Are 3D films bad for you?

As 3D content and 3D-enabled devices becomes more mainstream, the health warnings are on the rise. But are 3D films really bad for your health?
According to eye experts there is still no scientific evidence which proves whether the eyestrain, blurred vision, dizziness, headaches or nausea reportedly caused by watching 3D content, will cause long term damage.
Consumer electronic giants, such as Samsung, have issued several warnings relating to the consumption of 3D. For example last year, Samsung said that its 3D TV sets could trigger epileptic fits or cause ailments ranging from altered vision and dizziness to nausea, cramps, convulsions and involuntary movements such as eye or muscle twitching.
Those who have been deprived of sleep or who have been drinking alcohol were also advised to avoid watching 3D television by Samsung.
However, eye experts have questioned the validity of these warnings, and believe that these electronics companies are erring on the side of caution to avoid any potential lawsuits, just in case there are any unexpected side effects of 3D technology.
Gail Stephenson, head of the Directorate of Orthoptics and Vision Science at Liverpool University, said: “There is no decent scientific evidence or research at the moment to show that 3D technology cause any harm to children’s or adults eyes…I think at the moment it is more a case of these technology companies covering their backs in the current world of regular litigation.”
She added: “As with any type of activity done for a long period of time, such as sitting on the sofa while watching TV for hours on end, people may suffer some symptoms afterwards – such as headaches, blurred vision and disorientation. So I think the message to people using 3D technology is not to enjoy it without regular breaks. Whenever we put any of our bodily systems under stress, they react unusually but there is nothing to say there is anything specifically harmful about 3D technology to the eyes of children or adults.”
