Are you searching for the right blue light filter for your laptop?

You’re in the right place.

Next, I’ll introduce you to the best blue light filters for laptops.

What is a Blue Light Filter for Laptop?

A blue light filter for laptops can either be a physical barrier that blocks blue light (by filtering light in the 380nm to 495nm range), like screen protectors or anti-blue light glasses, or software that adjusts the display’s color temperature to reduce blue light emission.

Blue Light Filter Screen Protectors for Laptop

A screen protector is a transparent plastic material that covers the display and reflects harmful blue light through a surface coating.

However, many screen protectors have issues with glare. If there’s a light source or window behind you, your computer screen may act like a mirror.

You should also be mindful of the screen protector’s transparency. If the transparency is too low, it can reduce the clarity of the display.

Additionally, some screen protectors don’t adhere well to the screen, which can cause blurriness and make text and images hard to see.

Since screen protectors are designed to fit specific laptop sizes, if you upgrade your laptop in the future, you may need to purchase a new one to match the new screen size.

Summary:

Screen protectors can cause reflection issues, need to fit the laptop’s display size, and may require replacement when upgrading to a new laptop.

Blue light filter glasses

Blue light filter glasses block harmful blue light by either coating the lens surface or using a color-bleeding method. This process involves adding yellow, the complementary color to blue, into the lens material to absorb blue light, effectively reducing blue light exposure.

A good physical blue light filter should mimic natural light. The blue light blocking rate shouldn’t be too high or too low. If it’s too low, it won’t be effective—but if it blocks too much blue light, it can interfere with your circadian rhythm.

Excessive blue light filtering can also cause significant color distortion and lead to visual fatigue. Ideally, the blue light blocking rate should be between 60% and 70%.

One downside of physical blue light filters is that they can be expensive and are often made from materials that aren’t very durable, meaning you might need to replace them frequently.

Using physical filters also impacts screen colors, especially for images. Another limitation is that the blue light filtering effect can’t be adjusted. If you need high color accuracy for certain tasks, this can be frustrating.

Software applications don’t have this issue, as they allow you to adjust the blue light blocking rate to your needs.

SUMMARY
Expensive and easily damaged, Cannot adjust the blue light filter value

If you want to compare the blue filter application with a physical blue light filter (such as glasses), then you will find that a physical blue light filter will significantly reduce the image quality and color quality, and the effect of filtering blue light is not Regulated, far from being like a class of applications.

Blue light filter software for laptop

CareUEyes is one of the most popular blue light filter apps for laptops.

You can adjust the amount of blue light emitted from your screen by clicking or dragging the color temperature slider. Moving the slider to the left reduces blue light, making the screen appear redder and dimmer. Moving it to the right increases blue light, making the screen look bluer and brighter.

Like most blue light filter apps, CareUEyes reduces blue light, eases eye strain, helps prevent eye issues, and can be used at night to minimize blue light’s impact on sleep.

With CareUEyes, users can work comfortably for extended periods without putting excessive strain on their eyes or body.

Unlike physical screen filters, CareUEyes works on multiple monitors, regardless of their size or configuration, eliminating the need to buy hardware like screen filters.

CareUEyes automatically adjusts the blue light blocking rate based on sunrise and sunset times. Reducing blue light exposure at night compared to daytime helps promote better sleep.

Physical blue light filters cannot adjust the amount of blue light filtering at will.

CareUEyes provides eight preset modes, you can switch between pause, health, game, movie, office, editing, movie, reading, and customization at will.

Each of these options provides a slightly different experience for the user and changes the brightness of the display to suit a specific task or activity. If you are not satisfied with the preset mode, you can also modify the preset mode.

• • Health model

Health mode is suitable for people who are sensitive to light. This mode has the lowest color temperature among the eight preset modes, that is, the model with the strongest blue light filtering effect.

• • Game mode

Generally, people have higher requirements for the realism of the color of the game screen when playing games. Under the premise of not affecting the game experience, this mode makes subtle adjustments to the color temperature and screen brightness.

• • Movie mode

The display of videos and movies is usually most affected by the blue light filter. Fortunately, the movie mode setting on this blue light filter is very good. When watching movies on a laptop late at night, the color of the screen will not be seriously distorted, and there will be an unsightly orange glare.

