Night Eye enables dark mode on any website using a new algorithm that analyses and converts all colors instead of simply inverting them. When Dark Mode is enabled, the colors of each website are analyzed and converted in a such way to provide you with a smooth and consistent dark theme.

Dark mode is better than the blinding bright design on most websites in 3 aspects. Negative long-term effects by the increasing screentime can be mitigated by inverting the colors in the darker spectrum. This is especially valid if you are suffering from various eye conditions such as photophobia or working in low-light environment. There are also studies suggesting that ambient lights affect circadian rhythm and sleep cycles. Last but not least improved productivity is observed mainly due to the decrased strain on the eyes.

Night Eye enables night mode (dark mode) on all your favorite websites like Facebook, Quora, Github, Stackoverflow, Wikipedia and much more. It does not work on "chrome://" urls or local files "file://" (no extension does, by the way - limitation of the browser).



The extension allows you to quickly switch the three available modes:
- Dark - Go into complete dark mode. All colors, small images and icons will be converted to give you the smoothest dark experience possible.
- Filtered - The websites’ colors will not be changed, but you can still adjust brightness, contrast, warmth and more.
- Normal - Dark themes are not always better for eye strain, so you can choose normal mode for the website.


- OS/Browser Color scheme integration - sync Night Eye with your macOS/Windows dark themes.
- Deep integration with websites that have their own built-in dark themes.
- Schedule dark mode to turn on and off
- Custom dark mode for online PDFs
- Export/Import data between your browsers

Any modifications you make such as contrast level adjustment, blue light filter and etc. can be applied to a single website or globally.

- Images - Night Eye analyses and converts only the small images and icons in a website to give you even smoother experience. Facebook posts and other significant media are not converted.
- Brightness / Saturation / Contrast - Adjust the brightness, the contrast and the saturation to match the recommended healthy levels and protect your eyes. The default setting for each is 50%, but you can customize each to the preferred levels.
- Blue Light - Take care of your eyes by eliminating the blue light coming from your screen. Highly recommended especially during late night browsing. Simply slide to the preferred level of warmth.
- Dim - Extremely useful if you are working in a dark space/room and the screen is the only source of light in the room. The default setting is set to 50%, but you can customize it as you please.


Built-in support system - we take pride in being available to provide reliable support and help you with any problems or issues you might experience with the extension. (Support is in English only for now.)


We only store the saved settings for each visited website of each Night Eye user in their localStorage (your computer). This relates to all adjustments made by the user to improve their browsing experience through the use of Night Eye


Night Eye comes with to options: Night Eye Lite and Night Eye Pro

Before going to Lite, we would like to invite you to try out Night Eye Pro for free for 3 months - no credit card, no payment asked - simply install and try it out.

Solid Dark Mode For Safari

This works pretty well on most websites. I enjoy the the dark mode for pdfs, which I often cannot find for other extensions. I wish there were cheaper options though and no subscription models.

Developer Response ,

Thank you for the review. Why we use subscription model - the internet is evolving and to keep up with new standards we must actively develop the extension. Every once in a while in the year we have discounts so follow us on social media to be ready.

Night Eye Is The Best!

Over the past several months I purchased and tried many dark mode extensions for my iPhone, but none of them really worked correctly. I then found Night Eye and it is the best. When I first downloaded the app you offered me a very generous 3 month trial with all features, wow how nice is that. I guess if you have a great product like Night Eye you don’t mind letting people see how great it really is. I don’t like app subscriptions and you also offered me the option to purchase a one time license that does not expire, very nice. After using Night Eye for about an hour I was so impressed with the performance that I purchased the one time license. I now have a dark mode app that works great on every hard to display web site I have tested it with. My thanks to the developers for an easy to use product that works great at a reasonable cost. Job well done!
