Staring at a computer for hours at a time is “horrible on your eyes,” said Roberto Baldwin in Wired.com. Studies have shown that your monitor’s unnaturally bright pixels are “a recipe for eye fatigue and strain.” Enter f.lux, a free desktop application that claims to save your eyesight. It works by adapting your display’s color temperature to something more natural, depending on the time of day. For example, f.lux adjusts your screen during daylight hours to mimic the cool bluish tinge your brain associates with sunlight. When night falls, the display shifts to produce a warmer, yellower glow that is gentler on your vision, particularly before bed. The app admittedly “takes a bit of getting used to,” said Kevin Smith in BusinessInsider.com. “But if you use it regularly, your eyes will thank you later.” Download the program for free at JustGetFlux.com.
