Essential extension for my daily use. Not sure about the benefit to my eyes but websites look much nicer.

Been using this extension for some years on multiple web browsers. Some sites (or domains) can be troublesome, but this generally works really well, helping to alleviate eye strain.

One of the greatest addons!

I like this add-on very much, very well done and very effective. The adjustment setting options are superb, I have tried other extensions but they were either too dark or yellow this is a good fit for me.
