🌅 What is f.lux and why do you need it?
Have you noticed that after many hours at the computer you feel:
- Eye fatigue and pain
- Difficulty sleeping at night
- Headache from bright light
All this happens because of blue light that your screen emits. This light is useful during the day because it keeps us awake, but at night it "confuses" our brain and makes it think it's still daytime!
✨ What does f.lux do for you?
The program automatically changes the colors of the screen. In the morning and at noon the screen is bright, while in the afternoon and evening it becomes warmer and softer.
After you tell it your city, f.lux knows when the sun rises and sets and adjusts accordingly.
- Film mode: For a better experience when watching movies
- Night work: For those who work late
- Dark room: For ultimate protection from blue light
