People are nowadays working on computers for long hours. Health experts say that this can lead to many problems. One of the most affected parts of the human body is eyes. People say the new LCD/TFT monitors are better in comparison with the old CRT monitors. But staring that object for long hours can definitely be harmful, I believe.
Recently I cameĀ across a software(f.lux) which helps to adjust the display setting based on the time. I have been trying f.ux for sometime. I feel it wonderful. I would recommend f.lux to anyone who sits in front of computer for long time. Moreover it costs you only few megabytes of hard disk space and some RAM space.
