What exactly is the damage of a computer to the eyes?

More than 80% of computer workers experience eye strain: 50% have dry eyes; Thirty percent of the symptoms are decreased vision, increased eye discharge, photophobia and dimmed vision. Computer software can work for a long time, but your excessive free radicals will cause damage to eye tissues, including cataracts and other eye diseases, and in severe cases, it will also cause eye blindness, but free radicals are produced too much or cleared too slowly, it will cause the body by attacking life macromolecular substances and various cells

It has been shown that the cause and development of cataracts are related to the damage of the retina by free radicals, leading to the destruction of the lens tissue. .

Problem description: How much does it hurt my eyes to hit the computer?

Dad said that my LCD computer has zero radiation to the eyes. But my grandmother still wouldn't let me play the computer, I couldn't figure it out.

Maybe it's an academic problem!

Then ask, how much damage does hitting the computer do to the eyes?

Analysis: The electromagnetic waves, ultraviolet rays, radiation, dazzling colors and infrared rays of the computer phosphor screen will also cause eye dryness, fatigue, double vision, blurred vision and even head and neck pain. Even eye diseases occur, mainly manifested as burning, photophobia, diplopia, itching, foreign body sensation, decreased vision, lens cloudiness, etc., some are accompanied by dizziness, headache and other symptoms, and may also induce some other eye diseases, such as glaucoma.

There is a misconception that using a liquid crystal monitor or a radiation screen can protect your eyesight. In fact, as long as you use the computer for a long time, your vision will definitely deteriorate 100% over time if you don't have the right protection for your eyes. Of course, you won't notice until you're about to wear glasses.

The ophthalmology department of a hospital in Beijing has done such an experiment: (100 people with normal vision).

There were 50 people in group A who used the computer for 2 hours and then performed vision and vision activities or visual health exercises that were 5 meters away, and 50 people in group B did not relax their vision after using the computer for 2 hours continuously.

After the experiment, the same results were: the average visual acuity of group A and group B decreased by 0 2, and the diopter decreased by 0 25 days on average.

The results were as follows: group A eyes quickly returned to normal vision after resting, while group B eyes did not return to emmetropia because they could not get effective rest after continuous computer use.

Conclusion: In fact, the way to protect your eyes is very simple, that is, you should pay attention to "rest your eyes regularly". However, we tend to sit in front of a computer for hours at a time, without even blinking an eye.

In the long run, your eyesight will definitely deteriorate! It would be nice if someone could remind us to take a regular break from our eyes.

The main harms are as follows:

1. The eye muscles are in a state of tension adjustment, and being in this state for a long time will make the eyes very tired.

2. Most people will be very focused when surfing the Internet, and the blink of an eye will be reduced, resulting in dry eyes.

3. The radiation of the computer will cause some damage to the eyes.

I am also a person who needs to use the computer for a long time, in fact, sitting in front of the computer all the time, not only has a good eye impact, but also has a more serious injury to the cervical spine and lumbar spine. Because I know more about the maintenance of my eyes, it will not cause any obvious damage, but the lumbar spine is often sore now, so please take me as a lesson and pay attention to maintenance.
