What is the maximum amount of time a day can a myopic eye play with a computer?

1. The brightness of the screen (computer or TV) must be soft, with a certain contrast but not too strong, otherwise it will cause eye fatigue.

2. After staring for a long time, take your eyes off for 10 to 15 minutes.

3. Soak medicinal eyelet or chamomile flowers in water (available at pharmacies), leave the water at a suitable temperature, then soak a towel and apply it to the eye area for 10 to 15 minutes.

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.

This is very damaging to the eyes, so it is recommended to take two or three hours a day and take a 10-minute break every 50 minutes, which is good for protecting the eyes.

Because there are many factors that cause myopia, there are several factors that may cause myopia:

1. Eye habits

1. Excessive single eye use.

Looking at the mobile phone and computer for a long time not only affects the health of the body, but also makes the eyes overburdened, the muscles inside and outside the eyes are in a tense state for a long time and can not get rest, over time, when looking at the distance, the muscles of the eyes can not relax and are in a spasmodic state, so that the distance will feel blurred, thus forming myopia.

2. The distance between the eyes is too close.

Many people look at mobile phones or books very closely, and the closer they look, the heavier the fatigue in their eyes. Too close a distance can also make the adjustment of the eye abnormally tense, which can cause accommodative myopia, also known as pseudomyopia.

If the eyes are not relaxed in time, the ciliary muscles will not be able to expand and contract flexibly, or the adjustment will be excessive, causing excessive pressure on the eyeball from the extraocular muscles, and the intraocular pressure will increase, resulting in the lengthening of the anterior and posterior axial axes of the eyeball, forming axial myopia (true myopia).

Lighting that is too strong or too weak when looking at something, reading a book while driving or walking, or reading while lying down can also cause the same damage to the eyes.

2. Genetic factors

Myopia has a certain genetic predisposition, especially high myopia (above 600°), which is much more obvious than general myopia.

In patients with genetic factors, the incidence of myopia is early, and myopia often begins before entering puberty, and most of them are above 600 degrees. This type of high myopia is medically called degenerative myopia. High myopia is usually a recessive chromosome, i.e. both parents are highly myopic and 100% of the next generation is highly myopia.

One parent is highly myopic, and 50% of the children are highly myopic, but there are also manifestations of incompleteness.

3. Nutritional supplementation

To protect your eyes, daily nutrient intake is also important.

Vitamin A in animal foods and carotene in plant foods are directly involved in the formation of rhodopsin——— which are chemicals that absorb light on the retina, and are substances that protect the eyes and maintain normal vision.

Fourth, the comprehensive ability of the eyes

Our eyes are not only the ability to see, that is, the ability to see, but also the ability to see, synchronous, fusion, stereoscopic vision, adjustment, gathering, following, saccade, and so on. These abilities will affect the level of our power.

This is not necessarily, it depends on the constitution and age, and it is generally about 15 days, and the vision will be blurry.

In addition to eating and sleeping every day, looking at mobile phones and computers for 17 hours, if you turn off the lights and lie down, you will be myopic for about a month or two. However, after myopia, it is no longer possible to return to normal vision.

In addition to eating, sleeping and looking at mobile phones and computers for 17 hours a day, it is easy to become myopia, and it is possible to become myopic in a month or two.

In addition to eating, sleeping, and watching for 17 hours a day, how long will it take for mobile phones and computers to be mentally like yours, and you will be short-sighted in less than a month. And they are prone to eye problems.

Every day, in addition to eating, sleeping, looking at the mobile phone for 17 hours a day, in addition to eating, sleeping, looking at the mobile phone and computer for 17 hours. How long does it take to become nearsighted? I don't think I'll be nearsighted in less than three months.

In addition to eating and sleeping every day, how long does it take to go back to the dormitory after watching the mobile phone and computer for 17 hours, I think if you have to use your eyes like this every day, I think it won't take you a few days for your eyes to become myopic again.

In addition to eating, sleeping, and looking at mobile phones for 17 hours a day, how long does it take for the computer to become myopia? Soon I will be short-sighted for about half a year.

It also depends on how you look at it.