• • Office mode

This mode is suitable for daily office use. Working in this mode, your eyes will not get tired easily.

• • Edit mode

This mode is very useful for programmers who need to work at night, because it inverts the color of the screen, which can remove a large area of white background, thereby greatly reducing blue light.

• • Reading mode

The reading mode makes all colors black and white like electronic ink devices, suitable for reading.

• • Custom mode

Users can customize a mode and freely change the color temperature and brightness.

SUMMARY
The price is cheap, the blue light filter value can be adjusted automatically, and it can be used on multiple laptops

Conclusion

There are many options for blue light filters for laptops, blue light filter screen protectors and blue light glasses have their own advantages and disadvantages, but blue light filter software (CareUEyes) is simpler and more practical. It can provide you with the greatest value at the lowest cost.

When a window appears darker or grayscale, a close button will be displayed. You can click on the close button on the right side of the toolbar to restore the original color.

Alternatively, you can disable the toolbar and use hotkeys to switch between window dark mode or grayscale mode.

The increasing use of digital devices has raised concerns about exposure to blue light, also known as high-energy visible (HEV) light, which is emitted by screens and can negatively impact our health.

As a result, using blue light filters has become essential in today’s digital age.

This article examines the benefits of using a blue light filter on your PC, with a close look at CareUEyes, one of the most popular software options available.

In addition, it provides instructions on enabling blue light filtering in Windows 11, covering both the built-in Night Light feature and a more effective alternative: CareUEyes.

Windows 11 Night Light: Blue Light Filter for Windows 11

The latest version of Windows, Windows 11, includes a feature called Night Light.

This feature is designed to reduce the amount of blue light emitted from your screen, which can cause eye strain and interfere with your sleep patterns.

Night Light works by adjusting the screen’s color temperature, decreasing blue light and boosting warmer tones, resulting in a display with a redder, warmer tint.

This helps protect your eyes and may improve your sleep cycles. Users can also customize and schedule the Night Light feature to suit their preferences.

How to Enable the Night Light Feature

To turn on the blue light filter in Windows 11, follow these steps:

1. Click the Windows icon on the taskbar, then select the Settings gear icon. (You can also open the Settings app with the shortcut: Win + I)
2. When the Windows Settings menu appears, click on System.

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.

Schedule night light

7. If you want to schedule the night light to turn on and off automatically at specific times, toggle the Schedule night light switch to On and click on the Set hours button.

8. Modify the night light turn on and turn off time as per your requirement.

9. If you need to turn on and off the night light automatically according to the local sunset and sunrise time, toggle the Schedule night light switch to On and click on the Sunset to sunrise button.

Disadvantages of Night Light Mode

1. Color Accuracy Issues
   The first drawback of Windows 11’s Night Light mode is that it affects color accuracy. If you’re using Night Light for the first time, your eyes might need some time to adjust, but after a while, they’ll adapt. However, if you’re editing videos or photos, you may need to turn off Night Light to maintain accurate colors. Constantly switching Night Light on and off can become a hassle.
2. Limited to One Color Temperature
   The second downside is that Windows 11 Night Light only lets you set one color temperature. Different activities might require different color settings; for instance, people might prefer a lower color temperature for reading emails or browsing the web but wouldn’t want it to affect the screen when gaming or watching movies. It would be more convenient if Night Light allowed multiple color temperature presets for different scenarios.
3. No Hotkey Support for Adjusting Color Temperature
   Another disadvantage is that Night Light mode doesn’t support hotkeys for quickly adjusting the color temperature. Typically, it takes about six steps to change the temperature, which can be inconvenient if you need to adjust it frequently.
4. No Separate Day and Night Settings
   Windows 11’s Night Light also doesn’t allow different color temperature settings for day and night. You have to manually adjust the color temperature at sunrise and sunset.For those looking to improve sleep, it makes sense to turn on Night Light only after sunset. However, for users who want to protect their eyes from blue light during the day, it’s necessary to keep Night Light on, even though you typically don’t need as much blue light filtering during the day as you do at night. Having separate settings for day and night would be more practical.

A Better Third-Party Alternative

To overcome these limitations, you can install third-party software like CareUEyes. Like Windows 11 Night Light, CareUEyes adjusts color temperature to filter blue light, but it works on older versions of Windows, including XP, Windows 7, and Windows 8.

