Eye Care: Best Free Linux Software to Look after your Eyes

Many people who regularly use computers suffer from eye strain and fatigue. Looking at a monitor for a long time can strain your eyes or can make any other problems you are having with your eyes seem more apparent. There is also research to show that late-night exposure to bright lights can affect sleep quality. This can be mitigated by reducing blue-light exposure.

There are lots of simple steps you can take to reduce eye strain and fatigue. These include adjusting the brightness, contrast settings, and text size displayed, as well as minimizing glare, and ensuring your room has proper lighting. Taking regular breaks is also very important.

Some monitors go further offering various eye care technologies including flicker-free technology, and an ultra-low blue light filter with different filter settings. But even if your display offers eye care technology and it’s well designed e.g. offering hotkeys that let you easily adjust filter settings. there’s still a good case to use a software solution as well. This is because the software typically offers more flexibility, such as the ability to automatically adjust the backlight and screen temperature based on the ambient brightness in your surroundings, or on a time schedule.

If you need color accuracy occasionally, using a hardware solution can be tedious. Good eye care software lets users disable the filter for a specific period of time. That’s extremely handy if you need to only periodically work on tasks where color accuracy is important such as a lighttable and darkroom for photographers.

We recommend four free software solutions below. All but f.lux are released under an open source license. f.lux is freeware.

Your desktop environment may also offer some basic functionality to reduce the amount of blue light emitted. The popular desktop environment GNOME includes a night light feature that makes the screen color warmer. Functionality is quite basic, but it may be sufficient depending on your requirements.

  1. You should absolutely check Gammy! I was using Redshift and I was pretty happy with it, until I tried Gammy about a week ago. Gammy automatically adapts your screen brightness depending on the content it shows (bright pages/images will darken the screen and dark pages/images will make the screen brighter)… You can set it to adapt smoothly in a couple of seconds or you can make it adapt the brightness almost immediately!…
