Discover LightBulb: Your Ultimate Solution for Reducing Eyestrain
In today’s fast-paced digital environment, prolonged exposure to computer screens, particularly during late-night hours, can lead to significant eyestrain.LightBulb emerges as an invaluable application designed to alleviate this discomfort. While it shares capabilities with the built-in “Night Light”feature found in Windows 10 and apps such as F.lux, LightBulb sets itself apart with its superior customization options and additional features. This innovative tool adeptly adjusts the screen’s gamma settings throughout the day, transitioning the color temperature from a stimulating cold blue during daylight to a soothing warm yellow by nightfall. The primary goal of LightBulb is to synchronize your display’s color with the natural light in your environment—bright sunlight during the day and the softer tones of artificial lighting after sunset.
