According to research done by the American Medical Association, exposure to excessive light at night, including extended use of electronic media, can disrupt sleeping and intensify sleep disorders. F.lux makes the colour of your computer’s display adapt to the time of day, specifically dawn and dusk. The warm colours at night can help your eyes adapt and diminish strain. When it’s time to sleep, it will become a much more comfortable transition into a darker environment.
Night-time exposure to blue light keeps people up late. F.lux adjusts colours in a way that reduces the stimulating effect of blue light and the developers have documented the science to prove it!
The science that explains why blue light keeps you up was begun many years ago in the study of bird migration, and it continued in humans with the discovery of a new photoreceptor in the eye, called Melanopsin. Many are familiar with the “rods and cones” that provide our visual capabilities, but it was only about 15 years ago that retinal ganglion cells containing melanopsin, which are sensitive to a narrow band of blue light in the 460-480nm range, were discovered, and their unique effect on sleep was investigated.
When the sun sets, F.lux makes your computer look like your indoor lights and in the morning, it switches back to sunlight again. The options are fully customizable, and you get to choose a strength that works for you. Depending on the amount of windows in your room and type of lightbulbs, your settings could be different than mine.
I’ve been using F.lux for the past six months and now I can’t live without it. I don’t generally have trouble sleeping, but I still feel much more comfortable staying up late, in front of a computer screen. It’s an easy transition from sitting in front of 3+ displays, to laying in bed.
It is always being updated and the latest version of F.lux, released on March 12th 2014, includes some great new features and tricks that I’ll definitely be using more often. Staying up for a movie before bed, pulling an all-nighter, or looking for a Darkroom feel? Version 30.1 has you covered! This update also adds some bug fixes to ensure the app is less resource intensive and perfect for all Macs.
There’s no better price than free and I’m sure you won’t regret trying it! Leave a comment letting me know how F.lux has improved (or impaired) your sleep! Just get f.lux at https://justgetflux.com/.
