Blue Light Filter in Windows 10: Understanding Its Benefits and How to Enable It

The use of digital devices has become an essential aspect of our daily routine, but it has also brought about new health concerns, particularly related to the blue light emitted from these devices. Blue light is a high-energy visible (HEV) light with a short wavelength that can disrupt our natural sleep patterns, causing various symptoms such as eye strain, headaches, and insomnia. Fortunately, Microsoft has integrated a blue light filter into its latest operating system, Windows 10, to help alleviate these effects. This article will delve into what blue light entails, its impact on our well-being, and the steps to activate the blue light filter on Windows 10.

Next, I will show you how to enable blue light filtering in Windows 10. Includes the night light feature that is incorporated in Windows 10 and a more perfect alternative app: CareUEyes.

What is Blue Light?

Blue light is a type of light that is emitted from electronic devices like computers, smartphones, and televisions. It has a shorter wavelength than other types of light and is part of the high-energy visible (HEV) light spectrum. This type of light has been found to interfere with our circadian rhythm, which is our body’s internal clock that regulates our sleep-wake cycle.

Windows 10 night light: Blue  light filter for Windows 10

The latest version of Windows 10 now includes a feature known as night light, which aims to minimize the amount of blue light emitted from the screen. This is intended to reduce eye fatigue and help maintain regular sleep patterns. The night light mode works by adjusting the color temperature, making the screen appear warmer and enhancing reddish hues while reducing blue light.

You can also customize the Night Light settings by clicking on the Night light settings option. From here, you can set a schedule for when Night Light should turn on and off, as well as adjust the color temperature to your liking.

How to enable the night light feature

To enable the blue light filter in Windows 10, you need to perform the following steps:
1. From the Start menu, click on the Settings button.

2. When Windows Settings appears on the screen, click on the System option.

3. Click on the “Display” option.

4. Click on the night light settings.

5. Toggle the night light switch to On.

6. By sliding,  you can adjust the color temperature as per your requirement.

Disadvantages of the night light mode

1. The first disadvantage of Windows 10 night light mode is that it changes color accuracy. If you are using the night light feature for the first time, your eyes may not get used to it, but after a while, your eyes will slowly get used to it. However, when you are editing videos or photos with Windows, you may need to turn off the night light to maintain a high level of color accuracy. But it is a bit of a hassle to manually turn on and off the night light frequently.

2. The second disadvantage of Windows 10 nightlight mode is that you can only set one color temperature mode. But people may need different color temperatures in different scenarios, for example, people can accept lower color temperature when dealing with emails or reading web pages, but usually don’t want the color of the screen to be affected too much when playing games or watching movies, so it will be easier to use if nightlight can set multiple color temperature modes.

3. The third disadvantage of Windows 10 nightlight mode is that it does not support hotkeys to adjust color temperature. According to the usual steps, you need to go through six steps to open the color temperature adjustment.

4. The fourth disadvantage of Windows 10 night light mode is that it can not set different color temperatures for day and night, you need to manually adjust the color temperature again at sunset and sunrise.

For people who just want to improve their sleep, they can turn on the night light only after sunset, but for people who want to reduce blue light to protect their eyes, they also need to turn on the night light feature during the day, but usually, they don’t need to filter as much blue light during the day as they do at night, so it’s necessary to set different color temperature for day and night.

A more perfect third-party alternative

If you want to overcome the above disadvantages of Windows 10 night light, you can install a third-party software called CareUEyes. CareUEyes filters blue light by adjusting the color temperature just like Windows 10 night light, but it not only supports Windows 10 but also supports installation on XP, Windows 7, and Windows 8.

CareUEyes is easier to use than the night light feature

1. Eight built-in color temperature modes for you to choose

CareUEyes has eight modes for you to choose from, you just need to experience each mode one by one when you use it for the first time, and you can find the most suitable model for you.

2. Convenient and quick to adjust the color temperature

If you are not satisfied with the default mode, you can either adjust the color temperature through the slider on the main interface of CareUEyes or customize the hotkeys to adjust the color temperature.

3. You can set different color temperatures for day and night

You just need to turn on the sunrise and sunset features of CareUEyes to set different color temperatures for day and night, and CareUEyes will automatically adjust the color temperature for you at the sunrise and sunset time you set.

4. Powerful customization rules

You can customize the rules to enter the specified mode when using an application, for example, you can specify to pause the color temperature adjustment when using Photoshop, i.e. enter Pause mode, and enter the game mode when running the game CS: GO.

5. More eye protection features

CareUEyes is not just a blue light filter, it can also adjust the screen brightness, focus, and remind to take regular breaks, it is a multi-feature eye protection software.

