I'm so scared! This thing you do every day hurts so much!

I often see this statement on the Internet: XX turned off the lights and stayed up late to play with his phone, and he couldn't see when he woke up the next day! So don't turn off the lights to play with your phone, you will go blind!!!

Many of my friends called it scary after seeing it, but they still thought it was “really nice” when they lay in bed with their phones at night.

Mobile phones are the biggest enemy that prevents us from sleeping. We must check our phones before going to bed, otherwise we are afraid of missing something important. Especially playing with mobile phones in bed before going to bed, we know there are many harms, but we just can't control it!

How much damage does hiding under the covers and looking at your phone do to your eyes?

First of all, playing with your phone with the lights off is likely to cause dry eyes .

All lights are turned off, and the phone screen becomes the only light source. In this case, the light from the phone screen will be particularly dazzling, which may lead to a decrease in tear secretion. In addition, under normal circumstances, we blink 15 to 20 times per minute. However, when we use our eyes intensively and concentrate highly, especially when using electronic products such as computers and mobile phones, we often unconsciously forget to blink, which can also cause dry eyes. Not to mention that staying up late to use your eyes can easily cause eye discomfort, which I believe everyone has experienced.

If you become a dry eye patient, not only will your eyes be prone to dryness, pain, photophobia, and tears in the wind, but in severe cases you may even need lifelong treatment, so you must pay close attention to it.

Secondly, it causes damage to eyesight.

This needs no explanation, everyone should understand it, especially for minors, the impact is even greater. If they play with mobile phones while lying on their side for a long time, it may also cause poor vision.

Finally, will you go blind if you turn off the lights and play with your phone?

It's possible, but not very likely.

For example, if someone already has glaucoma or has a family history of glaucoma , when they stare at their phone in the dark, the muscles in their eyes will become tense and produce a series of changes that will cause an increase in intraocular pressure. Over time, this may cause irreversible damage to the optic nerve.

There is also a saying that playing with a mobile phone in the dark may damage the macula. We know that the macula is the area with the sharpest vision in the human fundus. Once the macula is diseased, it will directly and seriously affect vision and may even cause blindness. But generally speaking, damage to the macula is related to the intensity of light, the duration of light exposure, and the type of light exposure. Will playing with a mobile phone in the dark damage the macula? There is no clear conclusion yet.

In general, don't play with your phone with the lights off!

What to do? Aier Doctor gives you these free suggestions:

Turn on the light when playing with your phone at night

After turning off the lights, the bright screen and the dark environment have too much contrast, which will irritate the eyes and cause eye fatigue. If you want to play, try to turn on the lights. After a day of use, the eyes are already tired enough. Otherwise, the harm index will increase by one level.

Lower the phone brightness

Most mobile phones have a night mode. Turn it on at night and try to adjust the light of the phone to a low level to reduce the brightness irritation to the eyes. It is best to adjust it to warm yellow light, which will cause much less irritation to the eyes.

The posture must be correct

Don't play with your phone while lying on your side, as this can easily cause a deviation in vision between the left and right eyes. Over time, your eyes will feel swollen and images will overlap for a short period of time. Don't play with your phone while lying on your stomach. The best way is to play with your phone while lying on your back, with the screen tilted downward by about 45 degrees. If your elbows are tired, you can use a blanket to pad them under your elbows. This is the method that has the least impact on your health.

Control time and distance

When using a mobile phone, keep your eyes 30cm to 50cm away from the phone. More importantly, limit the time you spend playing with your phone before going to bed. After all, sleep and health are much more important than mobile phones.

Blink more

When the content on the phone attracts us, the number of blinks will involuntarily decrease. Remind yourself to blink more. When your eyes feel tired or your vision is blurry, give your eyes a rest.

Notice:

If you want to ask, besides the above methods, what else can minimize the damage to the eyes? The best way is, of course, to play less or even not play with your phone before going to bed!

Finally, when your eyes feel uncomfortable, please go to an ophthalmologist in time to give the ophthalmologist a chance to demonstrate his or her abilities, and do not use medication blindly.
