tea or chrysanthemum tea, which is nourishing and has the effect of removing fire, and can also reduce stress and improve eyesight.
3, remember to remove makeup before staying up late, or wash your face first, so as to avoid thick powder or oil stains, and face acne under the suffering of staying up late.
4. After staying up late, the best protection measure is naturally to "make up for lost sleep". It is important to take a nap at noon the next day, but don't make up a lot of sleep during the day, which is easy to break the original biological clock. No matter how late you stay up, you should get up on time the next day and sleep more at night.
5. On the issue of internal adjustment, you should usually eat more foods that are helpful for anti-oxidation, such as foods containing vitamin A, vitamin C and vitamin E ... Yang Fei often puts A, C and E together. Because they are really a super antioxidant combination! Rich vitamin C can be taken from various vegetables and fruits, especially fruits, because it is water-soluble.
How to protect your eyes with a computer at night 3. How do computer people pay attention to protecting their eyes?
First, the computer screen should pay attention to the size, contrast, clarity and other configurations, and the screen viewing angle should be lower than the horizontal line 10-30.
Second, contact lenses should be used less for myopia, because wearing contact lenses at close range will strengthen the adjustment of eyes and make them tired easily.
Third, when operating a computer, whether you choose natural light or other lighting equipment, you can't make the screen reflect light and stimulate your eyes.
Fourth, be careful not to operate the computer for too long, and look far between jobs. Green objects also help to relax the ciliary muscles of the eyes moderately.
Tips for internet users' vision maintenance
1: Adjust the computer screen
Adjusting the contrast and brightness of the screen by self-luminous objects can help reduce the eye problems caused by computers, because the screen flashing too fast or too slow will cause eye discomfort.
Screen scanning frequency should be greater than 60 times per second. If the scanning frequency is too slow, it will cause the screen to flicker and further cause eye discomfort.
Suggestions for improvement: Adjust the contrast and brightness of the computer screen to keep the scanning frequency greater than 60 times per second.
Step 2: Adjust the eye position. The average person's normal reading angle is about 40. Generally speaking, looking directly at the computer screen is an unnatural angle, so it is easy to cause fatigue, sore eyes and even headaches.
Suggestions for improvement: Adjust the height of the seat and the angle of the computer screen so that the center of the screen is between 7- 10 under the eyes.
The third step: avoid reflection and take the principle of seeing clearly and being comfortable. Also pay attention to the light sources that cause reflection, such as lights, fluorescent lamps, sunlight, reflective surfaces and illuminants, and the position of the screen so that it can't see reflection.
In the indoor light section, generally speaking, indoor light should be three times the brightness of the screen.
Step 4: Suggested improvement method for selecting computer glasses: Users of general glasses frames should prepare a pair of computer-specific glasses, and ask ophthalmologists to provide special prescriptions according to their usual distance from watching the computer. The lens itself should be dyed light rose red, and the material should be multilayer.
Contact lens wearer
Contact lens consumers are prone to dry eyes and discomfort due to the influence of working environment. Usually pay attention to blink more or keep your eyes moist with comfort liquid.
Especially for modern office workers, they often work in air-conditioned rooms with dry air, and their eyes often feel dry. Comfort liquid should be used regularly before eyes feel dry.
Suggested improvement method: Comfort liquid can be improved by application. Consumers should apply comfort liquid regularly for 3-4 hours or before drying, such as watching computer or reading books, or increase the frequency of applying comfort liquid during drying, and keep the habit of applying comfort liquid at least once every morning, noon and evening.
Step 6: 3Bs vision care Formula Remember to keep the 3B formula and easily carry out the vision care:
First, blink: blink more.
Staring at the computer for a long time will reduce blinking and lead to dry eyes, so blink more and keep your eyes moist.
Second, breathe: take a deep breath.
Focusing on the computer screen for a long time often leads to a temporary stop of breathing, so keep breathing smoothly and relax.
Third, rest: rest.
Every time you work or read 10 minutes, look far 10 seconds to relax your eyes. Every time you work or read 1 hour, you should rest for 5 minutes, and you can do some eye exercises to rest your eyes.
You should get up and have a cup of tea every 2-3 hours after work or reading.
