What is CF.lumen?

Your Android device's screen can be a significant source of eye strain and disrupted sleep patterns, especially when used in low-light conditions. CF.lumen offers a innovative solution to this problem by dynamically adjusting the color temperature of your display in response to the position of the sun With CF.lumen, your screen will automatically take on a warmer, more amber-toned appearance when the sun goes down. This reduced blue light emission helps to minimize the stimulating effects on your brain, allowing for a more natural and soothing viewing experience in the evenings. The result is less eye strain and a better sleep cycle, as your body is not being kept awake by the harsh, blue-heavy light often emitted by digital screens To use CF.lumen, you will need to have both Chainfire3D and Chainfire3D Pro installed on your Android device. Once set up, the app will seamlessly adjust your screen's color temperature throughout the day, without any manual intervention required. A "sleep mode" is also available, which bathes the entire screen in a deep red tone to preserve your night vision when needed If you encounter any issues with the automatic light sensor function, you can simply tap the app's notification in the status bar to temporarily disable the color adjustments. This allows you to enjoy normal screen colors for activities like gaming or photo viewing, before the app resumes its natural adjustments For a truly holistic approach to reducing digital eye strain, the developers also recommend installing similar software, such as f.lux, on your computer. By aligning the color temperature of all your screens, you can create a more consistent and comfortable viewing experience across devices
