Overview
Iris
Iris is a dedicated eye protection solution that helps you reduce the physical toll of long hours in front of a computer. By automatically adjusting your screen's color temperature and brightness, it eliminates the flicker and blue light that typically cause eye fatigue and disrupt your natural sleep cycles. You can choose from various pre-set modes like Health, Sleep, or Reading to match your current activity and environment.
The software works at the driver level to control the pulse-width modulation (PWM) of your monitor, ensuring a flicker-free experience even at lower brightness levels. Whether you are a programmer, designer, or office worker, you can customize every aspect of your display to protect your vision and maintain high productivity throughout the day without the typical afternoon burnout.
SunsetScreen
SunsetScreen is a lightweight Windows application designed to protect your eyes and improve your sleep quality by managing your monitor's blue light output. As evening approaches, the software shifts your screen's color temperature to warmer tones, mimicking the natural cycle of the sun. This process helps maintain your circadian rhythm, making it easier for you to wind down after working late at your computer.
You can take full control of your viewing experience by setting specific sunrise and sunset times or choosing from various color presets. The tool runs quietly in your system tray and consumes minimal resources, ensuring your PC stays fast while your eyes stay comfortable. It is a practical solution for office workers, gamers, and students who spend long hours behind a screen and want to avoid digital eye strain.