Conclusion

The Windows 10 night Light is a simple blue light filter, if you need a more powerful and easy-to-use blue light filter with more comprehensive protection for your eyes, recommend you to install CareUEyes.

CareUEyes: A Comprehensive Blue Light Filter Solution

CareUEyes is a Windows 7 blue light filter, which helps prevent eye fatigue, relieve eye pain and vision problems. It filters blue light by adjusting the color temperature, so you can freely control the filter intensity of blue light. The lower the color temperature, the less blue light.

CareUEyes is similar to the Night light on Windows 10 / Windows 11. You can use it as windows 7 Night light, but it is definitely better than the Night light.

It has eight preset modes, suitable for eight different usage scenarios. Appropriate color temperature is preset for each, but you can also adjust the color temperature according to your needs.

Three ways to filter blue light

1. Drag or click the color temperature slider on the interface. Drag to the left to decrease the color temperature(reduce the blue light), and to the right to increase the color temperature (increase the blue light).

2. Using hotkeys

3. Select the color temperature in the tray right-click menu

Lightweight and easy-to-use blue light filter

CareUEyes can easily help you achieve intelligent blue light filter adjustment. Some software uses overlay translucent windows to filter blue light, but CareUEyes directly controls the display’s RGB value, which ensures compatibility with other software. You can also set the CareUEyes blue light filter adjustment feature to be disabled when a special program is running (for example, while running photoshop, to restore real color).

Unlike other blue light filter software on windows 7, CareUEyes has higher performance. It only needs 5M of memory at runtime, and it does not consume too much CPU time. And the package of CareUEyes is only 2M. I believe this is your best choice.

Sunrise and sunset feature

Although blue light is harmful to the eyes, proper blue light irradiation is beneficial to people during the day. Blue light can keep people awake and have the energy to finish work or study. Therefore, if you are not a person with extremely sensitive eyes, you only need to filter a small part of the blue light during the day and restore the light of the computer screen to light similar to sunlight.

But at night, blue light becomes very harmful, you need to filter more blue light to prevent sleep from being disturbed by blue light. Excessive exposure to blue light at night will cause sleep problems. Because blue light inhibits the production of melatonin in the body. Melatonin is a hormone produced by the pineal gland. It helps your body know when to sleep and wake up. (External Factors that Influence Sleep)

According to people’s different needs for blue light day and night, CareUEyes provides sunrise and sunset feature. Compared with the sunrise and sunset, the color temperature and brightness after sunset are lower.

You only need to turn on the sunrise and sunset functions, CareUEyes will automatically help you adjust the color temperature and brightness at sunrise and sunset.

In addition to filtering blue light, more ways to protect your eyes

1. Follow the “20-20-20” principle

Every time you watch the screen for 20 minutes, raise your eyes and look at a place 20 feet away for at least 20 seconds.

However, many people often forget to take a break due to their busy schedules. CareUEyes can remind you to take a break regularly. It is not a simple timer, it is far more intelligent than you think.

CareUEyes can intelligently analyze the time you actually use the computer, and when you actually work on the computer for the predetermined time, it will remind you to take a break.

2. Set the appropriate brightness for the screen

Don’t make your screen too bright, because the brighter the screen, the more blue light will be emitted, and too bright screen light is also a direct stimulus to the eyes and easily leads to eye fatigue.

Use CareUEyes to easily adjust the screen brightness. You can adjust the brightness in the program interface or use the hotkeys to adjust.

Many people call the night light feature on Windows 10 as night mode, which can reduce blue light, reduce eye strain, and promote sleep.

The night mode is another term used for the dark mode, which is a feature offered by Windows. This feature enables you to alternate between light and dark themes. Once you activate the dark mode in Windows, the interface will switch to a dark theme.

The default setting for most applications is the light mode, which means that dark text is displayed on a light background. The dark mode displays white text on a black background.

Dark mode is designed to decrease the amount of light emitted by a device’s screen while still maintaining sufficient color contrast for readability. This feature can help to reduce glare, alleviate eye strain, and improve the comfort of reading. If you intend to read e-books or edit documents on your computer, you may want to try switching to night mode to see if it provides a more suitable experience.

How to enable dark themes?

If you need to edit documents at night, then CareUEyes’ editing mode is perfect for you. Because it can invert the colors so that white becomes black and black becomes white. So it is perfect for editing documents or for programmers to use when programming at night.

Because most applications have light themes by default, they will become black themes after color inversion. Different from the dark mode that comes with Windows, the editing mode of CareUEyes is suitable for all applications, and it can reverse the background color of all applications.

