The researchers found that individuals with higher self- Page 11 3D MOVIE EXPERIENCES 9 perceived anxiety levels reported more symptoms of VIMS, such as tired eyes and double vision after viewing 3D movies.
In addition to symptoms of visual fatigue, viewers of 3D may experience nausea (nausea, increased salivation, sweating) and disorientation (dizziness, vertigo, fullness of head).
3D imagery causes these muscles to work separately. Such a change in muscle movement can cause eye strain and fatigue to develop. This can lead to headaches, dizziness and nausea. The symptoms can feel quite similar to motion sickness you might get while riding in a car.
This is caused by a “disagreement” between the vestibular system and the visual input, causing that the body interprets it is moving, creating a contradiction with the vestibular system.

How do you overcome 3D sickness?
Keep cool. One of the symptoms of motion sickness in VR is feeling warm or starting to sweat so it's a good idea to open a window or point a fan at yourself while in VR. Not only will this cool you down but it'll also increase air circulation which helps with any symptoms of motion sickness that may arise.
Sit farther back from the screen. Take breaks and get fresh air or a glass of water. Ease yourself into new games, staying active for only 5 minutes at first, then slowly increasing the time you play or watch. Adjust game settings regarding field of view or sensitivity of movement.
“The 3D effect will be felt when the brain successfully combines the shadow that is formed in both eyes. People who have problems in combining the shadows in both eyes, in general will experience symptoms while watching a 3D movie”. Symptoms include headache, blurred vision, dizziness, and nausea.
What will happen if you wear 3D glasses for too long?
It's simply your eyes and brain attempting to work in a different manner to process new images. There's no evidence that viewing too much time wearing 3D glasses causes any long-term eye problems, but it may be uncomfortable in the short-term.
In contrast, people viewing real 3D were much more likely to report headache or eyestrain (around 10%) than people who just thought they were viewing 3D. This suggests that while 3D gives some people a headache, it doesn't really make people dizzy – people just expect it to.
They might feel nausea, dizziness, or disorientation. A new study suggests that these symptoms aren't weakness on the part of the viewer. People who get "simulator sickness" may simply have better 3D motion perception. Several factors influence whether a person is prone to ordinary motion sickness.
Poor Content. A lot of 3D movies weren't very good in any dimension, a lot of 3D sports didn't really work in the format (tennis, for example, was very dull). A new format demands premium content to drive uptake.
They have existed in some form since 1915, but had been largely relegated to a niche in the motion picture industry because of the costly hardware and processes required to produce and display a 3D film, and the lack of a standardized format for all segments of the entertainment business.
A person whose eyes don't accommodate properly will experience blurry vision. The repeated need to refocus vision each time there is a change from distance to near vision, and back again, can cause headaches and eyestrain when attempting to watch 3D movies and shows.
Optometrists say as many as one in four viewers have problems watching 3-D movies and TV, either because 3-D causes tiresome eyestrain or because the viewer has problems perceiving depth in real life. In the worst cases, 3-D makes people queasy, leaves them dizzy or gives them headaches.
This headache is a brain's reaction to the 'wrong' images coming to both eyes simultaneously. The brain needs to combine them to produce a stereo effect, but unfortunately it does not always succeed.
Can I watch a 3D movie if I wear prescription glasses?
In short, the answer is yes, however, if you try to fit a pair of 3D glasses on top of your normal spectacles, you'll soon find out why some people get frustrated. They simply don't fit and are not comfortable at all. There is an answer for this however, you can get yourself a pair of prescription 3D glasses.
For many people who wear glasses, bigger truly is better. Forget about those cheap plastic glasses the theater provides you. For hardcore movie buffs who wear glasses, there's only one way to go: your own prescription 3D glasses.
Even though the lenses in these 3D glasses include UV protection, Polaroid Eyewear doesn't recommend their 3D glasses for extended outdoor use as the different attributes that provide the 3D vision are different from those used for sunglasses with full UV protection.
There are several causes of visual vertigo/motion sensitivity symptoms: Benign paroxysmal positional vertigo (BPPV), labyrinthitis, vestibular neuritis, Meniere's Disease, migraine-related vertigo, head injury, post-concussive, and cervicogenic dizziness/ whiplash-associated dizziness, just to name a few.
This likely happens because of the sensory conflict of seeing the environment move on the screen while the body remains stationary. Watching films in 3D at the cinema can prompt motion sickness for the same reason.
Researchers who study this type of nausea call it cybersickness. Dizziness, headaches and nausea happen while watching 3-D or IMAX movies because the brain receives conflicting information from the senses, said professor Andrea Bubka, who researches cybersickness at St. Peter's College in Jersey City, N.J.
This digital dizziness is called cybersickness or also known as digital motion sickness. This type of dizziness is a problem that takes place in the central nervous system – which manages blood regulation and controls the oxygen flow to various parts of the body, most notably to the brain.
There are three primary categories of cybersickness symptoms: oculomotor issues, disorientation, and nausea. The oculomotor issues are caused by the nerve that facilitates eye movement being overtaxed and leads to headaches, fatigue, and eye strains. Disorientation includes vertigo and feeling dizzy.
