A recent report by the Eyecare Trust says that 12 percent of U.K. citizens cannot view 3D images due to poor binocular vision. The charity says that “3-D technology relies on our eyes’ ability to work together as a co-ordinated team to achieve an accurate perception of depth.”
“However, more than one in ten of us (12%) has a visual impairment that means our brains are unable to correctly process the individual images that are transmitted to it via our left and right eyes,” the report says. “This leads to an inconsistency in viewing the three spatial dimensions (height, width and depth) required to enjoy 3-D films in all their glory.”
Sony Computer Entertainment recently updated their Terms of Service to include health warnings about 3D technology.
“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. If you experience such discomfort, you should immediately discontinue use of your television until the discomfort subsides,” the document reads.
“SCEA 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.”
This follows increasing health concerns over viewing 3D content, especially at a young age. An article at Audioholics (via GamePolitics) reviews some issues that can occur including strabismus, a condition where stereoscopic vision is severely compromised. Strabismus, also called lazy-eye, is an abnormal alignment of the eyes leading to poor depth perception. Children up to the age of seven are at high risk of falling prey to the condition while consuming excessive amounts of 3D content.
