3D Movies Can Make You Sick

Watching 3D movies can "immerse" you in the experience, but it can also lead to visual symptoms and even motion sickness. Symptoms related to 3D viewing are affected by where you sit while watching, and even how old you are.

Researcher by Shun-nan Yang says, "Younger viewers incurred higher immersion but also greater visual and motion sickness symptoms in 3D viewing. Both problems will be reduced if a farther distance and a wider viewing angle are adopted."

When two groups of participants watched the same film--one group in 2D and the other in 3D--21% reported symptoms of motion sickness while watching the movie in 3D. Movies shot with handheld cameras often produce the motion sickness as well. For younger study participants blurred vision, double vision, dizziness, disorientation, and nausea were all more frequent and severe when watching the movie in 3D.

As 3D movies become more common, including on home screens, there are reports of visual and other symptoms among 3D viewers. Vision and orientation symptoms related to 3D viewing may be related to a "mismatch" between focusing and converging the eyes.

There's always somebody who wants to spoil our fun, but NOBODY can spoil the fun of our subscribers, because we have something special for them every week and we save the best for them!

One of the main reasons that viewers of 3D movies experience eye-strain, is because the directors insist on using the cinematic device of narrowing the depth of field to highlight a key area within the frame. This may be relevant to 2D movies...after all, we are all used to seeing photographs where only the subject is in focus...but for a 3D scene this is completely unnatural. Just image looking around you and seeing everything out of focus, apart from the person talking directly in front of is obvious that this would give you a headache, if you continued to look away from the main subject. The trick, of course, with 3D movies that still use this technique, is to only look at the areas that are in focus! In another words, you have to follow a rule that no one has told you about...a rule which the director assumes you have inherited from the 2D cinematic and photographic world.

So in my opinion directors have a bit of catching up to do with respect to 3D, so the experience is as close to a real-life one as possible for the viewer. After all, why do we need to be 'told' where to look?

Any eye-strain is revealing you are low in taurine, an important amino acid which reduces in quantity in the brain with age and is assimilated with the aid of light.......eye-strain is revealing how badly we are being fed by today's mass produced food.

I experience no eye-strain watching 3D movies, it is not a question of blaming the movies, people are needing better diets - I take loads of health food supplements, if you're taking a taurine supplement you need to balance it with glutamine, which makes me sound like a sales rep, but it's true - if you only swallow glutamine, your eyes will get even sorer - balance it with taurine, and your eyes and brain will improve. I don't stick to the rules - I swallow about 8 capsules of each amino acid every so often.

I'm used to 3D, been shooting 3D videos since 2008 and got a 3D TV. But "firsttimers" can get a little motion sickness I've noticed. The movies are not flat lol. 3D is more natural than 2D because reality is in 3D. Sit close to the centerline in the back and avoid the bad 2D to 3D conversions like "Clash of the Titans". They contain too many imperfections causing eyestrain. Sony has made an excellent cheap 3D camera "Sony 3D bloggie" at around 250$ and most newer TV's can show 3D video and pictures. "Magix Movie Edit Pro 17 PlusHD" costs 30$ and can turn Your 3D videoclips into a HD 3D movie in 10 min. Anyone who wants 3D trailers should go to and download them.
