Does watching 3D video cause eye strain, headaches, fatigue etc - is it bad for you?

Anyone suffering from eye strain from those heavy 3D-sessions?

No,do you?

I think 3 hours is as long as I've gone at a time, mainly due to the glasses getting uncomfortable by then. I've never had any strain from it. Now staring at a computer screen all day, yes, that definitely gives me eye strain.

hehe it's a no from me also

Having spent best part of 25K I really didn't find this 'dramatic advancement in technology' *Coughs* so moving that I should step up a level. I am not interested in slinging out my reciever/projector exectra to enable a thing, deep down I must be envious of.

I tend to agree about 3D viewing causing tired eyes, fatigue. I can watch a 2 hour movie in 3D, but then I am ready to take off the active 3D glasses. I haven't had my 3D setup that long (about 2 weeks) so I am not sure if it is a matter of getting use to it or if it is an issue in watching too much 3D movies. I guess trial and error will determine the results (wait and see).

Similar research also found being awake causes eye stain and fatigue as well.

So does reading or riding a bus.

If you spend a long time awake you may get hungry or thirsty too as well as fatigued.

I hate that part where I get hungry and have to spend money on food that I could be spending on more fun things. Like more 3D movies lol.

I had a friend over a while back for a little 3D marathon. It didn't bother my eyes any. Lets see. We watched How To Train Your Dragon. Monsters vs Aliens. Cloudy With A Chance Of Meatballs. A couple of Imax documentaries. Some of Open Season. Some of Ice Age.

So why bother posting in this thread then?

Re-read the part quoted.

Everyone who "hates" 3D is someone who can't afford 3D.

Never had eyestrain or a headache when watching a 3D movie, though there were a few shots in Cave of Forgotten Dreams where something would pass by the camera and it would be disorienting. I think watching Transformers 3 in 3D would give me a headache for non-3D-related reasons

Brian,

I was actually gonna write something similar,didn't want to hurt Gunz feelings,though...

after all,I'd be plenty miffed,having 25k worth of last-gen gear at home.

What's the common jokes again to those who said they had eye strain? "You have to put on the glasses!"

But wait there's more. "You have to power on the glasses."

If only people who went to the demos at Best Buy knew those 2 things, there will certainly be no eye strains.

Fatigue is a totally different animal. If you've worked all day and at end of the day, decided to watch a movie -- be it 3d or not, most likely you'll succumb to fatigue and fall asleep, especially if it's a boring film.

Are you sure you read all the article ????

[GunZenBomZ]

Can't read the article or other links on the web for it. Seem's even though I fking pay & have helped make the BBC, I am not allowed to read the site. Such shyte now-a-days

It is a 4 page article so I will just add a synopsis. A neuroscientist (Bruce Bridgeman) with almost stereoblindness due to lazy-eye went to see a film in 3D with his wife, at wich point he ended seeing 3D for the "the first time" when he left the theatre he had stereovision. The article then goes into explaining whjy stereovision is important and some documented research on the subject (not 3d films but how some test material had helped give some stereoblind/stereoimpaired vision people their stereovison back asas well as some conjecture on why this works)

Thankyou AP for a clear breakdown on this interesting situation. Hope this method triggers further help & research for others suffering lazy-eye syndrome.

My wife has a lazy eye due to a severe vitamin B1 deficiency caused by gall bladder illness several years ago. It typically only kicks in when she is very tired or has had too much to drink.

We recently got a 3D bluray player and tv and she swears that she can see 3D movies much better, and that she doesn't have to "work" to see them. It has not however miraculously cured her eye issues, but I am glad that she is able to enjoy the home theater more than she used to.

Glad to hear that she is able to at least enjoy 3D. It most likely hasn't helped her condition much because it is a deficiency problem, not a neurological problem. I think it helped that one guy because his brain wasn't triggering a certain receptor, and 3D movies taught it how to pull the other eye into focus.

I seen you would notice my enjoyment of 3D movies is better at home than in the theaters.

When I saw The Hobbit part 1 in theaters the 48 frames per second was obvious but the 3D was less so. At home it was better.

For my mom it's an issue of a headache versus no headache.

My mom got a headache in the first 5 minutes of The Hobbit part 1. She had other similar 3D headaches before.

But when I showed mom Wreck-It Ralph 3D at home she stayed for 20 minutes and only quits because she didn't understand the story not because she got a 3D headache.

I could probably explain it by the fact that typical polar base 3D used in the theaters does not work unless you are very statuesque when watching films.

I don't know how sensitive these films are but if you inadvertently tilt your head more than a couple of degrees to either side you cause Double exposure in both eyes, which causes confusion which causes 3D headaches.

However the shutter based 3D that I always use I can sit through two three hour movie and not get a 3D headache once

Some companies want to lock 3D exclusively in theaters. As we know theaters make more sense to have polar base 3D just because the sheer number of viewers and the fact that they keep recycling every 2 hours makes that the more efficient form of 3D in the theaters.

However at home at most you're serving one or two people and they're the same one or two people each time that come and watch therefore you can spring for the battery powered glasses and you don't have to worry about germs being spread, even before covid, that would be present if you passed around active glasses every 2 hours to the next audience.

If they lock 3D movies exclusively to theaters, then there's no point in making 3D movies because the 3D is not that great in the theater.

Now some people may argue that they get a 3D headaches from shutter based 3D. I never heard of someone but they don't have to engage in shutter base 3D if they want to engage in 3D movies as they have home options for Polar based 3D.

But the other way around there's no alternative the only way I could see 3D would be through polar base 3D and that is the inferior technology for my eyes. I've been thrown out of the movie many times by 3D confusion, though I don't get headaches by it, it's not a pleasant experience to just be smacked upside the head with a realization that that 3D picture did not add up well.

Trust me, no one's going to build a communal theater that operates on shutter 3D.

Yet shutter 3D is the technology you could add to your own existing 2D TV if we could solve the timing issue, which I think we can with HDMI ARC.

The ping time is so quick between a Retrotink 2X Pro M plus a typical Amazon HDMI to VGA converter that I was able to play a Sega Master System game on my VGA CRT.

That TV was not meant to play 3D but it did. The secret to getting it to work is sinking the 3D glasses sinker with the actual output on the TV which should be possible with HDMI ARC.
