Are you the sort of person who uses a computer? And are you the sort of person that can have difficulty getting to sleep? I stumbled across F.lux, a simple programme that automatically adjusts the temperature of the colour on the screen, adjusting it to the time of day resulting in less strain on the eyes and it could help you get to sleep better.
Since computer monitors are basically meant to replicate the sun in their performance in colour management, at night they can blind you for being too ‘white’. F.lux, changes the colour temperature to be yellower or more sepia reducing stress on the eyes.
Whilst I cannot say for sure if it works or not at the moment as I have only been using it for a few days, it definitely does change the colour balance, but if you are working on the computer, you won’t really notice it at all as it is done gradually.
Below is a screenshot of the preference window, I can’t show what the colour difference is between midday and midnight as that can’t be captured in a screenshot. For those interested, here is a link to the F.lux website: Here
