Description
LightBulb is an innovative application designed to reduce eyestrain caused by prolonged exposure to computer screens, especially during late-night work sessions. By continuously adjusting gamma levels, LightBulb transitions the display color temperature from cool blue tones during the day to warm yellow hues at night. Its primary goal is to harmonize your screen’s color with your surrounding light sources, bright sunlight during the day and artificial lighting at night.
With minimal impact on system performance and a wide range of customization options, LightBulb helps ensure a more comfortable viewing experience while you work, allowing you to focus without discomfort.
