The eye is the most important and vital organ in our body.We cant even imagine our lives bliend and without vision.
The smartphone is a device that we use on daily basis and we are in the regular contact of that screen of mobile.
The screen emits very large amount of blue rays and these blue rays are very harmful for our eyes.
So I will recommend to use the third party applications like Night mode and others that are available on play store which reduces the amount of blue light that is emitted.
The MI phones has built in facility called Read mode you can also use that.
Than you.
