If you spend as much time looking at a screen as I frequently do for work and play, you’ve probably experienced eyestrain. Lucky for us, Stereopsis has created a nice little free app that makes that screengazing easier on the eyes: f.lux. F.lux uses your location and lighting settings to adjust the brightness and color of your monitor throughout the day. Now that I’ve acclimated to using it — I even use it for gaming — turning it off makes my eyes burn.
Do yourself a favor: Get f.lux and go easy on your eyes. It’s available for Windows, Mac, Linux, and iPad/iPhone.