If you are very focused, you will stare closely and do not pay attention to adjusting your eyeballs in the middle. Well, it's easy to become short-sighted. If you pay attention to eye hygiene during this 17-hour period, often look far away, don't focus too hard, stay away, and rest for a while.

In this way, you will not become short-sighted.

Thank you for your question.

In addition to eating and sleeping, how long does it take to eat after watching a mobile phone and computer for 17 hours? If you look at your mobile phone and computer every day in addition to eating, then it means that your lifestyle has a very big impact on your health, so it won't take long to cause well, ban, and other physical conditions.

Within a month, I will be myopia, because I eat and play with my mobile phone every day, and I don't see the green plants and the scenery outside, and my vision is tired and myopia.

Looking at mobile phones and computers for 17 hours a day is very harmful to the eyes. You should look at your phone and computer sparingly. You should participate in more sports, which is good for your health. If you look at your mobile phone or computer for a long time, your eyes will be in a state of fatigue and you will soon become myopia.

In addition to eating and sleeping every day, looking at my mobile phone for 17 hours, I think it will become myopic in less than a month.

It's hard to say, but if you keep your eyes at high intensity every day, you will definitely be short-sighted.

Vary. I believe it won't be long before I look at electronic products, and no matter how good my eyes are, I will have myopia or other problems.

Looking at the computer for a long time can damage your eyesight, and your eyes hurt. Looking at the mobile phone for 17 hours a day, the computer time is a bit long! You can find something else to do.

17 hours of looking at the computer, not only will make you short-sighted, but also make you blind, you should rest every day for more than 40 minutes with your eyes, you say that you can not be blind when you open the computer for 17 hours in a row?

This is not necessarily, it depends on the condition of your eyes, but it will definitely not take too long to become myopia.

Hello, this is different according to each person's physique, how long myopia time is different, but it should be quite fast on the whole.

When you do this, it's not only bad for your eyes, it's also bad for your body.

Myopia can develop in a month.

Hello, on this issue, it's hard to say, look at people.

Playing with mobile phones often or looking at the computer often, as well as using your eyes excessively, may lead to myopia, and it is also an important factor in the appearance of myopia.

Under normal circumstances, if we stare at the computer for 8 hours a day without doing other actions, then our eyes will easily be caused by myopia, but if we can reasonably protect our eyes through some methods, then even if we look at 8 hours or more a day, it will not cause myopia, so reasonable methods to protect our vision are very important. If we don't pay attention to protecting our eyesight, then our eyesight will decline very quickly, but if we consciously protect our eyesight in our daily life, our eyesight will always be very good, many people until they enter old age, the eyesight is also very good, this is due to the result of their reasonable protection of their eyesight when they are young, so we must pay attention to the way to protect eyesight, then in daily life, if we often stare at the computer, There are several ways to protect your eyesight:

1. Don't use your eyes continuously

First of all, we should pay attention to the first point is not to continue to use our eyes, under normal circumstances, we should let our eyes relax for 5 10 minutes every 40 minutes of work, to an hour, this scientific method can make us better protect their eyesight, especially for those white-collar workers who stare at the computer all day, this method is very suitable for them.

2. Massage your eyes often

In addition, we can also protect our eyesight by massaging our eyes frequently, and the method of massage is also very simple, that is, eye exercises, I believe that everyone is very familiar with the elderly aerobics, because when we were 9 years of compulsory education, we had to do it 1 or 2 times a day, although we have not done it for a long time now, but I believe that everyone has not forgotten the practice.

3. Eat more eye-friendly foods

Finally, in our daily life, we can also protect our eyesight by eating more foods that protect our eyes, common eye-protecting foods in daily life, such as animal liver, carrots, deep-sea cod liver oil, etc., these foods can protect our eyes well, I recommend that you should eat at least 1 or 2 times a week.

Some people have different constitutions, even if they spend half of their time on the computer 24 hours a day, they will not be short-sighted. But 365 days a year, staring at the computer every day will definitely be short-sighted. Therefore, say the word "degree" in everything, arrange time reasonably, work carefully when working, and turn your eyes to other places immediately after the work is completed to move your eyes to prevent myopia.

