Blue Light Filter Windows 7

Are you looking for a blue light filtering solution for Windows 7?

If you’re seeking guidance on how to reduce blue light on Windows 7, you’ve come to the right place.

As widely known, Windows 7 officially ceased receiving extended support and updates from Microsoft on January 14, 2020. This means that Microsoft no longer provides free security updates and technical support for Windows 7, and features like Night Shift, available on Windows 10, are not accessible. Therefore, we need to use third-party software to achieve blue light filtering on Windows 7.

This article will explore how to make a better choice when it comes to selecting blue light filtering software for Windows 7.

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. Below are some factors to think about when deciding on a blue light filter software.

  1. Customization options: Look for a software that allows you to adjust the level of blue light filtering to your preference. This will give you more control over the level of protection you receive.
  2. Compatibility: Make sure the software is compatible with your operating system and device. Some software may only work with Windows or Mac, while others may not be compatible with your specific model of computer.
  3. Price: Some blue light filter software options are free, while others are paid. Consider your budget and your needs when choosing between free and paid options.

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)
