Why does playing computer games for a long time damage my eyesight?

When teenagers play computer games, although the distance between their eyes and the electronic screen is similar to the distance between their eyes and the book when reading, the computer screen is the only target of attention. They spend more time concentrating on the screen for long periods of time, and their eyes are more on the screen, unlike when they are reading a book, so the workload per unit time of playing computer games is much heavier than reading, writing, and watching TV. In other words, if you spend the same amount of time playing computer games, watching TV, and reading books, you are most likely to experience eye fatigue when playing computer games.

In addition, the decrease in the number of blinks when playing on the computer leads to changes in the structure and function of the surface of the eyeball, which can easily cause visual discomfort and accelerated eye fatigue when using the eyes at close range, and also increase the risk of dry eye syndrome.

In addition, playing computer games for long periods of time often takes away from outdoor activities and sleep time. Many people are reluctant to go out for the sake of playing games, and even play computer games until late at night. Eyes fixed on a computer screen for a long time, this is a behavior with a high load on the eyes, if the eyes are often in a state of high adjustment tension and do not relax, it is easy to cause myopia.

Eyes staring at a close-up electronic screen for a long time can easily cause eye fatigue.

You can try Chinese medicine, and it is recommended to check it out as soon as possible.

Playing video games can only destroy eyesight. Because the brightness of the computer screen and the mobile phone screen is too bright. Looking intently at a screen for long periods of time can hurt your eyes.

Health Care Methods:

First, the blink of an eye method.

Choose a quiet place, sit or stand, relax your whole body, clear your distracting thoughts, open your eyes, keep your head and neck still, and roll your eyes alone. Start by staring straight down, slowly turn to the left, then directly above the gaze, to the right, and finally back to directly below the gaze, making 9 clockwise turns.

Then turn your eyes from the bottom of the gaze to the right, to the top, to the left, back to the bottom, and so on, another 6 turns counterclockwise. Do this 4 times in total. With each turn, the eyeball should be pushed to the limit as much as possible.

This eye-turning method can exercise the eye muscles, making the eyes flexible and bright.

2. Eye breathing and concentration method.

Choose a place with fresh air, sit or stand, relax your whole body, look straight ahead, slowly inhale your breath, open your eyes wide, pause for a moment, and then exhale slowly, and slowly close your eyes, and do it 9 times in a row.

3. Eyeball compression.

With your eyes closed, gently press the eyeballs with the fingertips of your index, middle, and ring fingers, or you can rotate and rub gently. Do not last too long or rub too hard, stop after about 20 seconds.

Fourth, the forehead pressure method.

The three fingers of each hand rotate and rub from the forehead** to the left and right temples, and then press the temples vigorously, using the fingertips to apply force. In this way, the bottom of the eyes will feel comfortable. Repeat 3 to 5 times.

5. Press the glabellar method.

Place your thumb belly against the recess below the base of your eyebrows and gently press or rotate. Repeat 3 times. When looking into the distance, the eyes should be turned in the right, up, left, and down directions, and the head should not be shaken.

Proper play can be relaxing, but improving eyesight varies from person to person, really

Playing games can improve eyesight, as American studies have found that playing games has better eyesight than not playing games.

It will change over time, and it can change from change to.

Problem description: Why is it easy to get myopia after playing with the computer for a long time?

Analysis: Generally, the refresh rate of the computer monitor (CRT) is too low to cause eye fatigue, the default setting of the computer is often 60Hz, and only when the refresh rate reaches 85Hz or higher, the computer's display will not flicker. However, the LCD display does not have this problem because it displays a static picture.

In addition, even if it is an LCD monitor, staring at the computer screen for a long time will cause eye fatigue, and long-term eye fatigue will lead to myopia, so it is recommended to leave the screen every hour or so and rest for 5-10 minutes.

The main reasons:

1.Like the display screen of the display screen will produce "blue light", the backlight is LED light, blue light is the blue part of the light (the display of white light must have blue light), the wavelength of blue light is between 400nm-440nm is relatively high, and the light is more harmful to the human eye (many displays advertise low blue light, remove blue light).

2.Strobe, in the display dimming mode, there are DC dimming, PWM dimming, etc., the strobe bulb light source keeps flashing between light and out, and it is easier to get tired when looking at low-frequency PWM display glasses for a long time, so it hurts eyesight for a long time.

The above display itself is harmful to the eyes (the monitor still has a lot of attention, such as the corresponding time).

3.The human eye is a problem-prone organ and is sensitive to distance and time. (So there is a standard sitting position, reading a book, screen time, eye exercises, etc. to adjust the eyes).

Therefore, playing games is often 1-3 hours or more for a while, and staring at the monitor for a long time naturally hurts the eyes.

When playing games, the eyes are closer to the mobile phone screen or computer screen, and the screen in the game is more colorful, and it will be more engaged, resulting in the eyes being in a state of tension and no rest for a long time, so the damage to the eyes at this time will be greater than before.

Looking at the computer and mobile phone screen for a long time, the blue light of the screen and the poor posture of being too close to the screen can lead to vision loss, as well as changes in the focus of the eyes.

Because you've been looking at something with lights.

Because both mobile phones and computers emit radiation.

If you play a game for a long time, your eyes will stiffen when you look at the screen of your phone that is very close to you for a long time.

Now research shows that many people who play games or work on a computer often have dry eyes! Dry eye syndrome is a condition in which the loss of tears or the function of the tear glands decreases, resulting in the appearance of tiny scars on the surface of the eye. The results of the survey showed that 31 2 of the people who used computers regularly were diagnosed with dry eye syndrome, and the incidence of dry eye syndrome was as high as 44 per student returning to school during the holidays.

This may not seem like a serious illness, but if you don't pay attention to protecting your eyes, it will continue to be serious, so if you can really protect it! Moisturizing your eyes is the best way to prevent it. Pay attention to eye habits, take regular breaks, work (play) continuously in front of the computer screen should not be too long, take a break of 5 10 minutes every 1 hour, and try to relax your eyes when you are in the gap.

The eyes are looking inward and downward, so when resting, try to keep your eyes looking upwards to the left and upper right. You also need to move your neck and shoulder muscles.

If you really don't know how to maintain it, choose eye exercises, do it every hour, it's okay!

Can playing games cause myopia?

Playing games often will speed up the myopia of the eyes, because of the radiation and high level of the screen, if you need to play games often for your profession, it is recommended to bring some anti-blue light eyes for some protection.

It must hurt a lot, playing games requires the eyes to be highly focused on the screen, and after a long time, the eyes are dry, and myopia will gradually form.

That's for sure, playing games regularly and staring at the screen for long periods of time can lead to dry eyes and short-sightedness.

High, staring at the phone screen for a long time can cause a lot of damage to the eyes. May cause high myopia.

High, I'm just short-sighted in games, and now the power is a bit high, ah......Hey, let's play less games.

Of course, it hurts a lot, but some people are born with good eyes and are not easy to be short-sighted.

This must be harmful, if you stare at the computer or mobile phone for a long time, the power will decline.

It's not high at all, you just don't want us to play the game.
