Night Screen / Blackbulb: Adjusts Color Temperature for Reduced Eye Strains

Free open source software adjusts screen color temperature to filter out blue light, reducing eye strain and promoting comfortable viewing.

What is Night Screen / Blackbulb?

Night Screen / Blackbulb is a free and open source software application that adjusts the color temperature of your computer screen to make it appear more warm and reduce eye strain. It works by adding a reddish/orange tint to your screen to filter out harsh blue light that can disrupt circadian rhythms and make it difficult to sleep.

The software provides options to customize the color temperature, create schedules to automatically enable the filter at certain times (like at night), and whitelist apps to exclude from the tint. Users can lessen eyestrain when working at night, while still maintaining color accuracy for photo/video editing during the day.

As an open source program, Night Screen is transparent, customizable, and respects user privacy. With a small footprint, it can run smoothly in the background without draining system resources. Backed by a community of developers, the software is constantly maintained and improved.

Overall, Night Screen is an excellent option for Windows users looking to improve sleep quality and reduce eyestrain without sacrificing functionality. Its open source nature, transparency, and customization options help set it apart from many commercial blue light filter apps.
