Ayuda en un % a descanzar la vista, siempre que mantenga una tonalidad gris, pero es agradable.

This night mode and accessibility extension is great. Modify your websites so they look like YOU want them to look. Whether you want them dark, light or simply modified for increased contrast and greater usuability. Forget the rest, this is the best. Thank you Pavel!

It is truly wonderful to have Midnight Lizard over here at FF, now; my ultra-sensitive eyes thank you!

Midnight Lizard is not like the other night mode and accessibility extensions – it’s akin to magic
for those seeking a simple manner in which to achieve overall performance and theming perfection. I have tried them all, and what sets ML apart, from the others, embraces the combination of fast loading, beautifully rendered pages that anyone can quickly tweak – in tandem with the fact that it works flawlessly on nearly any site I visit. This extension comes pre-loaded with several one-click themes plus ML will remember your on-the-fly adjustments for the next time you visit the page. Finally, the readability is unmatched via this extension, boasting enhanced syntax, and even a blue filter. Midnight Lizard makes your web surfing an elegant experience, while it preserves your eyes!
