The basic rule of computer screen brightness is: the screen brightness is best adjusted to be similar to the brightness of the surrounding environment, not too bright or too dim. 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.

Blue Light Filter Windows 7

Are you looking for a blue light filter Windows 7?

Then you have come to the right place. Next, I will show you how to reduce blue light on Windows 7 in a simpler way.

Blue light filter for Windows 7

 

CareUEyes is a Windows 7 blue light filter, which helps prevent eye fatigue, relieve eye pain and vision problems. It filters blue light by adjusting the color temperature, so you can freely control the filter intensity of blue light. The lower the color temperature, the less blue light.

CareUEyes is similar to the Night light on Windows 10. 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).

2. Using hotkeys

3. Select the color temperature in the tray right-click menu

Lightweight and easy-to-use blue light filter

 

CareUEyes can easily help you achieve intelligent blue light filter adjustment. Some software uses overlay translucent windows to filter blue light, but CareUEyes directly controls the display’s RGB value, which ensures compatibility with other software. You can also set the CareUEyes blue light filter adjustment feature to be disabled when a special program is running (for example, while running photoshop, to restore real color).

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.

blue light filter Windows 7

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.

2. Adjust the brightness of the screen

Don’t make your screen too bright, because the brighter the screen, the more blue light will be emitted, and too bright screen light is also a direct stimulus to the eyes and easily leads to eye fatigue.

Use CareUEyes to easily adjust the screen brightness. You can adjust the brightness in the program interface or use the hotkeys to adjust.

Bule light filter Windows 10

Studies have shown that computer screens emit blue light that is harmful to health. Users who must work long hours on computer screens experience eye strain and headaches. People who are overexposed to blue light at night time also experience circadian rhythm disruptions and difficulty sleeping.

Next, I will show you how to enable blue light filtering in Windows 10. Includes the night light feature that is incorporated in Windows 10 and a more perfect alternative: CareUEyes.

Windows 10 night light: Blue  light filter for Windows 10

A feature called night light has been incorporated in the newer Windows 10 release, designed to reduce the blue light emitted from the screen, reduce eye strain, and maintain normal sleep patterns. Night light mode reduces blue light by adjusting the color temperature to reduce blue light and enhance redder colors, and the screen becomes warmer.

Redder and warmer lights are less harmful to the eyes, and people who use night Light mode tend to have more regular sleep cycles than those who do not use the feature. You can adjust the night light to your liking, and you can schedule it to turn on and turn off at certain times.

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.

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.

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.

 

 

10. If you do not have access to the location of this device, you need to click on Location settings first.

 

11. Click on the Change button.

12. Turn on the location access permission.

Disadvantages of the night light mode

1. The first disadvantage of Windows 10 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 10 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 10 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 10 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 10 night light, you can install a third-party software called CareUEyes. CareUEyes filters blue light by adjusting the color temperature just like Windows 10 night light, but it not only supports Windows 10 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.

What is Advanced Color API

The Advanced Color API is a term used by Windows developers. It uses GPU rendering and supports high dynamic range (HDR), wide color gamut (WCG), and high-precision (bit depth) visual content such as videos, games, and photos. Compared with the Color API, the Advanced Color API has better compatibility and performance.

CaeUEyes calls the Color API by default when adjusting the color temperature and brightness, but the Color API cannot work on some devices and must enable the Advanced Color API. Since it is impossible to accurately identify which devices need to enable the Advanced Color API, there may be a problem that CareUEyes does not work properly on some users’ computers because the Advanced color API features are not enabled.

In order to solve this problem, after the user newly installs CareUEyes, a pop-up will ask the user whether CareUEyes is working properly. If CareUEyes is not working properly, the Advanced Color API will be enabled.

However, there is a shortcoming when the Advanced Color API is enabled. It will cause the color of the picture to turn yellow when taking a screenshot, such as a screenshot below.

Therefore, it is recommended that for users who have enabled the advanced color API, it is best to set a hotkey to quickly disable and enable CareUEyes. You can use the hotkey to disable CareUEyes before taking the screenshot, and then use the hotkey to enable CareUEyes after the screenshot is completed, so that the color of the screenshot will not be distorted.
