It s best to play with the computer for a few hours without damaging your eyes

Experts suggest that when using a computer, it is best to keep the distance between the eyes and the computer phosphor screen at least 60 cm, so as to minimize the damage to the eyes caused by the computer. A good working posture is also very important in computer operation, maintaining an optimal posture with both eyes at eye level or slightly looking down at the phosphor screen, which will ease the neck muscles and minimize the area of the eyeball exposed to the air.

Netizens who operate the computer continuously for a long time should also pay attention to: avoid operating the computer continuously for a long time and pay attention to the rest in between. Usually after 1 hour of continuous operation, you should take a break for 5 to 10 minutes.

When resting, you can look into the distance or do eye exercises; Create and maintain good working conditions. If you have dry eyes, redness, burning or foreign body sensation, heavy eyelids, blurred vision, or even eye pain or headache, and there is no obvious improvement after rest, then you need to go to a regular optical store for optometry, check your eyesight or go to the hospital to see a doctor. In addition, tears themselves are the best lotion, and the best way to improve dry eyes is to blink from time to time.

It is recommended to spend 3 hours, one hour in the morning, one hour in the afternoon, and one hour in the evening. The eyes can't keep staring at the screen, and the eyes blink and turn a lot!

It's better to play less, and then the time can't be long, such as half an hour eye rest for 10 minutes, massage, and look at distant places, so that you can play for a longer time a day, and then the damage is less.

This varies from person to person, and generally rests for an hour or two when your eyes are sore

It won't hurt your eyes for less than three hours straight, and you can play for a while and take a break.

Preferably 2 hours, moderate is fine.

Look at the computer for 1 hour and take a 10-minute break.

The most important thing is to give your eyes plenty of rest. Experts suggest that the brightness displayed on the computer screen should be about 3 times that of the surrounding light, the upper end of the screen is slightly lower than the line of sight 10-15 degrees, and the distance between the eyes and the computer screen should be kept at more than 60 cm; For every 1 hour of work in front of the computer, you should take a 10-minute break, close your eyes, massage the muscles around your eyes with your hands, or look at the distant scenery. You can also use some artificial tears to moisturize your eyes, or deliberately increase the number of blinks. In addition, you should also eat more foods rich in vitamin A, such as carrots and animal liver.

Hello, it depends on your age. The younger you are, the more damage you have.

For example, if you are an elementary school student and four hours a day, you are likely to reach high myopia within a few years.

For junior high school students, myopia generally deepens. High school students will also deepen.

After the age of 18, the change in vision is very small, and the computer will only slightly deepen myopia for four hours a day.

For young people over the age of 22, four hours a day with a computer will not deepen myopia. There is almost no harm. An adult's eye can withstand prolonged use of a computer.

However, with so much time spent on the computer every day, perhaps the more important damage is not the eyes, but the waste of time and leading to obesity, etc.

The spectrum of the computer's LCD screen contains a large amount of blue light, which has been confirmed by the optometry community to be the most harmful cause to the eyes.

According to the survey, half of working women between the ages of 20 and 50 use digital products for more than 11 hours a day. And due to the exposure to too much blue light, most women suffer from varying degrees of insomnia and neurasthenia.

The blue light contained in white light can strongly inhibit melatonin, which can hinder sleep and dreaming, and disrupt the body's circadian rhythm. In addition, when people watch the computer or TV at night, it will not only bring a burden to the eyes, but also make the brain feel excited, and it is not easy to fall asleep, thus reducing the quality of sleep.

Therefore, it is an effective way to protect your eyes before the computer.

1. Wearing blue light protective glasses, such as Hello computer glasses from Germany, can effectively resist chronic light damage to the eyes caused by computer blue light.

2. Pay attention to rest, watch the computer for no more than an hour each time, rest your eyes for 10 minutes, and have regular rest and eye exercises.

3. Appropriate amount of lutein and multivitamins are supplemented to enhance the antioxidant function of the fundus.

Don't play for an hour, so that there is no harm to the eyes, you try not to play with the mobile phone at night, if you don't play, the eyes are easy to astigmatism, myopia is easy to do, astigmatism is very difficult.

You can turn down the brightness so that your eyes don't get tired easily, and you should pay attention to radiation protection. Generally, 3 computers are enough for an hour. When you play with your phone, you can look farther away to prevent eye fatigue and myopia, thank you.

- -You play for an hour or two in the afternoon, and the brightness is turned down = and the evening is equinox.

1. Avoid facing the computer continuously for a long time, pay attention to the rest in between, usually operate continuously for 1 hour, and rest for 5 to 10 minutes.

2. Adjust the distance of the phosphor screen. The recommended distance is 50-70 cm, and the phosphor screen should be slightly lower than the horizontal position of the eye 10-20 cm, with a downward viewing angle of 15-20 degrees. Because the angle and distance can reduce the need for refraction, the chance of eye fatigue is reduced.

3. Maintain good living habits, get enough sleep, and don't stay up late.

4. Look into the distance, let your eyes adjust and rest, and increase outdoor activities.

5. It can also be combined with moisturizing eye drops.

I've been looking at the computer for a long time.

Pay more attention to rest, get up and walk around for about 1 hour Walk around, look at green plants or in the distance, so that the eyes can be effectively relieved.

After about an hour in front of the computer, get up and move your waist and neck. Try looking into the distance to relieve eye strain. Apply some anti-fatigue eye drops in moderation. There are also long periods of time in front of the computer to eat more bananas

ps.You can also do eye exercises, hehe.
