Are you looking for a night mode for PC? I will show you how to turn on night mode on PC.

What is a night mode for PC?

Night mode is a computer setting that allows us to use the computer more comfortably at night. Night mode reduces eye strain and promotes sleep. These settings include filtering blue light, dimming the screen, and displaying a dark theme.

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

Some people call the dark mode as night mode. The dark mode is a setting provided by Windows that allows you to switch between light and dark themes. When you turn on dark mode in Windows, you will see a dark-themed user interface.

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.

The purpose of the dark mode is to reduce the light emitted by the device screen while maintaining the minimum color contrast required for readability. Dark mode can minimize glare to reduce eye strain and make reading easier and more comfortable. If you plan to read e-books or edit documents on your computer, you can switch to night mode to see if it suits you better.

Some people call dimming the screen as night mode. At night, we need to dim the screen brightness, otherwise, the bright screen will cause eye irritation.

How to enable night mode?

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

On Windows 10, to enable dark mode, select Settings> Personalization> Color, then open the “Select color” drop-down menu and select light, dark, or custom.

The default Windows mode will change the background color of the taskbar, start menu, and calendar. The default app mode changes the background color of built-in applications (such as Explorer) and applications you get from the Windows Store.

However, not all applications support dark mode, and many do not. For example, Windows Notepad does not support dark mode. Edge browser can only change the background color of the title bar, toolbar, and menu, but the content of the web page cannot be changed.

Use a night mode app to turn on night mode

CareUEyes is designed for people who like dark screens and want to protect their eyes. It integrates blue light filtering, brightness adjustment, and dark theme functions, and is more powerful and perfect than Windows night mode.

CareUEyes supports all versions of Windows, including Windows XP, Windows 7, Windows 8, Windows 10 and Windows 11. It can dim all screens and monitors; LCD, TFT and LED backlit types. And it supports adjusting the extended screen, if you have two or more extended screens, it can also be adjusted together.

Unlike other night modes for pc, CareUEyes has higher performance. It only needs 5M of memory at run time, requires less CPU time. And the package of CareUEyes is only 2M. I believe this is your best choice.

CareUEyes has eight preset modes, suitable for eight different usage scenarios, and each mode has a corresponding night mode. You only need to turn on the sunrise and sunset functions of CareUEyes. When the preset sunset time is reached, CareUEyes will automatically enter the night mode.

CareUEyes night mode has a lower color temperature and brightness than during the day. When you work in a darker environment it can help you.

How to reduce blue light at night?

You can choose a preset model you like, and then set the time of sunrise and sunset. For example, select the health mode. It has preset the color temperature and screen brightness at night for you. You can also adjust the color temperature and brightness according to your needs.

To change the amount of blue light emitted from the screen, click or drag the color temperature slider. Adjust the slider to the left to decrease the blue light, making the screen appear redder and darker. Adjust the slider to the right to increase the blue light, making the screen appear bluer and brighter.

You can also adjust the color temperature using hotkeys.

How to adjust screen brightness?

To change the screen brightness, click or drag the Brightness slider. Adjust the slider to the left to make the screen darker and to the right to make the screen brighter.

You can also adjust screen brightness using hotkeys.

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. Compared with pure black background and white, the gray background can create a more comfortable contrast experience under the premise of ensuring sufficient text readability and truly reducing the user’s visual fatigue.

To summarize, If your need for night mode is only to filter blue light and reduce screen brightness, then you only need to turn on CareUEyes’ sunrise and sunset feature. If you need a dark theme, then you can choose edit mode.

Have you noticed that more and more people like to set their computer screens to warmer colors, some even look like yellow screens? Does warm screen help eyes?

For example,  iPhone has Night Shift mode, which adjusts the screen to a warmer yellow by adjusting the color temperature of the screen.

Windows 10 and Windows 11 also introduces the Night Light feature, which also adjusts the screen to a warmer yellow by adjusting the color temperature of the screen.

On Windows, there is some better eye protection software than Night Light, such as CareUEyes, which also has the feature of adjusting 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.

CareUEyes has eight preset modes, these preset modes can make it more convenient for you to use. Each preset mode has been set with the best color temperature and brightness. You do not need to repeatedly adjust the color temperature and brightness to find suitable parameters, just select one of the suitable preset modes.

CareUEyes filters blue light by adjusting the color temperature, the lower the color temperature, the less blue light.

The difference between the eight preset modes

Pause
If you need to handle work that requires strict color fidelity, such as Photoshop photos, you can choose pause mode.

Health
This is the first mode preset for all users, it can effectively filter blue light, reduce screen brightness, and it is very comfortable for the eyes in this mode. If you don’t know which mode to choose, use this mode.

Game
Because the game has high requirements on color, the game mode hardly changes the color of the game, but only reduces the screen brightness. It’s just a few tweaks to the brightness, but it’s also more comfortable for the eyes when playing games.

Movie
Movies also have relatively high requirements for color, and the movie mode slightly reduces the color temperature and brightness, which does not affect the color of the movie screen.

Office
If you have just started using CareUEyes and are temporarily unable to adapt to the screen color changes in health mode, it is recommended that you use office mode first. After your eyes get used to it, it is recommended to switch to healthy mode, which can filter blue light more effectively and protect your eyes.

Editing
Editing mode will invert screen colors, suitable for editing Word or Excel, and programmers writing code. If your editor has a white background, such as Word or Excel, you get a black background after inversion. A black background removes most of the blue light.

Compared with the editing mode of other similar software, CareUEyes’ editing mode is more comfortable, because it is not pure black, but close to dark gray. Too pure black makes the background and text form a strong contrast, and the eyes are easy to get tired.

One disadvantage of editing mode is that the color of the picture will be distorted, but generally you don’t care about the color of the picture when editing the text.

Reading
Reading mode turns your screen color into black and white like an e-ink device. It is suitable for use when you are reading text.

Custom
If none of the above seven modes can meet your needs, then you can use the custom mode to customize the color temperature and brightness.

How to adjust the preset color temperature and brightness?

Except for the pause mode, other modes can manually adjust the preset color temperature and brightness.

Adjust color temperature

The first way: Drag or click the color temperature slider to the left to decrease the color temperature, and drag or click the color temperature slider to the right to increase the color temperature. The lower the color temperature, the less blue light the screen emits.

The second way: Set hotkeys to quickly adjust brightness.

The thrid way: Select the brightness value in the tray right-click menu.

How to reset the default parameters?

Click the Reset button to reset the color temperature and brightness of the current mode to the default settings.

How to enable sunrise/sunset mode?

1. Turn on the switch of sunrise/sunset mode

2. Click the Config button to open the sunrise/sunset settings page

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

The basic rule of setting screen brightness is: the screen brightness is best adjusted to be similar to the brightness of the environment, the brighter the environment, the brighter the screen should be. When the surrounding light is very bright, you need to increase the brightness so that you can see the screen clearly. When you are in a dark environment, you need to darken the screen to avoid hurting your eyes.
