- How do I activate the blue light filter?
There have been numerous studies suggesting possible negative impacts of long-term exposure to blue light given off by modern computers, smartphones, and tablet screens. Blue light can play a role in sleep issues, eye strain, dry eyes, and possibly long-term eye fatigue/damage. Fortunately, not only can you enable blue-light filtering on your smartphone, you can do so on Windows 10, 11, Macbooks, Macs, and iPads, too.
In fact, the process is incredibly easy—setup takes just a few minutes. Besides using these options, experts recommend you not use your phone in the dark, or possibly wear glasses that block UV and blue light to protect your eyes.
