It just manages to work with every website somehow. The comfort of your eyes. wow! All the screen time spent over a day adds up and this really is an eye-saver.. Email, Facebook, YouTube, Google.. all of these can't hurt my eyes no more!

Фантастика! Только жаль, что я так долго не находил это расширение.

so beautifull! *-*

Great add-on all around. Helps my eyes, and it looks natural.
