Daytime: I swear to go to bed early tonight and never play with my phone again. Nighttime: Forget it... I won't play with it starting tomorrow!

If you also have the habit of playing with your phone before going to bed , please continue reading.

After insisting on playing with your phone before going to bed

Good mood, bad eyesight

01

May cause acute concomitant esotropia

Night owls who love to lie on their side and play with their phones , please pay attention. There was a hot search on Weibo some time ago↓

A female college student spent a long time lying on her side playing with her mobile phone. She went to the hospital for a check-up and was diagnosed with strabismus .

She plays with her mobile phone for an average of 10 hours a day, which has caused her vision to deteriorate and she can no longer distinguish between flat and three-dimensional objects.

Are you scared? Let's see how medicine explains it.

When we turn off the lights and lie on our side to play with our mobile phones, the distances at which our left and right eyes see the screen are different, which may cause vision deviations in the left and right eyes .

That is to say, not only will it make you nearsighted, but it may also cause one of your eyes to have lower degrees while the other has higher degrees .

Lying on your side for a long time playing with your phone and using your eyes at close range will cause your eyes to over-adjust.

When it cannot adjust, it may induce acute concomitant esotropia, commonly known as cross-eyes.

****Not only will it make you see double and feel dizzy, but most importantly, it will also affect your appearance.

If you are nearsighted and often use your eyes at high intensity and close range, you should be more careful.

02

May cause dry eyes

Many people like to lie in bed after turning off the lights, playing with their phones , watching TV, or browsing Taobao.

I went to sleep after watching this episode, but ended up watching three or four episodes by accident. When I looked at the time, it was 2:00 in the morning ...

You had fun, but your eyes were exhausted .

Generally speaking, we blink about once every 5 seconds, which allows tears to cover the surface of the eyeball and moisturize the eyes.

But when we turn off the lights and look at our phones at night, we blink less and the tears on the surface of our eyes begin to disappear.

Moreover, in dark environments, our pupils will dilate, and we will be more stimulated when looking at the light of the mobile phone screen.
When you wake up the next day, you may feel that your eyes are very tired. Not only are they dry , but there is a lot of eye mucus and they are also very dry .

If this continues for a long time, the stability of your tear film and the integrity of the corneal epithelium will be destroyed.

" Dry eyes " may come to you.

03

It may also cause glaucoma

Xiao Ming was originally a good young man with 5.0 vision, but due to long-term overtime work and heavy pressure, he stayed up late at night to retaliate and curled up in bed playing games on his mobile phone.

Gradually, my vision became blurry and I thought I was nearsighted. But when I went to the hospital for a check-up, I found out that I had glaucoma at such a young age.

"Oh, if only it had been discovered earlier... The doctor said that if it was discovered too late, the optic nerve would have been damaged."

Many people may not know that the inside of our eyeball is filled with a transparent liquid called "aqueous humor".

Under normal circumstances, it flows between the front and back of the eyeball, thereby exerting a certain pressure on the retina, which is medically known as intraocular pressure .

However, when you turn off the lights and play with your phone, in order to see clearly in the dark environment, your pupils will dilate for a long time and your irises will be squeezed.

If the outflow of aqueous humor is more or less obstructed, it will cause increased intraocular pressure .

This can easily compress the optic nerve in the long term, causing visual field loss and decreased vision, and glaucoma may even occur.

This is no joke. The damage to the optic nerve and visual function caused by glaucoma is irreversible and may even cause blindness .

All friends who like to turn off the lights and play with their phones should pay attention to this!

The correct way to play with your phone before going to bed

It is easier said than done not to play with your phone before going to bed.
Don’t worry. Even if you can’t spend less time on your phone, I still have a few other tips that I highly recommend.

1. Turn on the lights to ensure the brightness of the room, turn on a warm light at the head of the bed , and keep the distance between your eyes and the phone at least 30 cm.

****2. Dim the phone brightness**** It is best to dim it to a soft and non-glaring tone . Set the font size to an appropriate size and the background color to be non-glaring.

3. Try not to lie on your side or prone. Place a supportive pillow at the head of the bed , sit upright as much as possible, and do not lie on your side or prone while browsing your phone.

If you can't do all of the above, then stay away from your phone and go to bed early. (You are not allowed to not listen)
