Protect Your Eyes on PC: Everyone Needs This Tool in Dark Season

While natural sunlight loses blue tones during the day and becomes reddish, regular LCD screens constantly tend to have a bluish tint. This can disrupt the hormone melatonin, which is responsible for the human sleep rhythm. The higher the blue component of the light, the more the hormone is affected. This can interfere with falling asleep, as researchers have shown in some studies.

Windows night mode solves this problem in a very simple way: If you activate the option, the color temperature is adjusted to the time of day and in the evening, as soon as the sun has set, a twilight is simulated . It doesn’t look pretty, but it should actually ensure better and healthier sleep.

But Windows’ new onboard tool isn’t the only way to adjust your own display for the evening hours. In addition to the freeware f.lux, which is also available for macOS, you can also achieve a similar effect with the open source program LightBulb.
