Mobile phones have long been an integral part of life.

If you can't use your cell phone for 24 hours, it is estimated that many people will crash.

Xiaobian also likes this. The first thing to get up every day and the last thing before going to bed is no doubt about mobile phones.

However, in fact, this habit will do some harm to the body.

If you can't change it at one thirty,

Well, at least, you should know the following points:

1 don't play your cell phone sideways.

Not only is it lying on the phone, many people still like it.

。

And sideways mobile phone will cause greater damage to the eyes. For a long time, the eyes will be short of blood supply and swollen.

2 brightness of mobile phone should be lowered a little.

Many people curl up at night.

At this time, the brightness of the mobile phone should be lowered a bit. Strong light is harmful to the eyes, and the cell phone tilts to the eyes as far as possible, so that the eyes will not feel too tired for a long time.

3 night screen as far as possible to night mode.

We perceive fonts to be identified by chromatic aberration. The bigger the color difference of the two colors is, the more eyesight is spent. The color is white, orange, yellow, green, blue, and purple, and other derived colors are covered in it.

So I know why the night mode is always black plus purple (or grey).

In the evening, you should use cool colors instead of warm colors. That's why many browsers have built-in nighttime mode. The color of the night mode is too cold to protect your eyesight.