CareUEyes: Easier to Use Than Night Light

1. Eight Built-In Color Temperature Modes
   CareUEyes includes eight preset modes, each designed for different scenarios. When using it for the first time, you can explore each mode to find the one that best fits your preferences and screen habits.

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 11 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.

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.

Is a Yellow Screen Better for Your Eyes?

A yellow screen effectively reduces blue light emitted by the screen, alleviates eye strain, and can even help improve sleep quality.

If you’re unfamiliar with the dangers of blue light, you might not see the necessity of using a yellow-tinted screen.

What is Blue light?

Blue light is high-energy visible (HEV) light with a wavelength between 400nm and 480nm. It has a short wavelength and is part of the visible light spectrum.

Why is blue light Harmful?

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 Does a Yellow Screen Reduce Blue Light?

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.

Should You Lower Color Temperature and Brightness as Much 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.

How to Find the Right 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.

Conclusion: Protect Your Eyes and Sleep Better with a Yellow Screen

Switching to a yellow screen or using blue light filter software is one of the easiest ways to reduce digital eye strain, improve focus, and promote better sleep—especially if you work late into the night. By reducing blue light exposure, your eyes stay more comfortable, and your body can maintain a healthier sleep-wake cycle. Tools like CareUEyes make it easy to apply these changes with just a few clicks. Start protecting your eyes today and enjoy a more relaxing screen experience—day and night.

Computers have permeated every aspect of our lives. Whether in the workplace, at home, or at school, the use of computers is now nearly obligatory. For many of us, spending time in front of a screen is almost unavoidable.

Computer-Related Health Issues

It’s now evident that prolonged computer use can lead to a range of vision-related problems collectively known as computer vision syndrome (CVS) or digital eye fatigue. In fact, spending just two hours on the computer in a single day gives you a 90% chance of developing computer vision syndrome (CVS).

Many of us have experienced at least some symptoms of CVS, including eyestrain, headaches, dry eyes, blurred vision, and neck pain.

Apart from causing Computer Vision Syndrome (CVS), computers emit a considerable amount of blue light, which can trigger various health problems. Prolonged exposure to excessive blue light can harm the eyes and potentially contribute to the onset of age-related macular degeneration (AMD). Moreover, it disrupts sleep patterns, leading to insomnia and disturbances in your circadian rhythm. Using a mobile phone or computer before bedtime heightens the risk of insomnia.

Hence, safeguarding your eyes is paramount whenever you’re on the computer, and one method to achieve this is by employing a computer screen protector.

Computer screen protectors are engineered to diminish blue light, glare, and regulate screen brightness, shielding our eyes from electronic screens. They can manifest as physical devices or software.

Anti-Glare Computer Screen Protectors for Eye Protection

You can utilize a top-notch anti-glare computer screen to diminish glare from your computer monitor. These anti-glare filters are available in two frame designs: flat or wraparound. The selection between them relies on your display style and personal preference. With either choice, you can significantly minimize the glare reflected from the screen into your eyes.

Pros: Effectively minimizes glare and blocks ultraviolet rays.

Cons: Installation can be tricky, often leading to bothersome dust and bubbles during the process. Moreover, they do not filter blue light.

Compared to physical screen protectors, CareUEyes is the better choice. Its blue light filtering is more powerful and comes with additional eye protection features. By adjusting the color temperature, it effectively reduces blue light and creates a warmer, more comfortable screen appearance.

   Glare happens when too much light enters your eyes, disturbing your eye comfort. Adjusting both the screen color temperature and brightness can effectively diminish glare.

   Extended computer usage without breaks is also a significant cause of eye fatigue. It’s advised to follow the “20-20-20” rule, which recommends taking regular breaks. Enable the Timer function on CareUEyes to receive intelligent reminders prompting you to take breaks.

    
    

Remember to blink!

Blinking helps keep the eyes lubricated; otherwise, they can become dry. When you gaze at the screen for long periods, you might forget to blink. Hence, it’s crucial to consciously make an effort to blink, as it promotes eye health. This habit complements the 20-20-20 rule.