Different from the general dark theme, the dark theme of CareUEyes is not pure black, but dark gray.

Overview:

To minimize the glare from your computer monitor, you can opt for a high-quality anti-glare computer screen.

These screens come in two frame designs – flat or wrap – and the choice between them depends on your display style and personal preference.

Regardless of the frame design, these screens effectively block all UV rays that are reflected from the screen into your eyes.

By using an anti-glare computer screen, you can effectively reduce eye strain.

Features:

　　Look for an anti glare computer screen with the following features:

• Optical glass.

　　High quality optical glass is superior to plastic.

• Anti-reflective coating.

　　A good glass filter has a multi-layer anti-reflective coating on one or both sides of the glass looking for a filter that provides up to 95% or 99% glare reduction.

• Transmission.

　　There are a variety of light transmissions in the anti glare computer screen, from about 30% transmission to 65% or higher.

　　The intensity of ambient light in the work area helps determine the level of transmission that works best for you – the greater the glare, the lower the transmission you may need to reduce glare on the display.

• Anti-static.

　　Removing excess static electricity from the computer screen is important to help minimize dust accumulation on your computer screen, which can reduce the legibility of characters and look for anti glare computer screen with anti-static features.

• Easy to clean the coating.

　　Anti-reflective coatings show fingerprints and can be difficult to remove. Look for an anti glare computer screen with easy-to-clean feature, just clean the filter with water and a soft cloth.

• ISO 9241-7 compliance.

This will ensure that the filter you purchased has passed the highest standard glare reduction test.

Disadvantages of anti glare computer screen:　　　

• 　　Can’t filter blue light
• 　　Can’t adjust display brightness
• 　　Can’t change your viewing habits
• 　　Different production standards may cause eye fatigue
• 　　Will distract users

Other options

While screen protectors can serve as anti-glare devices, they cannot alter one’s viewing behavior.

To alleviate eye strain, there are alternative methods beyond simply using a computer screen.

Utilizing computer software is one such option that can aid in reducing eye strain.

　　For example, CareUEyes is an eye protection software that filters 90% of the blue light and glare by adjusting the color temperature and brightness of the display, it also has a timed reminder rest function, try to use the timer to ensure that every 45 minutes away from the screen, get up and walk around Try to focus your eyes further, and its price is much lower than the anti-glare filter device, which may be the best choice.

Do you observe that a growing number of individuals prefer to set their computer screens to warmer hues, with some even appearing yellow? Is there any benefit to using a warm screen for the eyes?

One instance is the Night Shift mode on an iPhone, which changes the screen’s color temperature to a warmer yellow.

The Night Light feature, present in both Windows 10 and Windows 11, modifies the screen’s color temperature to a warmer yellow, providing eye protection.

However, there are other software options for eye protection on Windows, such as CareUEyes, which also allows users to adjust the color temperature.

Yellow screen is better for eyes

The yellow screen can effectively reduce the blue light emitted by the screen, relieve eye fatigue, and even help you fall asleep better at night.

If you haven’t heard the dangers of blue light, you may not like a yellow screen.

What is Blue light?

Blue light is light with relatively high energy with a wavelength between 400nm and 480nm. It has a shorter wavelength and is part of the visible spectrum.

Why is blue light bad?

Blue light can penetrate the lens directly to our retina, causing the atrophy or even death of retinal pigment epithelial cells. The death of light-sensitive cells will result in decreased vision or even complete loss of vision. This damage is irreversible.

Blue light can also cause age-related macular degeneration, which can lead to permanent vision loss.

The lens of the human eye will absorb part of the blue light and gradually become cloudy to form cataracts, and most of the blue light will penetrate the lens, especially children’s lenses are clearer and cannot effectively resist the blue light, which is more likely to cause macular degeneration and cataracts.

Due to the short wavelength of blue light, the focus point does not fall on the center of the retina, but a little bit forward from the retina. To see clearly, the eyeballs will be in a state of tension for a long time, causing visual fatigue. You may experience symptoms such as eye fatigue, headache, blurred vision, dry eyes, neck and shoulder pain.

Blue light inhibits the production of melatonin in the body. Melatonin is a hormone produced by the pineal gland, which helps your body know when to sleep and wake up. Usually, at night, your body produces more melatonin. Once the sun starts to go down, the level of melatonin secretion starts to rise. This indicates that the body is ready to fall asleep. When the sun rises, the level of melatonin secretion starts to decrease and the body gradually began to wake up. Excessive exposure to blue light at night and insufficient melatonin secretion in the human body will keep people awake and unable to fall asleep, which causes the problem of insomnia.

Why can the yellow screen reduce the blue light emitted by the screen?

