This feature is incorporated into Windows 10 and may be activated and deactivated at will. Reducing the amount of blue light emitted by your screen will help you get a better night's sleep and prevent eye fatigue. Windows 10 has a "Night Light" option for this purpose. Windows displays warmer colors at night when the blue light filtering option is activated. This guide will tell you how to enable the blue light filter in Windows 10 and get better sleep.

Why You Need to Turn on Blue Light on Your Device

According to studies, the blue light released by the displays of your electronic devices might be harmful to your health since it inhibits the production of the hormone melatonin, which is responsible for promoting sleep. As melatonin, the sleep-inducing hormone is suppressed by blue light at night, interrupts sleep, and increases wakefulness.

When exposed to blue light, your mood and memory are improved, making you more productive throughout the day. The lack of the sun's blue light at night (after sunset) allows the body to produce melatonin, promoting sleep. Modern technology exposes people to blue light at night because of the widespread use of fluorescent lighting and mobile devices like smartphones and tablets. This is bad for your health. According to research, blue light has been helpful throughout the day. Computer displays now come pre-programmed with a "Low blue light" mode.

Step 1

On the Start menu, click on it (or tap the Windows key from your keyboard). Enter "Night Light" in the search bar to get the setting. Alternatives include using the Night light option under Color in the Start >'' Settings >'' Display menu. Toggle the Night Light on/off option on the Display settings page if you choose this.

Step 2

To begin using the blue-light filtering feature immediately, click the Turn on now option in the toolbar. The intensity slider may increase or decrease Windows 10's blue light filter. Is this your first time using a blue-light filter? You may experiment with the intensity slider before turning on Night Light to see how your screen will appear at different intensities—like it's trying before you buy.

You may also use the grey Schedule night light toggle to limit the blue-light filtering to particular times. Specify how long the blue-light filtering is on, and you're ready to go. Windows may also use the accurate sunset times in your region to determine the timetable. As long as you switch on Location Services, you'll be able to use it. Finally, you're done!

Benefits of Using the Windows 10 Blue Light Filter

You may think of the light coming from your Windows 10 device as a spectrum, with various hues and intensities. The wavelength and energy of blue light beams are the most extreme. Using a blue light filter, we may get the following results by reducing the amount of blue light entering the camera.

Maintains A Regular Sleep Pattern

Exposure to blue light disrupts your circadian cycles, which is the most crucial effect it has. As a consequence, your sleep schedule will be disrupted. Stress and sleep deprivation may result from not getting enough sleep regularly. Melatonin's effects are likewise reduced by blue light exposure. This hormone helps you fall asleep and keeps your circadian cycle in check.

Makes It Safer to Use Devices at Night

At night or in the darkness, the only time blue light is hazardous is when it is emitted. Blue light, when absorbed by the sun, may be helpful. As a result of its ability to maintain a consistent sleep cycle, blue light is responsible for this. Blue light has a positive effect on mood and cognition throughout the day. It keeps people awake and gives them more energy during the day.

Protects Vision

Blue light's high level of energy hurts your health. Do you get watery eyes by staring at your computer for lengthy periods? It's because of the strain your eyes are under from the blue light. Macular degeneration, a leading cause of blindness, may potentially occur as a consequence.

The blue light filter is a must-have for children or teens who already use computers and other electronics. They will be able to see well thanks to this. Their macular pigment will not be enough until they are about nine years old, which is why this is. Their eyes naturally filter out blue light because of the macular pigment.

Helps Reduce the Bad Effects of Long-Term Exposure

After six hours of computer use, you may wish to use the blue light filter option. Eye fatigue and headaches are two possible side effects of computer-related visual stress. It might become permanent if you don't do anything about it right now. Whenever feasible, use a blue light filter.


When the Night light is on, the computer's display will change to a yellow hue. The stunning result will wow you. Because your computer emits Blue Light, it does not need third-party protection.
