Strain your eyes less while studying with this helpful program.

It’s been said time and time again that long-hours spent in front of the computer screen is a good way of causing eyestrain, and even makes it more difficult to sleep. By flooding your eyes with light, you’re more likely to stay awake longer than you would in a low-light condition, as our eyes are simply programmed to equate the presence of light with the need to be awake. Evolution has yet to catch up with our predilection for late-night cram sessions. The advent of mobile technology isn’t helping either, as more and more people tend to use their smartphones or tablets while lying in bed.

Luckily, f.lux is a great solution to this problem. This free program, which uses very little RAM or disc space, is built to counter the harmful effects of the bright screens we continously have in front of us at night. It works through use of a filter that adjusts the brightness and color of your monitor according to your location and the time of day automatically, matching daylight during the daytime before adjusting to halogen or fluorescent light levels (depending on which you use) after sunset.

The transition is also gradual enough that it’s almost impossible to notice the change as it’s occurring. Additionally, students doing color sensitive work may temporarily disable it for an hour before resuming its cycle. Alternatively, people who work nights and sleep during the day may flip the cycle around, helping you get to bed whenever you please.

As someone who spends long hours in front of a computer every day and a lifelong insomniac, I can personally attest to just how helpful f.lux is in getting you to bed more easily and reducing the headaches that come from hours of studying.

The program is available for Windows, Mac, Linux, and the iPhone/iPad.