You need to know the concept of color temperature first. The concept of color temperature is based on an imaginary absolute black body, which emits different colors of light when heated to different temperatures, and its objects appear in different colors. Just like when an iron block is heated, the iron block first turns red, then yellow, and finally white. When heated to a certain temperature, the spectral component of the light emitted by the black body is called the color temperature at this temperature, and the unit of measurement is “K” (Kelvin).

If the light emitted by a light source has the same spectral components as the light emitted by a black body at a certain temperature, it is called a certain K color temperature.

For example, some common light sources and related parameters of color temperature: tungsten lamp 2700K; summer noon sun 5500K; cloudy 6500-7500K; candlelight 2000K and so on.

The color temperature calibrated by this method is exactly the opposite of what the general public thinks of “warm” and “cold”. For example, people usually feel red, orange, and yellow are warmer, white and blue are colder, but in fact, red has the lowest color temperature, and then gradually increases are orange, yellow, white, blue, and blue is the highest color temperature.

A light source with a high color temperature appears blue and contains more blue light. A light source with a low color temperature appears reddish-yellow and contains less blue light.

The color temperature of the screen only indicates the spectral components of the light source, not the luminous intensity (the brightness of the screen indicates the luminous intensity of the screen).

Therefore, if we want to reduce the total amount of blue light emitted by the screen, one way is to reduce the blue light component in the spectrum, that is, lower the color temperature and adjust the screen to a yellowish tint. Another method is to reduce the luminous intensity of the screen, that is, to dim the brightness of the screen.

Are the color temperature and brightness as low as possible?

Although reducing the color temperature and brightness of the screen can help us reduce the harmful blue light, the color temperature and brightness of the screen are not as low as possible. Because the color temperature is too low, the screen will turn red, which will make the screen difficult to see. Too low screen brightness will also make the screen difficult to see, increasing eye fatigue. We need to keep the color temperature and brightness of the screen within an appropriate range.

What are the appropriate color temperature and brightness?

CareUEyes has the function of adjusting the color temperature and the screen brightness. It designs eight preset modes according to the most commonly used scenes in people’s daily life. The eight preset modes are health, games, movies, office, editing, reading, customization, and pause modes.  They have preset suitable color temperature and brightness so that you can quickly find the color temperature and brightness that suit you.

The healthy mode has the lowest color temperature among all modes, and the screen looks slightly yellow. Your eyes may not adapt well at first, but soon you will find that such a screen looks softer, your eyes will no longer be tingling, dry, and tired.

Although blue light is harmful to the eyes, proper blue light irradiation is beneficial to people during the day. Blue light can keep people awake and have the energy to finish work or study. Therefore, if you are not a person with extremely sensitive eyes, you only need to filter a small part of the blue light during the day and restore the light of the computer screen to light similar to daylight.

But at night, blue light becomes very harmful, you need to filter more blue light to prevent sleep from being disturbed by blue light.

According to people’s different needs for blue light day and night, CareUEyes provides sunrise and sunset functions. Compared with the sunrise and sunset, the color temperature and brightness after sunset are lower.

You only need to turn on the sunrise and sunset function, CareUEyes will automatically help you change the color temperature and brightness at sunrise and sunset.

Summary:  The yellow screen can reduce blue light and protect our eyes. You can use CareUEyes to help you adjust the color temperature and brightness.

The Night light function is utilized to decrease the amount of blue light emitted on Windows 10/11 operating systems.

This feature can safeguard our vision from blue light and enhance our sleep quality. However, it is exclusively accessible on Windows 10/11 and is not compatible with other operating systems such as Windows XP, Windows 7, Windows 8, and Vista.

In the event that you desire to utilize Night light on Windows 7, an alternative option is to employ CareUEyes.

Compared with Night light, CareUEyes is not just software that can filter blue light, but also has more eye protection features.

3.  Customize rules

4. Focus mode

 Focus mode helps you to read with greater concentration.

5. Break timer

Staring at a computer screen for a long time can cause computer vision syndrome, including eye fatigue and discomfort, dry eyes, red eyes, blurred vision, headache, neck and shoulder pain, and so on.

Because humans usually blink about 15 times per minute. But when we stare at the computer or mobile phone screen, the number of blinks will be greatly reduced, which may lead to dry eyes and fatigue.

Sitting in the same position for a long time can cause tension and pain. Our back, neck, shoulders, and arms will feel the tension.

Taking a break every once in a while to look at distant objects can greatly reduce the symptoms of eye fatigue. The most well-known is the 20-20-20 rule, which means looking at a place 20 feet (6 m) away from you every 20 minutes for 20 seconds.
