More About the Possible Health Risks Associated With Stereo 3D

August 12th, 2010 · 10 Comments · Other S3D Tech


At the moment a lot of people are concerned about the possible negative effects that watching stereo 3D content might possibly bring, and there are even speculations that it could even lead to permanent damage to the viewer’s eyes if watching too much 3D content on a daily basis. It is true that there haven’t been too much tests regarding this being done, but there are also no cases that confirm that watching stereo 3D content can lead to some health risks. Actually the only real concern is for small kids while their eyes and brain are still being developed, so maybe just in case you should be careful there is you have children. Other than that you can experience some short-term lets call them side effects from watching stereo 3D content like a movie, TV show, playing a game etc. and at least half of the time the reason for you getting uncomfortable, your eyes feeling tired, getting disoriented etc. is due to being exposed to badly shot or converted 3D content.

But beyond those short-term effects is there risk of permanent eye damage from exposing eyeballs to the faux third dimension for prolonged periods of time? That is what Gamasutra has asked a specialist – Dr. Mark Borchert, a respected L.A.-based ophthalmologist with the American Academy of Ophthalmology and here is what he answered:

It’s not likely to cause any permanent harm to vision. There are people who get uncomfortable with it, and get eye strain or headaches, or on much rarer occasions, a sense of imbalance or nausea, but there’s no evidence it can cause permanent harm to your vision or use of both eyes together or anything like that.

However while Borchert admitted that ophthalmologists “don’t have an answer” to the negative effects of 3D effect viewing on young children, the expert pegged the appropriate 3D viewing age even lower than Nintendo.

Binocularity and stereoscopic vision is something that is learned in the first few years of life, primarily in about the first three years of life. So it’s unlikely that children at that age, where stereoscopic vision is developing most critically, are going to be playing these games. But the effect of 3D on young children, we have no idea. For older children, it’s not going to hurt them. I can’t imagine how this is going to cause any kind of permanent harm to someone who is over four years of age.



Here I can personally confirm that being exposed to “fake” 3D content on computer screens, HMDs, paper prints and other sources for years I have no problems with my normal stereoscopic vision whatsoever, but then again I’m also well over three years old. And regarding the uncomfortable and more tiring first experience that most people have when they watch some 3D content for the first time, there is another scientific explanation, but simply said the main reason is that it is something new, and our eyes and brain need some time to adjust to it. So you should not get discouraged about watching stereo 3D movies or playing games in stereo 3D mode just because you first experience was a bit uncomfortable, try again a few times and if you still don’t get used to it, then you might have some trouble with your eyes or something else, so you should go and see a specialist just in case.

And now what is the actual and a bit more technical reason for the first maybe not so comfortable experience of some 3D content when you are exposed for more than a few minutes. The way that out eyes normally work is that they perceive the depth we are seeing by converging our eyes at an object we want to focus on based on the distance to it – for close objects they converge more and for more distant objects they may even remain parallel. And this movement of the eyes is achieved by the extraocular muscles of which each eye has six, and these muscles are responsible for it’s movement and depending on the distance to the object you are focusing on the eyes need to move in order to converge with the right angle. Then you also have the eyes focus differently depending on the distance to the object you converged your vision on and that is done by changing the curvature of the lens inside your eyes with the help of the ciliary muscles. These two things happen together in order for us to perceive the depth of real world objects in the real life when we are not watching stereo 3D content on out computer or TV screen…

However when watching 3D content on a screen there is something different and new to out eyes and brain and that is exactly what tires you at first, because you need some time to adjust to the new “sensation” and learn how to properly do it. You can even say that your eye muscles need to be trained too, although it is not only up to the muscles not being ready for the additional load they need to handle when watching stereo 3D content. As already mentioned while we are babies and small kids our binocularity and stereoscopic vision is being developed and we learn how to see and perceive the distance and depth of everything in the world around us. And since we use the method described above in the real world and try to apply the same when watching stereo 3D content on a flat screen, we try to do things the same way at first, but in case of “fake” 3D content displayed on screen there is something different. Normally when you are watching an object at a distance of lets say 10 meters away form you, your eyes are first converging for that distance of ten meters and then they focus for the same distance of 10 meters. However when watching a stereo 3D movie or playing a game in stereo 3D mode our eyes are still having to converge for a different distance depending on what content is being currently displayed on the monitor (lets say the 3D screen is 1 meter away from the viewer), so if you get an object that appears deeper inside the screen your eyes will let’s say converge for a distance of 3 meters or if something jumps out of the screen they will converge for lets say half a meter. So this way the first part is the same, our eyes still converge differently depending on the sense of volume (depth or pop-out) we have of the objects displayed on the 3D screen although the screen is actually sitting at a fixed position. However regarding the distance that out eyes need to focus at, depending on the object being displayed on a 3D screen, things are a bit different compared to the real world, as if you converge on an object that is 3 meters away from you in the real world your eyes will also focus for a 3 meter distance. But when you are watching the same thing on a 3D display your eyes will still converge for a 3 meter distance, but the focus you will get will not be for 3 meters like in the real world, but will instead remain at 1 meter – the distance to where your 3D monitor is. Now this is the exact reason that at first the stereo 3D content feels a bit weird, unreal and tiring for our eyes and brain, but after watching a second or third movie or trying to play a game for a few times in stereo 3D mode we adjust and we can easily do this different way of seeing things without feeling strain.

