Blue Light Filters

Blue light filters can help reduce eye strain looking at monitors. Most devices have a blue-light filtering option available.

Windows and MacOS have their own blue light filters and there are a number of third-party apps that you can use as well.

How to set Blue Light Filters on your Mobile Phone

Third-party alternatives


Free for WindowsMacOS, and Linux platforms, f.lux is a filtering tool that tracks the sun in your local area to make sure that the color temperature of your monitor(s) matches the local light level.

It features the option to turn it off for fullscreen apps (so games and photo-editing aren’t overly affected) and it can even integrate with smart lighting systems if you want to automatically tweak your room lighting at the same time.

Iris mini

A truly lightweight blue-light filter application, Iris mini has no UI, no buttons, and no “confusing options,” just the ability to adjust your monitor’s coloring to best protect your eyes from glare and harmful blue light.

You can manually control it if you wish, but the automatic mode will keep up with where the sun is in relation to your location and automatically adjust your screen’s coloring accordingly.
