If you’ve been experiencing mysterious headaches, it could be your phone.

Feeling car sick lately? If you’ve got an iPhone, that could be the problem. 

Users were warned that the new iOS 7 software and it’s parallax effect could feel weird - and for some, it’s a real problem. Headaches and nausea are the primary complaints. People who are sensitive to motion sickness, 3D movies or Imax films are most likely to feel iSick from their iPhone or iPad. The subtle 3D effect can throw your vision and inner ear balance mechanism slightly out of sync, resulting in - blech! 

There is a setting to reduce motion which may help a bit, but there is no way of getting rid of the parallax effect completely on iOS 7.
