Blue light from computer screens can cause eye strain and disrupt sleep patterns. Fortunately, there are several easy ways to reduce blue light exposure on your Windows PC or laptop. This guide will show you how to use built-in Windows settings and other methods to filter blue light and protect your eyes.

What is Blue Light?

Blue light is a high-energy visible light with short wavelengths on the color spectrum. While the sun is the main source of blue light, digital devices like computer monitors, smartphones, and LED lights also emit significant amounts.
Key facts about blue light:
  • Falls in the 380-500 nanometer range on the visible light spectrum
  • Has higher energy than other visible light colors
  • Can penetrate to the retina at the back of the eye
  • May contribute to digital eye strain and sleep disruption
While moderate blue light exposure during the day is normal, excessive exposure, especially at night, can be problematic.

Why Reduce Blue Light?

There are several important reasons to limit blue light from your computer screen:
  • Reduces digital eye strain and fatigue
  • Prevents disruption of your natural sleep-wake cycle
  • May lower risk of long-term retinal damage
  • Improves overall eye comfort during computer use
By filtering blue light in the evening hours especially, you can maintain better sleep patterns and reduce eye strain from prolonged screen time.

How to Use Windows’ Built-in Blue Light Filter

Windows 10 and 11 have a built-in blue light reduction feature called Night Light. Here’s how to enable and customize it:
  1. Open the Start menu and go to Settings
  2. Click on System
  3. Select Display
  4. Toggle on Night Light
  5. Click Night Light settings to customize
In the Night Light settings, you can:
  • Adjust the blue light filtering strength
  • Set a schedule for automatic activation
  • Turn it on manually as needed

Other Ways to Reduce Blue Light on Your PC

Beyond the built-in Windows setting, here are some additional methods to limit blue light:

Use Blue Light Filtering Software

Third-party apps like f.lux and Iris offer more customization options for filtering blue light. These allow you to:
  • Fine-tune color temperature settings
  • Create custom schedules
  • Adjust settings based on your location’s sunrise/sunset

Enable Blue Light Filter on Your Monitor

Many modern monitors have built-in blue light reduction settings. Check your monitor’s on-screen display menu for options like:
  • Low Blue Light mode
  • Eye Saver mode
  • Reading/Night mode

Use Blue Light Filtering Glasses

Special glasses with tinted lenses can block blue light from reaching your eyes. These are especially useful if you use multiple devices or can’t adjust display settings.

Adjust Your Display Settings

Even without special filters, you can reduce blue light by:
  • Lowering your screen brightness
  • Adjusting color temperature to warmer tones
  • Using Dark Mode in Windows and apps

Best Practices for Reducing Eye Strain

In addition to filtering blue light, follow these tips to minimize digital eye strain:
  • Take regular breaks using the 20-20-20 rule: Every 20 minutes, look at something 20 feet away for 20 seconds
  • Position your screen about arm’s length away and slightly below eye level
  • Reduce glare by adjusting lighting and using an anti-glare screen filter
  • Increase text size and contrast for easier reading
  • Blink often to keep your eyes moist
