Invert the iPad or iPhone Screen to Make Reading at Night Easier on the Eyes

If you’re like me you end up reading a fair amount while laying in bed using an iOS device. If you read in the dark, you can give your eyes a rest by turning on a little known Accessibility feature that inverts the display of the iPhone, iPad, or iPod touch to show white text against a black background rather than the default setting.
Enable Screen Inversion on an iPad or iPhone
- Tap on “Settings”
- Tap “General”
- Choose “Accessibility”
- Look for “White on Black” and drag the slider to “ON”
You will immediately see the change, which looks just like the screen shot above. I find this much easier to read with than just reducing the brightness, although it’s not quite as good as something like Flux for the desktop. Yes there’s an iOS version of Flux available, but it requires a jailbreak so that’s not a viable option for everyone.
Inversion has been around since at least iOS 4, and while it’s intended for those with vision issues it can also just be a great relief to those of us who read in the dark. It’s also kind of fun to try and play games with the screen inverted, or just to turn this on a friends iPhone as a prank.

I set my brightness to almost zero so I can still have accurate colors
Yeah but unfortunately there’s still no quick way to adjust brightness. Using the three-click option to do this inversion you can turn it on and off almost instantly.
actually there is a pretty quick way to adjust brightness…
when you use the double click to see what apps are open, if you swipe the bottom row of apps to the right there is a bar that lets you adjust the volume and the brightness…pretty easy and quick
You can also program this to come on with a triple-press of the home button. Quick and easy to turn on and off.
That is brilliant. Makes the tip actually worthwhile. Thanks dude!!
My friend has it setup for his MBP to happen in low light so the triple click is close enough for bed use
On a Mac you can also apply this by pressing
Control-Option-Command-8
Ive been using Flu.x since i read about it here, and let me tell you, it is amazing!! It does exactly what it says it does: reduces stress on the eyes. The bright white light of my laptop was really bad on my eyes, now not only do i have it on my macbook, i have it on my jailbroken iPhone and PCs with Windows and Linux.
Many reasons made the invert color good,
for better batterie (if more black)
better read,
some who want steel your iPhone think it’s broken.
One of the funniest pranks to play with a mac owner (or at a retailer..) is to press ctrl-alt-cmd-8 to invert the display. Not many people know how to reset this (repeat key-combination).
Great!….BUT, it also inverts colors in your pix! Why?? It makes no sense to me why I would want to look at my pix turned ‘infrared’.