Night Light, introduced in the Windows 10 Creators Update, reduces blue light emissions by adjusting your screen to warmer colors. This makes it easier on your eyes and can help improve sleep quality. Here’s how to turn Night Light on or off in Windows 10.

Are you searching for a blue light filter for your computer screen? You might be aware of some of the risks associated with blue light.

Blue light emitted by computer screens can significantly affect both eye health and sleep quality. Prolonged exposure to blue light can lead to digital eye strain, resulting in symptoms such as dryness, irritation, and difficulty focusing. Moreover, blue light interferes with the production of melatonin, the hormone responsible for regulating sleep. This disruption can make it harder to fall asleep and maintain a healthy sleep cycle, potentially leading to fatigue and decreased overall well-being.

Software-based blue light filters work by adjusting the color temperature of your computer screen to reduce the amount of blue light emitted. These filters typically use algorithms to shift the display’s colors towards warmer tones, such as amber or orange, especially during evening hours. This shift not only decreases blue light exposure but also enhances visual comfort, making it easier on the eyes. Many of these filters can be customized, allowing users to set specific times for activation and adjust the intensity according to their preferences, ultimately promoting better eye health and improved sleep quality.

Hardware-based blue light filters work by physically blocking or absorbing blue light before it reaches your eyes. These filters are typically applied as screen protectors or overlays that are placed directly on the display. They use specialized materials designed to filter out blue light wavelengths while maintaining the clarity and brightness of the screen.

Recommend a great software-based blue light filter for screen：CareUEyes

CareUEyes filters blue light by adjusting the color temperature, because the higher the color temperature of the computer screen, the more blue light is emitted, and vice versa.

Therefore, with CareUEyes you can adjust the blue light blocking rate arbitrarily (but the physical filter device cannot adjust it).

Why do I emphasize this point? Because it is very useful.

In the daytime, the color temperature should match the external light, and 5000K-5500k is recommended. This can eliminate the damage to the eyes caused by the accumulation of blue light energy, and at the same time, there is an appropriate amount of blue light to keep people awake during the day and be more energetic to deal with this day’s things.

At night, the color temperature should be set to match the light in your room, and a low temperature of 3700K-5000K is recommended. At this time, we don’t need blue light to suppress melatonin secretion, and the body does not need to be in a state of excitement. The beneficial blue light during the day has been transformed into harmful blue light at this time.

On the contrary, we need to secrete melatonin to a certain concentration, which will help us fall asleep and ensure good sleep quality.

Through the comparison of blue light intake at different time periods during the day and night, the changes in the concentration of melatonin can be better adjusted, and the quality of night sleep can be further improved.

As long as you turn on the sunrise and sunset functions, CareUEyes can automatically switch between the two modes for you according to the time of sunrise and sunset.

Eight preset modes allow you to easily and quickly filter blue light.

CareUEyes provides eight preset modes, you can switch between pause, health, game, movie, office, editing, movie, reading, and customization at will.

Each of these options provides a slightly different experience for the user and changes the brightness of the display to suit a specific task or activity.

If you are not satisfied with the preset mode, you can also modify the preset mode.

Adjustable screen brightness provides further protection for your eyes.

CareUEyes has the function of adjusting the brightness of the screen to protect the eyes more comprehensively.

For many monitors, adjusting the screen brightness is very troublesome. Using CareUEyes can easily adjust the screen brightness. Not only can you adjust the brightness by dragging the progress bar on the main interface, but you can also use the hotkey to adjust it more conveniently.

Timed reminders for breaks are essential for eye protection

Regular rest is an effective way to prevent eye fatigue. The famous 20-20-20 rule: Every 20 minutes, look at an object 20 feet away for 20 seconds.

If you are busy with work, you may not have time to stop and rest frequently, because this may reduce your work efficiency.

CareUEyes reminds you to rest for 5 minutes every hour by default, but the interval and duration of rest can be customized.

This is not a simple timer, it can intelligently detect your use of the computer.
For example, if you leave the computer midway, the timer will automatically pause. After a certain period of time, the timer will restart when you return to the computer.

Many people, because of their busy work or minors with low self-discipline, know that they cannot leave the computer to take a break when it is time for a break.

For the above-mentioned people, you can use CareUEyes’ forced rest mode and turn on the password protection function, so that you will not miss the rest.

CareUEyes is a product you will love after using it.