Generally, it is myopia, and it can be said that it is very likely. Eyes are the windows to the soul, and we should all take good care of our eyes and spend less time online.

Of course, you will be short-sighted, after all, computers are very bright. We shouldn't spend more than 5 hours looking at the computer, which is particularly bad for the eyeballs and relatively dangerous.

It will cause myopia, because the eyes will feel tired for a long time, and the eyes have been receiving radiation when looking at the computer, which is very hurtful.

Watching the computer for more than 8 hours a day will definitely cause myopia, and there will be eye and eye fatigue, which is very harmful to the eyes, so we must usually control the time spent on the Internet.

You should take a break for about 40 minutes.

Study in an appropriate light environment, avoid direct or strong light when reading, do not get too close to the book, the correct reading distance is equal to the distance from the thumb to the elbow is about 30cm, sit at least 40cm away from the screen, when watching TV, at least 3 meters awayWhen reading, writing, watching TV, or playing computer games, remember to let your eyes have enough time to rest, every 45 minutes, please look into the distance for 5 minutes.

Getting involved in sports and outdoor activities can also be good for your eyesight.

It is recommended that you play less, this is not that playing with computers will increase myopia.

Yes, but you should sit in good posture and keep your distance.

No, just pay attention to protection.

Yes, it will aggravate myopia, take a break and do eye exercises. But it's better to play less, because playing too much of the game will affect intelligence and memory.

1. The time of close eye use should not be too long, every 40-50 minutes, you should take a little rest for 3-5 minutes, and look into the distance to relieve visual fatigue.

2. Read and write, play with the computer, maintain a correct posture, the height of the table and chair should be appropriate, and the distance between the eyes and the reading materials should be about 33 cm.

3. Mix whole grains, meat and vegetables, eat more vegetables and fruits, and don't eat partially. Lack of vitamins in food is prone to night blindness and dry eye disease, and lack of trace elements chromium and calcium in food makes it easy to suffer from myopia.

Fourth, when the brother Wu pure reading and writing, the light should be moderate, not too strong or too dark, and the light should come from the left front, so as not to hinder the vision of the hand. The light should be soft, if it is incandescent, it should be between 25 and 40W, and it is not recommended to read in the sun. Because the intensity of light has a direct impact on pupil dilation, too strong light will increase the intensity of eye accommodation, aggravate the intensity of eye labor, and it is easy to cause myopia after a long time.

Generally, desktop lamps should be less than 40 watts.

5. Avoid reading while walking or reading in a walking car. Because the carriage is shaking, the body is shaking, and the distance between the eyes and the book cannot be fixed, the burden on the glasses will increase. Often, this is likely to lead to myopia.

6. Actively participate in physical exercise to enhance physical fitness. As the eyeball follows the target, the ciliary muscles continue to relax and contract, and the synergistic effect of the extraocular muscles can increase the blood perfusion of the eye, promote the metabolism of the eye, and thus reduce eye fatigue. Moreover, the quality of physical fitness is also closely related to the occurrence of myopia in children.

Malnourished and weak children are prone to myopia.

7. Insist on doing proper eye exercises. By massaging the acupuncture points around the eyes to enhance the blood circulation of the eye socket, improve neuronutrition, eliminate the excessive congestion in the eye, and achieve the purpose of relieving eye fatigue, it is conducive to the prevention and treatment of pseudomyopia in adolescents, and is a good way for adolescents to self-care their eyes.

8. Eat less candy and envy high-sugar foods. Too much sugar will produce a large amount of acidic substances in the blood, and the acid will combine with the salt in the body, especially calcium, resulting in a decrease in blood calcium, which will affect the toughness of the eye wall, make the eye axis easy to elongate, and promote the occurrence and development of myopia.

9. Regularly go to the eye hospital to check the eyesight, and if it is found, it should be corrected in time to prevent the progression of myopia.

10. Eat less sweets. Because sugar needs a lot of vitamin B1 to metabolize in the body, if you consume too much sugar, vitamin B1 will appear insufficient. Vitamin B1 deficiency can affect the growth and development of the optic nerve, leading to vision loss.

Excessive intake of sugar will also reduce the calcium in the body, weaken the elasticity of the eyeball, and promote the development of myopia.
