Update On My Blue Light Screen Filter Experiment

Posted Aug 17 2011 1:18am

I commented two weeks ago on how modern computer displays (particularly LED backlit monitors) emit a very high amount of blue light, which can be very stimulating. Any kind of light in the hours just before sleep can delay the circadian clock, as well as to suppress melatonin levels, which can delay sleep onset. I installed a program on my laptop called  F.lux , which removes the blue tinge on my screen only in the evening hours. 

I’m happy to report that I’m able to fall asleep much earlier now. Overall, I’m feeling more refreshed when I wake up, and generally have more energy during the day.

If you have to work on your computer late in the night, try downloading and testing out this free and simple program . In this age of overstimulation and too many distractions, we can use any help that we can get. After using it for a few weeks, please report back to me your experiences.
