F.lux the App for Blue Light Syndrom

Have you found that your sleep schedule is less than stellar?  If you are working from home like a lot of us do, you probably find that you are up in the wee hours of the morning writing out that last email.  Your eyes hurt and you might even have a headache.  Recently I ran across f.lux.  This application will record your time zone and adjust your computer or phone screen based on the location of the sun in the sky.  The best part about this is that you don’t have to remember to turn it on or off. It is fully automated so you can set your parameters and let it do it’s thing.  Too many times have I stayed up to 2 a.m. unaware my computer screen affected my sleep pattern.  At sunset, the app will throw a warming filter over your LCD for a calmer mood and less stress on the eyes when everything around you gets darker.  It causes less strain and fewer headaches during long sessions on the computer.  The name of the app is a play on the word lux, a unit of luminous emittance. Computer screens are designed to look like the sun.  Naturally the sun tends to keep us awake during the day and staring at your computer screen at night is like staring at the sun.  It is going to keep you awake, that is where f.lux comes in.


The Science of F.lux

The American Medical Association has this to say:

“Recognizes that exposure to excessive light at night, including extended use of various electronic media, can disrupt sleep or exacerbate sleep disorders, especially in children and adolescents. This effect can be minimized by using dim red lighting in the nighttime bedroom environment.”

In our eyes we have a photopigment found in ganglion cells called Melanopsin.  Melanopsin is most sensitive to blue light and has been linked between light sensitivity and migraines.  The goal of flux is to change the blue light to a warm orange color so that your body can transition from day-to-night more naturally while you continue to work.  I recommend that you do some research of your own into Melanopsin and some the experimental cases that have been done on Melanopsin, and F.lux websites.
