Why This Simple Setting Is a Game-Changer
Let’s face it—our eyes weren’t meant to stare at screens for 8+ hours a day. Yet here we are, hopping from Zoom calls to binge-worthy series, often without even blinking (literally). That dry, scratchy, tired feeling you get after a long screen session? Yeah, that’s not just “being tired”—it’s eye strain caused by overexposure to blue light.
But don’t worry, you don’t need to buy fancy glasses or complicated software. The good news is: there’s a blue light filter on Windows, and turning it on can actually make a huge difference in your eye comfort, sleep quality, and overall screen experience.
What Is Blue Light, and Why Should You Care?
The Science in Simple Words
Blue light is part of the visible light spectrum. It’s high-energy and short-wavelength, which means it scatters easily and can penetrate deeper into the eye. The screens we stare at all day—laptops, desktops, smartphones—all emit this kind of light.
Why It’s a Problem
Excessive exposure to blue light (especially in the evening) can mess with your natural sleep cycle, make your eyes feel exhausted, and even contribute to long-term vision issues. That’s why enabling a blue light filter on Windows is one of the easiest health hacks you can implement today.
What Does a Blue Light Filter Do?
When you activate the blue light filter on Windows 10, it gives your screen a slightly warmer, yellowish hue. This reduces the intensity of blue light emitted and eases the stress on your eyes.
If you’ve used your device late at night and had trouble falling asleep after, this is probably why. By using the built-in blue light filter Windows 10 provides, you help your brain transition to bedtime more naturally.

2. Iris
Iris offers more customization than Windows. You can control brightness, color temperature, and even use health presets.

- Makes screen time more comfortable

The Trade-Off: Does It Affect Color Accuracy?

Blue light disrupts circadian rhythms, which are already more sensitive with age.