And now comes the role of bad 3D content like movies that were converted from 2D to 3D and that conversion hasn’t been properly made. Going to such a movie can have all the bad effects you’ve felt the first time when you watched some stereoscopic 3D content and in result can create a bad image for the movie (which is to be expected), but also can draw away people from stereo 3D in general usually because of them not knowing the difference between good and bad 3D and/or not knowing that they have actually watched a movie shot in 2D and then badly converted in 3D. The problem with bad conversions to 3D is that generally they contain contradicting depth cues or objects that our brain tells us that should be closer to us, but our eyes tell us just the opposite – that they should be very far form us. This again leads to some additional strain for both the brain and the eyes that are contradicting each other, but there can also be a lot of other factors that can lead to bad experience like jumping through fast scenes all the time with very far and very close objects with our eyes having to readjust to these changes too quick and too much and so on. And then again there should be no health risks associated with watching even badly converted 2D to 3D content, it just leaves a long term bad experience and may as well drive that person away from 3D for a while. However bringing small kids younger than 3 years to watch a badly converted 2D to 3D movie, or exposing them to an autoconverted 2D to 3D TV show or a movie at home on the new 3D HDTV is definitely not a good idea!

New Facebook Group: STOP the 2D to 3D Conversion Madness NOW!

August 5th, 2010 · 5 Comments · 2D to 3D Conversion


Here is one new and interesting Facebook group that is trying to raise the awareness that 2D to 3D conversions are not as good as true stereo 3D and to promote to stop labeling 3D conversions as 3D movies with the viewers not being aware of that fact. So if you support that idea, then you should go and join the STOP the 2D to 3D Conversion Madness NOW! Facebook group. And while I personally too prefer to watch true stereoscopic 3D movies instead of conversions from 2D to 3D and here I would especially stress on the BAD conversions, because I’m not completely against 2D to 3D conversions. Not against, but if only they are properly made and the users are informed that they are going to in fact watch a movie that has been converted to 3D and not being shot in stereo 3D as we deserve to know that from the movie poster and other promotional materials and not having to dig up the Internet to learn that. Don’t forget the fact that in order to get stereo 3D versions of some classic movies like Star Wars for example the only choice will be to use 2D to 3D conversion and taken enough time and resources in order to do the conversion to 3D properly they can become worth watching again in stereo 3D and the viewers will really enjoy them.

Of course some new movies can as well benefit from 2D to 3D conversion, but just a few titles and they need to properly go from the start with the idea that they will be converted later on, so that the whole process of actually making the movie can be done right and the end result when the quality 2D to 3D conversion is finished will be hardly indistinguishable by the viewers, so they will feel like they are actually watching a movie that was actually shot in 3D. Of course even in such cases they should be aware that they are in fact going to watch a conversion, but knowing that and seeing a good 2D to 3D conversion will not disappoint them, as currently with all the 3D craze going around everyone is rushing things doing bad 3D conversions and advertising the movies as 3D… making the viewers think they will be getting the whole Avatar 3D treatment again, and then they leave disappointed. Hollywood is trying to make some quick bucks from the interest in 3D still high because of Avatar, but they seem to be thinking short term only, however that way of thinking may kill 3D again as similar things have happened already a few times if we look back at the history. And this time the reason can be the pure greed of a bunch of people and not the lack of proper technology or resources etc, and all of us – the real 3D enthusiasts do not want that to happen!

Check the list of all the 3D conversions and true stereo 3D movie releases for this year…
