When it comes to working long hours staring at computer screens, you may experience downsides such as eye strain or sleep issues.
Eye protection software like F.Lux, Lightbulb or Iris adjusts the brightness of the screen to counter the harmful effects of being exposed to bright light during the workday or while using a computer at home.
Iris is available for Windows, Linux and Mac devices. You can download a free version or buy the pro version for $10 which supports additional functionality and is a lifetime license. The license does include minor builds and bug fixes but not updates.
The free version of Iris supports two different modes and nine different presets. You may set Iris to automatic mode to have the software adjust blue light and brightness automatically. Iris uses your location to change settings accordingly.The Pro version may use the computer's clock instead of the location, and you may set custom night start and end times on top of that.
Manual mode, on the other hand, applies the settings that Iris applies at night all the time.
It is useful if you work in a room without windows or with shutters that are down all the time. Manual mode does not give you control over the process, however. The free version of Iris does not support changing the color temperature manually for instance.
Computer users who work with colors, for instance, when they edit photos or use image editors like Adobe Photoshop, may pause Iris' functionality. There is no option, however, to exclude specific programs from Iris. F.Lux supports such an option. You can whitelist programs, and F.Lux stops its activity whenever you run a whitelisted program.
The free version of Iris supports nine different presets -- called types -- that you may enable. The default is set to health, but you may switch to reading, programming, movie or dark presets at any time.
Some of these require some getting-used-to time. Programming, for instance, inverts screen colors, and reading mode turns any image on the screen into black and white images.
Iris Pro supports additional beneficial features. It lets you manage multiple monitors individually, set a location manually, disable font smoothing, break reminders, and use additional presets and customization options.
The founder of Iris gave a speech on TED in which he summed up the benefits of using software like Iris.
Iris is another program that you may use on your computer to combat negative effects of working on a computer all day or night long. The program offers less customization options than F.Lux but it appears to work quite well out of the box.
Now You: Do you use eye protection software on your computer?
