How can I use a smartphone to protect my eyesight?

A. 1

Due to the nature of LCD monitors, smartphones generate blue light.
So using the blue light blocking filter app is good for your eyesight.
Of course, it's best not to use a smartphone.

The best way is not to use a cell phone.
Cell phones have a lot of influence because they receive electromagnetic waves from a close distance

It is recommended to make the brightness of your smartphone as similar to the brightness of your surroundings as possible.
I usually use it at maximum brightness, but if I use it like this, my eyes get tired because of the strong light.
And if you use it outdoors, you can make your eyes more tired by reflecting sunlight, so you need to use it properly.
