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.

Furthermore, a blue light filter facilitates extended work sessions in front of a computer, making it an essential tool for individuals who spend extended periods in front of a screen.

Choosing the Right Blue Light Filter Software

Selecting the appropriate blue light filter software from the numerous options available can be overwhelming, but by taking into account some important factors, you can discover the ideal software that suits your requirements. Below are some factors to think about when deciding on a blue light filter software.

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.

Not adjusting the screen brightness accordingly can lead to eye fatigue and vision issues.

Since lighting conditions change frequently, it is important to frequently adjust the screen brightness.

Failing to control the brightness of Windows 7 can have negative effects on both eye health and sleep quality.

Light is one of the most important external factors that can affect sleep. It does so both directly, by making it difficult for people to fall asleep, and indirectly, by influencing the timing of our internal clock and thereby affecting our preferred time to sleep.(External Factors that Influence Sleep)

There are plenty of tutorials on the web for Windows 7 brightness control. But they can’t help you solve the problem, because the brightness adjustment feature of Windows 7 is not always displayed in the control panel, and sometimes even if we update the display driver, the brightness cannot be adjusted.

This is really annoying, but by using the third-party application CareUEyes, you can easily adjust the brightness on Windows 7.

Control screen brightness on Windows 7 the easy way

 

CareUEyes is an eye protection software that can easily help you adjust the brightness on Windows 7. You can use the brightness slider to adjust the brightness. Swipe to the left to decrease the brightness, and to the right to increase the brightness.

Anti glare computer screen

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.

anti glare screen

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.

Yellow screen keep your eyes healthy

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 cause eyestarin

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.

colour-temperature

 

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.

8 modes

More eye protection solutions for CareUEyes

In addition to dimming the screen, there are more ways to protect our eyes, such as blue light filtering and regular breaks:

    • Blue light filter.

      CareUEyes  screen dimmer have a “night mode” setting that adjusts the brightness and contrast of the display to reduce the amount of blue light emitted by the screen. This blue light is known to disrupt sleep patterns and cause eye strain, so reducing its emission can help to reduce these effects.

      Blue light is a high-energy short wave. Continuous exposure to blue light can cause eye fatigue, dryness, pain, and aggravate myopia. Blue light can directly reach the retina of the eye through the passage to the cornea and lens. Long-term exposure to excessive blue light can cause irreversible retinal damage, such as age-related macular degeneration.

      Turning on the blue light filter feature can reduce the damage of blue light to the eyes.

    • Auto Dark

It is a convenient feature that can help to improve the overall experience of using a computer or display device, and is a good choice for anyone who wants to reduce eye strain and improve the comfort of working with a screen.

    • Take regular breaks

      Taking regular breaks from screen use is another important strategy for reducing eye strain and improving the overall comfort of using a computer or other display device. The human eye was not designed to focus on a screen for extended periods of time, and prolonged screen use can lead to eye strain, headaches, and other symptoms.

      Experts recommend taking a break from screen use every 20 to 30 minutes, and looking away from the screen for a few minutes to give the eyes a chance to rest. This can include closing the eyes, looking out the window, or looking at something in the distance. During these breaks, it is also helpful to stretch, move around, and give the body a chance to rest.

      Taking regular breaks can help to reduce eye strain and improve the overall comfort of using a computer or other display device. It can also help to improve productivity, as taking a short break can help to refocus the mind and improve concentration. For these reasons, taking regular breaks is an important part of reducing the effects of prolonged screen use.

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.

But if there are no extra reminders, most people will be immersed in work and forget to take regular breaks. CareUEyes will remind you to take breaks regularly. During these rest periods, you can stand up, walk around and stretch your body to reduce fatigue in your eyes, shoulders, neck, and arms.

Overall, Night light can just only adjust the color temperature, but CareUEyes can not only adjust the color temperature, but also has more eye protection features than Night light, and the user experience is more user-friendly than Night light.
