Protect Your Eyes From Computer Screen Harm with IRIS

Iris is an eye protection software available for Linux, macOS, Windows, ChromeOS, Android, iOS, and Windows Phone. This tutorial will be showing you how to install IRIS on Linux.

How Does Iris Protect Your Eyes From Computer Screen

  • Prevent Eye Strain: IRIS optimizes screen pulsations by controlling the brightness without PWM. You will be able to use your computer for longer without headaches.
  • Reduce eye pain: IRIS will match your screen brightness to the light around you. Using computers will feel like reading a book.
  • Improve Sleep: IRIS will gradually regulate blue light day and night. This will help your body to produce more melatonin at night. You will fall asleep faster and sleep deeper.

Iris is not free, but you can get a 7-day free trial.

    How are you going to alter the brightness of a screen without PWM?

      I don’t know. I’m not the software author. But it does work on all my computers, and you can try it free for 7 days.

  • Very Interesting, as Arte Johnson used to say. I use Redshift which adjusts by time of day, not by ambient light. I might try this out.

  • My eyes thank you @linuxbabe.
    The “micro” version is free and offers four scripts for each situation: default, day, night, reset.

    /opt/iris/Iris: /opt/iris/libs/ version `GLIBCXX_3.4.30' not found (required by /lib/x86_64-linux-gnu/

    This is the error when attempting to install on Ubuntu 22.10 / Wayland.

    If you could revisit this article with additional information for 22.10 it would be great.
