How to Use Night Light to Reduce Eye Strain
In this day and age, using a computer screen for long periods of time is almost unavoidable. However, it can also cause eye strain and fatigue. Fortunately, Windows has 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 from screens. Blue light, while beneficial during the day, can cause eye strain and disrupt your sleep cycle when exposed in the evening.
Open Settings , click System on the left panel, then click Display on the right panel. Under Brightness & color , turn Night Light on or off . You can also click the control panel to customize more options to suit your preferences.
You can schedule Night Light by setting specific times for Night Light to turn on and off automatically, such as from dusk to dawn. You can also control the intensity of the warm color, making it as subtle or as strong as you like. Warm 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 amount of blue light from your display, helping to reduce eye strain and improve overall comfort during long periods of screen use.
How does Night Light work?
Higher color temperatures emit more blue light and look cooler, like daylight. Lower color temperatures emit less blue light and look warmer, like candlelight. Night Light works by adjusting the color temperature of your screen to warmer tones, which are easier on your eyes and less likely to affect your sleep.
Night Light shifts the color temperature of your display toward the lower (red) end of the color spectrum, reducing the amount of blue light emitted and creating a more comfortable, soothing viewing experience. Essentially, Windows 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 - reducing the blue component while slightly increasing the red component to achieve a warmer tone.
This feature is especially beneficial when using your computer in the evening or at night. Warmer colors are easier on the eyes, especially in low light conditions. Additionally, blue light can suppress the production of melatonin, a hormone that regulates sleep. Night Light helps minimize this disruption.
Note : Night Light does not completely eliminate blue light. It simply reduces the intensity of the light to a level that is more comfortable for your eyes, especially in the evening.
Night Light is a simple yet effective feature in Windows that can significantly reduce eye strain, help you sleep better, and improve your overall viewing experience. Try it out and see for yourself the benefits it brings!
