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

      Auto dark mode is becoming increasingly popular as people become more aware of the effects of prolonged screen use on eye health. 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.

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

In the era of digital dominance, our daily lives are intricately woven with the use of electronic devices such as computers, smartphones, and televisions. However, with this technological integration comes a growing concern about the potential health risks associated with the blue light emitted by these devices. Blue light, categorized as high-energy visible (HEV) light, has been linked to disruptions in our circadian rhythm, leading to issues like eye strain, headaches, and sleep disturbances. Acknowledging these concerns, Microsoft has integrated a blue light filter into its Windows 10 operating system to address these challenges.

This article delves into the concept of blue light, exploring its impact on our well-being and shedding light on the benefits of utilizing the blue light filter available in Windows 10. We will guide you through the process of activating the built-in night light feature, while also introducing a third-party alternative, CareUEyes, which offers a more comprehensive solution to enhance eye protection. As we navigate the intricacies of blue light and its effects, let’s empower ourselves with the knowledge and tools needed to strike a balance between our digital lifestyles and our health.

What is Blue Light?

Blue light is a form of light that is given off by electronic devices such as computers, smartphones, and televisions. It has a shorter wavelength than other kinds of light and belongs to the high-energy visible (HEV) light range. Research has shown that this particular type of light can disrupt our circadian rhythm, which is the internal clock in our bodies that controls our sleep and wake patterns.

Windows 10 night light: Blue  light filter for Windows 10

The latest Windows 10 update includes a feature called night light, which is designed to reduce the amount of blue light emitted from the screen. This feature aims to reduce eye strain and promote healthy sleep patterns by adjusting the color temperature to create a warmer screen appearance and decrease blue light emission.

You also have the option to personalize the Night Light preferences by selecting the Night light settings. Here, you can establish a specific schedule for when Night Light should activate and deactivate, and also modify the color temperature to suit your preferences.

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.

Blue light filter windows 10

 

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

Blue light filter Windows 10

 

3. Click on the “Display” option.

4. Click on the night light settings.

Blue light filter Windows 10

5. Toggle the night light switch to On.

Blue light filter Windows 10

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

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 the default mode doesn’t meet your satisfaction, you have the option to adjust the color temperature using the slider on the main interface of CareUEyes. Additionally, you can also customize the hotkeys to conveniently adjust the color temperature according to your preference.

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

Simply activate the sunrise and sunset features of CareUEyes to customize color temperatures for day and night. CareUEyes will automatically adjust the color temperature according to the sunrise and sunset times you set.

4. Powerful customization rules

You have the option to customize the rules for entering specific modes while using an application. For instance, you can choose to pause the color temperature adjustment when using Photoshop, which activates the Pause mode. Similarly, you can activate the game mode when running CS: GO.

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.

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.

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).

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.

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.

How To Adjust Screen Brightness On Windows 7

How to adjust screen brightness on windows 7 in a simpler way?

adjust screen brightness

The general rule for adjusting screen brightness is to match it with the brightness of the surrounding environment.

In brighter environments, it is recommended to increase the screen brightness for better visibility.

Conversely, in darker environments, it is advisable to decrease the brightness to prevent eye strain.

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.

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.

  • 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.

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

 

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.

Windows 7 Night Light

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 to Win10’s night light, CareUEyes offers a richer set of options. For example, CareUEyes offers many pre-set options, such as Office, Game, Movie, which will definitely help you find your favorite effect in the shortest amount of time.

Editing mode will invert the color, black to white, white to black, use the editing mode to read the text at night, which can greatly reduce blue light and reduce eyesight Stimulus. Win10’s night light does not have this feature.

Reading mode makes your screen look like E Ink screens, which is very suitable for reading text for a long time.

 

2. Independently adjust brightness and color temperature

CareUEyes allows you to adjust brightness and color temperature independently and even has shortcuts specifically designed for it. That is also not available in Win10 night light.

3.  Customize rules

If you sometimes need to process photos, but turning on the night light feature will make the color of the photo distorted. Imagine that you need to turn the night light on and off frequently. It will be a very troublesome period. But using CareUEyes will not have such troubles. You can customize the rules and automatically pause the color temperature adjustment when using photo processing software. You can also customize other rules, such as
automatically entering a default mode when using certain software.

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.
