It's been 2 years I use the application "f.lux" in order to soften the light of my screen.
With this application you can make the light of the screen more warm an this is really relaxing for eyes!
This is an image to compare a screen with an without f.lux :
This application is available on phones and on computers.
If you want to try I give you the link of the app, it's totally free : http://www.01net.com/telecharger/windows/Personnaliser/Ecran_de_veille/Utilitaires/fiches/47902.html
I don't receive money for this pub, it's just it's a really useful app and I want to share it with you :p
