Did you know the light from your Mac’s screen, as well as smartphone and tablet screens, is not good for your eyes? The reasons are many and varied but there are ways to minimize a Mac screen’s impact on your health.
First, we need to recognize that not all light is created equal. Blue light, for example, the kind that emanates from the screens on our smartphones and tablets and computers, can be harmful. Apple has added a NightShade feature to iOS 9.x, but here’s a way to add a bit more control over your Mac’s screen.
What Time Of Day Is It?
Since first reading about the blue light problems from LCD screens I began a search for utilities which can help overcome some of the issues (and, I plan to get lenses for my glasses which can block some of the blue light).
One app to try is called f.lux, which runs on Macs, Windows PCs, iPhone and iPad but you won’t find it in the various app stores. What it does may not solve your lighting or screen issues entirely, but it’s a step in the right direction.

f.lux makes the color of the screen match the time of the day. That means warmer at night (less blue) and more like sunlight during the day (also less blue). You’ll need to try it awhile to see, but f.lux might just help you sleep better at night.
Controls and setup are straightforwardly simple and self explanatory.
f.lux automatically adjusts your Mac’s screen to match the time of day; indoor lights for evening, sunlight-like for daytime. Does it work? For me, the jury is still out but I’ve grown used to the softer warm while working late at night (a screen color somewhat matched by NightShade on my iPad), but it hasn’t hurt. My Mac’s screen looks a bit different at night vs. the daytime, of course, but I travel so the time on the clock is not always reflective of the time of day for my eyes.
iPhone and iPad users will be disappointed to learn that f.lux requires your device to be jailbroken as Apple doesn’t want such technology to be used without authorization and approval.
f.lux is free for Mac users.
