blue light filter for windows 11

The increasing reliance on digital devices has raised concerns about exposure to blue light, also known as high-energy visible (HEV) light, emitted by screens, which can have adverse effects on our health.

Consequently, the use of blue light filters has become crucial in today’s digital age.

This article delves into the advantages of using a blue light filter for your PC, offering an in-depth analysis of CareUEyes, one of the most popular software options.

Additionally, it provides guidance on enabling blue light filtering in Windows 11, including the night light feature and a more optimal alternative app: CareUEyes.

Windows 11 night light: Blue  light filter for Windows 11

The latest version of Windows, Windows 11, now includes a feature called night light.

Its purpose is to minimize the amount of blue light emitted from the screen, which can cause eye strain and disrupt sleep patterns.

The night light feature works by adjusting the color temperature of the screen to reduce blue light and enhance warmer colors, resulting in a redder and warmer display.

This is beneficial to eye health and can lead to more regular sleep cycles for those who use it. Additionally, users have the ability to customize and schedule the night light feature according to their preferences.

How to enable the night light feature

To enable the blue light filter in Windows 11, you need to perform the following steps:
1. Click on the Windows icon on the taskbar. Then select the Settings cog. (You can also open the Settings app using the shortcut keys: Win + I)

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.

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 the night light mode

1. The first disadvantage of Windows 11 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 11 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 11 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 11 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 11 night light, you can install a third-party software called CareUEyes. CareUEyes filters blue light by adjusting the color temperature just like Windows 11 night light, but it not only supports Windows 11 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.

How to use CareUEyes to adjust the color temperature and brightness

In this article, I will show you how to use CareUEyes to adjust the color temperature and brightness of the screen.

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

 

Preset modes
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.
