Use This Windows Setting to Reduce Eye Strain

In today’s age, prolonged screen time on a computer is almost inevitable. However, it also causes fatigue and eye strain. Fortunately, Windows offers a built-in feature that can help alleviate this problem.

What is Night Light?

Night Light is a feature in Windows 10 and 11 designed to reduce the blue light emitted by your screen. Blue light, while beneficial during the day, can cause eye strain and disrupt the sleep cycle when exposed in the evening.

open Settingsclick on System in the left panel, and then click show in the right section. Under Brightness and color section, toggle Night light on or off. You can also click the panel to customize other options to suit your preferences.

You can schedule the Night Light by setting specific times for the Night Light to turn on and off automatically, such as sunset to sunrise. You can also control the intensity of the warm color, making it as subtle or strong as you want. Warmer colors are more effective at reducing eye strain, but you should experiment to see what feels most comfortable.

By configuring Night Light, you can significantly reduce the exposure of blue light from your screen, helping you minimize eye strain and improve your overall comfort during extended periods of screen use.

How Does the Night Light Work?

Higher color temperatures emit more blue light and appear cooler, like daylight. Lower color temperature emits less blue light and appears warmer, like candlelight. Night Light works by adjusting the color temperature of the screen to warmer tones, which are easier on the eyes and less likely to interfere with your sleep.

Night Light changes the color temperature of your screen towards the lower (red) end of the color spectrum, reducing the amount of blue light emitted and create a calmer and more comfortable viewing experience. Windows essentially applies a color filter that effectively “blocks” some of the blue light.

The operating system does this by manipulating the RGB (red, green, blue) values ​​of the pixels being displayed, decreasing the blue component while slightly increasing the red component to achieve the warmest color tone.

This feature is especially beneficial when you use your computer in the evening or at night. Warmer colors are easier on the eyes, especially in low light conditions. In addition, blue light can suppress the production of melatonin, a hormone that regulates sleep. Night Light helps minimize this disruption.

Night Light is a simple but effective feature in Windows that can significantly reduce eye strain, allows for better sleepand improve your overall viewing experience. Try it and see the benefits for yourself!
