Having trouble sleeping at night? One problem might be that you are using your computer before you goto bed. Instead of going into the complex science of eye stimulation (which I do not quite understand myself), I will give you the brief over view. On f.lux’s website they explain it to us that the blue lights that your computer emit can keep you up late at night, so the purpose of f.lux was to eliminate these blue lights. They have done this by making your computers screen adapt to the time of the day. For example, on there website they state: “When the sun sets, it makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again.” Overall, f.lux has personally been a great help with my tendency to work late into the night. So for all of you people out there like me I would recommend downloading f.lux. For more information behind the science of f.lux click here.
