Apple’s latest software update for iPhones and iPads included new animations, but some users are reportedly getting sick over the effects.
“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,” wrote one iPhone user on Apple’s support forums, according to FoxNews.com. That thread has been viewed more than 15,000 times and features dozens of similar reports of carsickness and nausea.
A doctor has also told FoxNews.com that it’s possible that users of the iPhone can become carsick.
"There’s some validity to this, for people who are susceptible," Dr. George Kikano, division chief of family medicine at UH Case Medical Center in Ohio, told FoxNews.com.

Apparently, it's not the zoom animations that are responsible. It's a new "parallax" function that causes the background of the phone to subtly move back and forth, a feature that leads to an effect not unlike car sickness.
ABC News reports that Charles Oman, a former director of NASA's Sensorimotor Adaptation research Team, has studied the origins of motion sickness for more than 15 years. While he doesn’t doubt that people may feel their stomachs churn a little, he's hesitant to call it motion sickness.
"It takes a couple minutes of sustained stimulation to activate motion sickness," Oman said. "If it were an immersive environment, like a headset or an IMAX screen, then I can believe it, but it's a little harder to believe on the small screens."
Some users are holding off on upgrading their devices for now because of the animations.
