The whole purpose of Safe Eyes is reminding you to take breaks while working on the computer for a long time. The break screen asks you to do some exercises which will reduce your RSI.
Strict break mode prevents computer addicts from skipping breaks unconsciously. In skip break mode, the user cannot skip or postpone the break.
Workstations with dual monitors are cool to have but Safe Eyes locks all at the same time to relax your eyes during the break.
Safe Eyes shows a system notification before breaks and an audible alert at the end of breaks. Even if you are few steps away from your computer, you can hear the call for back to work.
If you are working with a fullscreen application, Safe Eyes will not bother you. It also can sense if your system is idle and postpone the break based on idle period.
Some long breaks may ask you to leave the computer for a while. In such scenarios, Safe Eyes locks the computer by starting the default screensaver to prevent unauthorized access to your computer.
Plug-in support is one of the cool things Safe Eyes offers. You can customize almost everything using custom plug-ins.
