Don’t Blame Everything on the 3D, Go Check Your Eyes First

July 20th, 2012 · 3 Comments · General 3D News


Having problems with your eyes can cause problems with properly perceiving 3D and that is a well known thing among people that are either working in producing stereoscopic 3D content or among enthusiasts that are a lot more into the technology than most other people. However a lot of the moviegoers and users that are interested in stereoscopic 3D photography or 3D videography, even stereoscopic 3D gaming may not be aware of that. In fact people having problem with 3D technology, not being able to perceive the full effect or even at all, or feeling negative side effects of watching 3D content such as nausea or headaches can often suffer from some sort of an eye condition that causes the problem. It is possible that the condition may also affect their normal stereoscopic vision, but these people may not be aware of that, though you should not forget that there are other possible causes like badly done 3D that give you bad experiences when watching stereoscopic 3D content. Problems with properly perceiving stereoscopic 3D content can be a good sign that something may be wrong with your eyes and you may not even be aware of that, thinking that what you see is actually what you are supposed to. So next time when you go and watch a 3D movie with friends or family try talking with them how they’ve experienced the 3D effects in it and compare to what you’ve seen…

The issue of experiencing 3D not the way that it is meant to by people with vision problems has also been covered by Barry Sandrew from Legend 3D in his personal blog and I’ve mentioned that here. The good news is that at least some of the people suffering from different eye conditions can go trough Vision Therapy in order to be able to properly perceive 3D in the real world as well as in 3D movies and other stereoscopic 3D content. A good example for that is the personal experience shared by the neuroscientist Dr. Sue Barry in her book called Fixing My Gaze: A Scientist’s Journey Into Seeing in Three Dimensionsk. Another more recent example is Shelli Welter from Minneapolis, who started vision therapy in order to restore her proper stereoscopic 3D vision and be able to enjoy 3D movies they way they were meant to be. And she went further by creating a blog dedicated to her therapy and documenting how it goes step by step. Hopefully this will encourage other people with vision problems, first to find out about them, regardless of their age, and then to go ahead and do something in order to resolve them. And here is a simple and easy Depth Perception Test in order to check if you have fully functional stereoscopic vision or something may be wrong with your depth perception. But even if you pass this simple test this does not mean you may not have an eye condition that can cause problems for your proper stereoscopic 3D vision.

The Importance of Your Eye Health for Stereoscopic 3D Perception

March 15th, 2012 · 12 Comments · Other S3D Tech


I’ve talked about the fact that often getting bad experience when watching 3D content can be due to multiple different reasons, one of the most common being the bad quality of the 3D content, but it actually is only one of the possible reasons. Actually one of the other very common reasons that often gets overlooked is the possibility of the viewer having a problem with his/hers vision. It is not that you might need to wear glasses, even if you are wearing prescription glasses or contact lenses they may not be good for watching 3D, as it also depends on what type of an issue with your vision they are intended to correct. In reality every person sees the world differently and that goes for 3D movies as well and when you don’t have a base to compare you usually blame the content for the bad experience and don’t try to look for the problem in other places… it is simply the easiest thing to do.

The problem can really be inside yourself, and while in 3D movies we don’t have the option to tweak the depth and convergence experience, like in stereo 3D games, you can play with other things that can change the experience at least a bit. But no matter what 3D content you are watching and on what display (also important factor for a good 3D experience) if you have trouble with your vision you might be disappointed from the 3D in overall, thinking that all the 3D content you’ve tried is actually bad, flat or whatever while at the same time the problem might be in you. If you go to a 3D movie or watch one at home that everybody is saying is great and looks simply astonishing in stereo 3D, but you are disappointed from the experience you are getting, that is a good hint that you should go and check your eyes, as most of the time the problem can be resolved if you have some sort of an issue with your vision. Of course it is not necessary that your vision might be the reason for you not getting good 3D experience, and eliminating all the possible setbacks is the only way that you can ensure that you are getting the best 3D experience you can. There is an interesting publication covering more in-depth the subject about problems with vision and stereo 3D over at Barry Sandrew’s blog that you can take a look at if you are interested in how issues with vision could affect your perception of 3D…

Reflections on the Growth of 3D, a Blog by Barry Sandrew

February 25th, 2012 · No Comments · General 3D News


Reflections on the Growth of 3D is the name of a new blog by Barry Sandrew, the founder and president of Legend3D – a company specialized in 2D to 3D video conversion technology. In his blog, Barry Sandrew shares some interesting information regarding 3D movies and the science behind seeing them with the added perception of volume. And although the blog is still quite new with just a few publications as of the moment, hopefully there will be more made available in time, so definitely a place to look at. You can also follow Barry Sandrew on Twitter as well.
