In today’s digital age, where we spend significant amounts of time in front of computer screens, protecting our eyesight is more important than ever. One effective way to reduce eye strain and discomfort is by investing in an anti-glare computer screen. Here are some tips to help you choose the right one:

1. Screen Material:

When it comes to anti-glare computer screens, the material plays a crucial role. Opt for screens made of high-quality materials such as tempered glass or optical-grade acrylic. These materials not only provide excellent durability but also ensure superior optical clarity, minimizing distortions and enhancing your viewing experience.

2. Reflection Coatings:

Check for advanced reflection coatings on the screen surface. These coatings work by diffusing incoming light, thereby reducing glare and reflections. Look for screens with multi-layered anti-reflective coatings, which effectively minimize glare without compromising color accuracy or image sharpness. Additionally, consider screens with oleophobic coatings that repel fingerprints and smudges, keeping your display clean and clear.

3. Transmission Rates:

Pay attention to the screen’s transmission rates, which determine the amount of light that passes through the screen. Anti-glare screens typically offer varying levels of light transmission, ranging from 30% to 65% or higher. The choice of transmission rate depends on your ambient lighting conditions and personal preferences. In brightly lit environments with high glare, opt for screens with lower transmission rates to effectively reduce glare and improve visibility.

4. Additional Considerations:

• Adjustability: Look for screens with adjustable settings for brightness and color temperature. This allows you to tailor the display according to your comfort and the surrounding lighting conditions.

• Compatibility: Ensure that the anti-glare screen is compatible with your computer model and monitor type. Consider factors such as screen size, aspect ratio, and mounting options to ensure a seamless integration with your setup.

• Warranty and Support: Check the warranty coverage offered by the manufacturer, as well as their reputation for customer support and after-sales service. A reliable warranty ensures peace of mind and protection against any potential defects or issues with the screen.

• ISO 9241-7 compliance:This will ensure that the filter you purchased has passed the highest standard glare reduction test.

What exactly is a night mode for PC?

The night mode feature on our PCs enhances nighttime usability by minimizing eye strain and facilitating better sleep. This feature encompasses options such as blue light filtering, screen dimming, and displaying a dark theme.

Many refer to the night light feature on Windows 10 as the night mode, which effectively reduces blue light exposure, eases eye strain, and supports better sleep.

Night mode, alternatively known as dark mode, is a feature provided by Windows. It allows users to toggle between light and dark themes. Upon activating dark mode in Windows, the interface adopts a darker theme.

By default, most applications are set to light mode, displaying dark text against a light background. Dark mode, on the other hand, presents white text on a black background.

Designed to decrease screen brightness while maintaining adequate color contrast for readability, dark mode aims to reduce glare, alleviate eye strain, and enhance reading comfort. If you’re inclined to read e-books or work on documents on your PC, experimenting with night mode might offer a more suitable experience.

Some individuals refer to screen dimming as night mode. Dimming the screen brightness at night is essential to prevent eye irritation caused by a bright screen.

How to Activate night mode?

On Windows 10, to enable Windows Night Light, navigate to Settings > System > Display > Night Light.

For dark mode, go to Settings > Personalization > Color, then select your preferred color scheme: light, dark, or custom.

The default Windows mode alters the background color of the taskbar, start menu, and calendar, while the default app mode changes the background color of built-in applications (e.g., Explorer) and those acquired from the Windows Store.

However, not all applications support dark mode; many don’t. For instance, Windows Notepad lacks dark mode support, and the Edge browser only allows changes to the background color of the title bar, toolbar, and menu, not the web page content.

Utilize a night mode app to Activate night mode

CareUEyes caters to individuals who prefer dark screens and prioritize eye protection. It incorporates blue light filtering, brightness adjustment, and dark theme functionalities, offering a more comprehensive solution compared to Windows night mode.

CareUEyes is compatible with all Windows versions, including XP, 7, 8, 10, and 11. It can adjust brightness on all screen types—LCD, TFT, and LED backlit—and supports extended screens, enabling adjustment across multiple displays.

Unlike other PC night modes, CareUEyes boasts superior performance, requiring minimal memory (5M) and CPU time. With a compact 2M package size, it’s an optimal choice for users.

CareUEyes offers eight preset modes tailored to various scenarios, each equipped with a corresponding night mode. Simply activate the sunrise and sunset functions, and CareUEyes will transition to night mode automatically at the preset sunset time.

CareUEyes’ night mode features lower color temperature and brightness, ideal for working in dim environments.

How to reduce blue light at night?

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.

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

Disadvantages of the night light mode

1. The night light mode in Windows 10 initially alters color accuracy. It may take time for your eyes to adjust when first using the feature, but they will eventually become accustomed to it. However, if you are editing videos or photos on Windows, you may need to disable the night light to maintain precise color accuracy. This can be inconvenient as you have to manually switch the night light on and off frequently.

2. A drawback of the nightlight mode in Windows 10 is that it only allows for one color temperature mode to be set. However, individuals may require different color temperatures for different situations. For instance, they may prefer a lower color temperature when checking emails or reading web pages, but would not want the screen color to be significantly altered when playing games or watching movies. Therefore, it would be more convenient if the nightlight feature could support multiple color temperature modes.

3. One drawback of the nightlight mode in Windows 10 is that it lacks support for hotkeys to modify the color temperature. To adjust the color temperature, you typically have to follow six steps to access the adjustment settings.

4. One drawback of the night light mode in Windows 10 is that it does not allow for different color temperatures to be set for daytime and nighttime. This means that you have to manually adjust the color temperature again when the sun sets and rises.

For individuals seeking to enhance their sleep, activating the night light after sunset is sufficient. However, those aiming to minimize blue light exposure for eye protection should also utilize the night light feature during the daytime. Nevertheless, the amount of blue light filtration required during the day is typically less than at night, thus necessitating the adjustment of different color temperatures for day and night settings.

A more perfect third-party alternative

To address the limitations of Windows 10 night light, you have the option to install a third-party software known as CareUEyes. CareUEyes functions similarly to the Windows 10 night light by filtering blue light through color temperature adjustments. However, what sets it apart is that it is not only compatible with Windows 10, but also with XP, Windows 7, and Windows 8.

CareUEyes is easier to use than the night light feature

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.

5. More eye protection features

CareUEyes is more than just a blue light filter; it also has the capability to modify screen brightness, enhance focus, and provide reminders for regular breaks. This software offers multiple features for protecting the eyes.

Conclusion

In conclusion, while Windows 10’s night light feature is a step towards mitigating the impact of blue light, its limitations, such as color accuracy adjustments and a lack of customization options, make it less versatile for users with varied needs. For a more effective and user-friendly solution, CareUEyes emerges as a superior alternative. With its eight color temperature modes, convenient adjustments, and the ability to set different temperatures for day and night, CareUEyes not only provides enhanced eye protection but also offers additional features like screen brightness modification and break reminders. For a comprehensive and tailored blue light filter experience, I highly recommend users to opt for CareUEyes.
