What is Safe Eyes?

Safe Eyes is a Free and Open Source tool for Linux users to reduce and prevent repetitive strain injury (RSI). It helps you avoid asthenopia by reminding you to take regular breaks when working for long hours on a computer. You can install SafeEyes on all major Linux distributions out there, this includes but not limited to Ubuntu, CentOS, Fedora, Solus, Arch e.t.c.

Top features of SafeEyes

  1. Smart decisions – SafeEyes is able to sense if you’re screen is idle and postpone the break based on the idle period.
  2. Lock screen – SafeEyes will start to lock the screen and start default screensaver for long breaks
  3.  Extensible with plug-ins – You can easily customize the look and feel of SafeEyes using custom extensions.
  4. APIs for developers – SafeEyes gives developers remote control through Remote Procedure Call (RPC) API and command-line parameters.
  5. Notifications – SafeEyes gives loud notifications when the time is up for work or break. This makes it easy to pause and resume work when you’re  some meters away from your computer.
  6. Multi-display support – For dual monitors, SafeEyes locks both during work to ensure your eyes and safe.
  7. Strict break for workaholics – When a strict break is enabled, you cannot skip/postpone breaks unconsciously. This is a good feature for computer addicts.
