A number of customers who have downloaded the iOS7 software have gone to the message boards to complain about the physical effects of the new design some of which include nausea, dizziness and headaches.
On the official Apple discussion board for using the iPhone, customers say the zoom animations and fake 3D effects have caused them to feel queasy and have "motion sickness."
"The zoom animations everywhere on the new iOS 7 are literally making me nauseous and giving me a headache," one user said. "It's exactly how I used to get car sick if I tried to read in the car."
"I'm now going on day 3 of total nausea," another user complained. "At first I didn't want to believe it's because of iOS 7, but I can't stand even looking at non animation areas for more than a few minutes even typing this."
Unfortunately for them, the software upgrade, which can be downloaded for the iPhone, iPad and iPod Touch, is hard to reverse to iOS6.
The zoom animations can be somewhat managed, however, by reducing the motion in the general settings.
