What effect does lying watching TV have on your eyes?

Many people have similar habits. After a hard day's work, they lie in bed and watch TV beautifully after dinner, or lie on the sofa. Actually, watching TV from this angle is not good for your eyes.

Next, let's talk about what effect lying down watching TV has on your eyes and what harm it does.

In fact, lying down watching TV is really bad for your eyes. When lying down and watching TV, the rectus and oblique muscles inside and outside the eyeball will be seriously tired after watching for a long time. Just think about it, because you are lying down, it is difficult for your eyes to keep a normal horizontal angle with the screen, so you need to adjust your posture and your head position, and then your eye position matches your eyes.

After a long time, it will cause spasm and contraction of extraocular muscles and ciliary muscles in the eyeball, astigmatism, conjunctival congestion, increased tears, high intraocular pressure, blurred vision and decreased vision.

If you look sideways, keeping this posture for a long time will also affect the muscle fatigue around the eyes, which is really not scary. If it is serious, if you don't realize it for a long time, maybe eye deviation will become a permanent phenomenon.

It may also be dry eye, because there is no reasonable rest when lying down and watching TV. If the indoor light is dark, it is easy to cause dry eye, such as dry eyes, burning sensation, local redness and so on.

Speaking of which, I think of my colleagues' children. My colleague's child is only in the fourth grade, and his eyes are nearsighted by more than 500 degrees. Colleagues are a little tangled every time they talk about this issue. After all, the child is still young. If myopia can't be controlled, it will have an impact on children in the future. For example, if you take an examination of military schools and pilots, your vision will be limited if you fail.

I asked him what caused it. Colleagues said that his children have a habit of coming home from school, that is, lying on the sofa eating snacks while watching cartoons. The meal is ready. Do your homework after dinner. Then there are all kinds of sighs ... so, bad work and rest habits really have a great influence on the eyes.

Now that we know these hazards, let's talk about how to watch TV correctly ~

First of all, watching TV to find an angle, whether leaning on the sofa, leaning on the bed, or simply lying down, is harmful to your eyes and body. This non-parallel angle will lead to uneven exertion of eye muscles and cervical discomfort. Therefore, when watching TV, everyone should pay attention to keeping the line of sight basically parallel to the screen. This angle is the most suitable.

Also, don't watch TV for too long. After reading 1 hour, rest 10 minute. If you don't want to miss the excitement, you can turn on the TV and listen to the sound, then look out the window, or roll your eyes and relax your eyes properly.

Secondly, it is the problem of changing channels frequently, which also hurts your eyes. The moment you change the channel is the most exciting time for your eyes. Therefore, it is best to close your eyes when changing channels, or blink your eyes a few times to stimulate lacrimal gland secretion to avoid eye fatigue.

Let's talk about the distance to watch TV. Usually, the distance between the TV and you should be determined by combining the light and location at home. But there is a basic principle that the distance of about 3 to 4 times the diagonal length of TV screen is the best. Otherwise, it may lead to eye problems such as myopia ~

Finally, talk about the lighting problem: some netizens said that it is good to watch TV and turn on the main light; Others say that they like to turn off all the lights, so that they can easily find pictures in the dark and save electricity. In fact, these two practices are not correct. The best way is to turn on a small lamp with low wattage and soft light indoors and use it to adjust the indoor background brightness. In this environment, the eyes will not be tired, and it is said that it can also reduce the consumption of various vitamins in the body ~
