3D movies are a fantastic way to captivate an audience, but for those who suffer from vergence accommodation (now called 3D motion sickness) it can be a real nightmare. Vergence accommodation is the name for the mismatched signals your brain receives when your eyes try to process the distance of a virtual 3D object and the focus distance required for the eyes to “place” the object. In many cases, people are unable to send consistent signals to the brain to determine what the object is and how far away it is due to the 3D image existing on a different visual plane than the screen. of real cinema and the constant eye/mind. attempts to recalibrate can lead to headaches and feelings of nausea and dizziness. In some extreme cases, it can even trigger vomiting or, in the case of a man in Taiwan, death.
“Avatar” wasn’t the only example of turn-of-the-2000s 3D to cause this phenomenon, as Nintendo had similar complaints after the release of its Nintendo 3DS handheld console. Entertainment presented in 3D was rare in those days, and most viewers’ eyes had not been bombarded with constant visual stimuli or ultra-high definition images as they are now. Sadly, there’s no “cure” for 3D motion sickness, but society is in a much better place to consume 3D media like the upcoming “Avatar: The Way of Water” than we were. in 2009.
