Apple’s new operating system iOS 7 is making users sick.

The moving background on the new system – released for iPhone and iPad last week - has been causing some users to complain of motion sickness.

In iOS 7 when you move the phone or tablet left and right, or up and down, a parallax effect causes the homescreen icons to ‘float’ over the background. In addition, when you launch an app it leaps out from the homescreen, zooming back in  when you close it.

The effects appear to be making some users nauseous and unhappy iOS users have taken to the Apple Support Communities to vent their frustrations.

One user, with the user name Ensorceled, said: “The zoom animations everywhere on the new iOS 7 are literally making me nauseous and giving me a headache.  It's exactly how I used to get car sick if I tried to read in the car.”

Ajax324 reported the same problem. “After using it for two minutes, I felt nauseous. It's the same way I feel when I use spaces on my Mac,” the user wrote.

And a third, Ldejeant, said: “I have the same problem. It hurts my eyes and makes me dizzy.”

Other users have complained of vertigo and one even claims to have gone home sick from work due to the intense nausea caused by their new iPhone.

Heading to Settings > General > Accessibility > Reduce Motion lets you diminish the parallax effect, but according to one user, Apple support has said there’s no way of turning off the animations completely.

Some users have resorted to downgrading their software from iOS 7 to iOS 6 – which is a fairly technical process that won’t appeal to everyone.

According to technology website The Verge, Apple has yet to comment on the complaints.

We’ve been using iOS for a week and haven’t had any issues. But do you have iOS 7 on your iPhone or iPad and have you experienced motion sickness? Let us know in the comments below.
