Are computers bad for your eyes? If so, how to prevent it.

The popularity of computers and the Internet has undoubtedly brought great changes to people's lives, but browsing or reading articles on computers for a long time is harmful to people's eyes. But experts say there are some very simple tips that can help computer users minimize this damage — as simple as blinking an eye or looking away.

Dr. Donald Schwartz, an ophthalmologist at the American Academy of Ophthalmology in Long Beach, California, said looking at a computer screen does not cause serious eye disease. But prolonged staring at a screen by office workers can cause what ophthalmologists call "computer vision syndrome." Schwartz explained

Computer vision syndrome is caused by the eyes staring at a screen for too long at a very close distance, and the eyes do not get rest. He said eye diseases associated with computer use were more common among patients who practiced them. ”

Other factors that can affect eye health include screens that are too dazzling or reflective in low light, as well as dry eyes due to infrequent blinking, which can lead to eye pain. But Schwartz said there are several things that might help computer users. One suggestion, he says, is to blink your eyes a few more times and "let the lubricating tears moisten the surface of your eyes."

For those who wear multifocal lenses, they are at greater risk of eye fatigue if their lenses are not "in sync" with the computer screen. "It's very important that people sit in front of a computer with enough area to see clearly through the multifocal lenses and make sure that distance is appropriate," Schwartz said.

He said that everyone has to give their eyes a break from time to time while staring at a computer screen, "Take a break every 1 hour or so so so that your eyes can get a proper rest and you can look into the distance." The American Academy of Ophthalmology also made the following recommendations:

1.Choose a computer monitor that can be tilted or rotated and has contrast and brightness adjustments.

2.With an adjustable computer chair.

3.Place the reference materials you want on the file holder next to your computer, so you don't have to turn your neck and head back and forth, and your eyes don't have to adjust the focus as often.

Schwartz emphasized that long-term computer use is not linked to serious eye injuries. "These claims are not true in terms of the damage to the eyes caused by computer screens or any particular eye disease caused by the use of the eyes," he said. ”

Sitting in front of a computer for too long is harmful to your body and eyes. But it's understandable that I have to stay in front of my computer in order to work!

After you've been sitting in front of your computer for an hour or two, you get up and walk around, looking into the distance or at the greenery, and yes, you have to sit in the right position. Wear flat glasses for your eyes. That should be much better.

Harmful. You first go buy a protective screen and press it. Then buy a pot of greenery.

Buy a cactus and put it next to your computer!

1. All long-term operation of the computer will focus on the screen, resulting in a reduction in blink of sight, a decrease in the amount of tears, a slowdown in tear circulation, and an acceleration of tear evaporation, which is prone to uncomfortable symptoms such as eye astringency, dry eyes, and eye fatigue, and even not only keratitis, but also because the computer radiation (computer monitor and TV screen radiation value of 100 mg and 45 mg respectively) is absorbed by the lens, which can inactivate the lens thihydrogenase and lose glutathione reductase, resulting in the destruction of the lens fiber differentiation processAs a result, vacuolar cells appear, and the vacuolar cells move to the posterior capsule of the lens, concentrated in the posterior pole with the lowest resistance, and the lens is clouded due to the gradual accumulation of vacuolar cells, that is, the formation of radiogenic cataracts. If you can't supplement vitamins and other nutrients related to rhodopsin synthesis, it will lead to decreased vision, eye pain, photophobia, and dark adaptability.

Computer radiation is one thing, the key is not that the computer is harmful to the eyes, but the average person has no time to play the computer at the beginning, and the eyes have been in a state of seeing in front of the computer for a long time, causing visual fatigue and slowly producing myopia. It can even lead to more serious conditions. Not only computers, but also televisions, aren't they?

And if you read a book a lot, aren't your eyes good? Doesn't playing and playing games on the Internet with a mobile phone also hurt your glasses? So if you use a computer as a tool, it will be beneficial, and if you don't treat it as a toy, it will be counterproductive.

Either way, it's going to be harmful.

It's just that it can be lowered.

It is better to play for 2 hours and then spend 10 minutes outside, look at objects in the distance, and give your eyes a rest.

Now that science and technology are becoming more and more developed, society is becoming more and more progressive, and computers have basically been popularized in every family, but if you often have to look at the computer, it is easy to be bad for your eyes. Nowadays, some students may use the computer more in their studies, and some office workers should learn to protect their eyes when they have to face the computer every day. Protect your eyes, too!

1. Why do you have eye strain?

2. How to protect my eyes?

We are now in contact with the computer for more and more time, people's eyes will be easy to fatigue, because when we usually use the computer, there is actually a lot of radiation, which is very harmful to our eyes, so at this time, we should learn to protect our eyes. When using a computer, you should first learn some basic functions of the computer, and you should first adjust some of the brightness of the computer monitor, which should be adjusted to the power that suits your eyes. If the brightness is very dark, it will easily cause eye fatigue, if the brightness is too high, it will have a greater radiation effect on the eyes, hurting the eyes, and the number of words on the computer display screen should also be appropriate, and the font should be clear.

3. Broccoli, spinach, carrots.

People may like to eat broccoli in summer, because broccoli is a very good food for women, broccoli contains a lot of vitamins and dietary fiber, these good nutrients for the body can help anti-aging, maintain the elasticity, and this kind of substances are actually very helpful to the eyes, some of the nutrients contained in these can protect the cells of the eyes and reduce the impact of other factors on the eyes, spinach, It has the effect of replenishing blood to people's bodies, but in fact, it also has a role, that is, it is particularly good for eyesight. Carrots are very rich in vitamin A, and vitamin A can protect people's eyes and relieve eye fatigue.

For long-term computer workers, the best way to protect their eyes is to intermittently let their eyes rest, look into the distance, see some green things, and also do eye exercises; Keep the distance between looking at the computer, don't use your eyes for a long time, pay more attention to rest, and avoid staying up late; The brightness of the indoor lights should not be too high or too dark. Eat more foods containing lutein, such as corn, spinach, cabbage, broccoli, egg yolk, pumpkin, carrots, etc., which have the effect of protecting eyesight.
