Sony has updated its Terms of Service for the PlayStation 3, taking into account its new 3D capabilities and providing some stark warnings for those who want to indulge in the experience, IGN reported Tuesday.

"Some people may experience discomfort (such as eye strain, eye fatigue or nausea) while watching 3D video images or playing stereoscopic 3D games on 3D televisions," read Sony Online's amended terms.

The notice went to say that Sony "recommends that all viewers take regular breaks while watching 3D video or playing stereoscopic 3D games.

"The length and frequency of necessary breaks may vary from person to person. Please take breaks that are long enough to allow any feelings of discomfort to subside. If symptoms persist, consult a doctor."
